Two rockets are launched from the ground at the same time. the height of rocket a in feet is modeled by

h(t)= -16t^2 + 128t

where t is the time in seconds after the launch. the height of rocket b in feet is shown in the graph.

which statement is true?

a. rocket a is in the air for about 2.75 s longer than rocket b

b. rocket a is in the air for about 10.75 s longer than rocket b

c. rocket b is in the air for about 2.75 s longer than rocket a

d. rocket b is in the air for about 10.75 s longer than rocket a

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

answer: f = 32.2m

step-by-step explanation: that is the answer

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
