Answer:

Step-by-step explanation:

f(-3) = 2 * (-3)^2           h(6) = -4 * 6          g(-2) = 3*-2 -1            f(-4)= 2*(-4)^2

       =  2* 9                           = - 24                     = -6 -1                       = 2* 16

      = 18                                                              = -7                            = 32

Answer:

I think it's 9 miles every day.

Step-by-step explanation:

Chen bikes 9 miles every day. Therefore, option B is the correct answer.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

The given table is

Days    Miles

  1          9

  2        18

  3        27

  4        36

  5        45

We know that, the formula to find the speed is Speed = Distance/Time

Here, speed =9/1 = 9 miles per day

Speed =18/2 = 9 miles per day

Speed =27/3 = 9 miles per day

Speed =36/4 = 9 miles per day

Speed =45/5 = 9 miles per day

Chen bikes 9 miles every day. Therefore, option B is the correct answer.

The Pythagorean theorem tells you ...

  PR² = PQ² +QR²

Filling in the given dimensions, you have ...

  PR² = 5² + 8²

  PR = √89

Answer:

300 kilometers.

Answer:

500/3.

Step-by-step explanation:

4(t+25)=4(t+50)−4(0.15t)

4t + 100 = 4t + 200 - 0.6t

Subtract 4t from both sides

100 = 200 - 0.6t

-0.6t + 200 = 100

-0.6t = -100

0.6t = 100

6t = 1,000

3t = 500

t = 500/3, or 166.6666667, or 166 and 2/3.

Hope this helps!

Step-by-step explanation:

4(t+25)=4(t+50)-4(0.15t)

4t+100=4t+200-0.6t

4t-4t+0.6t=200-100

0.6t=100

Answer:

what is the question

Step-by-step explanation:

Answer:

(k+3)(k+4)

The zeros are -3 and -4

Step-by-step explanation:

k2+7k+12

The middle number is 7 and the last number is 12.

This means we need two numbers that:

Add together to get 7

Multiply together to get 12

to fit in this equation (k+_)(k+_)

in this equation, it would be 3 and 4

3+4 = 7

3*4 = 12

Now we fill in the blanks to get

(k+3)(k+4)

To get the zeros, use the equations

k+3=0 and k+4=0

You end up with

k=-3 and k=-4
