Answer:
-3
Step-by-step explanation:
f(x)=2x+1
f(-2)=2(-2)+1=-4+1=-3
Answer:
187 ft/s
Step-by-step explanation:
Given in the y direction:
v₀ = 0 ft/s
Δy = 75 ft
a = 32 ft/s²
Find: t
Δy = v₀ t + ½ at²
(75 ft) = (0 ft/s) t + ½ (32 ft/s²) t²
t = 2.165 s
Given in the x direction:
Δx = 480 ft
a = 0 ft/s²
t = 2.165 s
Find: v₀
Δx = v₀ t + ½ at²
(480 ft) = v₀ (2.165 s) + ½ (32 ft/s²) (2.165 s)²
v₀ = 187 ft/s
Answer:

Step-by-step explanation:
So we have the equation:

And we want to solve for R.
First, let's multiply both sides by J to remove the fraction on the right. So:

Simplify the right:

We can rewrite our equation as:

So, to isolate the R variable, divide both sides by I²t:

The right side cancels, so:

And we are done!
Answer:
<em>h = v/lw .</em>
Step-by-step explanation:
v=lwh
Divide both sides by lw:
v / lw = h.
