Answer:
The function g(x) = (x + 1)² is represented by the graph Y
Step-by-step explanation:
The question presents the graph of the function x² above
Therefore, for a function f(x) = x² at x = 0 y = 0
For function g(x) = (x + 1)² when x = 0 g(x) = 1 Satisfied by graph W and Y
Also we have g(x) = (x + 1)² = x² + 2·x + 1 or g(x) = f(x) + 2·x + 1
We find the minimum of the graph by differentiating and equating to zero as follows;
[tex]\frac{\mathrm{d} (x + 1)^{2}}{\mathrm{d} x} = 2x +2 = 0[/tex]
Therefor, the minimum is at x = -1 satisfied by only graph Y
Hence the graph that represents the function g(x) = (x + 1)² is the graph Y.

How does the volume of a square pyramid change if the base area is quadrupled and the height is reduced to 1/9 of its original size
Final answer:
The volume of a square pyramid changes by a factor of 4/27 when the base area is quadrupled and the height is reduced to 1/9 of its original size.
Explanation:
The volume of a square pyramid can be found using the formula:
Volume = (1/3) * Base Area * Height
If the base area is quadrupled, it means the new base area is 4 times the original.
If the height is reduced to 1/9 of its original size, it means the new height is 1/9 of the original.
Therefore, the change in volume can be calculated as:
Change in Volume = (1/3) * (4 * Original Base Area) * (1/9 * Original Height)
Simplifying the expression, we get:
Change in Volume = (4/27) * Original Volume

Final answer:
Two test scores that fulfill the inequality s ≥ 92 are 92 and 95, meaning that Jared can get an A on his report card with either of those scores.
Explanation:
The inequality s ≥ 92 represents the score (s) that Jared must earn on his test to get an A on his report card. Since the inequality includes the 'greater than or equal to' symbol (≥), two possible test scores that Jared could earn to get an A would be 92 and any other number greater than 92, for instance, 95.
Keenan has 28 CDs and 44 DVDs. What is the ratio of DVDs to CDs?
The ratio of DVDs to CDs in Keenan's collection is 11:7, after simplifying the original ratio of 44:28 by dividing both terms by their greatest common divisor, which is 4.
Keenan has a collection of 28 CDs and 44 DVDs. To find the ratio of DVDs to CDs, we divide the number of DVDs by the number of CDs. This gives us:
Ratio of DVDs to CDs = Number of DVDs / Number of CDs
Ratio of DVDs to CDs = 44 / 28
Now, we can simplify this by dividing both numbers by the greatest common divisor (GCD), which is 4 in this case:
44 / 4 = 11
28 / 4 = 7
So, the simplified ratio is 11:7.
Therefore, the ratio of DVDs to CDs in Keenan's collection is 11:7.

A rectangle has an area of (x - 17x + 72) square units. Since the area of a rectangle is determined using the formula, A =
kw, what could be the length and width of the rectangle?
length = (x - 8) units and width = (x - 9) units
length = (x + 9) units and width = (x + 8) units
length = (x-6) units and width= (x - 12) units
length = (x + 12) units and width = (x + 6) units
Answer:
Step-by-step explanation:
x² - 17x + 72 = 0
Sum = -17
Product = 72
Factor = 8 , 9
x² - 17x + 72 = 0
x² - 8x -9x + (-8)*(-9) = 0
x(x - 8) -9(x -8) = 0
(x - 8 ) (x - 9) = 0
Length = (x - 8) units
Width = (x - 9) units

Which has a greater volume? Cylinder A:r= 3m, h=1.2m cylinder B: d=4m, h=2.5m round your answer for the nearest tenths
Cylinder A has a greater volume of approximately [tex]\( 33.9 \, \text{cubic meters} \)[/tex].
To compare the volumes of the two cylinders, we'll use the formula for the volume of a cylinder, which is:
[tex]\[ V = \pi \times r^2 \times h \][/tex]
Let's calculate the volumes step by step for Cylinder A and Cylinder B:
Cylinder A:
Given:
- Radius [tex](\( r \)) = 3m[/tex]
- Height [tex](\( h \)) = 1.2m[/tex]
Using the formula:
[tex]\[ V_A = \pi \times (3^2) \times 1.2 \][/tex]
[tex]\[ V_A = \pi \times 9 \times 1.2 \][/tex]
[tex]\[ V_A = 10.8\pi \, \text{cubic meters} \][/tex]
Cylinder B:
Given:
- Diameter [tex](\( d \)) = 4m[/tex] (so, \( [tex]r = \frac{d}{2} = \frac{4}{2} = 2 \) m[/tex])
- Height [tex](\( h \)) = 2.5m[/tex]
Using the formula:
[tex]\[ V_B = \pi \times (2^2) \times 2.5 \][/tex]
[tex]\[ V_B = \pi \times 4 \times 2.5 \][/tex]
[tex]\[ V_B = 10\pi \, \text{cubic meters} \][/tex]
Now, to determine which cylinder has the greater volume, we compare [tex]\( V_A \)[/tex] and [tex]\( V_B \)[/tex]:
[tex]\[ V_A = 10.8\pi \, \text{cubic meters} \][/tex]
[tex]\[ V_B = 10\pi \, \text{cubic meters} \][/tex]
Since [tex]\( 10.8\pi > 10\pi \)[/tex], Cylinder A has the greater volume.
Therefore, Cylinder A has a greater volume, approximately [tex]\( 10.8\pi \)[/tex]cubic meters.
Let's calculate the approximate numerical value for [tex]\( 10.8\pi \)[/tex]:
[tex]\[ 10.8\pi \approx 10.8 \times 3.14 \approx 33.912 \][/tex]
Complete correct question:
Which has a greater volume?
Cylinder A: r = 3m, h = 1.2m.
Cylinder B: d = 4m, h = 2.5m.
Round your answer to the nearest tenth.
Cylinder A has a greater volume.
To find the volume of a cylinder, we use the formula:
[tex]\[ V = \pi r^2 h \]For Cylinder A:- Radius \( r = 3 \) meters- Height \( h = 1.2 \) meters\[ V_A = \pi (3)^2 \times 1.2 \]\[ V_A = \pi \times 9 \times 1.2 \]\[ V_A = 10.8 \pi \][/tex]
For Cylinder B:
[tex]- Radius \( r = \frac{d}{2} = \frac{4}{2} = 2 \) meters- Height \( h = 2.5 \) meters\[ V_B = \pi (2)^2 \times 2.5 \]\[ V_B = \pi \times 4 \times 2.5 \]\[ V_B = 10 \pi \]Now, let's compare the volumes:\[ V_A = 10.8 \pi \]\[ V_B = 10 \pi \][/tex]
Since [tex]\( 10.8 \pi > 10 \pi \)[/tex], Cylinder A has a greater volume.
Rounded to the nearest tenth, the volume of Cylinder A is approximately 33.9 cubic meters, and the volume of Cylinder B is approximately 31.4 cubic meters.

