Answer:
See below.
Step-by-step explanation:
The rocket's flight is controlled by its initial velocity and the acceleration due to gravity.
The equation of motion is h(t) = ut + 1.2 g t^2 where u = initial velocity, g = acceleration due to gravity ( = - 32 ft s^-2) and t = the time.
(a) h(t) = 64t - 1/2*32 t^2
h(t) = 64t - 16t^2.
(b) The graph will be a parabola which opens downwards with a maximum at the point (2, 64) and x-intercepts at (0, 0) and (4, 0).
The y-axis is the height of the rocket and the x-axis gives the time.
Maximum height = 64 feet, Time to maximum height = 2 seconds, and time in the air = 4 seconds.
Answer:
6 + 8x
46
Step-by-step explanation:
1. Write the expression
6 + 8x
2. Plug in 5 for x
6 + 8(5) → 6 + 40 = 46
<u><em>You want to leave a 18% tip on a meal that cost $150.</em></u>
<u><em>First, convert the 18% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.</em></u>
<u><em>Second, you need to find out what 18% of your $150 meal cost is.This is always done by multiplying 0.18 by $150.00, or</em></u>
<u><em></em></u>
<u><em>0.18 x $150.00=$27.00.</em></u>
<u><em>So, the amount of tip you are going to leave is $27.00.</em></u>
<u><em></em></u>
<u><em>This makes the total cost of your meal (to write on your charge slip or other payment)</em></u>
<u><em></em></u>
<u><em>$150.00 + $27.00 = $177.00. </em></u>

Answer:
5/ 19 ≈ 0.26 = 26%
Step-by-step explanation:
given: student is female. there is a 100% chance that the student is female
probability we want = (favorable outcomes) / (total outcomes)
total outcomes = 19 because there are 19 female students and the student must be female
favorable outcomes = 19 - 14 = 5 females who do not have an A in the class
probability = 5/ 19 ≈ 0.26 = 26%
Answer:
B.
Step-by-step explanation:
-5/-7×-11/-6
= (-5 * -11) / (-7*-6)
= 55 / 42.
A. = - (6/-11) = 6/11
-5/7 * 6/11 = -30/77.
B. - (-11/7) = 11/7
5/6 * 11/7
= 55/42.
