Answer:

Values for y are y = 52 or y = -48

Step-by-step explanation:

No diagram was provided but the question had enough information to be answered

Since the x coordinates of both barn and well are the same, it means the well is either vertically north of the barn or vertically south.

Therefore y can be either 2 + 50 = 52 giving (-1, 52) as one coordinate

Also y can be 2 - 50 = -48 giving (-1, -48) as another coordinate

Step-by-step explanation:

The required radian measure of the central angle theta is  is 0.872 radians or 0.9 radian.

To find the radian measure of the central angle that intercepts an arc of length 10 feet, we can use the formula for the length of an arc:

Arc Length = Central Angle * Radius

where the central angle is measured in radians.

So, we can write:

10 = Theta * 13

Dividing both sides by 13:

10/13 = Theta

Finally, to convert from degrees to radians,

Radian Measure = (Degree Measure) * (Pi / 180)

So, the radian measure of the central angle is:

Theta = (10/13) * (Pi / 180) = 0.872 radians

Thus, required measurement of angle is 0.872 radians or 0.9 radian.

[tex]\textrm{System A has \boxed{2} real solutions}\\\\\textrm{System B has \boxed{0} real solutions}\\\\\textrm{System C has \boxed{1} real solution}\\[/tex]

Step-by-step explanation:

For a quadratic equation of the form ax² + bx + c = 0

if b² - 4ac > 0 the system will have 2 real roots
if b² -4ac < 0, the system will have 2 imaginary roots(0 real solutions)

if b² -4ac = 0, the system will have exactly one real solution

System A solutions

[tex]x^2 + y^2 = 17\cdots\cdots (1)\\\\y = -\dfrac{1}{2}x\cdots\cdots (2)[/tex]

From equation (2) we get
x = -2y

Substitute this value for x in (1):

(-2y)² + y² = 17

4y² + y² = 17

5y² = 17

y = ±√(17/5)

Both values of y are real, and since x = -2y,x is also real

System B

The equations are:

y = x² - 7x + 10  (1)

y = -6x + 5         (2)

Since left side is y for both:
x² -7x + 10 = -6x + 5

Add 6x to both sides

=> x² -7x + 10 + 6x = -6x + 6x + 5

=> x² -x + 10 = 5

Subtract 5 both sides:
x² - x + 10 - 5 = 0

x² - x + 5 = 0

Comparing to the standard form we get
a = 1, b = -1, c = 5

b²- 4ac = (-1)² - (4 · 1 · 5)

= 1 - 20

= -19

Since b² - 4ac is negative, the system has no real roots

System C

y = -2x² + 9      (1)

8x - y = -17       (2)

In equation(2) isolate y by moving 8x to the right and multiplying by -1

=> -y = -8x - 17

=> y = 8x + 17  (3)

Set right sides of (1) = (3) right side

-2x² + 9 = 8x + 17

Move 8x + 17 to left side

=> -2x² + 9 - (8x + 17) = 0
=> -2x² + 9 - 8x - 17 = 0
=> -2x² - 8x - 8 = 0

we have a = -2, b = -8, c = -8

b² - 4ac = (-8)² - (4)(-2)(-8)

= 64 - (64) = 0

Hence this system has 1 real root

The distance between the ships is increasing at a rate of approximately 98.82 km/h at 4:00 PM.

From the question, we have the following parameters that can be used in our computation:

Distance, D = 170 km

Rates = 40 km/h and 30 km/h

Let t be the time elapsed from noon to 4:00 PM

So, we have

t = 4

The distance between the ships to their east-west and north-south distances is represented as

d^2 = (D + rate 1 * t)^2 + (rate 2 * t)^2

So, we have

d^2 = (170 + 40t)^2 + (30t)^2

d^2 = 170^2 + 13600t + 1600t^2 + 900t^2

Differentiate with respect to time (t)

2D d' = 5000t + 13600

So, we have

D d' = 2500t + 6800

Substitute 4 for t

D d' = 16800

So, we have

d' = 16800/D

This gives

d' = 16800/170

d' = 98.82

So the distance between the ships is increasing at a rate of approximately 98.82 km/h at 4:00 PM.

Step-by-step explanation:

The probability of A or B occurring is the sum of the probabilities of A and B occurring, since they are mutually exclusive events.

Mutually exclusive events are events that cannot occur at the same time. In other words, if one event occurs, the other event cannot occur.

Therefore, the probability of A or B is:

P(A or B) = P(A) + P(B)

P(A or B) = 0.03 + 0.34

P(A or B) = 0.37

So, the probability of A or B is 0.37.

The minimum number of books she must sell to make a profit is 2.

In mathematics, the gain from any business operation is referred to as the profit. Every time a shopkeeper sells a product, his goal is to make a profit by getting something from the customer. Basically, he sells the item for more money than it costs.

Given that Anna estimates her revenue equation as R = 6.56x

And her cost equation as C = 10.063 + 1.09x.

To get profit revenue is greater than cost, i.e.

R>C

6.56x > 10.063 + 1.09x

subtract 1.09x from both sides

6.56x - 1.09x > 10.063

Answer: £2,116.10 each month.

Step-by-step explanation:

To calculate the monthly payment, we first need to find the total amount owed after the compound interest has been added. The formula for compound interest is:

A = P * (1 + r/n)^(nt)

where:

A is the amount owed,

P is the initial principal (the cost of the tractor),

r is the annual interest rate,

n is the number of times interest is compounded per year, and

t is the number of years the loan is taken out for.

In this case:

P = £64,950

r = 4% = 0.04

n = 12 (the number of months in a year)

t = 3 (the number of years the loan is taken out for)

Plugging these values into the formula, we find that:

A = £64,950 * (1 + 0.04/12)^(12*3) = £76,079.69

To find the monthly payment, we divide the total amount owed by the number of payments:

Monthly payment = A / 36 = £76,079.69 / 36 = £2,116.10

So you will pay £2,116.10 each month.

Given a discount rate of 0.15, the NPV of these financial movements is therefore $378.73.

Spending that occurs in the normal run of business is included in cash flow from activities. Payroll, the cost of products sold, rent, and utility bills are a few examples of these cash withdrawals. When company activities are extremely seasonal, cash outflows can differ greatly.

Here's how to do the calculation:

We need to determine how many days passed between the first monetary influx of $-1000, which was received on 12/15/2021, and the present day (2/21/2023). It's been 432 days. Using the equation PV = FV / (1 + r)n, we can determine the current value (PV), the future value (FV), the discount rate (r), and the number of times (n). When the numbers are plugged in, we get PV = -1000 / (1 + 0.15)(432/365) = -845.67.

We must determine how many days passed between the second monetary influx of $300, which was received on January 11, 2022. It's been 406 days. We obtain PV = 300 / (1 + 0.15)(406/365) = 246.87 using the same method.

In order to determine the third financial movement, which is a $600 payment received on 4/7/2023, we must determine how many days have passed since that date. It's been 410 days. Using the same method, we get PV = 600 / (1 + 0.15)^(410/365) = 427.81.

We need to figure out how many days passed between the fourth financial transfer, which was $925 and was received on July 15, 2024. It has been 875 days. We obtain PV = 925 / (1 + 0.15)(875/365) = 548.72 using the same method.

Now we can add up the present values of all the cash flows to obtain the NPV:

NPV = -845.67 + 246.87 + 427.81 + 548.72 = 378.73

To find the sample variance, we first need to find the sample mean of the data set. The mean of the data set is (14 + 7 + 10 + 9) / 4 = 10. The variance is the average of the squared differences between each data point and the mean. The sample variance is ((14 - 10)^2 + (7 - 10)^2 + (10 - 10)^2 + (9 - 10)^2) / (4 - 1) = 14.67. The sample standard deviation is the square root of the sample variance, which is 3.83.
