2nd answer
Answer:
Option B. -4x² - 11x + 13
Step-by-step explanation:
Given polynomials are ( -x² + 9 ) and ( -3x² - 11x + 4 )
We have to add them.
( -x² + 9 ) + -3x² - 11x + 4 )
-x² + 9 - 3x² - 11x + 4
Now we will collect similar terms
( -x² - 3x² ) - 11x + ( 9 + 4 )
-4x² - 11x + 13
Therefore, option B is the answer.

What is the average rate of change for this quadratic function for the interval from x=3 to x=4
ANSWER
A. 27.5
EXPLANATION
The average rate of change of the given quadratic function on the interval;
x=2 to x=4 is the slope of the secant line connecting the points (2,f(2)) and (4,f(4)).
This implies that the average rate of change is
[tex] = \frac{f(4) - f(2)}{4 - 2} [/tex]
From the table,
[tex]f(4) = 64[/tex]
and
f(2)=9.
The average rate of change becomes
[tex] = \frac{64 - 9} {4 - 2} [/tex]
[tex] = \frac{55}{2} = 27.5[/tex]
The correct choice is A.
If 2a+ 2/a =4, what is the value of 2a^2− 2/a^2 ?
ANSWER
0
EXPLANATION
Given :
[tex] \frac{2a + 2}{a} = 4[/tex]
We solve for 'a' to obtain,
[tex]2a + 2 = 4a[/tex]
This implies that,
[tex]2 = 4a - 2a[/tex]
[tex]2 = 2a[/tex]
This implies that,
[tex]a = 1[/tex]
We substitute a=1 into
[tex] \frac{ 2{a}^{2} - 2}{ {a}^{2} } [/tex]
This gives us,
[tex]\frac{ 2{(1)}^{2} - 2}{ {(1)}^{2} } = \frac{2 - 2}{2} = \frac{0}{2} = 0[/tex]

According to Casio Calculations the Answer is C.
You throw a stone from a height of 16 feet with an initial vertical velocity of 32 feet per second. the function h= -16t squared + 32t + 16 represents the h ( in feet) of the stone after t seconds) Find the Maximum height of the stone the maximum height. please help me somebody brainly teacher expert anyone please
hope this helps :)
Step-by-step explanation:
dh/dt=-32t+32
When velocity, dh/dt, is equal to zero, the object is at its maximum height.
dh/dt=0 only when 32t=32, t=1 second, so the maximum height is h(1)
h(1)=-16+32=16ft
Using algebra
The maximum height will occur at the midpoint between the two zeros of the height function because of a quadratics symmetry...
h(t)=0 when
-16t^2+32t=0
-16t(t-2)=0
so t=0 and 2
The midpoint is t=1
And of course this will give you the same as we found earlier. The maximum height is h(1) ft
Answer:
dh/dt=-32t+32When velocity, dh/dt, is equal to zero, the object is at its maximum height.dh/dt=0 only when 32t=32, t=1 second, so the maximum height is h(1)h(1)=-16+32=16ftUsing algebraThe maximum height will occur at the midpoint between the two zeros of the height function because of a quadratics symmetry...h(t)=0 when-16t^2+32t=0-16t(t-2)=0so t=0 and 2The midpoint is t=1

A rectangular prism has side lengths of 4 inches, 6 inches, and 7 inches. If all side lengths are doubled, what happens to the surface area
Original measurements:
L = 4; W = 6; H = 7
surface area = 2(LW + LH + HW)
surface area = 2(4 * 6 + 4 * 7 + 6 * 7)
surface area = 2(24 + 28 + 42)
surface area = 2(94)
surface area = 188
Doubled measurements:
L = 8; W = 12; H = 14
surface area = 2(LW + LH + HW)
surface area = 2(8 * 12 + 8 * 14 + 12 * 14)
surface area = 2(96 + 112 + 168)
surface area = 2(376)
surface area = 752
The surface area was 188 square inches and it became 752 square inches.
752/188 = 4
As the side lengths increased by a factor of 2, the surface area increased by a factor of 4.

Why is this expression not positive or negative when x=-5 -1.3x-6.5
Answer:
This is because this equation equals 0 when x = -5
Step-by-step explanation:
To find this, plug the value in for x.
-1.3x - 6.5
-1.3(-5) - 6.5
6.5 - 6.5
0
The expression -1.3x - 6.5 evaluated at x=-5 equals zero, which is why it is neither positive nor negative.
To verify this let's evaluate it step by step.
Substitute x = -5 into the expression:
-1.3(-5) - 6.5
Then, multiply -1.3 by -5:
-1.3 * (-5) = 6.5
Then, subtract 6.5:
6.5 - 6.5 = 0
The expression -1.3x - 6.5 evaluated at x=-5 equals zero, which is why it is neither positive nor negative.
How do you find interval of increase or decrease??
To find intervals of increase or decrease, analyze the function's derivative or slope. Linear regression uses a straight line equation to estimate these trends graphically. Graphs are helpful for visually representing increase or decrease rates and other numerical relationships.
To find intervals of increase or decrease in a function, you need to analyze the function's derivative. If the derivative is positive over an interval, the function is increasing; if the derivative is negative, the function is decreasing. An example of observing such behavior is through graphical analysis, where you look for portions of the graph that have an upward or downward slope, respectively.
Linear regression is a tool used to determine the rate of increase or decrease over a set of data points. By fitting a line X = S\u00d7t + I, where S is the slope and I the intercept with the vertical axis, one can estimate the trend or rate of change, assuming a linear relationship.
To describe the rate of growth in various contexts, such as population growth or economic data, graphs can display these trends visually. For different applications, such as contour mapping in geography, the interval of change might be adjusted to represent details accurately. A constant rate of growth assumption, however, isn't always correct and must be adjusted depending on the circumstances.

