well the intercepts are (8,0) and (-4,0) its a lot of math so you need to find it i would show you but i have a quiz
im not sure tho soo
Answer:
The x-intercepts of the quadratic function are 8 and -4.
Step-by-step explanation:
The given function is
[tex]f(x)=x^2-4x-32[/tex]
Equate the function f(x) equal to 0, to find the x-intercepts of the quadratic function.
[tex]f(x)=0[/tex]
[tex]x^2-4x-32=0[/tex]
The middle term can be written as -8x+4x.
[tex]x^2-8x+4x-32=0[/tex]
[tex]x(x-8)+4(x-8)=0[/tex]
Take out the common factors.
[tex](x-8)(x+4)=0[/tex]
Using zero product property,
[tex]x-8=0\Rightarrow x=8[/tex]
[tex]x+4=0\Rightarrow x=-4[/tex]
Therefore the x-intercepts of the quadratic function are 8 and -4.

A airplane travels at 150 miles per hour the number of hours at that rate is h what is an expression for the number of miles traveled?
Final answer:
The expression for the number of miles traveled by the airplane is 150h.
Explanation:
The expression for the number of miles traveled by the airplane is 150h. This expression represents the distance covered by the airplane based on the number of hours, h, it has been traveling at a speed of 150 miles per hour.
The expression for the number of miles traveled is [tex]\[ \text{Distance} = 150h \][/tex].
To determine the number of miles an airplane travels given its speed and the duration of travel, we can use a basic formula from physics that relates distance, speed, and time. The formula is:
[tex]\[ \text{Distance} = \text{Speed} \times \text{Time} \][/tex]
Here, the speed of the airplane is given as 150 miles per hour, and the time is represented by ( h ) hours.
Step 1.Identify the given values:
Speed ( v ) = 150 miles per hour
Time ( h ) = number of hours
Step 2. Apply the formula for distance:
Distance ( d ) = [tex]Speed (\( v \)) \(\times\) Time (\( h \))[/tex]
Step 3. Substitute the given values into the formula:
[tex]\( d = 150 \text{ miles per hour} \times h \text{ hours} \)[/tex]
[tex]\( d = 150h \)[/tex]
Thus, the expression for the number of miles traveled by the airplane, when it travels at 150 miles per hour for ( h ) hours, is:
[tex]\[ \text{Distance} = 150h \][/tex]

10π
20π
50π
100π
Answer:
100π
Step-by-step explanation:
step 1
Find the circumference
The circumference is equal to
[tex]C=2\pi r[/tex]
we have
[tex]r=10\ in[/tex]
substitute
[tex]C=2\pi (10)[/tex]
[tex]C=20\pi\ in[/tex]
step 2
we know that
An object moves along a circular path and makes 5 revolutions in 1 minute
Remember that
[tex]1\ rev=2\pi r[/tex] ----> circumference of the circle
therefore
[tex]5\ rev=5(20\pi)=100\pi\frac{in}{minute} [/tex]
a newspaper is curious about the satisfaction of their readers. when a person visits the newspaper's webpage, they are asked to complete a brief summary online. Biased or Unbiased?
A newspaper asking readers to complete a survey on their webpage is not conclusively biased or unbiased without knowing more about the survey's design and intention. Surveys can be a method to engage with and understand the readership better, but the potential for selection bias and the phrasing of questions could introduce bias. Whether the survey is biased or not depends on its execution and underlying methodological rigor.
Explanation:The question "Is a newspaper asking readers to complete a brief survey on their webpage biased or unbiased" revolves around evaluating the intentions and methodology behind collecting reader satisfaction feedback. Given the nature of the survey is to collect feedback directly from readers on the newspaper webpage this can initially seem like a genuine effort to improve their service.
For evaluating the unbiased information based on research, it is crucial to consider the intent behind the survey and the potential for selection bias. It might inadvertently capture only the opinions of those willing to participate, or primarily those with strong opinions, positive or negative. Despite these considerations, the effort to engage with the readership directly can also be seen as a step towards transparency and improvement, indicating a potential to balance partiality with constructive feedback.
However, to ensure the process is unbiased, the newspaper would need to follow rigorous methodological standards, like random sampling, to ensure that the survey findings reflect the actual population of readers accurately. It's also essential to ensure that questions are phrased neutrally to avoid leading respondents towards a particular answer.
3+-√(-3)^2 - 4(5)(-1)
It's for a quadratic equation, I want to know how to plug it into teh calculator. would it be -4(5)(-1) or 4(5)(-1)
Answer:
Step-by-step explanation:
Easy way to do this is step by step. Your quadratic, from your entry, must be
[tex]5x^2-3x-1[/tex].
Step by step looks like this, one thing at a time:
[tex]x=\frac{3+\sqrt{(-3)^2-4(5)(-1)} }{2(5)}[/tex] becomes
[tex]x=\frac{3+\sqrt{9-(-20)} }{10}[/tex] becomes
[tex]x=\frac{3+\sqrt{9+20} }{10}[/tex]
and this of course is
[tex]x=\frac{3+\sqrt{29} }{10}[/tex]
Do the same with the subtraction sign to get the other solution.
If you're unsure of how to enter it into your calculator, do it step by step so you don't mess up the sign. If you enter it incorrectly, you could end up with an imaginary number when it should be real, or a real one that should be imaginary.

