Answer:
10.625 seconds
Step-by-step explanation:
distance = speed · time
We want the total of all distances to be zero.
(-3.5)(90) +(2.2)(120) +(4.8)t = 0
-315 +264 +4.8t = 0 . . . . . simplify
-51 +4.8t = 0 . . . . . . . . . . . simplify more
-10.625 +t = 0 . . . . . . . . . .divide by 4.8
t = 10.625 . . . . . . . . . . . . . add 10.625
It will take the scientist 10.625 seconds to reach sea level.

Step-by-step explanation: you don’t need to cheat young one
The functions will be defined as y = x² if 0 ≤ x < 3, y = -x + 10 if 3 < x ≤ 6, and y = x + 2 if 6 ≤ x ≤ 10.
<h3>What is a function?</h3>
A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The graph is given below.
The function can be defined as
The parabolic equation will be
f(x) = x²
The equation of the absolute function will be
f(x) = |x - 6| + 4
Then we have

Answer:
3 3/8
Step-by-step explanation:
1 3/4 + 1 5/8
We need to get a common denominator of 8
1 3/4 *2/2 + 1 5/8
1 6/8 + 1 5/8
I like to line them up vertically
1 6/8
1 5/8
---------------
2 11/8
But 11 is larger than 8 so we subtract 8/8 and add 1
2 11/8
+1 -8/8