Help me please find the area of the room
Answer:
Cut the room into a rectangle and a trapezoid vertically. Then just use the rectangle and trapezoid area formulas to solve.
Step-by-step explanation:
It should work because this is how I find the area of most irregular shapes.
Answer:
To find the area you would first break the shape down into smaller regular shapes. In this case it would be a rectangle and trapezium. Then the next step to working out the area is to work out the area of one of the shapes. In this example i would start with the rectangle as it would be easier. The formula for the area of the rectangle would be length multiplied by the width. Then hold on to the answer. After you would work out the area of the trapezium. The formula for the area of a trapezium is: [tex]\frac{a+b}{2} *height[/tex]. To work this out you would add the lengths of the top line and the bottom line and divide them by 2. Then you would multiply that by the height of the trapezium. After you would add the area of the rectangle and the area of the trapezium and this will give you the total area.
1) Divide the shape into smaller regular shapes.
2) Find the area of the rectangle.
3) Find the area of the trapezium.
4) Add the two areas together.

Answer:
2 1/2
Step-by-step explanation:
If you do the step by step calculation:
Step 1: Simplify both sides of the equation.
2(12+2x+15+2x)=74
(2)(12)+(2)(2x)+(2)(15)+(2)(2x)=74(Distribute)
24+4x+30+4x=74
(4x+4x)+(24+30)=74(Combine Like Terms)
8x+54=74
8x+54=74
Step 2: Subtract 54 from both sides.
8x+54−54=74−54
8x=20
Step 3: Divide both sides by 8.
8x divide by 8 and that is 20 divided by 8
leaves you with the answer 5/2.

Explanation:
Michael is training for a marathon and plans to run 8 miles in his first week. The appropriate path for him would depend on several factors including scenery, difficulty level, and whether the path is traffic-free. A key aspect of marathon training as illustrated through the personal story shared is a gradual increase in mileage and a lifestyle change towards constant movement. Michael's marathon training should ensure that his 8 miles are manageable and reflect the incremental changes in habits he's aiming for.
When selecting a path, Michael might consider one that is reflective of the marathon environment, which could include terrain similar to the race he plans to participate in, or he might choose a path known for its relaxing scenery to make the run enjoyable and maintain motivation. Regardless of the exact path taken, the focus should be on building endurance through consistent and enjoyable running experiences.
Which statement is true about the effect of the 2-page introduction chapter?
The outlier of 2 increases the median page count.
The outlier of 2 increases the mean page count.
The outlier of 2 decreases the median page count.
The outlier of 2 decreases the mean page count.
Answer:
D
Step-by-step explanation:
The outlier of 2 decreases the mean page count.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
If the outlier is included in the calculation of the median and mean, then it will affect the measures of central tendency.
However, if the outlier is excluded from the calculation, then it will not affect the measures of central tendency.
If the 2-page introduction chapter is an outlier on the higher side of the distribution, the outlier of 2 increases the mean page count more than the median page count.
If the 2-page introduction chapter is an outlier on the lower side of the distribution, the outlier of 2 decreases the mean page count more than the median page count.
therefore, The outlier of 2 decreases the mean page count.

Ted borrowed $100 from 2 years at a 10% interest rate. How much interest will he pay on the loan? What will be the total amount due at the end of the loan?
Answer:
Interest = $20
Amount due = $120
Step-by-step explanation:
This is a Simple Interest problem. Simple interest is given as:
I = (P * R * T) / 100
Where I = interest
P = principal or amount loaned
R = rate of interest
T = time elapsed
Ted borrowed $100 from 2 years at a 10% interest rate.
This means that P = $100, R = 10%, T = 2 years.
Hence, the interest will be:
I = (100 * 10 * 2) / 100
I = 2000 / 100
I = $20
The interest after two years will be $20.
Therefore, the total amount due at the end of the loan is:
A = P + I
A = 100 + 20 = $120
The amount due is $120.