Answer:
13.74
Step-by-step explanation:
the top right angle is 90 (opposite angles in a quadrilateral add up to 180). use the sine rule. x = 47/sin 90 × sin 17
= 13.74
Answer:
x = 13.7
Step-by-step explanation:
The angle at the top of the triangle = 90° - 17° = 73°
The left side of the triangle is x ( opposite sides of a rectangle )
Using the cosine ratio in the right triangle
cos73° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{47}[/tex]
Multiply both sides by 47
47 × cos73° = x, hence
x ≈ 13.7
Which of the following characteristics of experiments are not also characteristics of surveys?
Check all that apply.
A.
Data are gathered during the course of the study.
B.
Two or more treatments are compared in the study (possibly including "no treatment").
C.
One or more treatment groups and a control group are included in the study.
D.
The results of the study are analyzed statistically.
E.
Replication with other groups of subjects can improve the reliability of the study.
Experimental studies compare B. Two or more treatments are compared in the study (possibly including "no treatment" and C. One or more treatment groups and a control group are included in the study.
Regarding the characteristics that experiments have but surveys do not, the options that apply are that two or more treatments are compared in the study (possibly including "no treatment and one or more treatment groups and a control group are included in the study. These characteristics are specific to experimental design. In an experiment, there is a deliberate manipulation of variables to test a hypothesis, often involving a treatment and a control group to establish causality.
Surveys, on the other hand, typically gather data at one point in time or over time without manipulating variables, as seen in longitudinal or cross-sectional surveys. The two methodologies are distinct in that experiments can provide causal conclusions due to their internal validity, while surveys, although helpful in understanding correlations and trends, cannot as readily establish causation.
5) Find the equation of the line graphed below in Slope-Intercept Form. (3 points)
6) Find the equation of the line graphed below in Point-Slope Form. (4 points)
5. Slope intercept form is written as y = mx +b, where m is the slope and b is the y-intercept.
Using two of the points on the graph find the slope:
(0,-3) and (6,1)
Slope = change in Y over the change in X:
Slope = (1-(-3) / (6-0) = 4/6 = 2/3
The y-intercept is the Y value when x = 0, which is -3.
The formula is y = 2/3x - 3
6. Point slope form is written as y - y1 = m(x- x1) where m is the slope, y1 and x1 are a known point on the line.
Slope = (1-0) / (1-3) = 1/-3 = -1/3
You can use either point shown for x1 and y1, so I am using the point (1,1)
The equation becomes y -1 = -1/3(x-1)

You pick a card at random, put it back, and then pick another card at random. 3 4 5 What is the probability of picking a number greater than 3 and then picking an even number?
Final answer:
To find the probability of drawing a four and then a five from a standard deck with replacement, multiply the probabilities of the independent events: (1/13) × (1/13) = 1/169.
Explanation:
The question involves calculating the probability of two independent events when drawing cards from a standard deck. The first event (A) is drawing a card that is a four, and the second event (B) is drawing a card that is a five. The probability of each of these events is calculated separately since the card is replaced after each draw, making the draws independent of each other.
The probability of drawing a four (P(A)) from a standard deck is 1/13, as there are four fours in a 52-card deck. Similarly, the probability of drawing a five (P(B)) is also 1/13. Since the events are independent, the combined probability is the product of the two probabilities: P(A) × P(B) = (1/13) × (1/13) = 1/169.

