Answer:

the equation for the mid line is y = -2.5

Step-by-step explanation:

The given equation is

f(x)=3cos(x)-2.5

On comparing this equation with f(x)=Acos(Bx+C)+D

A = 3

B = 1

C = 0

D = -2.5

The mid line for the equation is

y = D

Substituting the value of D

y = -2.5

Thus, the equation for the mid line is y = -2.5

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!
Kamila [148]

Answer:

Twelve tickets cost $30 --> True

Thirty tickets cost $12 --> False

Each additional costs $2.50 --> True

The table is a partial rep --> True

ordered pairs --> False

Step-by-step explanation:

Twelve tickets cost $30 --> True, you can literally see that in the table

Thirty tickets cost $12 --> False, 30 is not in the table so you don't have that information. Besides, $12 is an unlikely low value for so many tickets.

Each additional costs $2.50 --> True, you can see the difference in the TotalCost column to be consistently 2.50.

The table is a partial rep --> True, values below 11 are not shown for example.

ordered pairs --> False --> Then the x value should be first, e.g., (11, 27.50), since the cost y is a function of the number x.

Will mark brainliest please help Debbie notices that the amount owed on her monthly heating bill varies inversely with the avera
Alekssandra [29.7K]

Answer:

The bill is $1837.5

Step-by-step explanation:

Given

B = Bills

T = Temperature

B\ \alpha\ \frac{1}{T} --- The variation

T = 35; when B = 210

Required

Find B when T = 40

B\ \alpha\ \frac{1}{T}

Express as an equation

B = \frac{k}{T}

Make k the subject

k = BT

<em>T = 35; when B = 210</em>

k = 35 * 210

k = 7350

When T = 40, we have:

k = BT

7350 = B * 40

Make B the subject

B = \frac{7350}{4}

B = 1837.5

What is an expression so that the product of a whole number and a decimal is 0.28
alisha [4.7K]

You may go the super easy way and choose 1 as the whole number and 0.28 as the decimal number. Then you'd obviously have 1\cdot 0.28=0.28

Otherwise, to be a bit more creative, you can observe that

0.28=\dfrac{28}{100} = \dfrac{14}{50} = \dfrac{7}{25} = 7\cdot \dfrac{1}{25}

And since 1/25=0.04, you can also choose 7 as the integer, and 0.04 as the decimal to get

7\cdot 0.04=0.28
