Answer:
Step-by-step explanation:
A = 9
chord length c = 18
height h = 4
r = (c²+4h²)/(8h) = 12.125
Answer:
C and D
Step-by-step explanation:
Use Pythagorean theorem to test
a^2 + b^2 = c^2 ? a and b are the shorter two sides c = longest side
Doing this for each data set shows C and D ARE rt triangles
2 x 2 x 3 x 3
This is really easy to search up btw
Answer:
320,000
Step-by-step explanation:
Answer:
5.50 years
Step-by-step explanation:
A = P
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
3178 = 2000(1+.086/2)^2t
t = 5.499904413
