A circular mirror is surrounded by a square metal frame. The radius mirror is 6x the side length of the medal frame is 18x. What

wolverine [178]

Answer:

Step-by-step explanation:

Given:

Radius of circular mirror, r = 6x

Length of metal frame, l = 18x

Area of square, As = l^2

Area of square = 18x × 18x

= 324 x^2.

Area of circular mirror, Ac = pi × r^2

= π × (6x)^2

= 36π x^2.

The expression for the area of the frame is subtracting the mirror from the metal frame = As - Ac

= 324x^2 - 36πx^2

= 36x2 (9 - π).

What is the average rate of change of the function over the interval x = 0 to x = 8?

salantis [7]

Ans: The average rate of change of function = $\frac{1}{102}$ (in fraction)

Explanation:
The average rate of change of function = $\frac{f(b) - f(a)}{b - a}$

Where
b = 8 (x's upper bound)
a = 0 (x's lower bound)

$f(b) = f(8) = \frac{2*8-2}{5*8-6} = \frac{7}{17} \\ f(a) = f(0) = \frac{2*0-2}{5*0-6} = \frac{1}{3} \\ \frac{f(b) - f(a)}{b-a} = \frac{ \frac{7}{17} - \frac{1}{3}}{8} = \frac{1}{102}$

Hence the average rate of change of function = $\frac{1}{102}$ (in fraction)

Alex gets paid $2.25 a tree for tree planting up north. In one week, he planted 437 trees. What is his wage?

Amiraneli [1.4K]

Answer:

Hey Beebzie

Dang he part of 20m trees? And is Alex a he or she, we'll never know, so I'll just refer to Alex as "it" to not gender appropriate anyone.

So it gets paid 2.25 for one tree. It planted 437 tress.

We take 2.25 x 437 to know the amount of money earned for all trees it planted.

The answer is $983.25, or A. I don't want to gender appropriate the letter "A" either because it could be option 1 or a different letter so I'll just say the answer again to not be sexist, $983.25

Enter the domain and range of the function g(x) = 9x2 − 5 as an inequality, using set notation and using interval notation. Comp

tia_tia [17]

The domain and the range of a function are the set of input and output values, the function can take.

The domain and the range of $g(x) = 9x^2 - 2$ is $(-\infty, \infty)$ .
The parent function $f(x) =x^2$ is vertically compressed by 9, then shifted down by 5 units to get $g(x) = 9x^2 - 2$
