When Grayson moved into a new house, he planted two trees in his backyard. At the time of planting, Tree A was 29 inches tall an

d Tree B was 14 inches tall. Each year thereafter, Tree A grew by 2 inches per year and Tree B grew by 5 inches per year. Let A A represent the height of Tree A t t years after being planted and let B B represent the height of Tree B t t years after being planted. Write an equation for each situation, in terms of t , t, and determine the height of both trees at the time when they have an equal height.

Tree A. Tree B
==
|. =
|. - 29in. |. = 14 in
|. |


year one:
tree A-29+2=31
tree B- 14+5= 19


year two
Tree A- 31+2=33
Tree B- 19+5= 25


and this continues until the same height is reached

find the local and/or absolute extrema for the function over the specified domain. (Order your answers from smallest to largest
Arlecino [84]

Answer:

Minimum 8 at x=0, Maximum value: 24 at x=4

Step-by-step explanation:

Retrieving data from the original question:

f(x)=x^{2}+8\:over\:[-1,4]

1) Calculating the first derivative

f'(x)=2x

2) Now, let's work to find the critical points

Set this

2x=0\\x=0    

0, belongs to the interval. Plug it in the original function

f(0)=(0)^2+8\\f(0)=8

3)  Making a table x, f(x) then compare

x|  f(x)

-1 | f(-1)=9  

0 | f(0)=8   Minimum

4 | f(4)=24 Maximum

4) The absolute maximum value is 24 at x=4 and the absolute minimum value is 8 at x=0.

write an equation in point-slope form for the line through the given point with the given slope (10,-9);m=-2​
fgiga [73]

Answer:

The answer is

<h2>y + 9 =  - 2(x - 10)</h2>

Step-by-step explanation:

To find the equation of a line given a point and slope we use the formula

<h3>y - y1 = m(x - x1)</h3>

where

m is the slope

( x1 , y1) is the point

From the question

Slope / m = - 2

The point is ( 10, - 9)

Substitute the values into the above formula

That's the final answer is

<h3>y + 9 =  - 2(x - 10)</h3>

Hope this helps you