On a coordinate grid, the movie theater is located at (0,0) and the mall is located at (4,3). If the bowling alley is located at the midpoint between the theater and the mall, what is the approximate distance from the bowling alley to the mall? (Note: 1 unit equals 1 mile)
A) 1.3 miles
B) 1.5 miles
C) 2 miles
D) 2.5 miles
Answer:
D.) 2.5 miles
Step-by-step explanation:
The first step required for solving this problem is to calculate the midpoint between the theater and the mall (2, 1.5). Then use the distance formula to calculate the distance from the bowling alley to the mall.
The distance from the bowling alley to the mall is 2.5 miles. The coordinates of the midpoint, which is the location of the bowling alley, are calculated first. Then, using the Pythagorean theorem, the distance to the mall is found by calculating the square root of the sum of the squares of the horizontal and vertical distances.
Explanation:The task is to calculate the distance from the bowling alley to the mall if the bowling alley is at the midpoint between the movie theater at (0,0) and the mall at (4,3). First, we find the coordinates of the midpoint, which is the average of the x-coordinates and the y-coordinates of the two points respectively. Thus, the midpoint is located at:
(0 + 4) / 2 = 2 for the x-coordinate(0 + 3) / 2 = 1.5 for the y-coordinateSo, the bowling alley is at point (2, 1.5). Secondly, we use the Pythagorean theorem to find the distance from the bowling alley to the mall:
The change in x (horizontal distance) from the bowling alley to the mall is 4 - 2 = 2 units.The change in y (vertical distance) from the bowling alley to the mall is 3 - 1.5 = 1.5 units.Applying the distance formula (or Pythagorean theorem):
Distance = √( Δx² + Δy² ) = √( 2² + 1.5² ) = √( 4 + 2.25 ) = √6.25 = 2.5 miles
Therefore, the approximate distance from the bowling alley to the mall is 2.5 miles, which corresponds to answer (D).

The answer to your question is also attached in the images below
Answer:
x=2 ; x=-4 or x=-3/2
Step-by-step explanation:
We are given a cubic polynomial
[tex]2x^3+7x^2-10x-24=0[/tex]
Here as we are having a cubic equation to factorize, we have to find some value of x such that when we put that value in place of x , it gives us a 0. We have to try it randomly like first we try it for x=1 then x=2 and so on.
On trying for x=2 , we see that the equation becomes 0=0 and hence x=2 is one of the solution. And also as x=2 is one of the solution, (x-2) must be one of the factor. Now we use this property to determine the other factor like this.
[tex]2x^3+7x^2-10x-24=0[/tex]
Adding and subtracing [tex]4x^2[/tex] to [tex]2x^3[/tex] we get
[tex]2x^3-4x^2+4x^2+7x^2-10x-24=0[/tex]
Now we take out [tex]2x^2[/tex] as GCF
[tex]2x^2(x-2)+11x^2-10x-24=0[/tex]
Now subtracting and adding [tex]22x[/tex] to [tex]11x^2[/tex]
[tex]2x^2(x-2)+11x^2-22x+22x-10x-24=0[/tex]
taking [tex]11x^2[/tex] as GCF out
[tex]2x^2(x-2)+11x(x-2)+22x-10x-24=0[/tex]
[tex]2x^2(x-2)+11x(x-2)+12x-24=0[/tex]
[tex]2x^2(x-2)+11x(x-2)+12(x-2)=0[/tex]
Now taking [tex](x-2)[/tex] out as GCF
[tex](x-2)(2x^2+11x+12)[/tex]
Now we need to split the middle term of [tex](2x^2+11x+12)[/tex] to factorize it in such a way that their product is 2*12 and sum is 11. We have 8 and 3 as these factors.
Hence it can be factored like this
[tex](2x^2+11x+12)\\2x^2+8x+3x+12\\2x(x+4)+3(x+4)\\(2x+3)(x+4)[/tex]
Hence our answer will be
[tex](x-2)(2x+3)(x+4)=0[/tex]
And thus the solutions will be
x-2=0 : x=2
x+4=0 ; x=-4
2x+3=0 ; x=-[tex]\frac{3}{2}[/tex]

What is the probability of spinning a B?
Answer:
3/8 or 37.5%
Step-by-step explanation:
There are a total of 8 possible outcomes. B appears only 3 times in those 8 outcomes. Therefore, the chances of landing on B is 3 out of 8 or 3/8.
The probability of B in percent is 37.5 %.
What is Probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Here, Total outcomes = {A, A, B, B, B, C, C, C}
n(S) = 8
Now, possibility of B = {B, B, B}
n(B) = 3
Probability of B = Favorable outcomes/ total outcomes
= n(B) / n(S)
= 3/8
= 0.375
= 37.5 %
Thus, the probability of B in percent is 37.5 %.
