Ms. walker's science class is doing an egg drop experiment from the balcony of their school. each egg is protected by a contraption that the students collectively designed. the height of the egg, in feet, after x seconds is given by the expression below.

-16x^2+35

what do the zeros of the expression represent?

a.
the horizontal distance traveled by the egg
b.
the time at which the egg reaches its maximum height
c.
the maximum height of the egg
d.
the time at which the egg reaches the ground

The answer is (D) ⇒ the time at which the egg reaches the ground

Step-by-step explanation:

∵ h(x) = -16x² + 35 ⇒ x is the time in seconds

∵ The zeroes of the expression means the value of x when h(x) = 0

  and h is the height of the egg form the ground

∴ -16x² + 35 = 0

∴ 16x² = 35

∴ x² = 35/16 = 2.1875

∴ x = √2.1875 = 1.479

∴ The egg reaches the ground after 1.479 sec.

∴ The zeroes of the expression means the time at which the

   egg reaches the ground

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
