O TRIGONOMETRIC FUNCTIONS

Mathematics
1 answer:
grandymaker [24]3 years ago
5 0

Answer:

r = 22.9 in.

Step-by-step explanation:

Central angle in radians, ∅ = π/4

Length of arc, S = 18 in.

radius (r) = ?

Length of arc, C = r∅

Plug in the values and find r

18 = r*π/4

18 = (πr)/4

Multiply both sides by 4

4*18 = πr

72 = πr

Divide both sides by π

72/π = r

r = 22.9183118

r = 22.9 in. (Nearest tenth)

WINSTONCH [101]

Answer:

The recursive rule for account balance at the beginning of the nth month will be given by b_{1} = 100 and b_{n + 1} = b_{n} + 76 where, n = 1, 2, 3, .....

Step-by-step explanation:

On January 1, 2006, I have $100 in a savings account that earns interest at a rate of 1% per month. On the last day of every month, I deposit $75 in the account, beginning in January.

So, at the end of the month of January, the added amount to the account is $75 and 1% of $100 i.e. 1$.

Then, total $(75 + 1) = $76 is being added at the end of each month.

So, the recursive rule for account balance at the beginning of the nth month will be given by b_{1} = 100 and b_{n + 1} = b_{n} + 76 where, n = 1, 2, 3, ..... (Answer)

A bank account has an initial deposit of $14,000. After 8 years, the bank account
Kamila [148]

Answer:

2.3%

Step-by-step explanation:

18000 = 15000( 1 + i)^8

Divide both sides by 15000

1.2 = (1 + i)^8

Take both sides to the 1/8 power

1.2^(1/8) = 1 + i

1.023051875220463 = 1 + i

Subtract 1 from both sides

i = 0.023051875220463

~ 2.3%

I'm thinking of a number. When I multiply by 8 and add –1, I get –17. What's my number?
frosja888 [35]

Say that you're thinking of number x

You multiply it by 8, and have 8x

You add -1 (i.e., you subtract 1) and have 8x-1

This equals -17, so you have

8x-1=-17

Add 1 to both sides

8x=-16

Divide both sides by 8:

x=-2

So, you were thinking of -2.
