Step-by-step explanation:
x^4 -64 = 0
x^4 = 64
x^4=√64
x = -4 or +4
Answer:
- 48
Step-by-step explanation:
by PEDMAS, we evaluate the exponent first before the multiplication
(-12)·(-2)²
= (-12)·(4)
= - 48
Answer:
cubic polynomial
Step-by-step explanation:
Given polynomial is ![\[h(x)=-6x^{3}+2x-5\]](https://tex.z-dn.net/?f=%5C%5Bh%28x%29%3D-6x%5E%7B3%7D%2B2x-5%5C%5D)
A polynomial of degree 1 is a linear polynomial.
A polynomial of degree 2 is a quadratic polynomial.
A polynomial of degree 3 is a cubic polynomial.
In this case the exponent with the maximum value in the polynomial is 3.
Hence the degree of the polynomial h(x) is 3.
Hence the given polynomial is a cubic polynomial.

Answer:
- adult: 325
- children's: 225
Step-by-step explanation:
It usually works well to let a variable represent the higher-value item in the mix. Here, we can let 'a' represent the number of adult tickets sold. Then the total revenue is ...
1.50a +1.00(550 -a) = 712.50
0.50a = 162.50 . . . . . . . . . . . . . subtract 550 and collect terms
a = 325
c = 550 -325 = 225
325 adult and 225 children's tickets were sold.
