Plz help I’m getting timed

I will assume that we want to find the function that predicts the value of the car after x years, which likely is an exponential decay.

The function is: f(x) = $25,000*(0.85)^x

And the graph can be seen at the end of the answer.

We know that the value of the car decreases by 15% each year, then we can model this with an exponential decay.

The general exponential decay is given by:

f(x) = A*(1 - r)^x

Where:

A is the initial value, then we have A  = $25,000

x is the variable, in this case, would represent time in years.

r is the rate of decay, in this case, is the quotient between the percentage that decreases and 100%, so we will get: r = 15%/100% = 0.15

Then the exponential equation is:

f(x) = $25,000*(1 - 0.15)^x

     = $25,000*(0.85)^x

This is the function that models the value of the car after x years, the graph can be seen below.

Answer:

x=2

Step-by-step explanation:

26 divided by 13 is 2

Answer:

For your first question, the solution is x> -12

Step-by-step explanation:

First, expand 2(-3x+1), writing it as -6x+2

Next, subtract both sides by 2;

-6x + 2 - 2 < -5x + 14 - 2

Then, we simplify;

-6x < -5x + 12

Next, add both sides to 5x;

-6x + 5x < -5x + 12 + 5x

Simplify;

-x<12

Then, multiply both sides by -1, using reverse of inequality;

(-x)(-1)>12(-1)

Finally, simplify;

x>-12

Answer:

The answer to your second question is x is greater than or equal to -12.

Step-by-step explanation:

First, multiply both sides by -1, reversing the inequality;

(-2(3x+15))(-1) greater than or equal to 42(-1)

Next, simplify;

2(3x+15) greater than or equal to -42

Then, divide 2 from both sides;

2(3x+15/2 greater than or equal to -42/2

Next, simplify;

3x + 15 greater than or equal to -21

Then, we subtract both sides by 15;

3x+15-15 greater than or equal to -21-15

Simplify;

3x greater than or equal to -36

Next, divide 3 from both sides;

3x/3 greater than or equal to -36/3

Finally, simplify;

x greater than or equal to -12

Answer:

$5.08

Step-by-step explanation:

Step one:

given data

We are told that a credit card company applies a 6% fee on all transactions under $10

since the cost of coffee bellow $10 that is $4.80, the 6% fee is applicable

so

=6% of 4.80

=6/100*4.80

=0.06*4.8

=$0.288

Step two:

the total fee will be

=0.288+4.80

= $5.08

Answer:

129

Step-by-step explanation:

The sum of all angles in any quadrilateral is 360°

so, you can make the following equation:

71 + 48 + 112 + x = 360

231 + x = 360

Subtract 231 from both sides of the equation

231 + x - 231 = 360 - 231

x = 360 - 231

x = 129

Step-by-step explanation:

The given image is a trapezium. A trapezium is a quadilateral. Hence , it's sum of angles is 360°

To solve for x ;

[tex]71° + 48° + 112 ° + x° = 360° \\ 231 + x = 360 \\ x = 360 - 231 \\ x = 129[/tex]

Answer:

The probability is 0.0442

Step-by-step explanation:

If they all come from the same class, what it means is that we select 4 sophomores or , 4 juniors or 4 seniors

When we have or, it means we are to add each possible probability scenarios

The total number from which we want to select from is;

5 + 11 + 13 = 29

So the probability will be;

5C4/29C4 or 11C4/29C4 or 13C4/29C4

= 5C4/29C4 + 11C4/29C4 + 13C4/29C4

=0.0442

c=?

Pythagorean Theorem:

For a right-angled triangle with sides a and b the hypotenuse c

[tex]c=\sqrt{a^2+b^2}[/tex]

[tex]a=68[/tex]

[tex]b=51[/tex]

[tex]c=\sqrt{68^2+51^2}[/tex]

Answer: See explanation

Step-by-step explanation:

Here is the complete question:

A museum requires a minimum number of chaperones proportional to the number of students on a field trip. The museum requires a minimum of 3 chaperones for a field trip with 24 students. Which of the following could be combinations of values for the students and the minimum number of chaperones the museum requires? Choose 2 answers.

A. Students: 72

Minimum of chaperones: 9

B. Students: 16

Minimum of chaperones: 2

C. Students: 60

Minimum of chaperones: 6

D. Students: 45

Minimum of chaperones: 5

E. Students: 40

Minimum of chaperones: 8

Since the museum requires a minimum of 3 chaperones for a field trip with 24 students. This means that there will be 24/3 = 8 students per chaperone.

We then divide the number of students given in the question by the number of chaperone to know our answers. This. Will be:

Students: 72

Minimum of chaperones: 9

This will be: 72/9 = 8

Therefore, this is correct.

B. Students: 16

Minimum of chaperones: 2

This will be: 16/2 = 8

This is correct

C. Students: 60

Minimum of chaperones: 6

This will be: = 60/6 = 10.

Therefore, this is wrong

D. Students: 45

Minimum of chaperones: 5

This will be 45/5 = 9

Therefore, this is wrong.

E. Students: 40

Minimum of chaperones: 8

This will be: 40/5 = 8.

Therefore, this is wrong.

Therefore, options A and B are correct.
