Answer:

3. 9.2 mL; 4. 0.25 mL

Step-by-step explanation:

3. 12 mL syringe

The arrow points to the first division between 9 mL and 10 mL.

There are five divisions, so

5 divisions = 1.0 mL or

1 division = 0.2 mL

The reading is

9.0 mL + 0.2 mL = 9.2 mL

4. 0.5 mL syringe

The arrow points to the fifth division between 0.20 mL and 0.30 mL.

There are 10 divisions, so

10 divisions = 0.10 mL or

1 division = 0.01 mL

5 divisions = 0.05 mL

The reading is

0.20 mL + 0.05 mL = 0.25 mL

Fifteen years ago, you deposited $12,500 into an investment fund. Five years ago, you added an

True [87]

Answer:

a) 8.16%

b) $65,762.50

c) $39,701.07

Step-by-step explanation:

Given:

15 years ago, Initial investment = $12500

5 years ago, Investment = $20000

Nominal interest = 8% semi annually for first 10 years

Interest2= 6.5% compunded annually for last five years

a) for the effective annual interest rate (EAR) in the first 10 years, let's use the formula:

[1+(nominal interest rate/number of compounding periods)]^ number of compounding periods-1

$EAR = [1 + (\frac{0.08}{2})]^2 - 1$

$= (1 + 0.04)^2 - 1$

$= (1.04)^2 - 1$

= 1.0816 - 1

= 0.0816

= 8.16%

The effective annual interesting rate, EAR = 8.16 %

b) To find the amount in my account today.

Let's first find the amount for $12500 for 10 years compounded semi annually

= 12,500 +( 12,500 * 8.160% * 10)

= $ 22,700

Let's also find the amount for $32,500($12,500+$20,000) for 5 Years compoundeed annually

$32,500 + ($32,500 * 6.5% *5)

= $ 43,062.50

Money in account today will be:

$22,700 + $43,062.50

= $65,762.50

c) Let's the amount I should have invested to be X

For first 10 years at 8.160%, we have:

Interest Amount = ( X * 8.160% * 10 ) = 0.8160 X

For next 5 years at 6.5%, we have:

Interest Amount = (X * 6.5% * 5) = 0.325 X

Therefore the total money at the end of 15 Years = 85000

0.8160X + 0.3250X + X = $85,000

= 2.141X = $85,000

X = 85,000/2.141

X = 39,701.074 ≈ $39,700

If I wish to have $85,000 now, I should have invested $39,700 15 years ago

If cosθ =1/3 , then sinθ = _____.

DedPeter [7]

We are given: cos theta = 1/3. Thus, adj side = 1 and hyp = 3. Using the Pythagorean Theorem to find the length of the opposite side, represented by x.

1^2 + opp^2 = 3^2, or 1 + x^2 = 9, or x^2 = 8. Here, x could be either sqrt(8) or -sqrt(8): sqrt(8) if angle theta is in QI, and -sqrt(8) if in QIV.

Thus, the sine of angle theta could be either sqrt(8)/3 or -sqrt(8)/3.
