Plastic behavior: This permanent deformation behavior occurs when the tensile (or compressive) uniaxial stress reaches sy. Hard materials like diamond, nitrided steel and even most plastic are resistant to permanent deformation.

5 is really a repeat of 3, and the answer there is c.
in 4, if dimples is dominant and the parent is homozygous, the parent has two dimple genes, so every offspring MUST get a dominant dimple gene from that parent.
for problem 3, crossing !@#$%^& with !@#$%^& will give Ss - short hair Ss - short hair ss - long hair and ss - long hair. Half have long hair and half have short, so the answer is B.
I wouldn't trust Anonymous's answers. Homozygous means that animal has two of the same allele. To guarantee an offspring will have a recessive trait (in problem 2) both parents must be homozygous in the recessive allele (if not, the child could get the
to tell if a number is divisible by 3, add up the digits. IF the sum is divisible by 3, so is the original number. here 3+7+1=11, so 1, 4, and 7 as the last number would give you 12, 15, and 18 as the sum of the digits, so 1, 4, and 7 are the three

You left out information in your equation. The equation I find for this is D=sqrt(13h). The equation in your book may be differnt. Solve for h D^2=13h h=(D^2)/13
The order is not important. The answer is x=-2 or x=1 Verify by substituting for x 2(-2)^2+2(-2)-4=0 8-4-4=0 0=0 2(1)^2+2(1)-4=0 2+2-4=0 0=0
30,000*50*.05=75,000

slope intercept is y=mx+b. Find the slope (m) using the points. (delta y / delta x). Then substitute a point to find b.
You're on the right track. sin 2x= 2sin x cos x (identity) substitute into your first answer. f'(x)=2x-2(sin2x) f'(x)=2(x-sin2x)

range of tolerance because the organism has to react to it's environment. It can't control it.
Draw a picture of the problem. You should get to the forumlae 700=24L+84W with basic math. Solve for L (or W). A=LxW. Maximum Area occurs when derivative = 0. Take derivative and solve for L (or W).
Length is 6 less than 3xwidth so L=3W-6 Perimeter = L+L+W_W or 2L+2W Perimeter is 100m so 2L+2W=100 You have 2 equations and 2 unknowns so you can solve it.
In algebra terms, you could look at the problem like this: A. Set your variables. Do this by thinking about which parts of the problem can change. For this problem, there is the height of the final bounce, the height of the building, and the number of
