Answer:

i think its D

f(x) = x-3 and g(x) = x+11

f(x) *g(x) = (x-3)(x+11) = x^2 +11x -3x -33 = x^2 +8x -33

hope this helped :3

Step-by-step explanation:

(x-3)(x+11)=x^2+11x-3x-33=x^2+8x-33

Answer:

ductile

Step-by-step explanation:

Two other properties of copper that show it is a metal are malleable and ductile.

A metal is a substance that exhibits a better surface when properly processed, refined, or shattered, and transports warmth and electricity rather well. Generally speaking, metals generally malleable and ductile. These characteristics are the outcome of the metallic link that exists here between metal particles or atoms.

This suggests that the metal is ductile, malleable, and a superb energy and heat transmitter. It can be cleaned to a bright gloss and is smoother than zinc.

Unlike gold and silver, it is a member of group Ib on the regular chart. The chemical stability of copper is minimal. The metal when presented at room temperature will be in the solid phase.

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:

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.

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.

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.

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
