the value of sqroot -4 is not -2 because

Answer:

$2,651

Step-by-step explanation:

The first step is to find what 1.5% of $2,600 is.

Secondly, divide 2600 / 100 = 26

Finally, multiply 26 by 1.5 = 39.

Add 39 and 12 to 2600 = $2,651.00 total earnings for the month.

Answer:

15,011

Step-by-step explanation:

Because 1.5 percent of 825,000 is 12375. She gets 2,600, so add that, and 12 times 3 for 3 houses is 36.

Add 12,375+2,600+36, you get 15,011!

f(-4) = -16 - 9

f(-4) = -25

Answer:

17 units

Step-by-step explanation:

You can find the lenght of drawing a triangle and counting the x units and y units, thereby the AB would be the hypotenuse.

X units ( base ) = 15 units

Y units ( height ) = 8 units

AB = root of 8^2 + 15^2

AB = root of 289

AB = 17 units

Answer:

8 ft

Step-by-step explanation:

with the ratio of 2:3, im assuming 2=height and 3=length

multiply both sides of the ratio by a certain number so you can get the given length.

2:3 - multiply both sides by 4- 8:12

the height is 8

Answer:

8 ft

Step-by-step explanation:

You multiply both side by 4 and you get 8/12.

So the height is 8 ft.

What is Function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

We know that the function are relation when the input values only be distinct and the output values can be different or same.

So, according to that

{(1,3), (3, 7), (5, 11), (7, 15), (9, 19)} is a function.

and, {(1, 3), (1,7), (5, 11), (5, 15), (9, 19)} is not a function.

and, {(-2, 4), (-1, 1), (0, 0), (1, 1), (2, 2)} is a function

and, {(2,4), (1, 1), (0,0), (1,-1), (2,-4)} is not a function.

and, {(6,3), (4, 1), (2, 1), (0, -1), (-2,-3)} is a function.

Answer:

The total bill = $20.85

Annie = $7.95

Suz = $4.17

Cynthia = $8.80

Step-by-step explanation:

Let the total bill = $x

For Annie

Annie, you had 3 slices and a medium soda so you should pay one-third of the bill. I'll chip in a dollar more than that, replied Annie.

Annie = 1/3 of x + $1

= 0.33x + $1

For Suz

And since you had only 2 slices and also ordered a small soda, you should pay 20% of the bill.

20% of x = 1/5x

= 0.2x

Cynthia said I ate 3 slices and had a large soda so I'll pay the remaining $8.80.

0.33x + $1 + 0.2 x + $8.80 = $x

Collect like terms

$1 + $8.80 = x - 0.33x - 0.2x

$9.80 = x - 0.53x

$9.80 = 0.47x

x = $9.80/0.47

x = $20.85106383

≈ $20.85

Therefore,

For Annie,

The total amount she is paying is

0.33x + $1

= 0.33 × $20.85 + $1

= $6.95 + $1

= $7.96

For Suz

= 0.2x

= 0.2 × $20.85

= $4.17

For Cynthia

= $8.80

Answer:

C

Step-by-step explanation:

To find (g ￮ f)(x), substitute x = f(x) into g(x) , that is

g(2x - 5)

= 3(2x - 5) + 4

= 6x - 15 + 4

= 6x - 11 → C

Answer:

Percentage decrease is 55%.

Step-by-step explanation:

Given the following data;

Original (old) number = 45mL

New number = 20mL

[tex] Percentage \; decrease = \frac{change\; in \;amount}{original\;number} * 100[/tex]

Change in amount = 45 - 20 = 25

Substituting into the equation, we have;

[tex] Percentage \; decrease = \frac{25}{45} * 100[/tex]

[tex] Percentage \; decrease = 0.55 * 100[/tex]

[tex] Percentage \; decrease = 55%[/tex]

Therefore, the hamster’s intake of water decreased by 55%.

Complete question is;

Mr. Stein receives a water bill from city hall. He notices that the city charges $50 for fire and sewer service and $3 for every 1000 gallons of water used. Mr. Stein wants to construct a model describing the relationship between the cost of his water bill and the amount of water he uses.

Which statement best describes the model that Mr. Stein should create?

A. Mr. Stein should use a linear model, since the water bill changes at a constant rate relative to the amount

of water he uses.

B. Mr. Stein should use an exponential model, since the water bill changes at a constant rate relative to the amount of water he uses.

C. Mr. Stein should use a linear model, since the water bill changes at a constant percent rate relative to the amount of water he uses.

D. Mr. Stein should use an exponential model, since the water bill changes at a constant percent rate relative to the amount of water he uses.

Answer:

Option A: Mr. Stein should use a linear model, since the water bill changes at a constant rate relative to the amount

of water he uses.

Step-by-step explanation:

We are told that the city charges $50 for fire and sewer service and $3 for every 1000 gallons of water used.

Since there's a fixed charge of $50 for fire and sewer service and also that the city charges $3 for every 1000 gallons of water used. It means that there is a constant rate of charge for every 1000 gallons used.

It means that the bill he gets depends on the rate of water he consumes.

Thus, stein should use a linear model because the water bill changes at a constant rate relative to the water he consumes.
