Let 
x = measure of angle TAP
y = measure of angle BRE

We're told that "angle BRE is its own complement" meaning that angle BRE added to itself is 90 degrees. In algebraic terms, we can say

y+y = 90
2y = 90
2y/2 = 90/2
y = 45

So angle BRE is 45 degrees. Note how 45+45 = 90. 

We also know that angle TAP and angle BRE are supplementary. They add up to 180 degrees

x+y = 180
x+45 = 180 ... replace y with 45
x+45-45 = 180-45 ... subtract 45 from both sides
x = 135

Since we defined x to be the measure of angle TAP, this means that angle TAP is 135 degrees

Which one of the following statements is true? (5 points)
DanielleElmas [232]

Answer:

  None of these statements are true.

Step-by-step explanation:

a) The derivative of (fg)(x) is f'g +fg' according to the product rule for derivatives.

__

b) The derivative of |x² +x| is a 3-part piecewise linear function equal to 2x+1 for |x+1/2| > 1/2, and equal to -2x-1 for |x+1/2| < 1/2. It is undefined for x=0 and x=1.

__

c) for y = √f(x), y' = f'(x)/(2√f(x))

A tree in John's backyard has been growing for 4 1/2 years. The tree is 4/5 meters tall. What is the unit rate in meters per yea
STatiana [176]

Answer:

<u>5 127/200 meters</u>

Step-by-step explanation:

4 1/2 = 4 5/10 | 4/5 = 8/10

--------------------------------------

4 5/10 = 4.5 | 8/10 = 0.8

--------------------------------------

4.8 divided by 0.8 = 5.625

--------------------------------------

5.635 = 5 635/1000

635/1000 divided by 5 = 127/200

--------------------------------------

5 + 127/200 = <u>5 127/200</u>

First factor (x square -36), the answer will be (x+6)(x-6).

Second, cancel the x .

6x/ (x+6)(x-6)

4x/(6)(-6)

4x/-36
