So 45% OF 40 is
45% * 40
0.45 * 40
that is 18
18 is 18% of what number?
18 = 18% * x
18 = 0.18 * x
divide both sides by 0.18
100 = x
45 % of 40, which is 18, and is 18% of 100.
Hope this helps
Answer:
21.25
Step-by-step explanation:
We can use the Pythagorean theorem to solve
We have the two legs and are looking for the hypotenuse
a^2 + b^2 = c^2
17^2 +12.75 ^2 = c^2 where c is the diagonal
289 +162.5625 = c^2
451.5625 = c^2
Take the square root
sqrt(451.5625) = sqrt(c^2)
21.25 =c
Answer:
, x>=0
Step-by-step explanation:
To find the inverse function , replace f(x) by y
Replace x with y and y with x
Solve the equation for y
take square root on both sides
Now subtract 6 from both sides
replace y with g(x)
Base times with times height but with a circle there is a formula made specifically for it
Answer:
sinθ = -0.554
tanθ = -0.667
secθ = 1.203
Step-by-step explanation:
Consider the point (3, -2)
The value of x is positive and the value of y is negative.
It means the the terminal sides of angle lies in 4rth quadrant, such that:
Base = 3
Perpendicular = 2
Hypotenuse² = 2² + 3²
Hypotenuse = 3.61
sinθ = Perpendicular /Hypotenuse
sinθ = 2/3.61
As sine is negative in 4rth quadrant
sinθ = - (2/3.61)
sinθ = -0.554
tanθ = Perpendicular/ Base
tanθ = 2/3
tanθ = 0.667
As tan is negative in 4rth quadrant
tanθ = -0.667
secθ = Hypotenuse/Base
secθ = 3.61/3
secθ = 1.203
secant is positive in 4rth quadrant
