Answer:
It's ratios. Comparisions I think
Step-by-step explanation:
The speed of the runner:Number of races she won- Positive
The size of the vehichle:Miles per Gallon of gas in the tank so how far it can travel- Negative
The number of the Telephones you own:Calls you recieve-Positive
Do you have another thing to show? Or is it just that?
The answer is 8.
first of all you need to find the missing length on the adult version.
so the work would be:
-add up all the known sides of adult so
(56+56+35)=147
-then take the total perimeter and subtract so
167-147=20
-then you need to compare the two known sides of both the adult and kids version. so that would be the bottom line EM.
They are 35 and 14 so divide
35/14=2.5
Now you know the dilation so you can figure out the missing side GA on the childs by taking the missing side from the adult dividing by the dilation 2.5 to get the answer so
20/2.5= 8
the answer is 8.
I got this correct on the quiz.
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
