Answers

Answer:

Step-by-step explanation:

ignore this i need more letters lol have a good day

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.

What is the correct ratio?
Sin 40=w/28
Tan 40=w/28
Cos 40 = w/28
Sin 40 = 28/w

Answers

Answer:

As we know that

tanФ = opposite ÷ adjacent

Therefore,  the correct ratio is:

tanФ = opposite ÷ adjacent

        = w ÷ 28

       = w/28

i.e.

tanФ = w/28

Step-by-step explanation:

As we know that

tanФ = opposite ÷ adjacent

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

tanФ = opposite ÷ adjacent

Therefore,  the correct ratio is:

tanФ = opposite ÷ adjacent

        = w ÷ 28

       = w/28

i.e.

tanФ = w/28

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

What is a metal?

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.

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

Consider the table that includes the input and output values of a function. Which answer classifies the function using finite differences? The function is quadratic with a constant second difference of –96. The function is quadratic with a constant second difference of 96. The function is cubic with a constant third difference of –96. The function is cubic with a constant third difference of 96.

Answers

Answer:

b, quadratic with constant second difference of 96

Step-by-step explanation:

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

What is Function?

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.
