3.5 and 3 write a quadratic equation with each pair of values as roots
VLD [36.1K]

Hello from MrBillDoesMath!

Answer:  x^2 - 6.5x + 10.5 = 0

Discussion:

If the roots are 3 and 3.5, then the quadratic equation is

(x -3 ) ( x - 3.5) = 0

or

x * (x - 3.5) - 3 (x - 3.5) = 0

or

X^2 - 3.5X - 3X + 3(3.5) = 0

or

x^2 - 6.5x + 10.5 = 0



Thank you,

MrB

Naddik [55]

Answer; 47.27 Inches

Let the height of Dagne be x.

Now we are told that she can do a vertical jump that is 27.5%  of her height. This is represented as 0.275x.

Now we are told the height she can jump is 13.2. Thus;

0.275x = 13.2

x = 13.2/0.275

x = 47.27 inches
