Answer:
y = (2/9)(x + 1)² + 2
Step-by-step explanation:
y = a(x - (-1))² + 2
y = a(x + 1)² + 2
4 = a(2 + 1)² + 2
4 = 9a + 2
9a = 2
a = 2/9
y = (2/9)(x + 1)² + 2
Answer:
8 mph
Step-by-step explanation:
The equation for average speed is:
Let's start by finding the distance for each animal:
Now, we can find the average speed:
8 mph
Answer: the answer to this is 9 miles an hour
Step-by-step explanation: 1. What this is asking is to make the fraction a bit easier to understand. So all we do is divide the numerator by the denominator. You can use this method for any other math problems like this also.
2. All this chart is doing is multiply the input or output by 9. If you look you can see the hours is multiplied by nine. I hope this helped.
If you imagine a number line where 0 is in the middle, and all the negative numbers are on the left side of 0 and all the positive numbers are on the right side of 0, -28 will be 28 units across on the left side.
Therefore, to get back to 0, you need to go back 28 units (moving to the right), which is positive. Therefore, to make the sum 0, you need to add 28 to -28.
2(5+8)+101+101
Step 1: 2(13)+(101+101) =
Step 2:26+202=
Final Answer: 228
