The exponential growth of 16.63% will take approximately 10.80 years to reach a population of 1134

An exponential function is a mathematical function, which is used in many real-world situations. It is mainly used to find the exponential decay or exponential growth or to compute investments, model populations and so on.

Data;

f(x) = P(1 + r)ˣ

x = time

Substituting the values

1134 = 215(1 + 0.1663)^ˣ

x = 10.80

It will take approximately 10.8 years to reach a growth of 1134

I took the test

The equation of a line perpendicular to the line 2x - 5y = 5 is 10x + 4y = 3.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

The product of the slope of perpendicular lines is equals to negative 1.

Therefore, the slope of the equation 2x - 5y = 5.

Hence,

2x - 5y = 5.

2x - 5 = 5y

y = 2 / 5 x  - 1

Therefore, the slope is 2 / 5. Therefore, the slope of the equation will be - 5 / 2.

using

y = - 5 / 2 x + b

Hence, the equation is 10x + 4y = 3.

The percent of the people surveyed were satisfied with the​ car will

be 45%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

Total number of people in a survey of car = 1,500

And, 675 people said they would buy that type of car again.

Now,

Total number of people in a survey of car = 1,500

And, The people surveyed were satisfied with the​ car = 675

Hence, The percent of the people surveyed were satisfied with the​ car is;

= 675 / 1500  x 100

= 0.45 x 100

= 45%

Thus, The percent of the people surveyed were satisfied with the​ car will

The value of x in the second ordered pair is - 0.5 or - 1/2 and that of y in the first ordered pair is 8.

The given ordered pair is (-3,y) and (x,2)

the equation y=-2x+2

In the first step we put the value of x as -3 as given in (-3,y) in the equation y=-2x+2, we get

y=-2(-3)+2

⇒y=6+2

⇒y=8

So the value of y is 8 then the ordered pair will be (-3,8).

Again, in the second step, we put the value of y as 2 as given in (x,2) in the equation y=-2x+2, and we get

The speed of the current is equal to 8 miles per hour.

Mathematically, speed of any physical object can be calculated by using this formula;

Speed = distance/time

Let the variable c represent the speed of the current in miles per hour. Therefore, the downstream and upstream speed relative to the water would be given by this mathematical expression:

Speed downstream = 14 + c.

Speed upstream = 14 - c.

Additionally, the total time would be given by:

Total time = total distance/speed

Time upstream + time downstream = 6.5 hours

33/(14 - c) + 33/(14 + c) = 7.0

Multiplying both sides of the equation by (14 - c)(14 + c), we have:

33(14 + c) + 33(14 - c) = 7.0(14 - c)(14 + c)

462 + 33c + 462 - 33c = 7.0(196 - c²)

924 = 7.0(196 - c²)

Dividing both sides of the equation by 7.0, we have:

132 = 196 - c²

Speed of the current, c² = 196 - 132

Speed of the current, c² = 64

Speed of the current, c = √64

Speed of the current, c = 8 miles per hour.

Step-by-step explanation:

The operating profit for September was $168,418.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Using the given information, we can calculate the following:

Total fixed cost per month.

= Instructor wages + Classroom supplies + Utilities + Campus rent + Insurance + Administrative expenses

= $2,970 + $310 + $1,230 + $4,900 + $2,400 + $4,000

= $15,810

Variable cost per course.

= Cost per course for utilities + Cost per student for administrative expenses

= $65 + $4 = $69

Variable cost per student

= Sales revenue per student - Total variable cost per student

= $890 - $69

= $821

Using the planned number of courses and students, we can calculate the expected revenue:

Expected revenue.

= Planned number of courses x Planned number of students x Sales revenue per student

= 4 x 62 x $890 = $221,120

Using the actual number of courses and students, we can calculate the actual revenue and costs:

Actual revenue

= Actual number of courses x Actual number of students x Sales revenue per student

= 4 x 52 x $890

= $184,640

Total variable cost

= (Variable cost per course x Actual number of courses) + (Variable cost per student x Actual number of students)

= ($69 x 4) + ($4 x 52)

= $412

Total cost

= Total fixed cost + Total variable cost

= $15,810 + $412

= $16,222

Operating profit

= Actual revenue - Total cost

= $184,640 - $16,222

= $168,418

Therefore,

The operating profit for September was $168,418.
