Answer:
−8n−2
Step-by-step explanation:
g(f(n))
g(-4n-1)= 2(-4n-1) +5-----> −8n+3
Answer:
dA/dt = 169,56 in²/min
Step-by-step explanation:
We have a circular puddle and its area is:
A = π*r² (1) r is the radius of the circular puddle
Differentiating on both sides of the equation we get:
dA/dt = π*2*r*dr/dt (1)
In that expression we know
r = 9 inches and dr/dt = 3 in/min. Therefore plugging these values in equation (1)
dA/dt = π*2*9*3
dA/dt = 169,56 in²/min
First, you would subtract 1,800,000 and 40,000 to find the difference. Divide the difference by 40,000, then multiply by 100.
<span>The form of a linear equation that shows the slope and one point is the POINT-SLOPE FORM.
</span>Equations in point-slope form<span> look like this: y - k = m(x - h) where m is the </span>slope<span> of the line and (h, k) is a </span>point<span> on the line (any </span>point<span> works). To write an equation in </span>point-slope form<span>, given a graph of that equation, first determine the </span>slope<span>by picking two </span>points<span>.
