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.
1) first you multiply each side by -2
1a) that clears the -1/2
x = -12

Step-by-step explanation:
A positive rational is any real number that can be written in the form a/b, where a and b are positive integers. ... A negative rational is any real number that can be written in the form -a/b, where a and b are positive integers.
Answer:
x=20.26
Step-by-step explanation:
tan40°=17/x
x=17/tan40°
x=20.25981107 or 20.26
