I believe your answer is 6 seconds.
Because the height of the ball = -16(x² - 5x - 6), when the height of the ball is 0, which is when it is on the ground, we can set -16(x² - 5x - 6) equal to 0. This also allows us to divide by -16, and then we can solve the equation:
x² - 5x - 6 = 0
(x - 6)(x + 1) = 0
So x = 6 or x = -1, and because a quantity of time cannot be negative, x would have to be 6, which means it takes 6 seconds for the ball to reach 0 feet.
I hope this helps!
Answer:
x = -4
Step-by-step explanation:
-2x-11=-3x-15
x - 11 = -15
x = -4
Answer:
Mean: 49
Median: 41
Mode: 45
Range: 70
Step-by-step explanation:
To find the mean: add up all the numbers, then divide by how many numbers there are.
To find the median:
Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
To find the mode: The mode of a data set is the number that occurs most frequently in the set.
To find the range: The range is the difference between the smallest and highest numbers in a list or set. To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest.
Answer:
From left to right, -3/2, -4/5, -3/10, 1/2, 7/8, 4/3
Step-by-step explanation
So what we're trying to do here is to order the numbers from greatest to least.
Let's start off with the negative numbers.
-3/10, -4/5, -3/2.
Now what we want to do is give them all a common denominator to figure out which one is the least of that group.
-3/10,-8/10,-15/10.
Now on to the positive numbers.
1/2, 4/3, 7/8
Turn the denominator into 24.
12/24, 32/24, 21/24
Then put them all in order.
