Answer:
2500 x 1.06 + 2500 x 1.03
Step-by-step explanation:
2500 x 1.06 = 150
150 x .5 (half the simple interest) = 75
150 + 75 = 225
First off, let's notice that the angle is in the IV Quadrant, where sine is negative and the cosine is positive, likewise the opposite and adjacent angles respectively.
Also let's bear in mind that the hypotenuse is never negative, since it's simply just a radius unit.

Answer:
the answer to your question is C
Answer:
4z^2+7z
you have to combine the like terms
7z+4z^2+6-6
then becomes
(4z^2) + (7z) + (6-6)
gets you to the simplified version which is
4z^2 +7z
Similar triangle Hypotenuse must have similar slopes. If you'll notice, y & x are parallel lines, so they will have equivalent slope
In short, Your Answer would be 4/5
Hope this helps!
