The circumference of a circle is the diameter times pi. So, 66 ft = pi x d. 66 divided by pi is roughly 21, so the diameter is 21 ft. 21 + 4 = 25. 25 x $0.45 = $11.25

The answer would be $33.3 because if you added 66+4+4 that would be 74. 74•45 (45 as in cents) and that would equal 333 and add a decimal point to make it 33.3

Write an equation for the quadratic graphed below
uranmaximum [27]

Answer:

Step-by-step explanation:

LOL The graph doesn’t match the y intercept :)

Anyway

If we have point (0,-3) we have a quadratic of

y=ax^2+bx-3 we are given points (-1,0) and (2,0) so

a-b-3=0 and 4a+2b-3=0

4a+2b-3+2(a-b-3)=0

4a+2b-3+2a-2b-6=0

6a-9=0

6a=9

a=1.5, since a-b=3

1.5-b=3

b=-1.5

y=1.5x^2-1.5x-3

Write an equation for the line that passes through (2,10),(0,4)
Y_Kistochka [10]
I'm going to go right ahead and assume that we're talking about a linear equation.

The linear equation passing through the points given is y=3x+4, since it satisfies both of the points given.
