Step-by-step explanation:
how i think this question is
13+ -y
y=6
= 13 + -6
=7
therefore the answer is 7
6 X 89 =6 x (80 + 9) = (6 x 80)+ (6x9)=480+54=534
Answer:
-2+2
Step-by-step explanation:
Since we have the value of x, 3+2, we can plug that value into the new equation.
We would recieve (3+2-1)/3+2
Which could simplify to -2+2
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
The average speed would be 53 miles per hour, hope this helped, if you need me to explain then here is the way, so all you do is divide 265 by 5 and what I did to help make it faster was split 265 into 250 and 15 so 250 divided by 5 is 50 and 15 divided by 5 is 3 so 50 + 3 = 53!
