Answer:
The length is 26 feet and the width is 23 feet
Step-by-step explanation:
Let l represent the length of the rectangle.
The width can be represented by l - 3, since it is 3 feet less than the length
Set up an equation:
l + l + (l - 3) + (l - 3) = 98
Add like terms and solve for l:
l + l + (l - 3) + (l - 3) = 98
4l - 6 = 98
4l = 104
l = 26
So, the length is 26 feet.
Since the width is l - 3, we can plug this in for l to find the width:
l - 3
26 - 3
= 23
So, the length is 26 feet and the width is 23 feet
The vertex of this parabola has coordinates (1,-1).
The axis symmetry goes trough the vertex. The equation of the axis of symmetry is x=1.
Answer:
- <u>The multiplicative rate of change of the function is 0.5</u>
Explanation:
The <em>multiplicative rate of change</em> is the ratio between consecutive entries.
Naming r the multiplicative rate of change, if it is constant you get:
- r = second entry / first entry = third entry / second entry = fourth entry / third entry.
Here:
- second entry / first entry = 0.125 / 0.25 = 0.5
- third entry / second entry = 0.0625 / 0.125 = 0.5
- fourth entry / third entry = 0.03125 / 0.0625 = 0.5
Thus, the multiplicative rate of change is 0.5. It means that you can obtain each entry as the product of the previous entry times 0.5:
- 0.25 × 0.5 = 0.125
- 0.125 × 0.5 = 0.0625
- 0.0625 × 0.5 = 0.03125
In general, exponential functions have constant multiplicative rate of changes.
The answer is C, 10 7/15 !
