what is the greatest number of obtuse angles that a right triangle can contain
A) 3
B) 1
C) 0
D) 2

Answers

Answer:0

Step-by-step explanation:

A right triangle can have at most one obtuse angle since it already contains one right angle, and the sum of its angles must be 180 degrees according to geometrical axioms.

The question asks about the maximum number of obtuse angles that can be contained in a right triangle. In a right triangle, one angle is 90 degrees by definition, which is a right angle. According to Theorem 20, the sum of the angles of a triangle is two right angles, which equals 180 degrees. Having an obtuse angle, which is greater than 90 degrees, combined with a 90 degree angle, would exceed 180 degrees when the third angle is added, and this is not possible in a plane geometric figure. Therefore, a right triangle cannot have more than one right angle. As such, the option with the maximum number of obtuse angles a right triangle can contain is:

The diagonal of the rectangle is 13 inches, and the side lengths of the triangles are Pythagorean triples. To the nearest tenth, what is the area of the shaded part of the figure?

Answers

1) A Pythagorean triples is a set of three integers, a, b, c,  that follow the rule a^2 + b^2 = c^2

2) Assumin c is the diagonal of your rectangle and the hypotenuse of the triangles, you are looking this:

13^2 = a^2 + b^2

=> 169 = a^2 + b^2

Two integer numbers that meet that equality are 5 and 12:

5^2 = 25
12^2 = 144
=> 5^2 + 12^2 = 25 + 144 = 169

 => 13^2 = 5^2 + 12^2

Now that you have the three numbers you know the dimensions of the figure and can calculate the area of the shaded part. I cannot do that for you becasue you did not include the figure.

The answer would be B, incenter.


Hope I could help. 

Answer:

The correct answer to the following question will be Option B (Incenter).

Step-by-step explanation:

The middle of the circle which is carved in a triangle is the triangle incenter, the point where the triangle angle bisectors cross.

There are following steps to construct an inscribed circle in a triangle are as follows:

Step 1: Create the incenter.

Step 2: Construct a line that passes through incenter, perpendicular to one side of the triangle. The segment which connects the incenter with the triangle intersection point and the perpendicular line is the circle radius.

Step 3: Build a centered circle at the incenter with radius spotted in step 2.

Graph the following piecewise function and then find the range.

Answers

The same function as in the one of other your questions.

[tex]D:[1,109)[/tex]

Answer:

The correct option is 3.

Step-by-step explanation:

The given piecewise function is

[tex]f(x)=\begin{cases}3x^2+1 & \text{ if } -4<x<6 \\ 6 & \text{ if } 6\leq x<9 \end{cases}[/tex]

Range is the set of output or y values.

The given function for 6 ≤ x < 9 is

[tex]f(x)=6[/tex]

It is a constant function, the value of function is 6 for all values of x.

Range = 6

The given function for -4 < x < 6 is

[tex]f(x)=3x^2+1[/tex]          .... (1)

It is a quadratic function.

The vertex form of a quadratic function is

[tex]f(x)=a(x-h)^2+k[/tex]         ....(2)

Where (h,k) is vertex and a is constant.

From (1) and (2), we get a=3,h=0,k=1.

The vertex of this function is (0,1), it means the range of this function is greater than or equal to 1. But this function is only defined for -4 < x < 6.

[tex]f(-4)=3(-4)^2+1=49[/tex]

[tex]f(6)=3(6)^2+1=109[/tex]

The maximum value of the maximum value of the function is 109 at x=6. Since 6 is not included in the interval -4 < x < 6, therefore 109 is not included in the range.

Range = [1,109)

When we combined the range of both functions we get

Range = [1,109)

Therefore the correct option is 3.

what is a transformation that proportionally reduces or enlarges a figure.

Answers

Answer: Dilation is a transformation that proportionally reduces or enlarges a figure.

Step-by-step explanation:

A dilation a transformation that changes the size of the shape by using scale factor in particular ways .

It stretches or shrinks the actual figure. It produces similar figures.

Since the corresponding sides of similar figures are in proportion.

It proportionally reduces or enlarges a figure.

Hence, A dilation is a transformation that proportionally reduces or enlarges a figure.

Final answer:

A scale transformation or dilation is a linear transformation that proportionally enlarges or reduces a figure, maintaining the proportional size relationships within the figure.

