2. Irene wants to list the factors for 88. She
writes 2, 4, 8, 11, 22, 44, and 88. Is Irene
correct? Explain.

Answers

Irene's list of factors for the number 88 is almost correct, but she forgot to include the number 1.

Irene wants to list the factors for 88 and she writes 2, 4, 8, 11, 22, 44, and 88. To verify if Irene is correct, we need to identify all of the numbers that can evenly divide 88 without leaving a remainder. Starting with the number 1, which is a factor of every number:

1 x 88 = 88, so 1 and 88 are factors.

2 x 44 = 88, so 2 and 44 are factors.

4 x 22 = 88, so 4 and 22 are factors.

8 x 11 = 88, so 8 and 11 are factors.

Since there are no other numbers between 1 and 88 that can multiply together to equal 88, the list that Irene wrote appears to be missing the number 1.

Therefore, Irene's list is almost correct, but for it to be complete, it should include the number 1. The full list of factors for the number 88 should be 1, 2, 4, 8, 11, 22, 44, 88.

The function f is such that f(x) = x^2 – 2x + 3
Solve f(x) = 27

(The bottom question in the photo)

Answers

Answer:

x = - 4, x = 6

Step-by-step explanation:

Given

f(x) = x² - 2x + 3 and f(x) = 27, then equating the 2 gives

x² - 2x + 3 = 27 ( subtract 27 from both sides )

x² - 2x - 24 = 0 ← in standard form

Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 2)

The factors are - 6 and + 4, since

- 6 × 4 = - 24 and - 6 + 4 = - 2, thus

(x - 6)(x + 4) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 4 = 0 ⇒ x = - 4

f(x)= 27

x^2 -2x+3=27

×^-2x+3-27=0

x^2x-24=0

(x-6)(x-4)=0

x-6=0 or ×-4=0

×=6or ×=4

Answers

Option B is correct. The required composite function where f(g(x)) is x is f (x) = StartFraction 2 Over x EndFraction and g (x) = StartFraction 2 Over x EndFraction

Composite functions are functions written inside another function e.g f(g(x))

Given the expressions

f(x) = 2/x

g(x) = 2/x

We are to find the composite function f(g(x))

f(g(x)) = f(2/x)

f(2/x) =  (2/(2/x))

f(2/x)  = 2 * x/2

f(2/x) = x

Hence the required composite function where f(g(x)) is x is f (x) = StartFraction 2 Over x EndFraction and g (x) = StartFraction 2 Over x EndFraction

[tex]1. \( (f \circ g)(x) = \frac{1}{x^2} \)\\2. \( (f \circ g)(x) = x \)\\3. \( (f \circ g)(x) = -x \)\\4. \( (f \circ g)(x) = \frac{1}{4}x - 1 \)[/tex]

let's break down each pair of functions and find their composition:

1. For [tex]\( f(x) = x^2 \) and \( g(x) = \frac{1}{x} \):[/tex]

  To find [tex]\( (f \circ g)(x) \)[/tex], we substitute [tex]\( g(x) \) into \( f(x) \):[/tex]

  [tex]\[ (f \circ g)(x) = f(g(x)) = f\left(\frac{1}{x}\right) = \left(\frac{1}{x}\right)^2 = \frac{1}{x^2} \][/tex]

  So, [tex]\( (f \circ g)(x) = \frac{1}{x^2} \).[/tex]

2. For [tex]\( f(x) = \frac{2}{x} \) and \( g(x) = \frac{2}{x} \):[/tex]

  Here, [tex]\( (f \circ g)(x) = f(g(x)) = f\left(\frac{2}{x}\right) \).[/tex]

  When you substitute [tex]\( \frac{2}{x} \) into \( f(x) \),[/tex]  you get:

 [tex]\[ (f \circ g)(x) = f\left(\frac{2}{x}\right) = \frac{2}{\frac{2}{x}} = x \][/tex]

  So, [tex]\( (f \circ g)(x) = x \).[/tex]

3. For [tex]\( f(x) = \frac{x-2}{3} \) and \( g(x) = 2 - 3x \):[/tex]

 [tex]\( (f \circ g)(x) = f(g(x)) = f(2 - 3x) \).[/tex]

  Substituting  [tex]\( 2 - 3x \) into \( f(x) \),[/tex]we get:

 [tex]\[ (f \circ g)(x) = f(2 - 3x) = \frac{(2 - 3x) - 2}{3} = \frac{-3x}{3} = -x \][/tex]

