9514 1404 393

Answer:

  A. 2

Step-by-step explanation:

When you don't know if a number like 256 is a power of anything, it can work reasonably well to start by simply dividing by the factors you know.

  • 256/2 = 128
  • 128/2 = 64
  • 64/2 = 32
  • 32/2 = 16
  • 16 = 2^4, so 256 = 2^4 · 2 · 2 · 2 · 2 = 2^8

The 8th root of 2^8 is 2, choice A.

A fruit stand has to decide what to charge for their produce. They need \$10$10 for 44 apples and 44 oranges. They also need \$1
KatRina [158]

Answer:

<em>We can't find a unique price for an apple and an orange.</em>

Step-by-step explanation:

Suppose, the price of an apple is x and the price of an orange is y

They need $10 for 4 apples and 4 oranges. So, the first equation will be.......

4x+4y=10 ........................................(1)

They also need $15 for 6 apples and 6 oranges. So, the second equation will be........

6x+6y= 15 ........................................(2)

Dividing equation (1) by 2 on both sides :  2x+2y= 5

Dividing equation (2) by 3 on both sides :  2x+2y=5

So, we can see that both equation (1) and (2) are actually same. That means, we will not get any unique solution for x and y here. Both x and y have <u>"infinitely many solutions"</u>.

Thus, we can't find a unique price for an apple and an orange.

An arrow is shot vertically upward at a rate of 160 feet per second from ground level. Use the projectile formula
Bumek [7]

Answer:

after 10 seconds

Step-by-step explanation:

h=-16t^2+v0*t+h0

ground level is h0 with a measure of 0

160 is v or velocity

0=-16t^(2)+160t+0

0=-16t^(2)+160t

0=16t(-t+10)

0/16t=(-t+10)

0=-t+10

-10=-t

10=t

t=10
