You find this value by factoring. Factoring finds the zeros of the function. When the ball hits the ground, it has 0 height. Therefore, when the function goes through the x axis, it has a y value of 0. That means that when y = 0, the ball has hit the ground. Use the quadratic formula to factor 
. Notice I rearranged the terms. When you factor that you get zeros of -3.19 and 2.19. The two things in math that will never EVER be negative are time and distance/length. Therefore, that tells us that the ball hits the ground 2.19 seconds after it was thrown.
Answer:
There are 0.0328 centimeters in 1 foot.
Step-by-step explanation:
Given : There are 12 inches in 1 foot.
To find : How many centimeters are there in 1 foot?
Solution :
1 foot = 12 inches
and 1 inch = 2.54 centimeter
So, 12 inches = centimeter
12 inches = 30.48 centimeter
i.e. 1 foot = 30.48 centimeter
Then, 1 centimeter = foot
1 centimeter = 0.0328 foot
Therefore, there are 0.0328 centimeters in 1 foot.
Answer: x = 6
Step-by-step explanation:
Because we are given that the two figures are already similar, we can set up a proportional relationship to determine the value of x. Since the larger rectangle has a width of 21 and the smaller rectangle has a width of 7, those values can be used as the numerators in the proportion. Since the larger rectangle's length is x plus the additional 3 units on the smaller rectangle, x+3 and 3 can be used as the denominators in the proportion.
Next, we set up the proportion as follows:
Then, you cross multiply to get the equation:
After solving down algebraically, you get the value of x to be 6.
I hope this helps!
