Write the equation of the parabola in standard form and find the vertex of its graph.

y=x^2+10x+16

a: y=(x+5)^2-9; vertex: (5,-41)
b: y=(x-5)^2+11; vertex: (5,41)
c: y=(x+8)(x+2); vertex: (10,16)
d: y=(x+5)^2-9; vertex: (-5,-9)
e: y=(x+5)^2+41; vertex: (-5, 41)

Aresearch company wants to test the claim that a new multivitamin to improve short term memory. state the objective of the experiment, suggest a population, determine the experimental and control groups, and describe a sample procedure.

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
