Sine - opposite : hypotenuse
Cosine - adjacent : hypotenuse
Tangent - opposite : adjacent
Cosecant - hypotenuse : opposite
Secant - hypotenuse : adjacent
Cotangent - adjacent : opposite
Answer:
You would have to find the area of the whole rectangle without the spece, so it would be 30mm x 15mm, the result would be 450 square mm.
Then you find the area of the empty space which would be 10mm x 8mm, the result: 80 square mm.
You substract the area of the space from the whole rectangle, which would be 370 square mm, this is the area of the figure
Answer:
A
Step-by-step explanation:
F(x) = 4x - 9
let f(x) = y, this implies that x = f⁻¹(y)
y = 4x - 9 Let us solve for x.
4x - 9 = y
4x = y + 9
x = (y + 9)/4
Recall that x = f⁻¹(y),
x = (y + 9)/4
f⁻¹(y) = (y + 9)/4
That means that for f⁻¹(x)
f⁻¹(x) = (x + 9)/4
Hope this explains it.