Explanation:

A transformation that proportionally reduces or enlarges a figure is known as a scale transformation or dilation. In such a transformation, lines are transformed into lines, and parallel lines remain parallel, consistent with the requirement for a transformation to be linear. This is important because it maintains the proportionality of the figure, meaning the size relationship of the parts of a figure to each other and to the whole figure remains constant, even though the overall size changes. Dilation can be characterized by a scale factor, which dictates how much larger or smaller the figure will become. If the scale factor is greater than 1, the figure enlarges; if it is between 0 and 1, the figure reduces in size.

The price y is a function of x, the speed of the processor.

In function notation this means, y=f(x), where f(x)=101x + 207.85.

For example to calculate the (approximate) price of a laptop with processor 4 gigahertz, we let x=4, and plug in f. 

That is the price y for x=4 is calculated by y=f(4).

So, since y=f(x)=101x + 207.85, the (expected) price of a laptop with processor speed 2.5 gigahertz is :

y=f(2.5)=101(2.5)+207.85= 460.35 ($)

You need to have a password with 55 letters followed by 33 odd digits between 00 and 99, inclusive. if the characters and digits cannot be used more than once, how many choices do you have for your password?

Answers

Mahtematical and statistical reasoning makes it evident that there is a mistake in the writing of the question and the digits were duplicated. So the right question is:

"You need to have a password with 5 letters followed by 3 odd digits between 0 and 9, inclusive. If the characters and digits cannot be used more than once, how many choices do you have for your passwor?"

The solution is:

5 letters from 26 with no repetition => 26*25*24*23*22 different choices.

odd digits are 1, 3, 5, 7 and 9 => 5 different digits to choose

3 digits from 5 with no repetition => 5*4*3 = 60

Then, the total number of choices is: 26*25*24*23*22*60 = 473,616,000

Answer: 473,616,000 choices.

What, roughly, is the percent uncertainty in the volume of a spherical beach ball whose radius is r = 2.86 plus or minus .09 m?

Answers

The volume of a sphere is calculated through the equation,
  
       V = 4πr³ /3
where r is the radius of the given. 

If the radius is 2.86, we can substitute the value to the equation above such that,
         V = 4π(2.86)³ / 3 = 97.99π m³

When the radius is 0.09 m plus the given radius then,
       V = 4π(2.86 - 0.09)³ / 3 = 89.03π m³

The difference between the volumes is equal to,
       difference = 97.99π - 89.03π m³ = 8.96π m³

Dividing this to the original volume and multiplying by 100%,
    percentage = (8.96π/97.99π) x 100% 
    percentage = 9.14%.

Hence, the expected percent uncertainty is equal to 9.14%. 

Final answer:

To calculate the percent uncertainty in the volume of a spherical beach ball when the radius is uncertain, you multiply the square of the radius by four (surface area), by the uncertainty in the radius, and then compare this value to the total volume. The percent uncertainty is found to be approximately 2.62%.

Explanation:

To determine the percent uncertainty in the volume of a spherical beach ball with a radius of 2.86 1 0.09 meters, one must first calculate the volume's uncertainty, then relate this to the total volume, and finally convert this relationship into a percentage.

The formula for the volume of a sphere is [tex]V = (4/3)\pi(r^3)[/tex]. Since volume is proportional to the cube of the radius, any uncertainty in the radius dramatically affects the volume uncertainty. Using a function for the volume V(r) and applying the approximation for small changes in r, we have:

[tex]V = (4/3)\pi(r^2))(r)[/tex]

For a radius of 2.86 meters and an uncertainty of 0.09 meters, the uncertainty V in volume is 170 [tex]cm^3[/tex]. The volume is approximately V = [tex](4/3)(3.14)(2.86^3)[/tex] = 6538 [tex]cm^3[/tex]. Therefore, the volume expressed with its uncertainty is [tex]6500 \pm170[/tex] [tex]cm^3,[/tex] rounded to avoid false precision.

To find the percent uncertainty:

Convert the uncertainty to the same units as the ball's volume if needed (here both are in cm^3).

Divide the uncertainty by the volume: (170/6500) x 100%.

The percent uncertainty is approximately 2.62%.

An object is dropped from a height of 1,600 feet. The amount of time, in seconds, the object takes to hit the ground can be found by solving the equation −16t2+1,600=0. How many seconds will it take to hit the ground?

Answers

As it is stated in this item, in order to determine the amount of time it takes to hit the ground, the equation 
                           -16t² + 1600 = 0

Transpose the terms without variable to the other side of the equation,
                             -16t² = -1600

Divide the equation by -16.
                               t² = 100

Solve the value of t by getting the square root of the equation.
                               t = +/- 10

Thus, it will take the object 10 seconds to reach the ground. 
Final answer:

To find the time it takes for the object to hit the ground, we can solve the quadratic equation -16t^2 + 1600 = 0 using the quadratic formula. The positive solution to this equation gives us the time in seconds. Therefore, the object will take √102400/32 seconds to hit the ground.