[tex]m=8[/tex]
But this isn't the final answer! You're supposed to find the angles' measures, which are [tex]2(3m+2)^\circ[/tex] and [tex](4m+20)^\circ[/tex] where [tex]m=8[/tex]. So the answer is [tex]2(3\cdot8+2)^\circ=\boxed{52^\circ}[/tex].
The inscribed angle is half that of the arc it comprises. The measure of both the angle is 52°.
How do we relate the inscribed angle and the arc?we know that the inscribed angle is half that of the arc it comprises.
Here, the arc that the inscribed angles comprise is the same.
2(3m+2)° = (4m+20)°
by solving for m
6m + 4 = 4m + 20
6m - 4m = 20 - 4
2m = 16
m = 8
To find the measure of the angle
(4m+20)°= 4(8) + 20 = 52°
2(3m+2)° = 2(26) = 52

Our basketball team has 10 players. we need to divide into two teams of 5 for an intra-squad scrimmage. in how many ways can we do this without restriction?
There are 252 ways to divide the 10 players into two teams of 5 without any restriction.
To determine the number of ways you can divide 10 players into two teams of 5 without any restriction,
Using the formula, C(n, k) = [tex]\frac{n!}{k!(n-k)!}[/tex]
By finding the number of ways to choose 5 players out of 10, which is the same as choosing the other 5 players who are not on the first team.
Where n = 10
k = 5
C(10, 5) = [tex]\frac{10!}{5!(10-5)!}[/tex]
C(10, 5) = [tex]\frac{10!}{5!(5)!}[/tex]
C(10, 5) = 10*9*8*7*6*5*4*3*2*1/5*4*3*2*1(5*4*3*2*1)
C(10, 5) = 30240/5*4*3*2*1
C(10, 5) = 252 ways
Therefore, there are 252 ways to divide the 10 players into two teams of 5 without any restriction.

Answer:
D. <F = 65 degrees
Step-by-step explanation:
First off, we know that the measures of <F and the angle adjacent to it add to 90 degrees, as indicated by the right angle. They are complementary angles.
The complementary angle of <F has an intercepted arc of 50 degrees. Because the angle is on the opposite end of the circle, it is half of the measure of the arc. Therefore, it is 25 degrees.
Because this angle and <F sum to 90, just subtract 90-25 to find <F.
<F = 65 degrees

At a certain time in the afternoon a light pole casts a shadow that us 11 ft 9 in long. At the same time, a woman of height 4 ft 6 in casts a shadow that is 18 inches long. How tall is the light pole?
We have similar triangles so
[tex]\dfrac{4'6"}{18"} = \dfrac{x}{11'9"}[/tex]
[tex] x= \dfrac{ (12(11)+9 )(12(4)+6) }{18 } = 423 \textrm{ inches}[/tex]
Answer: 35' 3"
To find the height of a light pole given the shadow lengths of the pole and a woman of known height, we use a proportion. The height of the light pole is calculated to be 35.25 feet based on the given information.
The question asks how tall a light pole is if the pole's shadow is 11 feet 9 inches, and a woman who is 4 feet 6 inches tall casts a shadow that is 18 inches long. This is a problem of proportional relationships between the heights of objects and the lengths of their shadows. Using the fact that the ratio of the height of an object to the length of its shadow is the same for all objects at a given time, we can set up a proportion:
Height of woman / Length of woman's shadow = Height of light pole / Length of light pole's shadow
(4.5 feet) / (1.5 feet) = Height of light pole / (11.75 feet)
Now, we can solve for the height of the light pole:
Height of light pole = (11.75 feet) * (4.5 feet) / (1.5 feet)
Height of light pole = (11.75 * 4.5) / 1.5 = (52.875) / 1.5 = 35.25 feet
So, the height of the light pole is 35.25 feet.

