Quadratic since it is x^2 if it was linear it would be something like y=3x+4 and if it was exponential it would be like 4^3x+2=64

An object is dropped from a bridge and allowed to freefall to the ground. The height of the object over time can be modeled usin

ioda

The height at time t is
h(t) = 144 - 16t²

When t = 0, then h = 144.
Therefore the height from the ground is 144 when the object is dropped.

When the object reaches the ground, h = 0.
Therefore
144 - 16t² = 0
t² = 144/16 = 9
t = 3 s

Answer:
The object reaches the ground in 3 seconds.

Beth has 250 comic books in her collection. She begins to sell 20 of them each week. Martin has 80 comic books in his collection

guapka [62]

Answer:

250 - 20 < 80 + 15x

Step-by-step explanation:

Given that

Beth has 250 books and 20 books sold each week

While on the other hand, Martin has 80 books and sell 15 books each week

Let us assume each week be x

Now the equations are

Beth 250 - 20x

Martin 80 + 15 x

Now the inequality would be

250 - 20 < 80 + 15x

562 ÷ Choose... = 14 R2

Zolol [24]

Answer:

7868

Step-by-step explanation:

⇒ This can be written algebraically (with a variable x) as:

562 ÷ x = 14

⇒ Convert the division as a fraction:

$\frac{562}{x}$ = 14

⇒ Multiply both sides by 562 to get rid of the fraction and to isolate the variable x:

562 · $\frac{562}{x}$ = 14 · 562

⇒ Simplify:

x = 7868

Answer: 7868

Hope this helps! :)

Log 54 round to the nearest thousand. I got 1.73239

Nonamiya [84]

Type into your calculator (if you haven't already): log 54.

My result: was similar to yours.

Note, however, that we're supposed to round off these results to the nearest thousandths (not thousand).

Your 1.73239 would need to be rounded off to 1.732, with 2 being the nearest thousandths.
