Answer:

C) $4a^{6}b$

Step-by-step explanation:

$\frac{(4b^{3} 3a^{4}b^{2})}{3a^{-2} b^{4}}$ Copy the original equation

$\frac{12a^{6}b^{5}}{3b^{4} }$ Combine like terms

$\frac{12a^{6}b}{3}$ Simplify the b, then divide by 3

$4a^{6}b$

Match each slope and y-intercept with the appropriate linear equation.

Bumek [7]

Answer:

m= 4, b = 3 matches with y = 4x +3

m=5, b = -2 matches with y = 5x - 2

m = 3, b = 4 matches with y = 3x + 4

m = -2, b=5 matches with y = -2x + 5

Step-by-step explanation:

Slope-intercept form is y = mx + b in which m = slope and b = y-intercept

if the velocity of a body changes from 13m/s to 30m/s while undergoing constant acceleration whats the average velocity of the b

34kurt

Average speed = (1/2) (beginning speed + ending speed)
= (1/2) ( 13 m/s + 30 m/s )
= (1/2) ( 43 m/s )
= 21.5 m/s

Answer:

about 81 years

Step-by-step explanation:

A graphing calculator can give you the answer easily.

You can solve the problem algebraically by putting in the given number and solving for t.

30000 = 32000/(1 +12.8e^(-.065t))

12.8e^(-.065t) = (32000/30000) -1 = 1/15

e^(-.065t) = 1/(15·12.8) = 1/192 . . . . . divide by 12.8

-0.065t = ln(1/192) ≈ -5.257 . . . . . . take the natural log

t = -5.257/-0.065 ≈ 80.88 . . . . . . . .divide by the coefficient of t

It will take about 81 years for the number of trees to reach 30,000.
