Answer:
h(t) = = -16t^2 + 167t + 135
Step-by-step explanation:
This is an equation of motion of an object umder a constant acceleration(here it is the acceleration due to gravity);
h(t) = = -16t^2 + 167t + 135.
Note: t is the time in seconds and h is the height in feet at time t.
Answer:
24 possible outcomes
Step-by-step explanation:
Combination has to do with selection. For example, if r object is selected from a pool of n objects, the number if possible ways can be expressed according to the combination formula:
nCr = n!/(n-r)!r!
Applying this in question, if each student receives one of 4 calculator models and one of 3 types of ruler, the number of ways this can be done is:
4C1 × 3C1
4C1 = 4!/(4-1)!1! {If a student gets one calculator)
4C1 = 4×3×2/3×2
4C1 = 4ways
3C1 = 3!/(3-2)!1! {If a student gets a ruler}
3C1 = 3×2/1
3C1 = 6ways
Total number of possible outcomes if a student gets one ruler and one calculator will be 4×6 = 24ways
$30 = 75%, so divide it by three and you got your 25%, which ia $10.
$10 * 4 = $40.
So the answer is $40.

Answer:
23.31 ft
Step-by-step explanation:
Reference angle = 47°
Opp = 25 ft
Adj = x
Apply trigonometry ratio TOA:
Tan 47 = Opp/Adj
Tan 47 = 25/x
x*Tan 47 = 25
x = 25/Tan 47
x = 23.3128772 ≈ 23.31 ft (to 2 d.p)
Answer:
b
Step-by-step explanation:
$25 per day
it's "b" because as days increase the cost of dollars gets added by $25 per day.
Hope this helped!
