Answer:
Result at time x = 4 seconds the soccer ball hit the ground.
Step-by-step explanation:
At the moment just before the ball is kicked, it is on the ground and so the height f(x) is zero meters. After the kick, the ball goes through the air and it's path can be described by a (mountain) parabola.
So lets see after how many second (x) the height = 0 once again.
f(x) = 8x-2x^2
f(x) = 0
8x - 2x^2 = 0
Try to write the formula in two terms
-2x * (x - 4) = 0
When a product of two or more terms equals zero, then at least one of the terms must be zero.
Now solve each term = 0 separately, meaning, solve as many equations as there are terms in the product.
Any solution of term = 0 solves product = 0.
Solve the first term:
-2x = 0
Multiply left an right from the = singn with the factor -1 gives this outcome:
2x = 0
x = 0
Solve the second term:
x-4 = 0
x = 4
Result at time x = 4 seconds the soccer ball hit the ground.
x = 4
x = 0
Answer:
39 and 27
Step-by-step explanation:
GIVEN: Robbie, has scored 
so far this season. He has scored all of his points on 
-point extra point kicks and 
-point field goals. He has made a total of 
kicks.
TO FIND: How many of each kick has he made.
SOLUTION:
Lets extra point kicks made by Robbie be 
points scored using extra point kick 
field goal kicks made by Robbie 
point scored using field goal kick 
Total points scored by Robbie 
Total points scored are the sum of points scored by extra point kicks and field goal kicks.
total extra point kicks 
total field goal kicks 
Hence Robbie made 39 and 27 kicks of extra point kick and field goal kicks respectively.
Answer:40,503
14,256 was the money that got taken away and 26,247 is how much she had left so in total if you add you’ll get 40,503.
