Answer:
Option 4 is the correct answer 48x⁹ - 72x⁷ + 36x⁵
Step-by-step explanation:
The given expression is,
9x⁵ + 3x(4x⁴ - 3x²)²
<u>To find (4x⁴ - 3x²)</u>²
(a + b)² = a² + 2ab + b²
<u>(4x⁴ - 3x²)</u>² = (<u>4x⁴ )</u>² - 2*<u>4x⁴*3x² + (3x²)</u>²
= 16x⁸ - 24x⁴⁶+ 9x⁴
<u>To find 3x(4x⁴ - 3x²)²</u>
(4x⁴ - 3x²)² =16x⁸ - 24x⁶+ 9x⁴
3x(4x⁴ - 3x²)² = 3x(16x⁸ - 24x⁶+ 9x⁴ ) = 48x⁹ - 72x⁷ +27x⁵
<u>To find 9x⁵ + 3x(4x⁴ - 3x²)²</u>
3x(4x⁴ - 3x²)² = 48x⁹ - 72x⁷ +27x⁵
9x⁵ + 3x(4x⁴ - 3x²)² = 9x⁵+ 48x⁹ - 72x⁷ +27x⁵ = 48x⁹ - 72x⁷ +36x⁵
Therefore the option 4 is the correct answer
Answer:
y = -7.2x + 540
Step-by-step explanation:
to find the slope I used the x-and-y intercepts: (0, 540) and (75, 0)
slope = 540/-75 or -7.2
A) Yes, the two events are independent because P(NF|PB) = P(NF).
