Answer:8
Step-by-step explanation:
Radius = 13 inches
Circumference of wheel = 1 revolution
2πr = 2 x 3.14 x 13 = 81.64 inches
1 revolution = 81.64 inches
30 revolutions = 2449.2inches
When an exponent is outside the parentheses, you "distribute" it to the other exponents inside the parentheses.
(4^p)^3 would become 4^3p
(4^1)^3 would become 4^3
When the bases are the same, you just simply add the exponents.
Let's just ignore the bases so it'll look less confusing.
3p + 3 = 15
Subtract 3 from both sides.
3p = 12
Divide both sides by 3.
<em>p = 4</em>
Angle 2 = 46°
Angle 3 = 180-46=134°
(2x² - 4x + 3) + (x² - 4x - 4) =
2x² - 4x + 3 + x² - 4x - 4 =
3x² - 8x -1
