Hello! I would love to help!
Okay! To find the average, you have to add up all the numbers, then divide them by however many numbers there are. They give us 4 numbers.
Let's start by adding them all!
26.1+24.3+32.8+18.2=101.4
Okay. Now, we have to divide that answer by 4 since there are 4 numbers we added.
101.4/4=25.35
So, the average time was 25.35 seconds!
Hope this helped! Comment if you have questions!
Answer:
the highest height would be 144
Answer:
(x+3)^2=-4(y-3)
Step-by-step explanation:
(x-h)^2 = 4p(y-k)
P is the distance between the focus and vertex
P = 1 --> used distance formula for the points of -3,2 -3,3
Vertex is -3,3 --> according to picture
(x+3)^2=-4(y-3)
P is negative since it goes downwards in the picture.
Our missing number we are solving for is X.
We are told x will equal 2x (number doubled) plus -16.
x = 2x + -16 We want to move the smaller variable to the right to sit with the larger one and move the -16 to the left by subtracting it from both sides. Remember that subtracting a negative is the same as adding it. So essentially we add 16 to both sides.
16 = 2x - x Combine the variables
16 = x or x = 16
I chose to put the variable on the left in this problem to avoid having a -x on the left side. It doesn't matter which side the variable is on to solve, but when you state it - we usually say x = 16.
