The answer would be that the ladder will touch the wall at 8 feet.
Answer:
1. 7¹⁰
2. 9⁸
Step-by-step explanation:
1. 7 = 7¹
Hence, using the rules of indices..... you would add the exponents when numbers that have the same base are multiplied together.
7⁹⁺¹ = 7¹⁰
2. Add exponents
9²⁺⁶ = 9⁸
Answer:
51
Step-by-step explanation:
Given
P(x) = 2x³ + 4x² - 10x - 9, then
P(a) = 2a³ + 4a² - 10a - 9 ← substitute x = a into P(x)
To evaluate P(3) substitute a = 3 into P(a)
P(3) = 2(3)³ + 4(3)² - 10(3) - 9 = 54 + 36 - 30 - 9 = 51
Since P(3) ≠ 0 then (x + 3) is not a factor of P(x)
<h3>The surface area of a piece of paper is
</h3>
<em><u>Solution:</u></em>
surface area of a piece of paper = 137 sq cm
<em><u>Use the fact that 10 mm = 1 cm to convert this area to mm^2</u></em>
Then,
<em><u>Convert 137 sq cm to sq mm</u></em>
Thus, surface area of a piece of paper is
