Answer:
Average rate of change = 1
Step-by-step explanation:
Average rate of change of a function between x = a and x = b is defined by,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
We have to find the average rate of change of the function in the interval 2 ≤ x ≤ 4
Therefore, average rate of change of the function = [tex]\frac{f(4) - f(2)}{4-2}[/tex]
From the graph attached,
f(4) = 4
f(2) = 2
Average rate of change = [tex]\frac{4-2}{4-2}[/tex]
= 1
Therefore, average rate of change of the function in the given interval is 1.
In ΔOPQ, o = 500 cm, p = 600 cm and q=380 cm. Find the measure of ∠P to the nearest 10th of a degree.
Answer: 84.8°
Step-by-step explanation:
a²+b²+c²-2bc(cosA)
cosA = b² + c² - a² / 2bc
That is the formula we will be using.
Then, plug in our numbers.
cosP= 500² + 380² - 600² / 2(500)(380)
cosP= 34400/380000
cosP≈ 0.09052631
cos⁻¹(0.09052631) ≈ 84.81
∠P = 84.8°

Difference between Simple Intrest and Compound Intrest
A line has a slope of 11 and passes through the point (2,4). PLSSSS HELPPP
Find the equation of the line.
Answer:
y=11x-18
Step-by-step explanation:
y=11x+b (b is the unknown y-int)
to find the y-int, substitute in (2, 4), and solve for b *substitute in 2 for x and 4 for y*
y=11x+b
4=11(2)+b
4=22+b
b=-18
the equation of the line:
y=11x-18

Answer:
area = 1539√3 in²
Step-by-step explanation:
three hexagons and one triangle:
each of the three hexagons are composed of 6 equilateral triangles just like the center triangle.
So you have 19 equilateral triangles with each side being 18 inches long.
The height (h) of a triangle will be:
h² = 18² - 9² = 324 - 81 = 243
h = √243
h = 9√3
area of one triangle = 1/2bh = (1/2)(18)(9√3) = 81√3
81√3(19 triangles) = 1539√3 in²

Is 7 a solution for the equation 3(x + 4)= 2x - (-2x)?
Step-by-step explanation:
3x+12=2x+2x
3x+12=4x
3x-4x=-12
-x=-12
x=12
Answer:
no, the answer is x = 12
Step-by-step explanation:
3(x + 4)= 2x - (-2x)
3(x + 4)= 2x + 2x
3x + 12 - 12 = 4x - 12
3x - 4x = 4x - 12 - 4x
-x = -12
x = 12
Amir pits £3035 into a bank account. The account pays 4% compound interest each year. Work out how much money amir will have in the account after 6 years
Answer:
[tex]\£3840.2[/tex]
Step-by-step explanation:
Let P denotes principal amount, T denotes time period and R denotes rate of interest.
Amount = [tex]P(1+\frac{R}{100})^T[/tex]
Amir pits £3035 into a bank account. The account pays 4% compound interest each year.
Put [tex]P=\£3035,\,R=4\%,\,T=6[/tex]
Amount = [tex]3035(1+\frac{4}{100})^6=3035(\frac{104}{100})^6=\£3840.2[/tex]
Therefore, Amir will have [tex]\£3840.2[/tex] in the account after 6 years.
7. A frying pan can hold 2 dozen wantons at a time.
It takes 5 minutes to fry 2 dozen wantons. How
long will it take to fry 40 dozens wantons
Answer:
100 minutes
Step-by-step explanation:
This is because it takes 5 minutes to fry 24 wantons, so we can write 5/24. Now we need to find out how long it takes to fry 40 dozen wantons, or 480 wantons. We can rewrite this as x/480. Since the time should be proportional, we get the following:
5/24 = x/480
We can now cross multiply. 24x=5x480. Therefore, 24x = 2400. If we divided each side by 24, we would get 100. Therefore, it takes 100 minutes to fry 40 dozen wantons, or about 1 2/3 hours.
Answer:
100 minutes (1 hour & 40 minutes).
Step-by-step explanation:
5 minutes = 2 dozen, which means it takes 2.5 minutes to cook 1 dozen.
2.5 minutes x 40 dozen = 100 minutes...

