Find the value of sin² R
1 answer:
If the hypotenuse of PQR triangle is 5 and perpendicular is ,then value of sin²R is 2/25.
Given that the hypotenuse is 5 and perpendicular is .
We are required to find the value of sin²R.
Trigonometric ratios are basically the ratios of the sides of the right angled triangle.
Sin is the ratio of perpendicular and hypotenuse of the right angled triangle. We can easily find the value of sin²R with the help of ratio of perpendicular and hypotenuse.
sin R=PQ/PR
sin R=/5
Squaring both sides,
sin² R=/
sin²R=2/25
Hence if the hypotenuse is 5 and perpendicular is ,then value of sin²R is 2/25.

Answer:
a) 0.5198 computers per household
b) 0.01153 computers
Step-by-step explanation:
Given:
number of computers in a home,
q = 0.3458 ln x - 3.045 ; 10,000 ≤ x ≤ 125,000
here x is mean household income
mean income = $30,000
increasing rate, = $1,000
Now,
a) computers per household are
since,
mean income of $30,000 lies in the range of 10,000 ≤ x ≤ 125,000
thus,
q = 0.3458 ln(30,000) - 3.045
or
q = 0.5198 computers per household
b) Rate of increase in computers i.e
=
or
on substituting the values, we get
or
= 0.01153 computers
