Sorry I'm not really sure what you're asking for, but I think you want the line, so here
Answer:
x = 2 x = -6
Step-by-step explanation:
2 (x+2) ^2-4=28
Add 4 to each side
2 (x+2) ^2-4+4=28+4
2 (x+2) ^2= 32
Divide by 2
2/2 (x+2) ^2=32/2
(x+2)^2 = 16
Take the square root of each side
sqrt((x+2)^2) =±sqrt( 16)
x+2 = ±4
Subtract 2 from each side
x+2-2 = -2±4
x = -2±4
x = -2+4 and x = -2-4
x = 2 x = -6
A) 500 × (1.015)^t = f(t) <span>
b)
500 </span>× (1.015)^t = 800 divide by 500
(1.015)^t = 1.6 solve for t
t <span>≈</span> 31.57 years

3/4x + 5 - 1/2 x=3 = -8
I believe this is the right answer :)
Answer:
See example below.
Step-by-step explanation:
You'll need the height and radius of the cone to find the volume. Use the example below to find your solution.
Example:
The volume of the cone is found using the volume formula for a cone .
Substitute h=18 and r = 6.
A half sphere is a hemisphere. The volume of a hemisphere is half of . Substitute r=6.
However the hemisphere is half this so it is .
The total volume for this example is 452.6 + 678.24 = 1,130.84
