In which quadrant does the terminal side of the angle 215° lie?

Mathematics
1 answer:
Ivan3 years ago
5 0

1. You got it right.

4π/9 x 180/π = 80°

2. To get a coterminal angle you start with your angle and then you add or subtract 360° (one cycle around the circle).

-123+360+360 = 597°

-123-360 = -483°

3. The angle is 215° from the point (1,0) on the unit circle. The angle 215° is between 180° and 270° so it is in quadrant 3.

vredina [299]

Answer:

5×10⁻²

Step-by-step explanation:

        b.  If the decimal is being moved to the left, the exponent will be positive.

  • Therefore. The answer is 5×10⁻²

Aaron invested $740 in an account paying an interest rate of 5%
vlada-n [284]

The amount of money   Justin would have in his account than Aaron, to the nearest dollar is $0

What is the future value formula for continuous compounding cash flow?

The future value, which is used to determine the worth of this investment of $740 made now in 18 years is as shown below:

FV=PV*e^(rt)

FV=the worth of the investment in 18 years=unknown

PV=the amount invested today=$740

e=mathematical exponential value=2.7182818

r=rate of interest which compounded continuously=5%

t=time of investment in years=18

FV=$740*2.7182818^(5%*18)

FV=$740*2.7182818^(0.90)

FV=$740*2.459603087981220

FV=$1,820.11

Justin:

FV=PV*(1+r/m)^(n*m)

PV=$740

r=5%

m=number of times in a year that interest is compounded=365

m=number of years=18

FV=$740*(1+5%/365)^(18*365)

FV=$1,819.99

difference=$1,820.11-$1,819.99

difference=$0.12($0 to the nearest dollar)
