Answer:

x^2 + y^2 = 8^2

Step-by-step explanation:

The general equation in standard form here is x^2 + y^2 = r^2.

Replace r with 8, obtaining:

x^2 + y^2 = 8^2

The standard form equation of a circle with a radius of 8 and centered at the origin is x² + y² = 64.

The equation for a circle centered at the origin with a given radius can be written in standard form. For a circle with a radius of 8, which is centered at the origin, the standard form equation is x² + y² = 64. This equation is derived from the general formula for a circle's equation in standard form, which is (x - h)² + (em)(y - k)² = R², where (h, k) is the center of the circle and R is the radius. Since the center is at the origin, h and k both equal zero.

Bar graphs are easy to understand, widely used, and can show changes over time. That gives them an advantage over other graphs that are difficult to read or can only show a single data set.

They use vertical or horizontal bars to represent data along both an x-axis and a y-axis visually. Each bar represents one value, so it'll be an advantage for Peter because he can add as many colours he wants and the graph would still be easy to read. When the bars are stacked next to one another, the viewer can compare the different bars, or values, at a glance.

The opposites of the numbers 5, -2.5, 1.15, and 915 are -5, 2.5, -1.15 and -915 respectively. The opposite of a number is its value, but it is in the opposite direction on a number line.

The opposite of a number is the value that is exactly as far from 0, but in the opposite direction on a number line. Thus, the opposite of a positive number is the same number, but negative. Similarly, the opposite of a negative number is the same number, but positive. So the opposites of the given numbers 5, -2.5, 1.15, and 915 would be -5, 2.5, -1.15, and -915 respectively.

Answer:

[tex]g(x)=8(2^x)[/tex]

Step-by-step explanation:

Here we are given with parent function [tex]f(x)=2^x[/tex] and the graph which shows that the function g(x).

We are asked to guess the function g(x).

We are given the two coordinates on g(x)

(0,8) and (2,32)

Hence for x = 0 , g(x)= 8

And for x=2, g(x)= 32

Let us say that the translated function is represented by

[tex]g(x)=a2^x+b[/tex]

[tex]g(0)=a\times 2^0+b[/tex]

Hence

[tex]a \times 2^0+b=8[/tex]

[tex]a +b=8[/tex] --------------- (i)

also

[tex]g(2)=32[/tex]

Hence

[tex]a\times 2^2+b=32[/tex]

[tex]4a+b=32[/tex] -------------------(ii)

Subtracting (i) from (ii) we get

[tex]3a=34[/tex]

Hence a = 8

Now putting this value of a in (i)

[tex]8+b=8[/tex]

B=0

Hence [tex]g(x)=8 \times 2^x +0[/tex]

[tex]g(x)=8(2^x)[/tex]

Final answer:

To determine if a set of three lengths can be the side lengths of a triangle, we need to apply the triangle inequality theorem.

Explanation:

In order for a set of three lengths to be the side lengths of a triangle, they must satisfy the triangle inequality theorem. According to this theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side. This can be represented as:

a + b > c

a + c > b

b + c > a

For example, if the given lengths are 3, 4, and 7, we can check if they satisfy the inequality:

3 + 4 > 7

3 + 7 > 4

4 + 7 > 3

Since all of these inequalities are true, the lengths 3, 4, and 7 can indeed be the side lengths of a triangle.

Answer:

$126

Step-by-step explanation:

First, use the general percent equation (y is x% of z, y being your part percentage, x being your percent, and z being your whole base).

y = 40% x 90 --> .4 x 90 = 36

y = 36

Now, simply add the part percentage (36) to the original whole base.

90 + 36 = 126

The markup price of the model is equal to $126.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that a toy store's per cent of markup is 40%. A model train costs the store $90.

First, use the general per cent equation (y is x% of z, y being your part percentage, x being your per cent, and z being your whole base).

y = 40% x 90 --> .4 x 90 = 36

y = 36

Now, simply add the part percentage (36) to the original whole base.

90 + 36 = 126

The markup price of the model is $126.

Answer:

D. 914 feet

Step-by-step explanation:

We are given the distance that a person can see on a clear day from the upper observation platform of the Eiffel tower in Paris. We are then required to estimate the height of the upper observation platform using the formula;

[tex]d=\frac{5}{6}\sqrt{h}[/tex]

Where d is the distance and h the height of the upper observation platform. The first step would be to solve for h, that is make h the subject of the formula in the above equation;

We multiply both sides of the equation by the reciprocal of 5/6 which is 6/5;

[tex]\sqrt{h}=\frac{6}{5}d[/tex]

The next step is to eliminate the square root on the Left Hand Side of the equation by squaring both sides;

[tex]h=1.44d^{2}[/tex]

Given d is 25.2, h becomes;

[tex]h=1.44*25.2^{2}\\h=914.4576[/tex]

To the nearest whole number, h becomes 914

The correct option is D. The height of the upper observation platform is approximately 914 feet

To estimate the height  h  in feet of the upper observation platform using the given formula  [tex]d = \frac{5}{6} \sqrt{h}[/tex] , follow these steps:

1. Given:

d = 25.2 miles

We need to solve for  h .

2. Substitute the given  d  into the formula:

[tex]25.2 = \frac{5}{6} \sqrt{h}[/tex]

3. Isolate [tex]\sqrt{h}[/tex]:

Multiply both sides by [tex]\frac{6}{5}[/tex] to get rid of the fraction:

[tex]25.2 \times \frac{6}{5} = \sqrt{h}[/tex]

4. Calculate the left side:

[tex]25.2 \times \frac{6}{5} = 25.2 \times 1.2 = 30.24[/tex]

So,

[tex]\sqrt{h} = 30.24[/tex]

5. Square both sides to solve for  h :

[tex](\sqrt{h})^2 = 30.24^2 \\\\h = 30.24^2[/tex]

6. Calculate  30.24^2 :

[tex]30.24 \times 30.24 = 914.0576[/tex]

7. Round to the nearest whole number:

[tex]h \approx 914 \text{ feet}[/tex]

Therefore, the height of the upper observation platform is approximately 914 feet, which matches option D.

Answer: D. 914 feet

Final answer:

The probability that Mark spends a night at Rutgers University, the University of Miami, and Clemson University is 1/720, or approximately 0.00139.

Explanation:

To find the probability that Mark spends a night at Rutgers University, a night at the University of Miami, and a night at Clemson University, we assume that these choices are made without replacement from the 10 colleges he is considering. As he can only spend the night at 3 of them, his first choice has a 1 in 10 chance of being Rutgers University, his second choice a 1 in 9 chance of being the University of Miami, given that his first choice was Rutgers, and his third choice a 1 in 8 chance of being Clemson University, given that his first two choices were Rutgers and the University of Miami.

The overall probability is the product of these independent probabilities:

Probability = (1/10) × (1/9) × (1/8) = 1/720

Therefore, the probability is 1/720, or about 0.00139 when rounded to five decimal places.
