josianne had two difference offers (1) 12000 cash and (2) 8000 semiannually for 5 years. assuming 10% compounded semiannualy determine the better offer and find the difference between them

Answers

Answer 1

Total = principal * (1 + (rate / n) ) ^ years * n
where "n" is the number of compounding periods per year
Total = 8,000 * (1 + (.1 / 2)) ^ 5 * 2
Total = 8,000 * (1.05) ^ 10
Total = 8,000 * 1.6288946268
Total = 13,031.16
So, the 8,000 @ 10% compounded semi-annually is the better offer because it pays $1,031.16 more.

4y≤-x+20 divide both side by 4

Based on the correlation coefficient, describe the relationship between time and surface area of the puddle. [Choose the value of the correlation coefficient from −1, −0.99, −0.5, −0.02.] (4 points) Part B: What is the value of the slope of the graph of surface area versus time between 1 and 4 hours, and what does the slope represent? (3 points) Part C: Does the data in the table represent correlation or causation? Explain your answer. (3 points)

Answers

The picture of how the graph looks like is shown in the picture.

Part A. The correlation coefficient, R², is the quantitative evaluation of how the data points are well-fitted to a model. The closer it is to 1, the better. But a R²=1 is very ideal and rare. This can be only true if the points coincides exactly with the given model. Since we can see in the graph that the points are exaclty passed through by the linear model, the correlation coefficient is 1.

Part B. The slope of the graph is measured between two points as Δy/Δx. So, between 1 to 4 hours, the slope is: (85-100)/(4-1) = -5. The slope represents the instantaneous rate of change of surface area with time. It is called instantaneous because the change was only between than interval, not the whole set of data. Also, the negative sign signifies that the trend is decreasing.

Part C. The data represents causation if the time was the cause of the change of the pond's surface area. However, this is not technically true because there might be other factors to be considered like environmental conditions. But, definitely, these data are in correlation because together they show an observable trend.

In parallelogram ABCD, if angle C=110 and angle D=70, what is the sum of the measures of angle A and angle B?

Answers

To solve this problem, we must remember that the sum of interior angle of a polygon is:

Sum of interior angles = (n – 2) * 180˚

So, we can say that:

Sum of interior angles = angle A + angle B + angle C + angle D = (4 – 2) * 180˚

Where,

angle C + angle D = 110 + 70 = 180˚

Therefore substituting this value:

angle A + angle B + 180˚ = 2 * 108˚

angle A + angle B = 360˚ - 180˚

angle A + angle B = 180˚ (answer)

Hence we can also conclude that,

angle A + angle B = angle C + angle D

The answer is 180 degrees because...

angle A + angle B + 180˚ = 2 * 108˚

angle A + angle B = 3

angle A + angle B = 180˚ 60˚ - 180˚

Hope this helps, have a BLESSED and wonderful day! As well as as a safe one! :-)

How many revolutions will a car wheel of diameter 26 in. make as the car travels a distance of one mile? (round your answer to the nearest whole number.)?

Answers

circumference of the wheel = pi*d = 26pi ins = 13pi / 6 feet
there are 8280 feet in 1 mile

The number of revolutions in travelling 1 mile = 5280 * 6
----------- = 776 revs
13 pi

Answer:

776 revolutions per mile

Step-by-step explanation:

First we need to find the Circumference of the wheel.

Formula for circumference = πD

Where D = Diameter of the car wheel = 26 inches

Circumference of the car wheel = π × 26

= 81.68 inches

We have to find, how many inches make 1 mile.

1 mile = 63360 inches.

To determine the number of revolutions a car wheel of diameter 26 inches will travel,

= 63360 inches ÷ circumference of the car wheel

= 63360 inches ÷ 81.68inches

= 775.71 revolutions per mile

To the nearest whole number = 776 revolutions per mile.

A 125-inch pipe is cut into two pieces. one piece is four times the length of the other. find the lengths of the two pieces.

Answers

Final answer:

You can calculate the length of the two pieces of pipe by setting up and solving a simple equation: 'x' stands for the length of the shorter piece, '4x' stands for the length of the longer piece, which will add up to the total length, 125 inches. You will find that 'x' equals 25, meaning the shorter pipe is 25 inches long and the longer one is 100 inches long.

Explanation:

This question revolves around a simple equation in algebra. If we say that the shorter piece of pipe's length is 'x', we know from the problem that the longer piece's length is four times this length, or '4x'. The total length of the pipe, 125 inches, is made up of these two pieces. Therefore, those two lengths must add up to 125 inches.

This gives us the equation 'x + 4x = 125'. Combining like terms gives us '5x = 125'. To find 'x', we then divide both sides of the equation by 5, giving us 'x = 25'. Therefore, the shorter piece of pipe is 25 inches long, and the longer piece, being four times this length, is 100 inches long.

The measure of arc UV is 24° .

What is arc?

An “arc” is a smooth curve joining two endpoints. In general, an arc is one of the portions of a circle. It is basically a part of the circumference of a circle. Arc is a part of a curve.

According to the question

The Triangle formed inside the triangle

with angles 90° , 36° , ∠W

As sum of angle of triangle

99° + 36° + ∠W = 180°

∠W = 180° - 99° - 36°

∠W = 45°

Now,

According to the relation

∠W = [tex]\frac{1}{2}[/tex](arc SP - arc UV)

Arc SP = 94° + 20°

= 114°

so ,

45° = [tex]\frac{1}{2}[/tex]( 114° - arc UV)

90° = 114° - arc UV

arc UV = 114° - 90°

= 24°

Hence, the measure of arc UV is 24° .

What is a constant line?

A general linear equation is given by:

y = a*x + b

Where a is the slope and b is the y-intercept.

We say that a line is a constant line if the slope is equal to zero, so we get:

y = b

This would be graphed as a horizontal line.

A hair-styling salon charges $11.00 for a haircut, and an average of 75 people stop in for haircuts each day. The owner is thinking of increasing the price, and he estimates that every time he raises the price of a haircut by $1.00, the number of people coming in for haircuts will decrease by 3 per day. Which of these functions represents the estimated revenue per day from haircuts as a function of the number of dollars the price of a haircut is raised?

Answers

Final answer:

The estimated daily revenue function, given the described price increase and corresponding customer decrease, can be represented as R(x) = (11 + x)(75 - 3x), where x is the number of dollars by which the price is raised.

Explanation:

The question asks us to find a function that represents the estimated revenue per day from haircuts as a function of the number of dollars the price of a haircut is raised. Initially, the salon charges $11.00 for a haircut with an average of 75 people per day. When the price increases by $1, the number of customers decreases by 3.

Let x represent the number of dollars by which the haircut price is raised. The new price will be $11.00 + x. The number of customers is initially 75, and for each $1 increase, we lose 3 customers, so the new number of customers will be 75 - 3x. The daily revenue, R(x), can be found by multiplying the new price by the new number of customers:

R(x) = (11 + x)(75 - 3x)

This function will give us the estimated daily revenue after increasing the haircut price by x dollars.
