The question is incomplete, as the functions are not given.
The general explanation on calculating average rate of change is as follows.
The average rate of change (m) of function f(x) over interval (a,b) is:
[tex]m = \frac{f(b) - f(a)}{b-a}[/tex]
Take for instance:
[tex]f(x) = x^2 + 4x + 4[/tex]
[tex](a,b) = (0,2)[/tex]
The average rate of change over [tex](0,2)[/tex] is:
[tex]m = \frac{f(2) - f(0)}{2-0}[/tex]
[tex]m = \frac{f(2) - f(0)}{2}[/tex]
Calculate f(2) and f(0)
[tex]f(2) = 2^2 + 4*2 + 4 =16[/tex]
[tex]f(0) = 0^2 + 4*0 + 4 =4[/tex]
So, we have:
[tex]m = \frac{f(2) - f(0)}{2}[/tex]
[tex]m = \frac{16 - 4}{2}[/tex]
[tex]m = \frac{12}{2}[/tex]
[tex]m = 8[/tex]

Pam's eye-level height is 324 ft above sea level, and Adam's eye-level height is 400 ft above sea level. How much farther can Adam see to the horizon? Use the formula d = StartRoot StartFraction 3 h Over 2 EndFraction EndRoot, with d being the distance they can see in miles and h being their eye-level height in feet. 1 mi StartRoot 6 EndRoot mi 19 mi 19 StartRoot 6 EndRoot mi
Answer:
B. StartRoot 6 EndRoot mi
√6 mi
Step-by-step explanation:
A. 1 mi
B. StartRoot 6 EndRoot mi
C.19 mi
D. 19 StartRoot 6 EndRoot mi
d = √(3h/2)
Where,
d = distance they can see in miles h = their eye-level height in feet
Pam:
h = 324 ft
d = √(3h/2)
d = √{(3 * 324)/2}
= √972/2
= √486
= √(81 * 6)
= √81 * √6
= 9√6 mi
Adam:
h = 400 ft
d = √(3h/2)
d = √{(3 * 400)/2}
= √1200/2
= √600
= √(100 * 6)
= √100 * √6
= 10√6 mi
How much farther can Adam see to the horizon?
Adam - Pam
= 10√6 - 9√6
= √6 mi
the rectangle with 2 row nd each raw has 6 square each sudw of square is 1 cm determine the perimeter of rectangle and area of square
Answer:
Perimeter of rectangle is 16 cm and the area of square is 1 cm^2
Step-by-step explanation:
Here, we want to get the perimeter of rectangle and area of square
From the question, the rectangle has 2 rows of 6 squares each; So we have the length as 2 cm and the width as 6 * 1 cm = 6 cm
So the rectangle is 6 cm by 2 cm
The perimeter of a rectangle is 2(l + b)
so, we have 2(6 + 2) = 2(8) = 16 cm
The area of the square is simply the side length raised to the power of 2
we have this as 1^2 = 1 cm^2

Bob has 57 guests he wants to make sure everyone gets a slice of cake. One is 20cm at £13.50 and one 25cm at £18.75 he wants to pay as little as possible. How much will he have to pay
Answer:
£56.25
Step-by-step explanation:
Number of guest = 57
The 20cm cake :
Can serve 12 people and cost £13.50
The 25cm cake :
Can serve 20 people and cost £18.75
Since the cake has to be the same size, the only one particular size would have to be purchased ;
For the 20cm cake ; 57/12 = 4.75 = five 20cm cakes ;
£13.50 * 5 = £67.50
For 25cm cake ; 57 / 20 = 2.85 = three 25cm cakes
£18.75 * 3 = £56.25
£56.25 is lower ; hence, amount he'll have to pay is £56.25

Bob eats 1/4 of a pie and later eats 2/5 of the pie. What fractions remains?
Answer:
9/20
Step-by-step explanation:
After Bob eats 1/4 of the pie, he has 3/4 left. 2/5 of 3/4 is the same as (2/5)*(3/4) because "of" is used as multiplication in math. (2/5)*(3/4)=6/20, so he ate 6/20 of the pie. To get the answer, you need to solve 1-(1/4+6/20)=
1-(5/20+6/20)=20/20-11/20=9/20. I hope this helps and sorry if I made a mistake. :)

