For the answer to the question above,
<span>Let's work with the left-hand side
We're going to times cosx/1-sinx by 1+sinx/1+sinx, you can do this because 1+sinx/1+sinx is equal to 1, so you aren't really changing anything.
After you've times the top and bottom by 1+sinx, you get:
cosx(1+sinx) / (1-sinx)(1+sinx)
The denominator is a difference of squares, so you get 1-sin^2 x
what you have now is
cosx(1+sinx) / 1-sin^2x
You know that 1-sin^2x is equal to cos^2x
so know you have
cosx(1+sinx) / cos^2x
get rid of the cosx on top by simplifying and the cos^2x so that you're left with
(1+sinx) / cos x
Therefore cosx / 1- sinx = 1 + sinx / cos x</span>
Answer:
4x + 276
Step-by-step explanation:
Multiply 4 by 69 and x.
<span>Let g(x) = f(x) - 4
g(x) is a translation of f(x) down 4 units so (-3, 1) will be the new point
find g(-3)
g(-3) = f(-3) - 4
= 5 - 4
= 1
hope this helps</span>
Answer:
87.5 %
Step-by-step explanation:
Set up a ratio:
7/8 = x/100
Cross multiply to solve for x:
8x = 700
x = 87.5
P(f | weekend) = p(f & weekend)/p(weekend)
.. = 10%/25%
.. = 2/5 = 0.4
