d) What are the values for coefficients a, b, and c in the quadratic equation for Daredevil Danny’s practice jump? (5 points)
SIZIF [17.4K]

Answer:

a = -0.32

b = 16

c = - 168

Step-by-step explanation:

In the figure attached, the quadratic function is shown. We can model it as follows:

y = a*(x - x1)*(x - x2)

where (x1, 0) and (x2, 0) are its roots

From the picture, roots are (15, 0) and (35, 0), replacing them into the equation:

y = a*(x - 15)*(x - 35)

and the vertex is at (25,32), replacing into the equation:

32 = a*(25 - 15)*(25 - 35)

32 = a*(-100)

a = 32/(-100)

a = -0.32

Applying distributive property:

y = -0.32*(x - 15)*(x - 35)

y = -0.32*(x² - 35x - 15x + 525)

y = -0.32x² + 16x - 168

which corresponds to the general form:

y = ax² + bx + c

Find the power of 3/8^3
GREYUIT [131]

(3/8)³ = (3/8)(3/8)(3/8)

Multiply across:

(3/8) x (3/8) = 9/64

Simplify:

(9/64)(3/8) = 27/512

27/512 is your fraction answer (cannot be reduced).

To find the decimal answer, divide:

27/512 = 0.05

0.05 (rounded) is your decimal answer

hope this helps