  So, [tex]\( (f \circ g)(x) = -x \).[/tex]

4. For [tex]\( f(x) = \frac{1}{2}x - 2 \) and \( g(x) = \frac{1}{2}x + 2 \):[/tex]

  Here, [tex]\( (f \circ g)(x) = f(g(x)) = f\left(\frac{1}{2}x + 2\right) \).[/tex]

  When you substitute [tex]\( \frac{1}{2}x + 2 \) into \( f(x) \),[/tex] you get:

 [tex]\[ (f \circ g)(x) = f\left(\frac{1}{2}x + 2\right) = \frac{1}{2}\left(\frac{1}{2}x + 2\right) - 2 = \frac{1}{4}x + 1 - 2 = \frac{1}{4}x - 1 \][/tex]

  So, [tex]\( (f \circ g)(x) = \frac{1}{4}x - 1 \).[/tex]

So, summarizing:

1. For [tex]\( f(x) = x^2 \) and \( g(x) = \frac{1}{x} \), \( (f \circ g)(x) = \frac{1}{x^2} \).[/tex]

2. For [tex]\( f(x) = \frac{2}{x} \) and \( g(x) = \frac{2}{x} \), \( (f \circ g)(x) = x \).[/tex]

3. For [tex]\( f(x) = \frac{x-2}{3} \) and \( g(x) = 2 - 3x \), \( (f \circ g)(x) = -x \).[/tex]

4. For [tex]\( f(x) = \frac{1}{2}x - 2 \) and \( g(x) = \frac{1}{2}x + 2 \), \( (f \circ g)(x) = \frac{1}{4}x - 1 \).[/tex]

determine whether each equation below does or does not represent a proportional relationship. support your answer using either a table or a graph

equation A: y = x
equation B: y = x+2​

Answers

Answer:

As the ratio for all the points on the equation y = x is same. Hence, the equation y = x REPRESENTS a proportional relationship.As the ratio for all the points on the equation y = x+2 is not same. Hence, the equation y = x + 2 DOES NOT REPRESENT a proportional relationship.

Step-by-step explanation:

                                        Solving equation A: y = x

Let us consider the given equation A:

                                                      y = x

Putting x = 1 in y = x

y = x

y = 1    ∵ x = 1

Hence, (1, 1) is the ordered pair of  y = x

Putting x = 2 in y = x

y = x

y = 2    ∵ x = 2

Hence, (2, 2) is the ordered pair of  y = x

Putting x = 3 in y = x

y = x

y = 3    ∵ x = 3

Hence, (3, 3) is the ordered pair of  y = x

Putting x = 4 in y = x

y = x

y = 4    ∵ x = 4

Hence, (4, 4) is the ordered pair of  y = x

Putting x = 5 in y = x

y = x

y = 5    ∵ x = 5

Hence, (5, 5) is the ordered pair of y = x

Lets us consider all the ordered pairs i.e. (1, 1), (2, 2), (3, 3), (4, 4) and (5, 5) to make a table for y = x.

y                 x

2                 2

3                 3

4                 4

5                 5

As from the table, lets take the ratio of every point i.e. y/x

For (1, 1), the ratio will be y/x ⇒ 1/1 = 1For (2, 2), the ratio will be y/x ⇒ 2/2 = 1For (3, 3), the ratio will be y/x ⇒ 3/3 = 1For (4, 4), the ratio will be y/x ⇒ 4/4 = 1For (5, 5), the ratio will be y/x ⇒ 5/5 = 1

Hence, the ratio for all the points on the equation y = x is same. Hence, the equation y = x REPRESENTS a proportional relationship. Please also check the graph in attached figure a.

                                          Solving equation A: y = x +2

Let us consider the given equation A:

                                                         y = x + 2    

Putting x = 1 in y = x + 2

y = x + 2

y = 1 + 2 ⇒ 3  ∵ x = 1

Hence, (1, 3) is the ordered pair of y = x + 2

Putting x = 2 in y = x + 2

y = x + 2

y = 2 +2 ⇒ 4   ∵ x = 2

Hence, (2, 4) is the ordered pair of y = x + 2

Putting x = 3 in y = x + 2

y = x + 2

y = 3 + 2 ⇒ 5    ∵ x = 3

Hence, (3, 5) is the ordered pair of  y = x + 2

Putting x = 4 in y = x + 2  

y = x + 2  

y = 4 + 2 ⇒ 6   ∵ x = 4

Hence, (4, 6) is the ordered pair of  y = x + 2

Putting x = 5 in y = x + 2

y = x + 2

y = 5 +2 ⇒ 7    ∵ x = 5

Hence, (5, 7) is the ordered pair of y = x + 2

Lets us consider all the ordered pairs i.e. (1, 3), (2, 4), (3, 5), (4, 6) and (5, 7) to make a table for y = x + 2.

y                 x + 2

Write 48.4% as a decimal and as a simplified fraction

Answers

Answer:

121/250

Step-by-step explanation:

Look at the picture

Final answer:

The decimal equivalent of 48.4% is 0.484 and the simplified fraction equivalent is 242/500.

