Answer: 5/6, 0.83333333
Step-by-step explanation:
This tells you two things
1-r is positive, so grade school performance and Regents exam score tendto increase and decrease together.
2-r is fairly close to 1, so the direct relationship is fairly strong.
The future value of her investment will be
.. 3000*(1.1^35 -1)/(1.1 -1) ≈ 813,073.11
That supports 30 years of annual payments of
.. 813,073.11*(.1)/(1 -1.1^-30) = 86,250.18
_____
The compound interest and annuity formulas in your text are applicable.
Answer:
For the first equation the answer for "X" will be,
if you want me to solve for y instead then the answer will be,
for the second equation the answer for "X" will be,
If you want me to solve for y instead then the answer will be,
Answer:f(x) = a(x – h)² + k
we know the vertex v(5,3)
substitute in the values for h and k
f(x) = a(x – 5)² + 3
Use another point and substitute in values for x and f(x).
for the point (6,5)
Solve for a.
5 = a(6 – 5)2 + 3-------------- > 5=a+3-------------> a=2
The function is f(x)=a(x – h)2 + k-------- > 2(x – 5)² + 3
f(x)= 2(x – 5)² + 3-------- > 2[x²-10x+25]+3=2x²-20x+50+3=2x²-20x+53
f(x)=2x²-20x+53
the answer is f(x)= 2(x – 5)² + 3----------------- > (f(x)=2x²-20x+53)
