The standard formula for the circumference (C) of a circle in terms of its diameter (d) is ...
... C = π·d
Answer:
$50 and
$30
Step-by-step explanation:
Question 1. Principal = $500
Rate = 5%
Time = 2yesrs
Interest = PRT /100
= 500 x 5 x 2 /100
= 5000/100
= $50
Interest = PRT/100
Principal P =$500
Rate = 3%
Time = 2 years
Therefore, interest =
500 x 3 x 2 /100
= 3000/100
= $30
Answer:
10.7 m
Step-by-step explanation:
Given that,
The speed of a sound wave, v = 6,420 m/s
The frequency of the wave, f = 600 Hz
We need to find the wavelength of the wave. We can find it using the below relation as follows :
So, the wavelength of the sound wave is equal to 10.7 m.

Answer:
100feet
Step-by-step explanation:
Given the height reached by a dolphin expressed by the equation is h = -16t^2 + 80t. At maximum height, the velocity is zero, hence;
v(t) = dh/dt = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32
t = 2.5secs
Substitute t = 2.5 into the height formula h = -16t^2 + 80t
h = -16(2.5)^2 + 80(2.5)
h = -100+200
h = 100feet
Hence the maximum height the dolphin jumps is 100feet
