Mike forgot to replace the cap on a bottle of room freshener. The room freshener began to evaporate at the rate of 15% per day.
riadik2000 [5.3K]
Percentages are out of 100. So we'll multiply by 0.85 to represent the 15%

To find the y points on the graph we can use f(x) = 0.85^x*40

We'll input 1-5 for x to find y:

1:  0.85^1=0.85*40=34
2: 0.85^2=0.7225*40=28.9
3: 0.85^3=0.614125*40=24.57
4: 0.85^4= 0.52200625*40=20.88
5: 0.85^5=0.443705312*40=17.75

Therefore the answer is a graph of exponential function going down from left to right in quadrant 1 through the point 0, 40 and approaching the x-axis.

vodomira [7]

Answer:

<em>Diameter= 11.27 feet</em>

Step-by-step explanation:

<em>Circle = 2πr</em>

<em>or, 11.27π = 2πr</em>

<em>or, 11.27π/2π = r</em>

<em>r = 5.635 ft</em>

<em>diameter = 2r</em>

<em>= 2 x 5.635</em>

<em>= 11.27 feet</em>

damaskus [11]

Step-by-step explanation:

(10, 9), (5 , 4)

Use the distance formula to determine the distance between the two points.

Distance

=√(x2−x1)² +(y2 - y1)²

Substitute the actual values of the points into the distance formula.

√(5−10)² +(4−9)²

Simplify.

5√2

Exact Form:

5√2

Decimal Form:
