In AUVW, w = 690 inches, ZW=79° and nearest 10th of an inch.

Answer: the number is -16

Step-by-step explanation: if you add 17 to -49, you will get -32. you do this because it is 17 less than NOT more than. that would be called inverse operations. then, you divide that number by 2 to get -16. again, you use inverse operations because you are going backwards to try and find the number.

Answer: -16

Step-by-step explanation: So, to solve, we should write an equation. It should look like this:

2x - 17 = -49

So, using inverse operations, we would add 17 to - 49, which is -32, then divide that by 2, which would be -16. I hope this helped!

P.S. our new equation would look like 2(16) - 17 = -49

32-17 = 49

32 + -17 = 49

49 = 49

It checks out.

The probability of tossing 10 tails in a row is  [tex]\frac{1}{1024}[/tex]

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

Given that,

When a fair coin is tossed 10 times, the sample size (n) is:

n = [tex]2^{10}[/tex]

This is so because a fair coin has 2 sides.

So, we have:

n = 1024

There is only one occurrence of having 10 tails in a row in the 1024 possible outcomes.

So, the probability is:

P = [tex]\frac{1}{1024}[/tex]

Therefore,

The probability of tossing 10 tails in a row is  [tex]\frac{1}{1024}[/tex]

Given

8 + 3i

Required

Rewrite in trigonometric form.

The trigonometric form of a complex equation is

z = r[cosθ + isinθ]

Let a = 3 and b = 8

Where

r is calculated by

r² = b² + a²

And

θ is calculated by

θ = arctan(a/b)

Substituting 3 for a and 8 for b

r² = a² + b² becomes

r² = 3² + 8²

r² = 9 + 64

r² = 73

√r² = √73

r = √73

r = 8.544

Calculating θ

θ = arctan(a/b) becomes

Given a rectangular pool of  35-foot by 20-foot

area of pool = 35 x 20 = 700 sq. foot

and to built a patio around pool of equal width,

budget of patio of $40,200 all amount to be used,

Option 1: Surround the pool with a concrete band of equal width on all sides. The concrete costs $50 per square foot.

the area covered by amount is 40200/50 = 804

let width of patio be x

new length = 35 + x and new breadth = 20 + x

area covered by patio = new area including width - area of pool

new area including width = area covered by patio +  area of pool

new area including width = 804 + 700 = 1504

1504 =  (35 + x)(20 + x )

1504 = x² + 35x + 20x + 700

x² + 55x - 804 = 0

solving the equation by quadratic formula

x = (-b ± [tex]\sqrt{b^{2} - 4ac }[/tex])/ 2a

where a = 1, b = 55, and c = -804

x = (-55 ± [tex]\sqrt{(55)^{2} - 4*1*(-804) }[/tex])/2

x = (-55 ± √(3025 + 3216))/2

x = (-55 ± 79)/2

taking positive values

x = (-55 + 79)/2 = 12

new length = 35 + 12 = 47 foot

new breadth = 20 + 12 = 32 foot

area covered by patio = (47x32) - (35x20)

area covered by patio = 804 sq. foot

and cost will be 804 x 50 = $40,200

for option 2:  Surround the pool with a tile band of equal width on all sides. The tile costs $80 for each square foot tile.

area for patio = 40200/80 = 502.5

since the area is in fraction the cost will come in approximation.

Answer: To calculate the length of a loan, you need to know the total cost of the loan, the monthly payment amount, and the interest rate. In this case, the total cost of the car is $16,000, the monthly payment amount is $250, and the interest rate is 7.3%.

First, you need to calculate the total interest that will be paid on the loan. This can be done by multiplying the total cost of the loan by the interest rate, and then dividing by 100 to convert the result to a percentage. In this case, the total interest paid would be $16,000 * 7.3 / 100 = $1,168.

Next, you need to subtract the total interest from the total cost of the loan to find the total amount of the loan that will be used to pay for the car. In this case, the total amount of the loan used to pay for the car would be $16,000 - $1,168 = $14,832.

Finally, you can use this total amount and the monthly payment amount to calculate the length of the loan by dividing the total amount by the monthly payment amount. In this case, the length of the loan would be $14,832 / $250 = 59.32 months, or just over four years. The answer is 59.32 months.

The present p value which have to be invest in future is $7619.05 at simple interest rate r.

Simple Interest:

Simple interest (S.I) is a method of calculating the amount of interest on a specific amount of money.

The simple interest formula helps determine the amount of interest given a principal, interest rate, and term.

The formula for simple interest is:

SI = PTR/100

where SI = simple interest

P = principal

R = interest rate (percentage)

T = term (years)

For calculating total amount

             Amount (A) = principal Book (P) + Interest (I)

where

Amount (A) is the total amount repaid at the end of the borrowed period.

The simple interest total amount formula can also be written as:

                                    A = P(1 + RT)

where

A = Total amount after specified period

P = Principal or original loan amount

R = Interest rate (annual)

T = Time (annual )

According to the Question:

Simple interest: I = PTR            ---------------------------- (1)

Future amount : A = p + I = p + PTR         ------------------ (2)

Given that:

r = 10% = 0.1

t = 6 months = 0.5 year

A = future amount = 8000

Now,

8000 = p + p (. 1)(0.5)

⇒ 8000 = 1.05 p

⇒ p = 8000/1.05

⇒ p = $ 7,619.05

Now,

Putting the value of p in equation (2)
