The table shows how far a distance runner has traveled since the race began. What is her average speed, in miles per hour, durin
grigory [225]

Answer:

5\ \frac{miles}{hour}

Step-by-step explanation:

<u><em>The complete question is</em></u>

The table shows how far a distance runner has traveled since the race began. What is her average speed, in miles per hour, during the interval 0.75 to 1.00 hours?

Time Elapsed (Hours) Miles Traveled (Miles)

0.50 2.00

0.75 3.50

1.00 4.75

Let

x ----> the time in hours

f(x) ----> the distance traveled in miles

so

we have

x (Hours)   0.50   0.75  1.00

f(x) (Miles)  2.00   3.50  4.75

we know that

To find the average speed, we divide the change in the output value by the change in the input value

the average speed is equal to

\frac{f(b)-f(a)}{b-a}

In this problem we have

a=0.75

b=1.00

f(a)=f(0.75)=3.50  

f(b)=f(1.00)=4.75

Substitute

\frac{4.75-3.50}{1-0.75}

\frac{1.25}{0.25}

5\ \frac{miles}{hour}

How do I solve this?
Alona [7]

Answer:

3^{7}

Step-by-step explanation:

Multiplying exponents is the same as adding them.

^2 x ^5 is the same as 2 + 5 = 7

You have to keep the bases the same so your answer is 3^{7}

Are the equations -2x=10 and -5x=25 equivalent
Natasha_Volkova [10]
To equations are equivalent if and only if they have the same solution set.

Solve for both of the equations.

-2x = 10
x = -5 <-- Divide both sides by -2

-5x = 25
x = -5 <-- Divide both sides by -5

Both have the solution -5.

So, yes both are equivalent.
