The unit rate here is 2 pounds of trash in an hour. If two pounds of trash are picked up in an hour, we can multiply that by 3 and get that there will be 6 pounds picked up in 3 hours.
Answer:
5
Step-by-step explanation:
21-6=15/3=5
7.5 pounds of Swiss cheese, WOW
Answer:
Step-by-step explanation:
OK... You have to use this formula: <u>Y2 - Y1</u>
X2 - X1
- -2 represents X1
- 7 represents Y1
- 2 represents X2
- -5 represents Y2
<u>Y2 - Y1</u>
X2 - X1
<u>-5 - 7</u>
2 - - 2
<u>-12</u>
-2
Simplify by dividing both -12 & -2 by 2: <u>-6</u>
-1
It's either <u>-6</u> or it's just -6 by itself... Really sorry if I'm wrong...
-1
By using the arc length formula, we will see that the length of the curve is L = 1.48
<h3>
How to use the arc length formula?</h3>
Here we have the curve:
y = 2 - x^2 with 0 ≤ x ≤ 1
And we want to find the length of the curve.
The arc length formula for a curve y in the interval [x₁, x₂] is given by:

For our curve, we have:
dy/dx = -2x
And the interval is [0, 1]
Replacing that we get:

This integral is not trivial, using a table you can see that this is equal to:

evaluated from x = 1 to x = 0, when we do that, we will get:

That is the length of the curve.