r = radius = 5in
area= 3.14 (5²)
= 3.14 x25
= 78.5 sq.in

Find the slope of the line that passes through the two points (7, -5) and (1, -13). (Don't forget to simplify!)
I don't want no links just the answer if u don't have the answer don't give me a link
Answer:
The slope would be 4/3 or 1 1/3.
Step-by-step explanation:
When you put the coordinates in the point-slope formula, you will get -5 - (-13) over 7 - 1. The answer becomes 8/6 but if simplified, it becomes 4/3 or 1 1/3 as a mixed fraction.
What is the end behavior of the function f(x)=2/3x^3? As x→[infinity], f(x)→−[infinity] As x→−[infinity], f(x)→−[infinity] As x→[infinity], f(x)→[infinity] As x→−[infinity], f(x)→[infinity] As x→[infinity], f(x)→[infinity] As x→−[infinity], f(x)→−[infinity] As x→[infinity], f(x)→−[infinity] As x→−[infinity], f(x)→[infinity]
Answer:
As x→[infinity], f(x)→[infinity] As x→−[infinity], f(x)→−[infinity]
Step-by-step explanation:
Since f(x) =2x³/3,
Let x → + ∞
Substituting x = + ∞ into the equation, we have
f(+∞) = 2(+∞)³/3
= + 2∞³/3
= + ∞ (since + 2∞³/3 → +∞ (a larger number))
So as x → + ∞, f(x) → + ∞
Let x → - ∞
Substituting x = - ∞ into the equation, we have
f(-∞) = 2(-∞)³/3
= - 2∞³/3
= - ∞ (since - 2∞³/3 → -∞ (a larger number))
So as x → -∞, f(x) → -∞
So, the answer is As x→[infinity], f(x)→[infinity] As x→−[infinity], f(x)→−[infinity]

The mean of Corey’s test scores is 90.2
What is Arithmetic Mean?The simplest method to determine the average for the given collection of integers is to use the arithmetic mean or mean. It is divided into two categories: weighted arithmetic mean and plain arithmetic mean.
The ratio of the total number of observations divided by the sum of all the given observations is known as the arithmetic mean.
We have,
Corey scored 85, 89, 87, 92, and 98 on his math tests.
So, arithmetic Mean
= (Sum of scores)/ Total number of score
= (85 + 89 + 87 + 92+ 98)/5
= 90.2
Thus, the Mean is 90.2

Kim has 12 ounces of water. She pours some waer into a bottle that holds exactly 1 cup. How many ounces of water are left over after him fills the bottle.
Answer:
4 ounces
Step-by-step explanation:
the measurement of water and the bottle are in different units. This, they have to be converted to the same units
1 cup = 8 ounces
if the bottle holds one cup, it would hold 8 ounces
ounces of water left over = 12 - 8 = 4 ounces
Explain the difference in meaning between 8+6 divided by 2 and 8 divided by 6 divided by 2
Answer:
In first case it is (8+6) whole divided by 2 that is 8/2+6/2 where u will get the answer 7.
in next case it is (8/6) then divided by 2
which will be 8/6*1/2.
(while converting from division to multiplication remember to take the reciprocal of the number after division sign in this 2 will become 1/2)
so and will be 8/12. 2/3 will be the answer....

Answer:
100 inches
Step-by-step explanation:
Given that the mans height is 71 inches. Height of lamp is 108 inches and distance between them is 52 inches. For Figure refer to attachment . The given figure both triangles are similar by AA similarity Condition. So we know that the corresponding parts of similar triangles are proportional .Let Distance between man a d its shadow be x .
Using this concept ,
=> AM / PN = QA / QP
=> 108 / 71 = 52 + x / x
=> 1.52 x = 52 + x
=> 1.52 x - x = 52
=> 0.52 x = 52
=> x = 52/0.52
=> x = 100 in .
