Answer:
Option D
Step-by-step explanation:
Given that the number of hours of daylight in a city in the northern hemisphere shows periodic behavior over time
Let t be the independent variable and no of hours H(t) be the dependent variable on t.
Maximum H(t) = 14.4 and average =12
Period = 365 days
If we fix a sine curve for this since period is 365, we must have coefficient of t as
So the function H(t) will have sine term as sin 0.017t ... i
Since average = 12, we have
H(t) = 12+a sin 0.017t
for some suitable a.
To find a, use maximum
Maximum is when angle is 90 degrees i.e. when sine value =1
max H(5) = 14.4 = 12+a (1)
a =2.4
Hence correct equation would be'H(t) = 2.4sin(0.017t)+12
OPtion D is right answer.
Answer:
r =
Step-by-step explanation:
In order to make 'q' the independent variable in the equation, you need to solve for 'r'. The dependent variable would be 'r' because it depends on the value of 'q' to be solved. We can solve for 'r' by using inverse operations and completing the same operation on both sides of the equation. Starting with the initial equation and solving for 'r':
-7q + 12r = 3q -4
Add '7q' to both sides: -7q + 7q + 12r = 3q - 4 + 7q or 12r = 10q - 4
Divide all terms by 12: 12r/12 = 10q/12 - 4/12
Simplify: r =
