Answer:
The answer is below
Step-by-step explanation:
Given that f(x)=x(22-x)
a) f(x)=x(22-x)
f(x + h) = (x + h)(22 - (x + h))
f(x + h) = (x + h)(22 - x - h)
f(x + h) = (22x - x² - xh + 22h - xh - h²)
f(x + h) = (-x² + 22x - h²+ 22h - 2xh)
b) f(x)=x(22-x) = 22x - x²
f(x + h) = (-x² + 22x - h²+ 22h - 2xh)
f(x+h)- f(x) = (-x² + 22x - h²+ 22h - 2xh) - (22x - x²)
f(x+h)- f(x) = -x² + 22x - h²+ 22h - 2xh - 22x + x²
f(x+h)- f(x) = -x² + x² + 22x - 22x - h²+ 22h - 2xh
f(x+h)- f(x) = - h²+ 22h - 2xh
c) f(x+h)- f(x) = - h²+ 22h - 2xh
[tex]\frac{f(x+h)-f(x)}{h}=\frac{- h^2+ 22h - 2xh}{h}\\ \\\frac{f(x+h)-f(x)}{h}=\frac{- h^2}{h}+\frac{22h}{h}-\frac{2xh}{h}\\\\\frac{f(x+h)-f(x)}{h}=-h+22-2x[/tex]
[tex]\lim_{h \to 0} \frac{f(x+h)-f(x)}{h}= \lim_{h \to 0} (-h+22-2x )=22-2x[/tex]

Each side of a square field is 50m long. A barricade is to be placed along the diagonal of the field. Find the length of the barricade.
Answer:
70.71m
Step-by-step explanation:
In order to find the diagonal, we can use Pythagiras theorem by splitting the field in half and creating a right angled triangle.
A^2+B^2=C^2
50^2+50^2=C^2
5000=C^2
Square root 5000= 70.71m (2dp)
Hope this helped!
Since there is a barricade placed along the diagonal sq field, let's focus on one side of the triangle.
A pythagoras theorem formula can be used for right angle triangle.
So now we let the barricade be X.
By Pythagoras Theorem,
X² = 50² + 50²
X = sq root (50² +50²)
= 70.711 m ( 5sf)
= 70.7 m ( 3sf)
Therefore, the length of barricade is 70.7 m

Step-by-step explanation:
A florist has 60 tulips and 72 daffodils. The florist will make bouquets with the same number of tulips and the same number of daffodils in each using all the flowers. What is the greatest number of bouquets the florist can make?
Answer:
12
Step-by-step explanation:
No of tulips = 60
No of daffodils = 72
We need to find the greatest number of bouquets the florist can make if the florist will make bouquets with the same number of tulips and the same number of daffodils in each using all the flowers.
It would mean that we need to find the HCF of 60 and 72
Prime factorisation of 60 = 2×2×3×5
Prime factorization of 72 = 2 x 2 x 2 x 3 x 3
Highest common factor or HCF = 2×2×3 = 12
So, the florist can make 12 bouquets as maximum number.

Write the equation for the line that passes through (-5, -4) and (3, 12)
Answer:
I believe it is y=2x+6.
Answer:
[tex]y=2\,x+6[/tex]
Step-by-step explanation:
Start by finding the slope of the segment that joins the two given points, using the slope formula:
[tex]slope=\frac{y_2-y_1}{x_2-x_1} =\frac{12-(-4)}{3-(-5)} =\frac{16}{8} =2[/tex]
Now, you can write the general equation of the line in slope-intercept form as:
[tex]y=m\,x+b\\y=2\,x+b[/tex]
and find the line's y-intercept (b) by using either one of the given points - for example (3, 12):
[tex]y=2\,x+b\\12=2\,(3)+b\\12=6+b\\b=6[/tex]
Therefore, the equation of the line is:
[tex]y=2\,x+6[/tex]