Suppose f(x)—>300 and g(x)—>0 with g(x)< 0 as x —>5. Determine lim x—>5 f(x)/g(x)
Given the conditions: f(x) approaches 300 and g(x) approaches 0 (and is less than zero as x approaches 5), the limit as x approaches 5 of the quotient f(x)/g(x) is negative infinity.
Explanation:Based on the given conditions: f(x) approaches 300 and g(x) approaches 0 as x approaches 5. Moreover, g(x) is less than zero, and therefore negative, as x approaches 5. When you divide f(x) by g(x), the sign of the outcome is determined by the signs of the numerator (f(x)) and the denominator (g(x)).
As f(x) is positive and g(x) is negative, the quotient will be negative. Since f(x) is approaching a finite value and g(x) is approaching 0, the quotient f(x)/g(x) tends toward negative infinity as per the properties of limits.
Therefore, the value of lim x→5 f(x)/g(x) is negative infinity.

Answer:
(x, y) = (-20, 7), (-5, -2), (0, 3), (15, -4), (30, 5)
Step-by-step explanation:
You want 1/5x to match the x-value in the given table. To make that happen, multiply the given x by 5.
Example: when (1/5x) = -4, f(1/5x) = 7, so x = -4·5 = -20 for y = 7.
The transformation f(1/5x) is a horizontal expansion by a factor of 5, so each point of f(x) is now 5 times farther from the y-axis than it was.

To complete the table for the function [tex]\(y = f\left(\frac{1}{5}x\right)\),[/tex] we need to substitute the given \(x\) values into the function [tex]\(y = f\left(\frac{1}{5}x\right)\)[/tex] and calculate the corresponding \(y\) values.
The function [tex]\(y = f\left(\frac{1}{5}x\right)\)[/tex]implies that we are scaling the input \(x\) by a factor of 5. This means the \(x\) values in the original table need to be multiplied by 5 to find the corresponding values for the new function. Let's calculate the values step by step:
1. For [tex]\(x = -4\):[/tex]
[tex]\[y = f\left(\frac{1}{5}(-4)\right) = f(-0.8)\][/tex]
Looking at the original table, when [tex]\(x = -0.8\), \(y = 3\).[/tex]
2. For [tex]\(x = -1\):[/tex]
[tex]\[y = f\left(\frac{1}{5}(-1)\right) = f(-0.2)\][/tex]
When [tex]\(x = -0.2\), \(y = -2\).[/tex]
3. For [tex]\(x = 0\):[/tex]
[tex]\[y = f\left(\frac{1}{5}(0)\right) = f(0)\][/tex]
When [tex]\(x = 0\), \(y = 3\).[/tex]
4. For [tex]\(x = 3\):[/tex]
[tex]\[y = f\left(\frac{1}{5}(3)\right) = f(0.6)\][/tex]
When [tex]\(x = 0.6\), \(y = 7\).[/tex]
5. For [tex]\(x = 6\):[/tex]
[tex]\[y = f\left(\frac{1}{5}(6)\right) = f(1.2)\][/tex]
When [tex]\(x = 1.2\), \(y = 5\).[/tex]

What else would need to be congruent to show that STU is congruent to JKL by SAS? tysm! :)
Answer:
Choice C.
Step-by-step explanation:
You already have two sides and two angles. Now you need the other two sides that include the angle. Choice C is correct.
Answer: C. [tex]\overline{SU}\cong\overline{JL}[/tex]
Step-by-step explanation:
SAS congruence postulate tells that if two sides and the included angle of a triangle are congruent to corresponding two sides and the included angle of other triangle, then the triangles are congruent.In the given picture , we have two triangles ΔSTU and Δ JKL , in which we have
[tex]\overline{ST}\cong\overline{JK}[/tex]
[tex]\angle{S}\cong\angle{J}[/tex]
To prove ΔSTU is congruent to Δ JKL, we need [tex]\overline{SU}\cong\overline{JL}[/tex] such that [tex]\angle{S}\text{ and }\angle{J}[/tex] becomes congruent the included angles between pair of congruent sides.
Hence, C is the right option.