Explanation:

To convert 48.4% to a decimal, you simply divide the percentage by 100. Therefore, 48.4% as a decimal would be 0.484.

To write 48.4% as a simplified fraction, we start with the fraction that percentage represents, which is 48.4 / 100. However, both these numbers are divisible by 2 which simplifies it to 242 / 500. That is the simplest form of the fraction represented by 48.4%.

Step-by-step explanation:

Find the value of c where p = 0.

0 = c² + 2c − 5

6 = c² + 2c + 1

6 = (c + 1)²

±√6 = c + 1

c = -1 ± √6

c must be positive, so c = -1 + √6 ≈ 1.45.  So John must sell at least 2 candy bars to make a profit.

We can also show this using trial and error.

If c = 0, then p = -5

If c = 1, then p = -2

If c = 2, then p = 3

4. A case of eggs contains 15 dozen eggs. What is the AP unit cos
egg if a case of eggs costs $34.20?

Answers

Answer:

.19 cent per egg

Step-by-step explanation:

15*12=180

34.20/180= .19

Final answer:

The unit cost per egg is $0.60 when a case of eggs costs $34.20.

Explanation:

The unit cost per egg is $0.60.

To find the cost per egg when a case contains 15 dozen eggs costing $34.20, you first calculate the cost per dozen by dividing the total cost by the number of dozens (15). Then, you divide the cost per dozen by 12 to find the cost per egg. In this case, $34.20 divided by 15 gives $2.28 cost per dozen. Finally, $2.28 divided by 12 equals $0.60, so each egg costs $0.60.

A bicycle wheel with the diameter 70cm is making 25 revolutions while travelling. Find the distance covered by the bicycle

Answers

Final answer:

The total distance covered by the bicycle is calculated using the circumference of the wheel and the number of revolutions made. With a wheel diameter of 70 cm, the total distance comes to approximately 55.0 meters after 25 revolutions.

Explanation:

The question involves calculating the distance covered by a bicycle wheel making a certain number of revolutions. Given that the diameter of the wheel is 70 cm, we can find the circumference, which is the distance the wheel covers per revolution. The circumference is equal to \\(\pi\cdot d\\), where \\(d\\) is the diameter. Substituting the given diameter:

Circumference = \\(\pi \times 70 \\text{cm}\\)

Since the wheel makes 25 revolutions, the total distance covered (\\em{D}}) can be found by multiplying the circumference by the number of revolutions:

Total distance covered = Circumference \\(\times\\) Number of revolutionsTotal distance covered = \\(\pi \times 70 \\text{cm} \times 25\\)

Thus, the bicycle covers a distance of \\(25 \times \pi \times 70 \\text{cm}\\), or \\(25 \times \pi \times 0.7 \\text{m}\\), since 100 cm equals 1 meter.

To find the exact value, you would calculate:

Total distance covered = \\(25 \times \pi \times 0.7 \\text{m} \\approx 55.0 \\text{meters}\\)

A) k=2
B) k=1/2
C) k= -2
D) k= -1/2

Answers

A) k=2 is the right answer

Step-by-step explanation:

The downward funtion transformation is defined as:

f(x) => f(x)-b where b is an integer.

Given

[tex]f(x) = (0.5)^x[/tex]

And

[tex]g(x) = (0.5)^x-k[/tex]

It is also given that g(x)  is obtained by shifting function f 2 units downward

We will apply the transformation to function f to find the value of k.

So,

Shifting f(x) 2 units downward

we will get

[tex]g(x) = (0.5)^x-2[/tex]

comparing with [tex]g(x) = (0.5)^x-k[/tex] we get that

k = 2

Notice that our sphere has a radius of 7 inches so plugging into the formula, we have [tex](\frac{4}{3})(\pi)(7 in.)^{3}[/tex].

