Answer:
t = 4.5 seconds
Step-by-step explanation:
It is given that, a golfer hits a ball from a starting elevation of 4 feet with a velocity of 70 feet per second down to a green with an elevation of −5 feet.
The number of seconds t it takes the ball to hit the green can be represented by the equation as follows :
......(1)
We need to find time taken by the ball to land on the green. Solving the quadratic equation (1) we get :
t = -0.125 s and t = 4.5 s
Ignoring t = -0.125 s, we get the time taken by the ball to land on the green is 4.5 seconds.
Answer:
The product in simplest form is ![-\frac{20}{27}](https://tex.z-dn.net/?f=-%5Cfrac%7B20%7D%7B27%7D)
Step-by-step explanation:
![(-\frac{8}{9}) (\frac{5}{6})\\\\=-\frac{20}{27}](https://tex.z-dn.net/?f=%28-%5Cfrac%7B8%7D%7B9%7D%29%20%28%5Cfrac%7B5%7D%7B6%7D%29%5C%5C%5C%5C%3D-%5Cfrac%7B20%7D%7B27%7D)
6x-2y=15
-6x -6x
-2y=-6x+15
2y=6x-15
Divide by 2 to both sides
y=3x-15/2
y=3x-7.5
Answer:
X=12
Step-by-step explanation:
Subttract 5 on both sides
x/3=4
Multiply by 3 on both sides to isolate the X
x=12
