The area of the circle is the amount of space it occupies, and the area of the circle is 156.25π

The circumference, C is given as:

C = 25π

Start by calculating the radius using:

C = 2πr

So, we have:

2πr = 25π

Solve for r

r = 12.5

The area is then calculated using:

A = πr²

So, we have:

A = π * 12.5²

Evaluate

A = 156.25π

Hence, the area of the circle is 156.25π

The x-intercept of the graphed function is (-1,0)

The x-intercept of the graphed function is the point where the function has a value of 0

i.e. the x value when y = 0

From the complete question, we have:

x = -1 when y = 0

Using the z-distribution, it is found that the desired measures are given as follows:

At the null hypotheses, it is tested if the mean is of 61.5, that is:

[tex]H_0: \mu = 61.5[/tex]

At the alternative hypotheses, it is tested if the mean is less than 61.5, that is:

[tex]H_1: \mu < 61.5[/tex]

The test statistic is given by:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

The parameters are:

The values of the parameters are given as follows:

[tex]\overline{x} = 59.1, \mu = 61.5, \sigma = 17.6, n = 34[/tex]

Hence, the test statistic is given by:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{59.1 - 61.5}{\frac{17.6}{\sqrt{34}}}[/tex]

z = -0.795.

We have a left-tailed test, as we are testing if the mean is less than a value, with z = -0.795. Hence, using a z-distribution calculator, the p-value is of 0.2133.

Answer:

[tex]\textsf{b)} \quad y=2(x-4)^2-2[/tex]

Step-by-step explanation:

Vertex form of a parabola:  [tex]y=a(x-h)^2+k[/tex]

(where (h, k) is the vertex and [tex]a[/tex] is some constant)

Substitute the vertex into the formula:

[tex]\begin{aligned}\implies y &=a(x-(-1))^2-4\\y & =a(x+1)^2-4\end{aligned}[/tex]

Substitute the point (1, 0) into the formula:

[tex]\begin{aligned}\implies a(1+1)^2-4&=0\\4a-4&=0\\4a &=4\\a &=1\end{aligned}[/tex]

Therefore, the equation of the parabola in vertex form is:

[tex]y=(x+1)^2-4[/tex]

Substitute the vertex into the formula:

[tex]\begin{aligned}\implies y &=a(x-4)^2+(-2)\\y & =a(x-4)^2-2\end{aligned}[/tex]

Substitute the point (6, 6) into the formula:

[tex]\begin{aligned}\implies a(6-4)^2-2&=6\\4a-2 & =6\\4a &=8\\a &=2\end{aligned}[/tex]

Therefore, the equation of the parabola in vertex form is:

[tex]y=2(x-4)^2-2[/tex]

Answer:

- for the number line check out the attached photo

- 7

Step-by-step explanation:

- on the number line, each small mark represents 1/6 so to make it easier I made the fraction into 1/6 form

- a coefficent is a numerical value placed before and multiplying the variable in an algebraic expression (ex. 4x)

In this case 7 is before the m making 7 the coefficent

Answer: 25cm

Step-by-step explanation:

Since the field is square we can understand each side is an equal length

This means we just have to use the formula...  

[tex]A^2 = 625[/tex]

[tex]\sqrt{a^2} = \sqrt{625}[/tex]

a = ±25

Since it is a real thing, we are only looking at positive values, therefore your answer is

Step-by-step explanation:

in its basic structure such a prism is like a cube (just rectangular and not squared) : 6 sides (rectangles).

2 rectangles top and bottom 6×8 = 48 m²

48 × 2 = 96 m²

2 rectangles front and back 6×4 = 24 m²

24 × 2 = 48 m²

2 rectangles left and right 8×4 = 32 m²

32 × 2 = 64 m²

the total surface area is

96 + 48 + 64 = 208 m²

it is hard to find other integer dimensions for the same surface area.

but as long as we are not restricted to integer numbers :

let's cut e.g. the height in half.

and we get

2 rectangles left and right 8×2 = 16 m²

16 × 2 = 32 m²

that "nails" already 2 dimensions (width and height).

we need to set now the third dimension (length) to create the same surface area :

length×8×2 + length×2×2 = 208 - 32 = 176

20×length = 176

length = 8.8 m

so, with

length = 8.8 m

width = 8 m

height = 2 m

we still get

2 rectangles top and bottom 8.8×8 = 70.4 m²

70.4 × 2 = 140.8 m²

2 rectangles front and back 8.8×2 = 17.6 m²

17.6 × 2 = 35.2 m²

2 rectangles left and right 8×2 = 16 m²

16 × 2 = 32 m²

as total surface area

140.8 + 35.2 + 32 = 208 m²
