Answer:

[tex]f(x)=600(0.09)^x[/tex]

Step-by-step explanation:

Since f(x) decreases by 9% for every one unit increase in x, it means that f(x) is an exponential decay function. An exponential function is given by:

f(x) = [tex]ab^x[/tex]; where a is the value of f(x) at x = 0, b is the multiplier and is less than 0 for a decay.

Therefore since at x = 0, f(x) = 0. Hence a = 600. Also, b = 9% = 0.09.

The function f(x) can hence be represented as:

[tex]f(x)=600(0.09)^x[/tex]

Answer:

2/7

Step-by-step explanation:

Since the denominators are the same, we need to add the numerators and place it over the common denominator

-4+6 = 2

so

-4/7 + 6/7 = 2/7

Answer:

The tires are spinning at 660.49 revolutions per minute.

Step-by-step explanation:

The speed of the tires (v) is the same that the speed of the car, so to find the angular velocity of the tires we need to use the equation:

[tex] \omega = \frac{v}{r} [/tex]

Where:

r: is the radius of the tires = d/2 = 28 inches/2 = 14 inches

[tex]\omega = \frac{55 mph}{14 inches*\frac{1 mile}{63360 inches}} = 2.49 \cdot 10^{5} \frac{rad}{h}*\frac{1 h}{60 min}*\frac{1 rev}{2\pi rad} = 660.49 rpm[/tex]              

Therefore, the tires are spinning at 660.49 revolutions per minute.

Answer:

Each child ticket cost = $6

Step-by-step explanation:

Joe has = $100

His balance after tickets purchase = $22

Actual amount spent on tickets = $100 - $22 = $78

But,

Each adult ticket cost = $9

Total no of adult = 6

Total amount spent (adults) = $9 x 6 = $54

Balance remaining = $78 - $54 = $24

Amount spent of 4 child tickets = $24

No of children = 4

Therefore,

Amount spent on 1 child (1 ticket),

= $24/4 = $6.

It could be seen that each child ticket cost six dollars.

48+140=188

92+210=302

if you at all it equals 490

Answer:

∠2 = 80°

Step-by-step explanation:

∠1 and ∠2 are supplementary angles (their sum is 180°)

Answer:

36

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

<A+ <B+ <C = 180

2x+6x+2x = 180

10x = 180

Divide by 10

10x/10 = 180/10

x = 18

We want to find <C

<C = 2x

     = 2*18

    = 36

Answer:

12710 license plates

Step-by-step explanation:

Second character = one of 31 emojis

Third character = one of 10 polygons

A license plate consists of 3 characters

Number of 3-character license plates available :

Number of hieroglyphs * Number of emojis * number of polygons

41 * 31 * 10 = 12710 license plates.

f(x) = (cost)x

Answer:

c=s*x

Step-by-step explanation:

C will be the total cost of our family's outing to the soccer game

While x will be the hours

and S will be the soccer game

So s*x will equal the cost

Making c=.

5 because of slope equation

Answer:

This is a ratio table,so therefore there is always a pattern.

Step-by-step explanation:

In order to solve,you have to find the constant in the question,such as 30,40,50,and 60.The constant in this example is 10.When the constant is not even,or the numbers are not even,that's the time you pull out your notebook multiplication chart.Look at the numbers,and see if those numbers are on the chart.If all of them are on the chart,then see if one or both of the multiplicable numbers fall under the category of your variables.If all are under one number,then that number is your answer.

49°+41° = 90°

77*22=    1694                     2*22=44

Step-by-step explanation:

22w + 44 = 77 is the equation which represents the situation and the price of a bottle of water is $1.5.

Two or more expressions with an Equal sign is called as Equation.

Let w be the price of a bottle of water.

The coach is buying 22 bottles of water and 22 energy bars, which cost a total of $77.

The cost of 22 energy bars is $2 x 22 = $44.

So the total cost of 22 bottles of water and 22 energy bars is:

22w + 44 = 77

We can simplify this equation by first subtracting 44 from both sides:

22w = 33

Then, we can solve for w by dividing both sides by 22:

w = 1.5

Therefore, 22w + 44 = 77 is the equation which represents the situation and the price of a bottle of water is $1.5.
