In triangle ABC, mA= 40°, the length of side AB is 7 cm and the length of side BC is 5 cm. Find the measure of angle C using the

Sauron [17]

Answer:

C = 64.145º

Step-by-step explanation:

The Law of Sines is as follows:

$\frac{sinA}{a}$ = $\frac{sinB}{b}$ = $\frac{sinC}{c}$

The problem can be draw as the picture attached.

Now, the values of the sides and angles can be substituted into the Law of Sines, and because all parts are equal, only two are needed:

$\frac{sin40}{5}$ = $\frac{sinC}{7}$

Next, cross-multiply:

7sin40º = 5sinC

Then, divide both sides by 5:

$\frac{7sin40}{5}$ = sinC

Finally, take the inverse sin of the left side and convert into a decimal:

C = $sin^{-1}$ ( $\frac{7sin40}{5}$ )

C = 64.145

How much is 400.00 invested at 9% interest compounded continuously be worth after 3 years

blagie [28]

COMPOUNDED
not simple interest,
compound interest is neat since you earn interest on the interest you earned

ok so what you use is F=Pe^(rt)
F=future or ending amount
P=present amount
e=base of the natural log (some digits are 2.71828182845)
r=rate in decimal
t=time in years

presen amount is 400
rate is 9% or 0.09
time is 3 years

F=400e^(0.09*3)
F=400e^(0.27)
F=523.986
round
F=523.99

Help please? I will mark brainlist..........

krek1111 [17]

Answer:

P(Red)= 8/24=1/3

P(Green)= 4/24=1/6

P(red or white) = 8/24+5/24= 13/24

P(not white nor green)= 24/24-(5/24+4/24)= 15/25

P(all colors except yellow)= 24/24- 7/24= 17/24

P(black)= impossible