Explanation:

To find the time it takes for the object to hit the ground, we need to solve the equation -16t^2 + 1600 = 0. This is a quadratic equation, so we can use the quadratic formula. Plugging in the values, we get t = (-b ± √(b^2 - 4ac))/(2a). In this case, a = -16, b = 0, and c = 1600. Plugging in these values, we get t = (± √(0 - 4(-16)(1600)))/(2(-16)). Simplifying the equation further, we get t = (± √(0 + 102400))/(32). This gives us two possible values for t: t = √102400/32 and t = -√102400/32. Since time cannot be negative in this context, we can discard the negative solution. Therefore, the object will take √102400/32 seconds to hit the ground.

For the function h defined by h(x)=2x2−2, find h(−12)

Answers

Final answer:

To find h(-12), substitute -12 into the function h(x)=2x²-2. The value of h(-12) is 286.

Explanation:

To find h(-12), we substitute -12 into the function h(x)=2x²-2:

h(-12) = 2(-12)² - 2

h(-12) = 2(144) - 2

h(-12) = 288 - 2

h(-12) = 286

Therefore, h(-12) is equal to 286.

The area of the rectangle is:

[tex]Area_{Rectangle}=a*b[/tex]

where:

[tex]a=4ft\\b=2\frac{1}{2}ft[/tex]

we replace values(we convert the mixed fraction to improper fraction by multiplying the whole number part by the fraction's denominator, then add that to the numerator  then write the result on top of the denominator.):

[tex]Area_{Rectangle}=4*2\frac{1}{2} =4*\frac{5}{2}=10[/tex]

The area of the ellipse is:

[tex]Area_{Ellipse}=a*b*\pi[/tex]

where:

[tex]a=Radius1=1\frac{1}{4}ft\\b=Radius2=2ft\\[/tex]

Radius2 will be half the side of the rectangle

[tex]Radius2=\frac{4}{2}=2[/tex]

we replace the values:

[tex]Area_{Ellipse}=1\frac{1}{4} *2*\pi=\frac{5}{4}*2*\pi=\frac{5}{2}\pi =7.85[/tex]

we calculate now the total area:

[tex]Area =Area_{rectangle}+\frac{1}{2} Area_{Ellipse}\\Area=10+\frac{1}{2}(7.85)=10+3.93=13.93ft^{2}[/tex]

What is the probability that the person's skin cleared up given that they used the medication?

Answers

Answer: 3/5 is the probability that person's skin cleared up given that they used the medication.

Step-by-step explanation:

let S represents skin cleared and M represents medicine used.

According to the given Venn diagram,

P(S) = 40

P(M)= 50

[tex]P(M\cap S) = 30[/tex]

Thus by the definition of conditional probability,

If it is given that the skin is cleared then the probability that persons used the medicine,

P(M/S)=[tex]\frac{P(M\cap S)}{P(S)}[/tex]=30/50= 3/5.

P(M/S)=3/5.


The probability that the person's skin will clear up given that they used the medication is:

3/5

What is Probability?

This refers to the likelihood of an event to occur based on certain conditions.

If we want to find the probability about whether the skin will clear up is:

We would assign S to represent the skin

M to represent medicine

Hence,

P(S) = 40P(M)= 50

P(MnS) = 30

Using the conditional probability rule,

P9M/S)= P(MnS)/P(S) = 30/50

Two parabolas are the graphs of the equations $y=2x^2-10x-10$ and $y=x^2-4x+6$. give all points where they intersect. list the points in order of increasing $x$-coordinate, separated by semicolons.

Answers

(-2,18):(8,38) Set them equal to each other you get, x^2-6x-16=0, you can factor to get, (x-8)(x+2) to get solutions 8,2 for the x values then plug in for y values.

Answer:

(-2, 18) and (8, 38)

Step-by-step explanation:

First, set the two equations equal to each other to get $2x^2-10x-10=x^2-4x+6$. Combine like terms to get $x^2-6x=16$. To complete the square, we need to add $\left(\dfrac{6}{2}\right)^2=9$ to both sides, giving $(x-3)^2=16+9=25$.

So we have $x-3=\pm5$. Solving for $x$ gives us $x=-2$ or $8$. Using these in our original parabolas, we find the points of intersection to be $\boxed{(-2,18)}$ and $\boxed{(8,38)}$.
