Answer:
w=67°
Step-by-step explanation:
First you solve for x. 12x+11=x. X would be 1. Then you plug in 1 for x and add the w to the equation. 12(1)+11+w=90. after solving that you will get the total for w. which should be 67°
Hello,
x²+y²-10x+6y+18=0
==>(x²-2*5x+25)+(y²+2*3y+9)+18-25-9=0
==>(x-5)²+(y+3)²=16
Radius is 4.
Center (5,-3)
Answer:
An experimental study
Step-by-step explanation:
An experimental study should be used. This will enable the energy drink manufacturer to have an experimental group and control group. Using experimental study, the effect of independent variables on the dependent variables can be determined with the amount of the drink consumed as the controlled factor.
Answer:
LAST OPTION: 
Step-by-step explanation:
For this exercise it is important to remember the Power of a power property, which states that:

The expression given in the exercise is:

Therefore, in order to simplify it, you must apply the Power of a power property explained before.
Then, you get the following expression:

As you can notice, the expression obtained matches with the expression provided in the last option.
Answer:
C
Step-by-step explanation:
Use the circle area formula.
A = pi * r^2
A = pi * 4^2
A = pi * 16
A = 50.27
