Answer:
(b) {-8, 2}
Step-by-step explanation:
The given equation
x³ +6x -16 = 0
cannot be factored in integers. It has one irrational real root near x=1.759, and two complex roots.
__
Perhaps you want to factor ...
x² +6x -16 = 0
(x +8)(x -2) = 0
This has solutions x = -8 and x = 2 that make the factors be zero.

<em>Additional comment</em>
"Cubed" refers to an exponent of 3.
1 light year = 9.46 x 10^12 km. Therefore how many light years = 5.9 x 10^13?. Do cross multiplication you'll get. 5.9x10^13 / 9.46x10^12 = 6.23 light years. So d is the correct answer.
Answer:
Slope-intercept equation.
Step-by-step explanation:
y = mx + b
Hello from MrBillDoesMath!
Answer:
27 x^2 sqrt(x^3) sin(x^3) - 9/2 sqrt(x^1/2) sin(x^1/2)*x^(-1/2)
Discussion:
Let f(t) - 9 sqrt(t) sin(t), then
y' = f(x^3) * d(x^3)/dx - f(sqrt(x)) * d(x^1/2)/dx
= (9 sqrt(x^3)sin(x^3)) * 3x^2 - (9 sqrt(x^1/2)sin(x^1/2)) * (1/2) x^-(1/2)
= 27 x^2 sqrt(x^3) sin(x^3) - 9/2 sqrt(x^1/2) sin(x^1/2)*x^(-1/2)
Hope I didn't make a "bozo" error differentiating things!
Thank you,

4√7
This is similar to collecting like terms in algebra
take out a common factor of √7 from each term
= √7( 5 + 1 - 2 ) = 4√7
