Answer:

178.98 ft2

Step-by-step explanation:

we know that

The area of the circular path alone is equal to subtract the area of the circular garden from the area of the complete circle (circular garden plus circular path)

so

A=\pi (r_2^2-r_1^2)

where

r_1=8\ ft ---> radius of circular garden

r_2=8+3=11\ ft ----> radius of the circular garden plus radius circular path

substitute

A=3.14 (11^2-8^2)=178.98\ ft^2

(100 Points) Given f of x is equal to 10 divided by the quantity x squared minus 7x minus 30, which of the following is true?
ikadub [295]

Answer:

f(x) is positive for all x > 10

Step-by-step explanation:

Given function:

f(x)=\dfrac{10}{x^2-7x-30}

<u>Asymptote</u>

Asymptote: a line which the curve gets infinitely close to, but never touches.

Factor the denominator of the function to find the vertical asymptotes:

\implies x^2-7x-30

\implies x^2-10x+3x-30

\implies x(x-10)+3(x-10)

\implies (x+3)(x-10)

Therefore:

f(x)=\dfrac{10}{(x+3)(x-10)}

The function is undefined when the denominator is equal to zero.

Therefore, there are vertical asymptotes at x = -3  and  x = 10
and a horizontal asymptote at y = 0

f(x) is positive for (10, ∞)

f(x) is negative for (-3, 10)

f(x) is positive for (-∞, -3)

For each exponential function, a) write a new function, and b) sketch the corresponding graph (on the same coordinate plane) bas
Luda [366]

A reflection over the y-axis means that "x" will change signs.

A dilation causes the graph to stretch (if the factor is greater than 1) or shrink/compress (if the factor is between 0 and 1). Usually, the instructions will say whether it is a vertical or horizontal stretch (or shrink) so you know which variable is affected. Since it was not specified, I am going to assume that this is both a vertical and a horizontal shrink.

Answer: y = \frac{1}{2}(4^{-2x})

Which triangles can have two sides of the same lenghth
alisha [4.7K]

An isosceles triangle is a triangle with 2 congruent sides. The congruent sides are called legs and the third side is called the base. So if 2 sides of a triangle have the same length, then we say that the triangle is isosceles.
