The area of Circle is 15∧2*π

Hence option A is correct.

According to the question the diameter of circle is 30 meters

we know,

diameter = radius*2

by using this we can say that the radius of the circle is 30/2

that is  R = 15 meters

now According to the formula

Area of Circle = R*R*π

Putting the value of R into the formula by Substitution method

Area of circle = 15*15*π

hence by this we can say that,

Area of circle = 15∧2*π

[tex] \sf \large \: x=15[/tex]

Step-by-step explanation:

Let's solve your equation step-by-step.

2x/5+1=7

Step 1: Simplify both sides of the equation.

2/5x+1=7

Step 2: Subtract 1 from both sides.

2/5x+1−1=7−1

2/5x=6

Step 3: Multiply both sides by 5/2.

(5/2)*(2/5x)=(5/2)*(6)

x=15

The equation of the tangent line to the graph is equal to y = 0.

A line is tangent to a function if and only if the function meets the curve only in one point. The slope of the tangent line can be found by using the first derivative of the curve and the y-intercept is determined from the slope-intercept form of the equation of the line. First, determine the slope of the tangent line:

f'(x) = 12 · x

f'(0) = 12 · 0

f'(0) = 0

Second, find the intercept of the equation of the line:

y = 6 · 0²

y = 0

b = y - m · x

b = 0 - 0 · 0

b = 0

Then, the equation of the tangent line to the graph is equal to y = 0.

If we are borrowing $10840 to buy a car and repaying it in 6 years (or 72 months) , our monthly payment will be $150.55 or rounded of $200.

As per the question statement, we are borrowing $10840 to buy a car and repaying it in 6 years (or 72 months) , what will be the estimate monthly payment by rounding off to the nearest hundred dollars

First we are supposed to find the monthly payment then we can round it off to the nearest hundred dollars.

Total loan borrowed = $10840

Time taken to pay it off = 6 years or 72 months,

Payment to be made per month = [tex]\frac{10840}{72} \\ 150.5556[/tex]

Therefore [tex]150.5556[/tex] dollars is to be paid every month for 72 months.

After rounding off to the nearest hundred dollars we will get $200.

Hence we are supposed to pay approximately $200 every month for 72 months.

The number of cars should be 100 and that of bus be 0.

x is the number of cars and y is the number of buses.

Area: 6x + 30y <= 600 simplifies to x + 5y <= 100

Total money collected: 2.50x + 7.50 y …..this is what you want to maximize

OR you want to maximize 2.50 (x+ 3 y)

OR you want to maximize (x+3y)

Replacing the value of x from the Area equation in the above price, we get

100 - 5y + 3y is the maximum amount you can collect

So you want to maximize 100 - 2y. This happens when y is 0.

When y is 0; x will be 100 and you will collect 250.

It measures the distance of a point x to the origin.

For this problem, the function is:

d(t) = 1/3|t - 60|.

The d-intercept is given by:

d(0) = 1/3|-60| = 20.

Hence: The cyclist starts 20 kilometers from the station.

The t-intercept is found as follows:

1/3|t - 60| = 0

t - 60 = 0

t = 60.

The equation for the average cost function C   [tex]= \frac{0.00048(x - 200)^{3} + 246840 }{x}[/tex]

When a company creates products or services, it is required to pay production-related expenses. Some of these expenses are cyclical and alter as the output does. Expenditures that alter when production changes include things like raw materials, labor, and utility costs. These are referred to as variables. Other expenses are set, such as rent and insurance payments. These fixed expenses do not alter with changes in output.

The sum of the fixed and variable costs is the total cost.

Total Cost = Variable Cost + Fixed Cost

Now as per the question the cost equation is :

[tex]= \frac{C(x)}{x} = \frac{0.00048(x - 200)^{3} + 246840}{x}[/tex]

In the fields of finance and economics, interest is the payment made at a set rate by a borrower or deposit-taking financial institution to a lender or depositor in excess of the principal amount (the amount borrowed).  It is not the same as a fee that the borrower might pay to the lender or another entity. Interest advance, but rather on a pro-rata basis as a share of the reward received by risk-taking business people when revenue is earned that exceeds all costs.

For Interest, a customer who borrows money from a bank typically pays interest on it, so they pay the bank more than they borrowed; likewise, a customer who earns interest on their savings may withdraw more than they originally put. When it comes to savings, the bank serves as the borrower while the consumer serves as the lender.

Answer: x = -14, y = -13

Step-by-step explanation:

As stated by the question, we can use a system of equations to help us solve.

First, the difference between two numbers (x and y) is -1. The difference represents subtraction.

     x - y = -1

Next, the sum of the numbers (x and y) is -27. The sum represents addition.

     x + y = -27

Now, we can solve this system. We will graph both of the equations. The point of intersection is the solution, see attached. This gives us an answer of x = -14 and y = -13.

     x - y = -1

     x + y = -27

The compound interest earned by Jamaal after a year is $4174.30.

The formula for finding the compound interest is;

CI = p( 1 + r/n)∧nt

where p is the principal amount = $4100.

r is the rate of interest = 1.8% = 0.018.

t is the total time in years = 1 year.

n is the number of time interest given = 4 times.

Put the values;

CI = 4100( 1 + 0.018/4)∧4(1)

CI = 4100×1.018

CI = 4174.30

Thus, the amount of compound interest earned by Jamaal earned after an year is $4174.30.

Step-by-step explanation:

First, split the figure into 3 rectangles and label the sides so that it is easier to work with.

Then you have to find the unknown values: HG and AH.

HG: Since AB=7 and AB is the longest horizontal side; we know that HG+EF+CD=AB=7. Plugging in the known values: HG+3+1=7 => HG+4=7. Therefore, HG=3 because 3+4=7.

AH: BC and FG are the corresponding sides to AH so AH+FG=BC. Plugging in the known values: AH+1=3. Therefore, AH is 2 because 2+1=3.

Now you have to use the perimeter of rectangle formula which is P=2(L+w) for the 3 rectangles.

Rectangle 1: 2(3+2)=10

Rectangle 2: 2(3+1)=8

Rectangle 3: 2(3+1)=8

Add them all up to find the total perimeter: 10+8+8=26.

The standard deviation would be about the same, perhaps a little smaller.

For this problem, we have that an observation of 55 has a difference squared of 1 with the mean, which is less than the variance of 7² = 49, hence the mean of the differences squared would suffer a small decay(small due to the sample size), and would the standard deviation, hence the correct option is given by:
