Answer: Option C. Ellipse
Step-by-step explanation:
The general equation of an ellipse has the following form:

Where the point (h, k) is the center of the ellipse
In this case we have the equation

Note that its shape matches that of a ellipse with center (9, -2)

Therefore the answer is the obtion C
Answer:
67.1
Step-by-step explanation:
You would see if the 3 can go into the seven and seven into three to make it 4, 4 into eight 8 into 6 to make it 7 and then when you get to eight you would round it up into nine to make it 10.
13. Pick a point and see which formula works.
Ay = -4, A'y = 7. Only the formula of selection D makes that translation.
14. Use the compound interest formula A = P*(1 +r/n)^(nt).
..1500*1.015^80 = 4935.99, matching selection C
15. The lid has a perimeter of 90", so the area of the sides is
.. 90" * 24" = 2160 in^2
The area of the lid is
.. 30" * 15" = 450 in^2
The gray area is (2160 -450) in^2 = 1710 in^2 larger, corresponding to selection C.
16. The only formula that maps (7, -1) to (21, -3) is that of selection D.
_____
The middle two problems are the only ones that require you to have prior knowledge. The others could be answered simply by seeing if the answers work.
Answer: 3.62 inches
Step-by-step explanation:
Diego's cousin is too short for this ride, we know how tall he is now and what height he needs to be.
This can be solved by subtracting his needed height from his current height.
39.37-35.75=3.62 inches
