QUESTION 9

Mars2501 [29]

Answer:

x = 31

Step-by-step explanation:

Given:

f(x) =

$2 {x}^{2} - 1$

g(x) = x + 2

We will first find g(2).

g(2) = 2 + 2 = 4

Next we will find f(g(2)).

f(g(2))= f(4) =

$2( {4}^{2} ) - 1 \\ = 2(16) - 1 \\ = 32 - 1 \\ = 31$

each leg =2
while the base =4
To find the number you have to divide the ratio by total and multiply into 105
The base
3/7 × 105 = 45
The leg
2/7 × 105 = 30
Therefore, The length of the base = 45 cm

Find the circumference of a circular field with a diameter of 16 yards.<br> (Let it = 3.14)

Tatiana [17]

Answer:

Hey there!

The circumference of a circle is $\pi(d)$ , where d is the diameter, and $\\\pi$ is a constant roughly equal to 3.14.

The diameter is 16, so plugging this into the equation, we get 3.14(16)=50.24.

The circumference of the circle is 50.24 yards.

Hope this helps :)
