Answer:
x = 3
Step-by-step explanation:
Given two secants drawn from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
x(x + 21) = (x + 1)(x + 1 + 14)
x² + 21x = (x + 1)(x + 15) ← expand using FOIL
x² + 21x = x² + 16x + 15 ( subtract x² + 16x from both sides )
5x = 15 ( divide both sides by 5 )
x = 3
Answer:
That would be cosine, or (cos)
Step-by-step explanation:
This is because cosine is Adjacent / Hypotenuse.
Hope that helps, :)
This is how I figure these type of questions out you can draw a circle on the J,K,L the trace it to make a triangle it should be less then 90 degrees if not then you might’ve traced it wrong.
we are given
standard form:
We will complete x , y and z square
make all x , y and z terms together
surface:
It is an infinite paraboloid
