The stone's height (in meters above the water), 3 seconds after ming threw it, is modeled by:
h(x) = -5(x - 1)2 + 45
how many seconds after being thrown will the stone reach its maximum height?

answer: c

step-by-step explanation:

-2 - - 5 = -2+5= 3

6-2= 4

so combine it’s 3/4

answer:

1.25 = r

step-by-step explanation:

the formula for circumference is given by

c = 2*pi *r

we know the circumference   is 7.85

7.85 = 2 * 3.14 *r

7.85 = 6.28 *r

divide each side by 6.28

7.85 /6.28 = 6.28*6/6.28

1.25 = r

answer:

(x + 2)(x + 5)

step-by-step explanation:

for factored form you have to determine what two numbers multiplied by each other equal c that also, when added to each other, equal b.

y= ax^2 + bx + c

a=1

b=7

c=10

the factors of 10 are 1, 2, 5, 10

and 2 + 5 = 7

and in factored form with a = 1

(x + 5)(x + 7)
