A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator descends 6 feet per second. The elevator for the miners descends 16 feet per second. One day, the equipment elevator begins to descend. After 28 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 14 seconds? At that time, which elevator is deeper?
Answers
Answer:
equipment: -252 feet; miners: -224 feetequipment is deeperStep-by-step explanation:
The attached graph shows the depth of the elevators with respect to the time the miners' elevator started.
After 14 more seconds, the positions are ...
equipment: -6(42) = -252 feet relative to the surface
miners: -16(14) = -224 feet relative to the surface
The equipment elevator is deeper.

1. y=-(x-6)^2+7 vertical compression or stretch
2. y=1/4(x+5)^2 vertical compression or stretch
3. y=4(x+1)^2-6 vertical compression or stretch
Answers
Answer:
1. No vertical compression or stretching but will open up downward.
2. 1/4 vertical stretch
3. 4 vertical compression
Step-by-step explanation:
Any time your dealing with vertical stretching or compression it will always be the number before the parentheses.
So in 1. it is - or basically -1 which means the parabola will be open up downward. And in this problem there is no stretching or compression
2. Is the 1/4 is a vertical stretch
3. 4 is a vertical compression.
Or what also could help is when the number before the parentheses is bigger such as number 4 the closer together the parabola will be. And the smaller the number like 1/4 the wider the parabola will be.

find BKA and ABK

232/2 = 116
BKA =116
ABK = 116
find AKS
180 - 116 = 64
AKS =64
Now you have KAS and AKS
add together and subtract sum from 360 to find BSK
52 + 64 = 116
360 - 116 =244

A rope which is 10.3 centimeters long is cut into 4 pieces of equal length. Write an equation to find the length of
each piece? Use x as the length of each piece of rope.
Answers
x - 4 = 10.3 EQUATION
SOLUTION:
x = 10.3 + 4
x = 14.3
Answer: x = 10.3 ÷ 4
Step-by-step explanation: if we were to work this out forgetting about the equation it can be worked out by dividing the 10.3 by 4 to find the length of the pieces so, now to express it as an equation, we have to add x into our sum 4 × ? = 10.3 : 4x = 10.3. The answer for x would be x = 2.58.

Answers
Answer:
They are 260 miles apart. No it would not be possible.
Step-by-step explanation:
If they are 260 miles apart and you drive at a constant speed on 70mph. You will have to 260/70 which = 3.7 or 4 so it would not be possible.
Amarillo and Oklahoma City are [tex]260[/tex] miles apart.
It is not possible to make this trip in [tex]3[/tex] hours.
By using any geographical tool, such as the local map or you can use internet too to find the distance between Amarillo and Oklahoma City.
Amarillo and Oklahoma City are [tex]260[/tex] miles apart.
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Time = \frac{Distance}{Speed}[/tex]
[tex]Time = \frac{260}{70}[/tex]
Time [tex]= 3.714[/tex] hours
So, it is not possible to make this trip in [tex]3[/tex] hours.
