Answer:

Step-by-step explanation:

Perimeter = 20.56mm

= 20.56

D = 20.56 ÷

D = 6.54 mm

Perimeter of the Semicircle = half the circle arc + the straight line (Diameter)

Semicircle = 0.5(20.56) + 6.54cm

Write a quadratic function f whose zeros are 3 and 10

Anettt [7]

Answer:

$f(x) = {x}^{2} - 13x + 30$

Step-by-step explanation:

A quadratic equation may be expressed as a product of the two binomials. The roots of the equations are 3 and 10, so the factors are (x-3) and (x-10).

f(x) = (x-3)(x-10)

f(x) = x^2 - 13x + 30
