Answer:
A
Step-by-step explanation:
Check the solution by substituting x =
into the left side of the equation
2sin²x - sinx - 1
= 2sin²(
) - sin (
) - 1
= 2(1)² - 1 - 1
= 2 - 1 - 1
= 0
= right side
is therefore a solution to the equation
Answer:
x ---- y
1 ---- 3
4 ---- 12
6 ---- 18
Step-by-step explanation:
Given

Required
Create a table that represents this scenario
Because x represents time, x can not be negative. So, the domain of x is:

Assume 

Assume x = 4

Assume x = 6

Hence, the table is:
x ---- y
1 ---- 3
4 ---- 12
6 ---- 18
Answer:
The cube root and square root are not given, but I'm going to give a chart that might help.
Square roots:
2 = √4
3 = √9
4 = √16
5 = √25
9 = √81
10 = √100
Cube roots:
2 = ^3√8
3 = ^3√27
4 = ^3√64
5 = ^3√125
9 = ^3√729
10 = ^3√1000
Answer:
7
Step-by-step explanation:
No. of pizza Ronnie stacked = 0.25 × 40
= 10
No. of pizza Mack stacked = 9
No. of pizza Kim stacked =
× 40
= 14
No. of pizza Ada stacked = 40 - 10 - 9 - 14
= 7
