10 miles per hour

Step-by-step explanation:

60 / 6 = 10

Therefore, she is jogging 10 miles per hour.

Pretty sure this is running, not jogging.

The rate of jogging is 10 miles per hour

The calculation can be done as follows

Kelsey jogs a total of 60 feet in 6 seconds

The rate is = 60/6

= 10 miles/hour

Hence the rate in miles per hour to the nearest tenth is 10 miles per hour

Answer:

y=x-3

Step-by-step explanation:

The slope is just x, and the y intercept will be one over from (1,-2) which is (0,-3), so -3 is the starting point.

Answer:

As we know that

Therefore,  the correct ratio is:

tanФ = opposite ÷ adjacent

        = w ÷ 28

       = w/28

i.e.

Step-by-step explanation:

As we know that

Given the triangle with an angle of 40°.

As the opposite of an angle 40° is the length 'w', and adjacent to the angle

40° is the length '28'.

As we know that

Therefore,  the correct ratio is:

tanФ = opposite ÷ adjacent

        = w ÷ 28

       = w/28

i.e.

Answer:As we know that tanФ = opposite ÷ adjacentTherefore,  the correct ratio is:tanФ = opposite ÷ adjacent        = w ÷ 28       = w/28i.e.tanФ = w/28Step-by-step explanation:As we know that tanФ = opposite ÷ adjacentGiven the triangle with an angle of 40°.As the opposite of an angle 40° is the length 'w', and adjacent to the angle 40° is the length '28'.As we know that tanФ = opposite ÷ adjacentTherefore,  the correct ratio is:tanФ = opposite ÷ adjacent        = w ÷ 28       = w/28i.e.tanФ = w/28

Answer:

You could buy 3 cantaloupes.

Step-by-step explanation:

So, you have $6. Now, what we would do is (O is 1 cantaloupe):

If O cost $2, do the following:

O O O O O

2  2  2  2 2

Now, lets count up til we get 6:

2 + 2 = 4; 4 + 2 = 6;

After you have done that step, count how many 2's you see in that equation. I see 3.

Therefore, you could buy 3 cantaloupes.

Answer:

b, quadratic with constant second difference of 96

Step-by-step explanation:

The function is cubic with a constant third difference of 96.

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Using differences:

X            f(x)             first difference          second difference             third

3            39                        -                                    -                                -

5            187             (187-39)/2= 74                       -                                -

7            551            (551-187)/7-5 = 182     182 - 74/2 = 54                   -

9           1227          (1227-551)/(9-7)=338   338-182/2=78          78-54/2 = 12

11           2311           (2311-1227)/2=542      542-338/2=102       102-78/2 = 12

According to table,

The function is cubic, because the third average change rate is constant of 12.

12>0, so the third difference is >0 then -96 is false.

Thus, the function is cubic with a constant third difference of 96.

Answer:

The average rate of change from 0 to 20 years old is -2.

Step-by-step explanation:

Average rate of change means slope.

slope = y2 - y1 / x2 - x1

Pick any points between 0-20. They have given on the graph already (0, 112) and (20, 72) so plug it into slope equation.

112 - 72/ 0 - 20

40/-20

= -2

The average rate of change from 0 to 20 years old is -2.
