Answer:
10
Step-by-step explanation:
By Pythagoras' Theorem:
16 + r = √(24^2 + r^2)
(16 + r)^2 = 24^2 + r^2
256 + 32r + r^2 = 576 + r^2
32r = 320
r = 10
Answer:
24. 7z^2(2z^3+1)
27. 7t (3t - 2)
30. 3a^2 (a^3-2a+4)
Step-by-step explanation:
You didnt specify what to do so i just assume this is a factorization question.

Answer:
A:B
Step-by-step explanation:
i need numbers or something.
Apply simple interest formula
future value = present value (1+n*rate)
n=number of years
rate = annual interest rate in decimal
Plug in values,
10000=3900(1+0.0783*t)
1+0.0783t=10000/3900
t=(10000/3900-1)/0.0783
=19.98 years.
With compound interest, future value=present value (1+rate/n)^(nt)
n=1,rate=0.0783, future value=10000, present value=3900,
t=log(10000/3900)/log(1.0783)=12.49 years.
