multiply sides together.
Answer:
f(x)= -2(x-8)²+6
Step-by-step explanation:
First graph the points
you will get a parabola that has a vertex in (8,6) wich means h= 8 and k=6
so the equation is
to get a we will replace by the coordinates of a point for example (6,-2)
- -2 = a(6-8)²+6
- -2 = a*4+6
- -2-6 = 4a
- -8 = 4a
- a = -2
a is negative wich makes sense since the parabola opens down
Answer:
1
Step-by-step explanation:
The radius is half the size of the diameter.
2 / 2 = 1
Answer:
<em>C. 94</em>
Step-by-step explanation:
Take in account for PEMDAS: Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.
First is to find the answer within the innermost parenthesis:
(4²+1).
Find the exponent of 4², which is 16, leaving you the equation of
16+1, which equals to 17.
Next you multiply 3 by 17 (since the parenthesis of 17 borders 3):
17×3=51.
Next, multiply 51 by 2 (same rule as 3×17).
51×2=102.
After this you get 102-2³. Now, find 2³=2×2×2=8
This gets you to 102-8, ending up with your answer of 94.
