Answer: 2.1 tan 37 = x/2.1 * 2.1. 2.1 tan 37 = x. 1.582463505 =x. To the nearest tenth. 1.6 =x.
Step-by-step explanation:
The diameter of the coaster is 5 cm.
Step-by-step explanation:
Given,
The area of the circle = 19.63 sq inch
To find the diameter, we need to find the radius
Formula
The area of a circle with radius(r) = π
sq cm
According to the problem,
π
= 19.63
or,
= 
= 6.2459
or, r =
= 2.499 (approx)
= 2.5 cm
Hence the diameter of the circle = 2 × 2.5 cm = 5 cm
To solve the equation: sqrt(x) = m
Take the square of both sides to have (sqrt(x))^2 = m^2
=> x = m^2
Answer:
x^-2
Step-by-step explanation:
(x*x*x)/(x*x*x*x*x)
1/x*x
1/x^2
x^-2
