Don’t you just multiply it?
42 x 1.85 = 77.7
The student council will spend a total of $77.70 on balloons
X=4 is equivalent to -6+2x
<span>X+2a = 16+aX-6a
8X - 16 = aX-2a
8(X-2) = a(X-2)
</span><span>(X-2)/<span>(X-2)</span> = a/8
1 = a/8
a= 8

The period of oscillation of a pendulum is
![T=2 \pi \sqrt{ \frac{L}{g} }](https://tex.z-dn.net/?f=T%3D2%20%5Cpi%20%20%5Csqrt%7B%20%5Cfrac%7BL%7D%7Bg%7D%20%7D%20)
Where L is the length of the pendulum and
![g=9.81 m/s^2](https://tex.z-dn.net/?f=g%3D9.81%20m%2Fs%5E2)
the gravitational acceleration.
Re-arranging the formula and using T=1.0 s, we find the length of the pendulum:
The value of the composite function fog(1) is -1
Step-by-step explanation:
Step 1 :
Given,
f(-2) = -1
g(1) = -2
We need to find (fog)(1)
Step 2 :
Function f(2) means the value of the function f when x = 2
fog refers to composite function f(g(x)), that is evaluate the function g for x and then evaluate the function f for the result
So to find the composite function (fog)(1) we need to find g(1) first and then apply the function f on the result.
so g(1) = -2
f(g(1))=f(-2) = -1
fog(1) = -1
Step 3 :
Answer :
The value of the composite function is -1
