Answer:

Radius: 7

Diameter: 14

Area Formula: π r^2

Area Answer: 154 ft^2

Step-by-step explanation:

Radius: 14/2 = 7

The radius is always half the diameter.

Area Work

A = π(7)^2

A = π(49)

A = 153.9380 ft^2

How many solutions does the system have? \begin{cases} 5y =15x-40 \\\\ y = 3x-8 \end{cases} ⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ 5y=15x−40 y=3x−8 C

Ksenya-84 [330]

Answer:

Step-by-step explanation:

Converting the lines into the from $ax+by+c=0$

$5y=15x-40\\\Rightarrow 15x-5y-40=0$

$y=3x-8\\\Rightarrow 3x-y-8=0$

$\dfrac{a_1}{a_2}=\dfrac{15}{3}=5$

$\dfrac{b_1}{b_2}=\dfrac{-5}{-1}=5$

$\dfrac{c_1}{c_2}=\dfrac{-40}{-8}=5$

So, $\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}$ .

Hence, these lines have infinitely many solutions.

Find the interval(s) on which the function is increasing.

Tatiana [17]

Answer:

II (THE Second one )

Step-by-step explanation:

Because when you substitute X by (-2)

you will get :

y=(-2)^2 - 6(-2) - 16 = Zero

So, -2 is not including in the interval .
