Answer:
-13 degrees tell me if it's right
Two ways to answer:
A. Using calculus:
H(t)=-16t^2+65t+3
To find maximum of H(t), equate H'(t)=0, or
H'(t)=-32t+65=0 => t=65/32=2.03125, or
t=2.0 s. to the nearest 10
B, Without using calculus, i.e. by completing the square
H(t)
=-16t^2+65t+3
=-16(t^2-65/16t)+3
=-16(t^2-2*(65/32)t+(65/32)^2)+3+(65/32)^2
=-16(t-65/32)^2+3+(65/32)^2
meaning the maximum occurs at (t-65/32)=0, or t=65/32=2.03125
Answer: t=2.0 seconds (to the nearest tenth)
Answer:
Divide each term in
− 3 x = −12 by −3 and simplify. Then ur answer is x =4
Correct answer is C.
Both models have equal volume.
Model B has a larger surface area.
