The answer is .42%
Explained
I / PT = R
I = The amount of interest paid
P = The amount paid before adding interest
T = The time (weeks, months, years)
R = Interest Rate (must move 2 decimal place to the right)
A acute angle is always less than 90 degrees. So the answer is A.
Answer:
80 cm
Step-by-step explanation:
5 points in a star, each point has a perimeter of 16,
16 x 5 = 80
or just legit add all the 8's

Answer: 195.5 or 12 7/32
Step-by-step explanation:
There is no letter tetha in the table so I use α instead. However it is not sence to final result.
The expression is:
(sinα+cosα)/(cosα*(1-cosα))
Lets divide the nominator and denominator by cosα
(sinα/cosα+cosα/cosα)/(cosα*(1-cosα)/cosα)= (tanα+1)/(1-cosα)=
=(8/15+1)/(1-cosα)= 23/(15*(1-cosα)) (1)
As known cos²α=1-sin²α (divide by cos²α both sides of equation)
cos²a/cos²α=1/cos²α-sin²α/cos²α
1=1/cos²α-tg²α
1/cos²α=1+tg²α
cos²α=1/(1+tg²α)
cosα=sqrt(1/(1+tg²α))= +-sqrt(1/(1+64/225))=+-sqrt(225/(225+64))=
=+-sqrt(225/289)=+-15/17 (2)
Substitute in (1) cosα by (2):
1st use cosα=15/17
1) 23/(15*(1-cosα)) =23/(15*(1-15/17))= 23*17/2=195.5
2-nd use cosα=-15/17
2)23/(15*(1-cosα)) =23/(15*(1+15/17))= 23*17/32=12 7/32
Hello from MrBillDoesMath!
Answer:
Slope = 4/5
Discussion:
Slope = (change in y) / (change in x)
Slope =
(1-5)/(0-5) =
-4/-5 =
4/5
Thank you,
MrB