Witch statement about a quadrilateral is true 1. A rhombus has exactly one pair of parallel sides. 2. A trapezoid has two pairs of parallel sides. 3. All rectangle are squares. 4. Some rhombus have four right angles
Answer:
Statement 4 is true.
Step-by-step explanation:
- Statement 1 is false because a rhombus has 4 equal sides with 2 pairs being parallel to each other.
- Statement 2 is false because a trapezoid usually has only 2 sides that are parallel while the other 2 are not parallel. Thus it has only a pair of parallel sides.
- A square must have all 4 sides equal. But rectangles don't have all 4 sides equal and so the statement is false.
- Rhombus has all 4 sides equal and where it has all interior angles as right angles, it is called a square. Thus, some rhombus have all 4 interior angles as right angles.

James can write 6 paragraphs in 24 minutes.
Using the same unit rate, how many paragraphs can James write in 16 minutes?
Lets find out how many a minute. 3 in 12 minutes, 1 in 4 minutes, so 1/4th of a paragraph per minute.
Now 1/4 times 16 = 4. So he can write 4!

A cone has a radius of 12 inches and a slant height of 20 inches. What is the approximate surface area of the cone?
Answer:
2009.6 in²
Step-by-step explanation:
The surface area, SA of a cone is obtained using the formular :
SA = πr² + πrl
Where ; r = Radius = 20 inches ; l = slant height = 12 inches
SA = π*20² + π*20*12
SA = 400π + 240π
Take π = 3.14
SA = (400*3.14) + (240*3.14)
SA = 1256 + 753.6
SA = 2009.6 in²

Tawana has $325.54 in her checking account. She must keep a balance of at least $300 to avoid a fee. She plans to write a check to pay her to pay her credit card bill of $125.43. how much must Tawana deposit in her checking account to maintain atleast the minimum balance?
hi
Answer: To pay her bill with the minimum balance to avoid the fee, she needs the total amountof $300+$125.43=$425.43. But she only has $325.54. So, the extra minimum amount she needs to deposit is 425.43-325.54=$99.89.
Hence, the answer is $99.89.

Solve for the variable: p - 4.2 = 2. Show your work
Answer:
6.2
Step-by-step explanation:
P - 4.2 =2
we have to no separate the variables and constants
so , when we move 4.2 to the other side ( other side of 2) it will be something like this
p = 2+4.2
as you can wee when we moved 4.2 to the other side the operation changed from ,minuus to plus sign .
now just do what it says
formula :
=p-4.2=2
=p = 2+4.2
= 2+ 4.2= 6.2
so,
p=6.2
write the formula , I think no need to write explanation
Sam is 34 years younger than Ashton. 4 years ago, Ashton's age was 3 times Sam's age. How old is Sam now?
Answer:
21years old
Step-by-step explanation:
Let Sam's age be x
Let Ashton present age be y
If Sam is 34 years younger than Ashton then;
x = y - 34 .... 1
If by 4 years ago, Ashton's age was 3 times Sam's age then;
Sam = x - 4
Ashton = y - 4
y-4 = 3(x-4)
y-4 = 3x - 12 ....2
Substitute 1 into 2;
y-4 = 3(y-34)-12
y-4 = 3y-102-12
y-4 = 3y - 114
y-3y = -114 + 4
-2y = -110
y = 110/2
y = 55
Since x = y- 34
x = 55-34
x = 21
Hence Sam will be 21years old now

A triangular parcel of land has side lengths of 100, 580, and 600 feet. Approximate the area of the land. Round your answer to the nearest foot.
Answer:
28800 square feet
Step-by-step explanation:
We solve this using the Heron's formula
Area of a Triangle = √s(s - a)(s - b)(s - c)
s = a + b + c/2
s = 100 + 580 + 600/2 = 640
Area of the land(Triangle) = √640 × (640 - 100)(640 - 580)(640 - 600)
= √640 × (540) ×( 60) × (40)
= √(829440000)
= 28800 square feet
Therefore, the approximate the area of the land is 28800 square feet.
