Answer:
Step-by-step explanation:
Here, you should find the area of the cylinder. Remember the superficial area of a cylinder is
( )
Since we have r= 4 and h=7, we get

To find the cost you only need to multiply area A by 0.08. That is

Step-by-step explanation:
x-intercept: where y = 0
Set y to zero to find x.
0 = ½x + 3
-3 = ½x
x = -6
(-6, 0)
Answer:
Since there are two cars, each car, then, drove 104/2 = 52 miles. But one car is traveling 8 miles per hour faster.
Step-by-step explanation:
Equation of a circle with center at (h,k) and radius of r is
(x-h)²+(y-k)²=r²
so
center (-7,10) and diameter 6
remember, diameter/2=radius=6/2=3
so
equation is (x-(-7))²+(y-10)²=3²
(x+7)²+(y-10)²=9