Start by simplifying the exponent. (7 in.)³ is equal to 7 inches x 7 inches x 7 inches or 343 in³ so we have [tex](\frac{4}{3}) (343 in.^{3})(\pi)[/tex].

Next, 4 x 343 is 1,372 which gives us [tex]\frac{1,372\pi }{3}[/tex]. Notice that 1,372 doesn't divide by 3 so this is our final answer for the volume of the sphere.

Today Robbie is carrying his history textbook and his lunch in his backpack. If the history textbook weighs 2 5/6 pounds and his lunch weighs 1 2/3 pounds, how much weight is in Robbie's backpack?

Answers

Final answer:

To find the total weight in Robbie's backpack, the weights of the history textbook (2 5/6 pounds) and lunch (1 2/3 pounds) are added, resulting in a total of 4 1/2 pounds.

Explanation:

The question involves finding the total weight of items in Robbie's backpack: a history textbook and his lunch. The history textbook weighs 2 5/6 pounds and his lunch weighs 1 2/3 pounds.

To find the total weight, we first convert the mixed numbers into improper fractions for easier addition. The history textbook's weight as an improper fraction is (2×6)+5 = 17/6 pounds. The lunch's weight is (1×3)+2 = 5/3 pounds.

Adding these two fractions gives us:

   17/6 + 5/3 = 17/6 + 10/6 = 27/6 pounds

Since 27/6 simplifies to 4 1/2 pounds, the total weight in Robbie's backpack is 4 1/2 pounds.

Answer:

8

Step-by-step explanation:

To solve this, you can add 2/5 b to both sides of the equation. You now have 3 + 5/5 (or 1) b = 11. => 3 + b = 11 => Now, subtract 3 from both sides, and you have b = 11 - 3, and then b = 8.

Step-by-step explanation:

3 + 2/5 b =11 - 2/5 b (this is the given question is it?)

2/5 b + 2/5 b= 11 - 3 (like terms together, you transpose -2/5b to the other side as shown.)

2b+2b = 8 ( at that stage you would find t

5 hat 5 is the common value to go into 5 itself, as shown.

4b = 8 ( you just add 2b + 2b to have 4b)

5

4b = 8 ( at that point you cross multiply

5 1 as shown)

4b = 8 × 5 ( simple math as shown)

4b = 40 ( you multiply 8 × 5 to obtain 40)

b =10 you can prove that. Thank you.

Answer:

D.  120°

Step-by-step explanation:

Interior angles of a rhombus always add up to 360 degrees. Thus we can set up an equation:

g+g+2g+2g=360

Now let's combine all the like terms (g's).

6g=360

Now we divide both sides by six to isolate g.

g=60

We can now substitute g into angle B, to find its value.  

2g

2(60)

120

Thus, the measure of angle B is 120, or option D.

Which equation represents the line that is perpendicular to graph of 4x+3y=9 and passes through (-2,3)

Answers

Final answer:

The equation of the line which is perpendicular to the line 4x + 3y = 9 and passes through the point (-2,3) is y = 3/4x + 4.5.

Explanation:

The original equation is 4x + 3y = 9. To start off, rewrite this equation in slope-intercept form (y = mx + b) to help find the slope. After isolating y, the equation turns into y = -4/3x + 3. So, the slope of the original line is -4/3.

Perpendicular lines have slopes which are negative reciprocals of each other, thus the slope of the line perpendicular to the given line is the negative reciprocal of -4/3, which is 3/4 (m = 3/4 for the second line)

We are also given that the line we are looking for passes through the point (-2,3). Use the point-slope form of a line, given by y - y1 = m(x - x1), where m is the slope, and (x1, y1) is the given point. Substituting in the values, you get:

y - 3 = 3/4(x - -2).

Simplifying the equation, we find that the line perpendicular to 4x + 3y = 9 and passing through (-2, 3) is y = 3/4x + 4.5

Step-by-step explanation:

find the slope of the line that is horizontal and passes through the point (3,-4). m= ?

Answers

Answer:  [tex]m=0[/tex]

Step-by-step explanation:

The slope can be calculated with this formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Notice that the formula shows the change in "y" for a unit change in "x"  on the line.

In order to solve this exercise, it is important to remember that:

1. If a line is increasing, then its slope is positive.

2. If a line is decreasing, then its slope is negative.

3. If the line is horizontal, its slope is zero.

4. If the line is vertical, it has no slope.

Therefore, since the given line that passes through the point [tex](3,-4)[/tex], is horizontal, its slope is:

[tex]m=0[/tex]
