Answer:
<h3>This function states that the first hour has a fixed cost of 10.75.</h3><h3>Then, every additional hour has an additional cost of $8.14.</h3>
Step-by-step explanation:
The given function is
The statements that best represent the formula are:
- This function states that the first hour has a fixed cost of 10.75.
- Then, every additional hour has an additional cost of $8.14.
You can deduct that from the formula, because represents hour, so for , we have
Which means 1 hour costs $10.75.
Then, for
Which means an additional hour cost $8.14 additionally.
Answer:
a.x=39.2
b.Use whole wire as a circle
Step-by-step explanation:
We are given that
Length of piece of wire=70 units
Let length of wire used to make a square =x units
Length of wire used in circle=70- x
Side of square=
Circumference of circle=
Combined area of circle and square,A=
Using the formula
Area of circle=
Area of square=
a.
Differentiate w.r.t x
x=39.2
Again differentiate w.r.t x
>0
Hence, the combined area of circle and the square is minimum at x=39.2
b.When the wire is not cut and whole wire used as a circle . Then, combined area is maximum.
ANSWER
The pattern is geometric.
EXPLANATION
The given pattern is:
7, -21, 63, -189,..
We can see from the pattern that,
Since there is a common ratio of -3, the pattern is geometric.
The first term of this pattern is
The nth term of the pattern is given by the formula:
To find the 23rd term, we put, n=23, the first term and the constant ratio.
