Answer:
The rider is 15.91 seconds 50 ft above the ground after reaching the low point
Step-by-step explanation:
We can evaluate the angle α
using trigonometry applied to the orange small triangle with height 50-30 = 20 ft and hypotenuse equal to the radius r = 25ft
Now
So 50
ft of height corresponds to the total angle:
= 2.498 radians
Now the angular velocity
To describe 2.498 rad it will take:
t = 15.91
s
Answer:
11j - 1573/10
Step-by-step explanation:
J = 10v /11 +143
collect terms
J - 143 =10v /11
11 (J -143) = 10v
Divide both sides by 10
11(J - 143)/10 = v
v = 11J - 1573/10
Hope this helps!
Answer:
23) 8
24)58
25)im guessing theyre both 90
Step-by-step explanation:
23)if ac=23 then 15-23=x
24) since it's a 90 degree angle the 32+x=90
and 90-32=58
<span>Each team in the softball league plays each of the other teams exactly once. For every game, there is 2 team playing. The order is not important because A vs B is same as B vs A
So you just need to makes a combination of 2 that have a result of 21. If there is t number of teams, the number of matches would be:
tC2 = t!/2!(t-2)! = 21
</span>t! / (t-2)! = 21 *2
(t)(t-1)= 42
t^2 -t -42=0
(t-7)(t+6)
t=7 ; t=-6
Excluding the minus result, you got 7 teams.
28.1 - 2.02 = 26.08
The second tank holds 26.08 more gallons of water than the first one.
