Answer:
21; the age of the teacher
Step-by-step explanation:
15+x/2=18
Estimate - I estimated in the 20's because it only averaged up a little bit
Started with 23 and kept going until i got to my answer
21
15+21/2
36/2
18
Please mark brainliest :)
The answer is B.
f(x)= cos(x-90) = -cos(90-x)
(If you know how to, draw the CAST chart)
-cos(90-x)= -sin(x)
Sub. x=0, -sin(0)= 0
Answer:
$88

Simple Interest Rate Formula: A = P(1 + rt)
- <em>P</em> is principle amount
- <em>r</em> is rate
- <em>t</em> is time
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
<em>P</em> = 80
<em>r</em> = 2% = 0.02
<em>t</em> = 5
<u>Step 2: Find Interest</u>
- Substitute in variables [Simple Interest Rate Formula]: A = 80(1 + 0.02 · 5)
- (Parenthesis) Multiply: A = 80(1 + 0.1)
- (Parenthesis) Add: A = 80(1.1)
- Multiply: A = 88
Slope descries both direction and steepness of the line. To determined it from teh graph you must do the rise over run.
