y = kx

Step-by-step explanation:

You'll need to share the possible answer choices in all future posts.

A function in which y varies directly with x has the form

y = kx, where k is the constant of proportionality.

With more data, it'd be possible for you and me both to identify this constant.

A fireworks company has two types of rockets called Zinger 1 and Zinger 2. The polynomial -16t^2+150t gives the height in feet o

Alisiya [41]

The height of Zinger 1 after 6 seconds is given by the polynomial

$-16 t^{2}+150t$ , for t = 6,

so the height is $-16 *6^{2}+150*6=-576+900=324$ (feet)

The height of Zinger 2 after 6 seconds is given by the polynomial

$-16 t^{2}+165t$ , for t = 6,

so the height is $-16 *6^{2}+165*6=-576+990=414$ (feet)

At the moment the rockets explode, Zinger 2 is 414-324=90 (feet)

higher than Zinger 1.

Answer: 90 feet

Afina-wow [57]

Solution-

∵ she earns $50 per day and she worked 30 days in the quarter.

∴ Her total earning for this period = $(50×30) = $1500.

Also she earns 3% commission for her sales.

∴ Her total earning by commission =3% of $4596= $ (3×4596)/100

= $ 137.88

∴Total amount earned by Paige= $137.88+$1500

=$ 1637.88
