Answer:

f(9) = 50

f(-10) = -64

Step-by-step explanation:

Given the function

f(x) = 6x - 4

f(9) = 6(9)-4

f(9) = 54-4

f(9) = 50

b)f(-10)

Answer:

a) ∠XWY = 53°

b) ∠XZY = 106°

Step-by-step explanation:

The relationship between the central angle and the arc length is that they're equal. So, if arc XY = 106° this means that ∠XZY = 106°.

The relationship between the central angle ∠XZY and the inscribed angle ∠XWY is that the inscribed angle is half the value of the central one.

So, ∠XWY= ∠XZY/2 = 106/2 = 53

Results:

∠XWY = 53°

∠XZY = 106°

the value of P(B) = 1/3

Step By Step Explaination:

If A and B are two independent events, then P(A and B)=P(A) x P(B)  (i)

Put all values in (i), we get

1/6= 1/2  x P(B)

P (B) = 2/6

P(B) = 1/3

Hence The Value of P(B) = 1/3.

Akira and Hideo are twins with different jobs. Akira earns five-eighths of what Hideo earns, but Akira’s expenses are half of Hideo’s. Akira ends up saving 40% of his income. What percentage of his income does Hideo save?

Answers

9514 1404 393

Answer:

  25%

Step-by-step explanation:

Apparently, we're to assume that anything not spent is saved.

Let Hideo's income be 1. Then Akira's income is 5/8. Akira's expenses are 60% = 3/5 of that value, so ...

  Akira's expenses = (3/5)(5/8) = 3/8  . . . . . of Hideo's income

Hideo's expenses are twice this amount, so ...

  Hideo's expenses = (2)(3/8) = 3/4 . . . . . of Hideo's income

That means Hideo saves 1 -3/4 = 1/4 = 25/100 = 25% of his income.

Hideo saves 25% of his income.

You have $3,000 in savings account that pays 2.5% interest, compounded monthly. What is future value in 4 years?

Answers

Answer:

[tex]\$4453.52[/tex]

Step-by-step explanation:

Principal amount (P) = $3,000

Rate of interest (R) = 2.5%

Time period (T) = 4 years

Future value in 4 years = [tex]P(1+\frac{R}{100})^{4T}[/tex]

Jamal drives 3 times the hours that Danielle does. Jamal and Danielle drive for a total of 8 hours. How long did each person drive?

Answers

Answer: Danielle drive for 2 hours

Jamal drives for 2 × 3 = 6 hours

Step-by-step explanation:

Let the number of hours that Danielle used in driving to be represented by x.

Since Jamal drives 3 times the hours that Danielle does. This will be:

= 3 × x = 3x

Since Jamal and Danielle drive for a total of 8 hours. This can be formed into a equation as:

x + 3x = 8

4x = 8

x = 8/4

x = 2

Danielle drive for 2 hours

Jamal drives for 2 × 3 = 6 hours

OK SO I NEED HELP WITH THIS:

My cousin Throckmorton is in a bind. He owes $10000 on a credit card. He can only afford to make $250 payments every month. Unfortunately, since he missed an earlier payment, he is now stuck with the penalty APR of 28%..


Throckmorton makes his payments on time for the next two years.


g) How much total did throckmorteon pay towards his credit card?

h) How much does Throckmorton still owe on the credit card?

i) How much of his money went towards interest?


Hint: i would make a chart.
i barley started on the chart so i dont know what to do

Answers

Answer:

  g) $6000 ($528.18 to principal)

  h) $9,471.82

  i) $5471.82

Step-by-step explanation:

You can make a chart, as you have started. Such a chart is often referred to as an amortization schedule. The basic idea would be to show how each payment is distributed to interest and principal. The attached shows such a spreadsheet (with a few rows hidden). It is described in more detail below.

__

g) The total amount paid is 24 payments of $250 each, so $6000. These payments reduced his amount owed by $528.18. (We don't know if "toward his credit card" means "to the creditor" or "to pay his debt".)

__

h) The amount still owed is $9,471.82 (the ending balance after the 24th payment)

__

i) $5,471.82 went toward interest.

_____

Spreadsheet details

The first "Beg Bal" is the $10,000 owed. Each one after that is copied from the "New Bal" cell on the previous line.

Each "to interest" quantity is the product of the beginning balance and the monthly interest rate. The cell reference to the interest rate needs to be an absolute reference, so it remains the same when copying the formula to other cells.

The "to Principal" amount is the difference between the payment amount and the amount "to interest." The reference to the payment amount cell also must be an absolute reference.

The "End Bal" amount is the difference between the "Beg Bal" and the amount "to Principal".

As you can see, the payment math is not difficult. There is one multiplication (by the interest rate) and the rest is subtraction.

Note that the numbers in this spreadsheet are rounded by the display. In a real payment situation, the interest due amount would be rounded to the penny before being used in other calculations. The way we have done it will result in a few cents difference in the ending balance from the value if the interest were actually rounded at each step.

A) $91.83
B) $67.87
C) $11.98
D) $94.85​

Answers

Answer:

the Smith family pay for the meal = $ 36.39

Step-by-step explanation:

The Smith family went out to dinner . The price of the meal was $ 29.85 .

The sales tax was 6 % of the price of the meal .

LEts find sales tax amount sales tax amount = price of meal *

sales tax 6 % ( 0.06 ) = 29.85 * 0.06 = 1.791 sales tax amount = 1.791

Price of the mean with sales tax = 29.85 + 1.791 = 31.641

The tip was 15 % of the meal and the sales tax now we find out tip amount for 31.641 15 % is 15 / 100 = 0.15

Tip amount = 31.641 * 0.15 = 4.74615

Now we add the top amount with 31.641 31.641+ 4.74615 = 36.38715

the Smith family pay for the meal = $ 36.39
