Answer:
nine dollars and 27 cents
Step-by-step explanation:
if u minus 14.50 minus 5.25 u get 9.27 9 dollars and 27 cents
Yw!
Should have subtracted 3x
The formula is L = 2 pi r * (angle/360). We have what we need to figure it out. Do the work inside the () first. 72/360 = .2. So we have 2 pi (5) (.2). Do all that multiplication to get L = 2pi
Answer:
(2,-9)
Step-by-step explanation:
Multiply out the polynomial to get:
x^2-4x-5
the vertex formula is -b/2a (use the coefficients of the equation above)
-(-4)/2(1) = 4/2 = 2
we know the x value of the vertex is 2. Now we can plug that into the original equation to get the y value.
(2-5)(2+1)
(-3)(3) = -9
so the coordinate is (2,-9)
