Answer:4(3x +2)
Step-by-step explanation:
The expressions represent the cost, in dollars, for 4 people to go horseback riding for 3 hours each is 4(3x + 2).
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, The total cost to go horseback riding is a dollar per hour plus a $2 fee for renting a helmet.
Let, The number of hours is represented by 'x'.
Therefore, The cost of riding with a helmet is,
= x + 2.
The cost of riding for 3 hours is 3x + 2 and the cost for 4 people is doing the same is, 4(3x + 2).

when you convert 10000 present dollars into future dollars of year 15 if the inflation rate is 77% per year, the result is equal to __________.
Answer:
$125,500
Step-by-step explanation:
From the question we are given the following
Present amount = 10000
Inflation rate = 77%
Time = 15years
Using the simple interest method n
Get the inflation amount after 15years
SI = Principal × Rate ×Time/100
SI = 10000×77×15/100
SI = 100×77×15
SI= $115500
The amount after 15years = Present amount + interest
Amount after 15years = 10000+115500
Amount after 15years = $125500
Hence the required result is equal to $125,500

How do you determine the area under a curve in calculus using integrals or the limit definition of integrals?
Answer:
Please check the explanation.
Step-by-step explanation:
Let us consider
[tex]y = f(x)[/tex]
To find the area under the curve [tex]y = f(x)[/tex] between [tex]x = a[/tex] and [tex]x = b[/tex], all we need is to integrate [tex]y = f(x)[/tex] between the limits of [tex]a[/tex] and [tex]b[/tex].
For example, the area between the curve y = x² - 4 and the x-axis on an interval [2, -2] can be calculated as:
[tex]A=\int _a^b|f\left(x\right)|dx[/tex]
= [tex]\int _{-2}^2\left|x^2-4\right|dx[/tex]
[tex]\mathrm{Apply\:the\:Sum\:Rule}:\quad \int f\left(x\right)\pm g\left(x\right)dx=\int f\left(x\right)dx\pm \int g\left(x\right)dx[/tex]
[tex]=\int _{-2}^2x^2dx-\int _{-2}^24dx[/tex]
solving
[tex]\int _{-2}^2x^2dx[/tex]
[tex]\mathrm{Apply\:the\:Power\:Rule}:\quad \int x^adx=\frac{x^{a+1}}{a+1},\:\quad \:a\ne -1[/tex]
[tex]=\left[\frac{x^{2+1}}{2+1}\right]^2_{-2}[/tex]
[tex]=\left[\frac{x^3}{3}\right]^2_{-2}[/tex]
computing the boundaries
[tex]=\frac{16}{3}[/tex]
Thus,
[tex]\int _{-2}^2x^2dx=\frac{16}{3}[/tex]
similarly solving
[tex]\int _{-2}^24dx[/tex]
[tex]\mathrm{Integral\:of\:a\:constant}:\quad \int adx=ax[/tex]
[tex]=\left[4x\right]^2_{-2}[/tex]
computing the boundaries
[tex]=16[/tex]
Thus,
[tex]\int _{-2}^24dx=16[/tex]
Therefore, the expression becomes
[tex]A=\int _a^b|f\left(x\right)|dx=\int _{-2}^2x^2dx-\int _{-2}^24dx[/tex]
[tex]=\frac{16}{3}-16[/tex]
[tex]=-\frac{32}{3}[/tex]
[tex]=-10.67[/tex] square units
Thus, the area under a curve is -10.67 square units
The area is negative because it is below the x-axis. Please check the attached figure.

Omar shops for a new television. He finds the same television at two different stores priced at $259.99. One store offers a mail-in rebate of $75. At a different store, the television is 30% off the regular price. At which store will Omar receive the better deal? Why?
Answer:
At the second store. Because 30% Of 259.99 is more than 75$.
Step-by-step explanation:
store 1.
259.99 - 75 = 184.90
stode 2.
259.99 * 30% = 78
259.99 - 78 = 181.99
1) Target offers their employees group health
insurance and covers 70% of the cost. If the annual
premium for the insurance is $12,450.00 how much
is deducted from your monthly paycheck?
$311.25 is the amount deducted from the monthly paycheck, if, the annual premium for the insurance is $12,450.00 and target offers their employees group health insurance and covers 70% of the cost.
First, find the amount that the employee contributes to the cost. it can be calculated by multiplying the annual premium by the percentage they pay
$12450.00 x 70%
= $12450 x 70/100
= $8715
Now, subtract the employee's contribution from the total to find the amount that is being taken out of their pay check
12450 - 8715 = - 3735
To find the amount deducted monthly, divide the difference amount by 12
= $3735/12
= $311.25
The amount deducted from monthly paycheck is $311.25

A lifeguard can swim at a speed of 6 feet per second and run at a speed of 10 feet per second. The lifeguard is standing at the edge of a beach, looking at the ocean to the south. The lifeguard sees a drowning child in the ocean 100 feet east (down the shore) and 80 feet south (out at sea). How far should the lifeguard run before they start swimming?
The requried distance run and swam by the lifeguard is 100 - x. and √[x² + 80²] respectively.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The question seems to be incomplete, there must be a figure that illustrates the situation,
Since, as of the given data, he might run x distance less toward the east as of the 100 feet east, and than swim, the distance is given as,
= √[x² + 80²].
And the distance run = 100 - x.
Thus, the requried distance run and swam by the lifeguard is 100 - x. and √[x² + 80²] respectively.

If the measure of angle 1= (6x+25) and the measure of angle 4= (10x-11) find the measure of angle 1
The measure of angle 1 is 79°
Given:
Value of angle 1 = (6x + 25)
Value of angle 4 = (10x - 11)
Find:
The measure of angle 1
Computation:
In the absence of complete question,
Assume;
Angle 1 = Angle 4
So,
6x + 25 = 10x - 11
10x - 6x = 25 + 11
4x = 36
x = 36 / 4
Value of x = 9
By putting value of x in angle 1
Value of angle 1 = (6x + 25)
Value of angle 1 = 6(9) + 25
Value of angle 1 = 54 + 25
Value of angle 1 = 79

Megavolt begins manufacturing evil light bulbs for his latest scheme. To ensure quality, he tests every 100th bulb manufactured, starting with the 42nd. What method is Megavolt use to select his sample?
Answer:
Megavolt used a Systematic sampling method.
Step-by-step explanation:
From the information given:
For every 100th evil light bulbs tested, he starts with the 42nd. This implies that;
The first bulb tested is the 142nd bulb, the second bulb tested is the 242nd...
The sequence is as follows:
142nd, 242nd, 342nd, 442nd, 542nd, 642nd .... etc
From the starting point of manufacturing the evil light bulb, the sequence is derived from sampling where each nth unit is known to be a sample, and this is only feasible in systematic sampling.
