Answer:
The last two functions are decreasing!
Step-by-step explanation:
You can easily tell the functions are decreasing if the function is going down from L to R. If it is going up, from L to R, then it is increasing!
Veronica traveled at 85 miles for 6 days and 52 miles on the final day making the total number of days traveled 7 days
<em><u>Solution:</u></em>
Veronica traveled 562 miles to Venice, Florida
She drove 85 miles every day
Let "d" be the number of days she drove 85 miles per day
On the last day of her trip she only drove 52 miles
Therefore, we frame a equation as,
Total miles = 85 miles every day for "d" days + last day
Total miles = 85(d) + 52
Total miles = 85d + 52
562 = 85d + 52
85d = 562 - 52
85d = 510
d = 6
She traveled at 85 miles for 6 days and 52 miles on the final day making the total number of days traveled 7
Answer: A
Step-by-step explanation:
A rhombus is a quadrilateral with all sides equal in length. A square is a quadrilateral with all sides equal in length and all interior angles right angles. Thus a rhombus is not a square unless the angles are all right angles. ... A square however is a rhombus since all four of its sides are of the same length.
A square is a quadrilateral with all four angles right angles and all four sides of the same length. So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles.

Answer:
- c(n) = 320·0.96^n
- 28 years
Step-by-step explanation:
Each year, the class size is multiplied by 1 - 4% = 96% = 0.96. After n years, it has been multiplied by that number n times. Repeated multiplication is signified using an exponent.
Class size (c) can be modeled by ...
c(n) = 320·0.96^n
__
You want to find n such that c(n) = 100. Put in that value and solve.
100 = 320·0.96^n
100/320 = 0.96^n . . . . . . . divide by 320
log(100/320) = n·log(0.96) . . . . . . . take logs
log(100/320)/log(0.96) = n ≈ 28.4932
In about 28 years, the class will have 100 students.
