Answer:

7(3 + 3x) = 21x + 21

2d + 10(4d +4 + 2a) = 20a + 42d + 40

3t + 2x + x = 3t + 3x

5(r + 12) - 25 = 5r + 35

18s + 12rs + 10r - 2rs = 10rs + 10r + 18s

s(12 - 4) + 2 = 8s + 2

w(15 - 3) + 2 + 7w = 19w + 2

A piston is seated at the top of a cylindrical chamber with radius 3 cm when it starts moving into the chamber at a constant spe

dlinn [17]

Answer:

1. V = πr²h

2. dv/dt = πr²dh/dt

3. dv/dt = 113.04

Step-by-step explanation:

We have these information

Radius R = 3cm

Height = h

Volume = V

We have been given dh/dt = 4cm

An equation relating V, r, h

Volume of cylinder = πr²h

The related rates equation

dv/dt = πr²dh/dt

dv/dt = π3²dh/dt

3. Continuing from number 2 above, we have

dv/dt = π3²dh/dt

= π9x4

= 3.14x9x4

= 113.04

These are the answers to the questions

Find the equation of the linear function represented by the table below in slope-

pav-90 [236]

Answer: $y=-3x-2$

Step-by-step explanation:

Using the values $x=-2, y=4$ and $x=1, y=-5$ , the slope is $\frac{-5-4}{1-(-2)}=-3$ .

So, the equation is:

$y-4=-3(x+2)\\\\y-4=-3x-6\\\\y=-3x-2$
