Answer:
Math is considered to be a part in everyones life, for example, you use math to throw a ball, like the force you use, or the height of the ball. Math is an important concept, and is lingering in our everyday lives, but the reason we take math is to find out of its exsitence, and use it for engineering, etc.
Step-by-step explanation:
The constants are 2, -10, and 5
the variables are x and y
Answer:
22.7
Step-by-step explanation:
Okay so the situation given shows a right triangle with the two sides being 7.6 and 18.2. So we can find the angle of elevation using tangent, which is tan-1*7.6/18.2. I got 22.66 so 22.7
The equations that are true for x = -2 and x = 2 are
-4 = 0 and 4
= 16
<h3>What is an equation?</h3>
An equation is a mathematical statement that establishes the equality of two quantities.
Analysis:
Testing the equation x2 - 4 = 0
for x = 2,
- 4 = 4-4 = 0
for x = -2 = (-2)2 - 4 = 4-4 = 0
Therefore x2-4 = 0 is true
Testing for 4x2 =16
for x = 2 , 4(2) ^2 = 4x4 = 16
for x = -2 4(-2)^2 = 4(4) = 16.
All other equations are not true except these two.

Answer:

Step-by-step explanation:
The principal of the amount P is deposited in an account that earns simple interest.
The interest that the account earns is r annual interest rate expressed as a decimal.
The principal P is invested for t years.
Therefore, the matured amount A will be given by
Hence, this is the formula that can calculate the A if P, r and t are known. (Answer)
