Okay. On neopets, I need to know this answer to get an Avatar, and some money!
Thanks.
Here is the question:
A Pteri with a light appetite could not finish his Rainbow Melt Pizza. In fact, he could only eat exactly half of it.

If the diameter of the pizza was 50cm, and the half-pizza was a perfect semicircle, what is the area of the smallest square box, in square centimetres, that could contain the half pizza? Please disregard the thickness of the box, round to the nearest whole number, and please only submit a number for your answer.

Hi,

I need to calculate the integral of:

-2sin(t) * e^(2cos(t)) + cos(t) * e^(sin(t)) dt.

Is it just: 2cos(t) * e^(2cos(t)) + sin(t) * e^(sin(t))?


Thanks!

The skateboarder in the drawing starts down the left side of the ramp with an initial speed of 7.96 m/s. If non-conservative forces, such as kinetic friction and air resistance, are negligible, what would be the height h of the highest point reached by the skateboarder on the right side of the ramp?

(a) may be recessive or dominant.
(b) Is always recessive
(c) is always dominant
(d) is always found in the parents, if it's present in the progeny
(e) is never found in the parents, if it's present in the progeny

(a) two functional alleles are needed to make melanin.
(b) two dominant alleles are needed to make melanin.
(c) only one functional allele is needed to make melanin
(d) two recessive alleles are needed to make melanin.
(e) one recessive and one dominant allele are needed to make melanin

3. A father is heterozygous for the Rh-antigen gene. The mother is homozygous recessive. These parents are concerned that an embryo with Rh+ blood will be attacked by the immune system of the mother. What is the probability that an embryo they conceive will be Rh+?
0.10, 0.20, 0.25, 0.50, or 0.75..
