Answer:
t = 25.1seconds
Step-by-step explanation:
X(t)= 16cos75°t
Y(t)= 6 + (Vosin75°t - 16t^2)
Converting 78 yards to feet :
1 yard = 3 feet
78feet =?
78×3=234 feet
Y(t)= number of feet above the ground at t seconds
VoCos75° t = 234
t = 234/(VoCos75°)
At this time,4 = y(234/VoCos75°)
4 = 6 + VoSin75°(234/VoCos75) - 16(234/VoCos75°)^2
Vo= 140.66ft/s
Time,t= 234/(140.66× Cos75°)
t = 25.087seconds
t= 25.1 seconds (1 decimal place)
The area of the rectangle would be 13.5 inches.
Answer:
Home equity can be a long-term strategy for building wealth.
Answer:
$18.15
Step-by-step explanation:
Given that price before tax = $220
State sales tax rate = 4.6%
Dollar amount of state sales tax,
= 4.6% x $220
= 0.046 x 220
= $10.12
County sales tax rate = 3.65%
Dollar amount of state sales tax,
= 3.65% x $220
= 0.0365 x 220
= $8.03
Total amount of sales tax = $10.12 + $8.03 = $18.15
Answer:
The temp started at 12.
Step-by-step explanation:
The temp dropped 21 degrees to -9.
Let t be the old temp.
-9 = t - 21
t = 12
