Answer:
The answer is below
Step-by-step explanation:
Given the function as:
f(x)=5sin(πx / 15)+180,
a) The angular frequency (ω) = 2π * frequency
but ω = π/15, hence:
π/15 = 2π * frequency
frequency = (π/15)/2π
frequency = 1/30 hertz
Period (T) = 1/frequency = 1/(1/30) = 30 seconds
b) The period is 30 seconds. This means that it reaches the maximum temperature every 30 seconds.
In one hour (3600 s), the number of times the function reaches a maximum temperature = 3600 s / 30 s = 120
Answer:
Step-by-step explanation:
300-124= 176
176/13 = $13.50 per week
I think yes he did in ball rolling in throw the ball 5_t+7t. yes maybe in be ball player in won
8x + 3y = 20.50
-
4x+5y=22.50
=
4x-2y=-2, so you have to divide each number by 2, then
2x-y=-1, so
-y=-1-2x /-1, y=1+2x, then replace it with one original equation like the first one for instance:
8x+3(1+2x)=20.50, then
8x+3+6x=20.50, then
14x=20.50-3
14x=17.5
x=1.25, then solve y:\
y=1+2*(1.25)
y=1+2.5
y=3.5,
So answer is x=1.25, and y=3.5
Answer:
7/16
Step-by-step explanation:
assume she had 8/8 units of sea shells, she then left 1/8 at home
so: 8/8-1/8=7/8
so she has 7/8 units of shells still at home
and she gives half to her friend
so: 7/8*1/2=7/16
She gave 7/16 of the original amount of shells she had to her friend
