Answer:
1. f(-2) = -7
2.f(7) = 11
3. f(-4) = -11
Step-by-step explanation:
1. substitute x = -2 in f(x)
The function becomes :
f(-2) = 2×(-2) - 3 = -7
2. substitute x = 7 in f(x)
the function becomes:
f(7)= 2×7 - 3 = 11

Step-by-step explanation:
For a loaded spring, the frequency of oscillation is given by
where 
Vis the mass of the load and 
is spring constant.
Substituting values in the question,
This value is in units of oscillations per second. To convert to oscillations per minute, we divide by 
or, in essence, multiply 
by 60.
Thus, we have
Answer:
206.6 unit^2 to the nearest tenth.
Step-by-step explanation:
We use the formula Area= 1/2 ab sin A
= 1/2 + 19 * 24 sin 65
206.64 unit^2.
