Answer:
- -28y^4 - 7y^3 + 62y^2 + 5y - 30
Step-by-step explanation:
<u>Opening the parenthesis and simplifying by combining like terms:</u>
- (6 - y - 4y^2)(-5 + 7y^2) =
- 6(-5) +6(7y^2) - y(-5) -y(7y^2) -4y^2(-5) -4y^2(7y^2) =
- -30 + 42y^2 + 5y - 7y^3 +20y^2 -28y^4 =
- -28y^4 - 7y^3 + 62y^2 + 5y - 30
5^7 = 5 × 5 × 5 × 5 × 5 × 5 × 5 = 78,125
5^-9 = 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 = 0.000000512
5^-5 = 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 = 0.00032
78,125 × 0.000000512 × 0.00032 = 0.0000128
Answer: 0.0000128 or 1.28 x 10^-5
Answer: E
Taking a poll in the lunchroom would be the most accurate population sample.
Let X represent the length of the chord.
By using Pythagoras' Theorem:
4^2 + (X/2)^2 = 15^2
(X^2)/4 = 209
X^2 = 836
X = 28.91
