Answer:
Please check the explanation.
Step-by-step explanation:
Given
f(x) = 3x + x³
Taking differentiate



solving






now solving




Thus, the expression becomes


Thus,
f'(x) = 3 + 3x²
Given that f'(x) = 15
substituting the value f'(x) = 15 in f'(x) = 3 + 3x²
f'(x) = 3 + 3x²
15 = 3 + 3x²
switch sides
3 + 3x² = 15
3x² = 15-3
3x² = 12
Divide both sides by 3
x² = 4



Thus, the value of x will be:

A right angle = 90 degrees
A round angle = 360 degrees
1. 3 x 90 = 270 degrees
2. 4 x 90 = 360 degrees
3. 1 1/2 x 90 = 135 degrees
4. 2 1/3 x 90 = 210 degrees
5. 2/9 x 360 = 80 degrees
6. 3 3/8 x 360 = 1,215 degrees
Answer:
89°
Step-by-step explanation:
It is the first of a new study from the University of ÷|gsuj the most of the world the first time in a long time and money on what will happen in a way that would have to be careful about the future of this is to proa vide make be the it
We have to factor the polynomial.
x^8+3x^5
Find the GCF between 1,3,x,5,8
The GCF is x^5
Divide the polynomial by x^5
x^5(x^3+3)