The percentage of U.S. college freshmen claiming no religious affiliation has risen in recent decades. The bar graph shows the
percentage of first-year college students claiming no religious affiliation for four selected years from 1980 through 2012
a. Estimate the average yearly increase in the percentage of first-year college females claiming no religious affiliation. Round the
percentage to the nearest tenth.
b. Estimate the percentage of first-year college females who will claim no religious affiliation in 2030,
Answer:
0.5%/year
24.2%
Step-by-step explanation:
Estimate the average yearly increase in the percentage of first-year college females claiming no religious affiliation
Percentage of females by year:
1980 = 6.2%
1990 = 10.8%
2000 = 13.6%
2012 = 21.7%
Average yearly increase :
Percentage increase between 1980 - 2012 :
2012% - 1980% = ( 21.7% - 6.2%) = 15.5% increase over [(2012 - 1980)] = 32 years
15.5 % / 32 years = 0.484375% / year = 0.5%/year
b. Estimate the percentage of first-year college females who will claim no religious affiliation in 2030,
Given an average increase of 0.484375% / year
(2030 - 1980) = 50 years
Hence by 2030 ; ( 50 years × 0.484375%/year) = 24.218% will claim no religious affiliation.
=24.2% (nearest tenth)
In this exercise we have to use the percentage knowledge to calculate an estimate per year, in this way we find that;
A) [tex]0.5\%/year[/tex]
B) [tex]24.2\%[/tex]
Estimate the average yearly increase in the percentage of first-year college females claiming no religious affiliation. Percentage of females by year:
[tex]1980 = 6.2\%\\1990 = 10.8\%\\2000 = 13.6\%\\2012 = 21.7\%[/tex]
A) Average yearly increase can be caculeted by:
[tex]2012\% - 1980\% = ( 21.7\% - 6.2\%) = 15.5\% = 32 years \\15.5 \% / 32 years = 0.484375\% / year = 0.5\%/year\\[/tex]
B) Estimate the portion of first-old age institution of higher education woman the one will claim no religious association with an organization fashionable 2030, Given an average increase of:
[tex](2030 - 1980) = 50 years\\ ( 50 years * 0.484375\%/year) = 24.2\%[/tex]

What percent is equivalent to 3/10? A.) 0.3% B.) 3% C.) 10% D.) 30%
Answer: 0.3
Step-by-step explanation:
A percent that is equivalent to 3/10 is: D.) 30%.
What is a percentage?In Mathematics, a percentage is any number that is expressed as a fraction of hundred (100). This ultimately implies that, a percentage indicates the hundredth parts of any given number.
By multiplying both the numerator and denominator by a common number such as 10, we have the following:
3/10 × 10/10
30/100
30%
Based on the information provided, we can logically deduce that 30% is equivalent to 3/10. Therefore, the correct answer option is: D.) 30%.

The flanagans are having their fifth child. All of their childern are athletically gifted,so the youngest child is bound to be athletically gifted as well. Is this a deductive argument or inductive?
Answer: inductive argument.
Step-by-step explanation:
Deductive argument is a logical argument in which a conclusion is made upon the given premises which are assumed to be true.
inductive argument works on the basis of a series of observation and then bring it to frame a certain conclusion.
Here, Flanagans are considering the observation they made by previous children (i.e. they are athletically gifted) and applying the same on the new one by saying "youngest child is bound to be athletically gifted as well.".
So it is of-course an inductive argument.

The point (2,6) lies on the graph of the equation y = kx^2 - 3x Find the value of K
Answer:
k = 3Step-by-step explanation:
y = kx² - 3x
Since the points lie on the graph we can substitute the values of x and y that's
( 2 ,6) into the equation to find k.
We have
6 = (2)²k - 3(2)
6 = 4k - 6
4k = 6 + 6
4k = 12
Divide both sides by k
That's
[tex] \frac{4k}{4} = \frac{12}{4} [/tex]
We have the final answer as
k = 3Hope this helps you

Which pair of variables would most likely have a negative correlation?
A. the time spent driving in a car and the number of miles driven
B. the height of a dog in inches and the number of ounces of food the dog eats per day
C. the number of sit-ups completed and the number of calories burned during a workout
D. the time spent reading a book and the number of pages remaining to be read in the book
Answer: D
Step-by-step explanation:
The pair of variables that will most likely have a negative correlation are D. the time spent reading a book and the number of pages remaining to be read in the book.
Negative CorrelationThis means that the variables involved move in the opposite direction from each other. Means that as one variable increases, the other decreases and vice versa.If you spend a longer time reading a book, you would read more pages which would reduce the number of pages left to be read. The time taken to read the book is therefore negatively correlated with the number of pages left.
In conclusion, option D is correct.

Ashley has 9 pizzas .She is serving each person at a party 3/4 of a pizza.How many can she serve at the party?
Answer:
Ashley can serve 12 pieces of pizza in the party
Step-by-step explanation:
To solve this question we need to convert the 9 pizzas to decimal:
9 times 4 = 36. That is:
9 pizzas are equal to 36/4 of pizza (36/4 = 9)
As Ashley is serving 3/4 of a pizza she can serve:
36/4 ÷ 3/4 = 36/3 = 12
Ashley can serve 12 pieces of pizza in the party
