Answer = 4 ft
Radius = Circumference / (pi x 2)
Radius = 8 / (4 x 2)
Radius = 4
Answer:
c = 4(d) + .43(m)
Step-by-step explanation:
We can test this by plugging in numbers for each of the variables. Let's say Jamal drove 5 miles over 2 days.
c = 4(2) + .43(5)
c = 8 + 2.15
c = $10.15
Have a nice day!
Answer:
Step-by-step explanation:
it is maximum.
when leading coefficient of x² is negative,
It is downward parabola.
or
y=-2x²+10x+1
=-2(x²-5x+(-5/2)²-(-5/2)²)+1
=-2(x-5/2)²+2×25/4+1
=-2(x-5/2)²+25/2+1
=-2(x-5/2)²+27/2
maximum value of y is 27/2 and is attained at x=5/2
vertex is (5/2,27/2)
