Which Function is equivalent to g(x) = x2 + 7x - 18?
A) g(x) = (x-9) (x+2)
B) g(x) = (x+9) (x-2)
C) g(x) = (x+6) (x-3)
D) g(x) = (x-6) (x+3)
The given equivalent function is g(x)=(x+9)(x-2). Therefore, option B is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given function is g(x)=x²+7x-18
Now, g(x)=x²+9x-2x-18
g(x)=x(x+9)-2(x+9)
g(x)=(x+9)(x-2)
Therefore, option B is the correct answer.

It takes Joan 2 times longer than Jane to file the reports. Together, they can file the reports in 8 minutes. How long would it take each woman to file the reports by herself?
It takes Jane _ minutes to complete the job.
It takes Joan _ minutes to complete the job.
Answer:
It takes Jane 2 2/3 minutes
It takes Joan 5 1/3 minutes
Step-by-step explanation:
let j = time it takes Jane
let 2j = time it take Joan
j + 2j = 8
3j = 8
j = 8/3 or 2/23
2j = 16/3 or 5 1/3

Find the area of the figure. (Sides meet at right angles.)
Answer:
90 cm^2
Step-by-step explanation:
Divide the rectangle and square into two separate figures and add them together at the end.
Top rectangle: We know that area of a rectangle is A=lw. Here, we see that w=5 cm. For the length, we add 4+5+4=13 (5 comes from the bottom square). So A=5(13)=65
Bottom square: Area of a square is A=s^2 where s=5 in this case, so A=5^2=25
Total Area: Add together two figure's area: A=65+25=90 cm^2
What percent of 51 is 65?
Answer:127.45
Step-by-step explanation:
Percentage solution with steps:
Step 1: We make the assumption that 51 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that $100\%=51$.
Step 4: In the same vein, $x\%=65$.
Step 5: This gives us a pair of simple equations:
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
Step 7: Taking the inverse (or reciprocal) of both sides yields
Therfore: 51% of 65 is 127.45

A given data set has a symmetrical shape.
Which statement is true about the data set?
(There are no attachments to this question.)
Answer: The mean is equal to the median.
Step-by-step explanation:
Median is the middle value of a given data set. In asymmetric distribution, the data on the left side of the median is equal to the data on the right side of the median. Therefore, the mean of that data is equal to the median of the symmetric distribution.
What is an equation of the line that passes through the points (8, 2) and
(7, 1)?
Answer:
y = x - 6
Step-by-step explanation:
the slope-intercept form for any line is y = mx + b, where m is the slope and b is the y-intercept.
now, let's calculate the slope:
1-2/7-8= -1/-1 = 1
here is the equation we currently have solved: y = x + b
now we have to solve for the y-intercept. to do this, we substitute one of the given points into the equation, and solve for b.
let's use (8, 2). in this ordered pair, the 8 is the x, and the 2 is the y.
2= 8 +b
2 -8=b
b=-6
and now we have our final equation!
y = x - 6

Use Heron's formula to find the area of the triangle. Round to the nearest square foot.
Side a = 4 feet
Side b=4 feet
Side c=1 feet
Answer:
A ≈ 2 ft²
Step-by-step explanation:
The area (A) of a triangle using Heron's formula is
A = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
where s is the semiperimeter and a, b , c the sides of the triangle.
s = [tex]\frac{a+b+c}{2}[/tex] = [tex]\frac{4+4+1}{2}[/tex] = [tex]\frac{9}{2}[/tex] = 4.5
Then
A = [tex]\sqrt{4.5(4.5-4)(4.5-4)(4.5-1)}[/tex]
= [tex]\sqrt{4.5(0.5)(0.5)(3.5)}[/tex]
= [tex]\sqrt{3.9375}[/tex]
≈ 1.9843...
= 2 ft² ( to the nearest square foot )

Answer:
Add all cups of sugar, which would be 20 divided it by 5( the number of students in the class) 20/5=4
Answer:
4
Step-by-step explanation:
Number of students - 5 (count the number of cup of sugar
Total number of sugar cups - 3+4+5+3+5 - 20
Number of cups of sugar each student got - 5/20

1.In a class of 45 pupils ,21play chess and 23 play cards and 5play both games
(a) find:
i. how many do not play any of the games .
ii. how many play chess only.
iii. how many play cards only .
(b). What is the probability of selecting a pupil who plays only one game?
Step-by-step explanation:
(a)
ii.
21 - 5 = 16 play only chess.
iii.
23 - 5 = 18 play only cards
5 play both.
that is 16+18+5 = 39 that play at least one of these games.
i.
so, 45 - 39 = 6 don't play any of these games.
(b)
we have 16+18 = 34 pupils out of 45 that play exactly one game.
so the probabilty to pick one of them is as usual
desired cases / total cases = 34/45 =
= 0.755555555... ≈ 0.76
