Answer:

x = -9

Step-by-step explanation:

I'm sorry, but I won't be explaining it, however I will show every step.

Let's begin.

4x - 12 = -7x - 111

4x - 12 + 7x = -7x - 111 + 7x

11x - 12 = -111

11x - 12 + 111 = -111 + 111

11x + 99 = 0

11x + 99 - 99 = 0 - 99

11x = -99

11x/11 = -99/11

x = -9

The height of a projectile in the air t seconds after it is shot can be modeled by the function y = -16t^2 + 3200t + 2, where t

Talja [164]

Answer:

160002 feet

Step-by-step explanation:

y(t)=-16t^2+3200t+2

We need y’ to find a maximum

y’(t)=-32t+3200

y’(t)=0 if t=100

Notes that y’(t)>0 if t<100, and fot t>100 y’(t)<0. Now we can conclude that y(t) has maximum in t=100

Y(100)=-16*10000+3200*100+2

Y(100)=160002 feet

A box contains paper clips of three different sizes. The numbers of each size of paper clip are listed below.

Bond [772]

Answer:

$\frac{7}{10}$

Step-by-step explanation:

Add all paper clip sizes together:

$100 + 250 + 150 = 500$

They want the probability of either a small or medium being chosen, so you add both paper clips sizes together.

$100 + 250 = 350$

Now put the number of small and medium paper clips together over the total number of paper clips to find the probability.

Can divide 350 and 500 by 50, which simplifies it down to 7/10.

$\frac{350}{500} = \frac{7}{10}$
