Answer: (-2, 1), (-4, -3)
Step-by-step explanation:
y = x² + 8x + 13
y = 2x+5
x² + 8x + 13 = 2x+5
x² + 6x + 13 = 5
x² + 6x + 8 = 0
x² + 2x + 4x + 8 = 0
(x+2)(x+4)=0
<u>x=-2 or x=-4</u>
y=2(-2)+5
y=-4+5
<u>y=1</u>
y=2(-4)+5
y=-8+5
<u>y=-3</u>
The value of that fraction depends on the value of 'x'. Whatever 'x' happens
to be at the moment, the fraction is equal to about 61.1% of it. And if 'x' ever
changes, then the value of the fraction also changes, immediately.
Answer:
t=1.06x+10 where x=The amount of tickets bought
Step-by-step explanation:
you multiply x by 1.06 to add the extra tax onto it.
You add the 10 to add the $10 booking fee
All you need to know is that
So, the first function grows exponentially and the second decays exponentially. The rate of growth/decay are the bases of the exponentials, which means 1.08 and 0.205
Volume of a cylinder is pi*(radius)^2* height. pi is 3.14 and radius is half of diameter which would be 3. height is 8. Thus volume of a cylinder in your case is pi*9*8 or 72*pi which is approximately 226.19
