Answer:
t1= 5.35
Step-by-step explanation:
Projectile height formula should be
h= -1/2gt^2+v0t+h0
where
h= height, this question asking time when "ball hit the ground" so height is 0
t= time, we look for this variable
v0= initial velocity= 85 feet/s
h0= initial height = 6 feet
g= gravity, assumed 32 feet/s^2
The calculation will be:
h= -1/2gt^2+v0t+h0
0= - 32 t^2+85t+6
0= -16t^2+85t+6
16t^2 - 85t -6 =0
x=
t=
t=
t=
t=
t1=
t1= 5.35
t2=
t2= -0.035
The answer can't be minus, so its t1
8.50x+60
that's what I have because you didn't say what the number of hours she worked.
In writing numerical numbers, you should identify the three-letter groupings. The first three-letter grouping would be the hundreds, followed by thousands, by millions, by billions, by trillions, and so on and so forth. In this case, we highest would be billions. So, in word form, that would be: three billion, one hundred fifty two million, three hundred eight thousand and seven hundred twenty six.
Answer:
54 centiliters
Step-by-step explanation:
Multiply the volume in liters by 100
When a perpendicular is dropped from the right-angle (C) to the opposite side AB, the metric relations apply:
BD*BA=a^2 ..........................(1)
AD*AB=b^2...........................(2)
BD*DA=DC^2........................(3)
Given AD=6, AB=24, using metric relation (2) above, we have
b^2=6*24=144
=>
b=sqrt(144)=12
By the way, we conclude that this is a 30-60-90 triangle because b/AB=(1/2)=sin(B) => B=30 degrees.
Answer: b=12
