Which values of x would make a polynomial equal to zero if the factors of the
polynomial were (x-3) and (x-7)?

Answers

Answer 1

Answer:

x = 3 and x = 7

Step-by-step explanation:

Equate the product of the factors to zero, that is

(x - 3)(x - 7) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 7 = 0 ⇒ x = 7

Answer 2

Final answer:

To find the values of x that make a polynomial equal to zero, set each factor equal to zero and solve for x. The values of x that would make the polynomial equal to zero are x = 3, and x = 7.

Explanation:

To find the values of x that make a polynomial equal to zero, you need to set each factor equal to zero and solve for x.

Set x-3=0 and solve for x to get x=3.

Set x-7=0 and solve for x to get x=7.

Therefore, the values of x that would make the polynomial equal to zero are x = 3 and x = 7.

How much more area does a medium pizza with a 14 in. diameter have
than a small pizza with a 12 in diameter? Use the r key on your calculator
to approximate a Round your answer to the nearest square inch.

Answers

Final answer:

The medium pizza with a 14-inch diameter has approximately 41 square inches more area than the small pizza with a 12-inch diameter, using the formula for the area of a circle, πr², where r is the radius (half of the diameter).

Explanation:

The subject of this question is area comparison between two circles, which is a topic in Mathematics. The areas of the two pizzas (which we can represent as circles) can be found using the formula for the area of a circle, which is πr^2, where r is the radius (half of the diameter).

For the medium pizza, the diameter is 14 inches, so the radius is 7 inches. The area is thus π*(7)^2 = 153.94 square inches. For the small pizza, the diameter is 12 inches, so the radius is 6 inches. The area is thus π*(6)^2 = 113.10 square inches.

So, the medium pizza has 153.94 - 113.10 = 40.84 square inches more area than the small pizza. Rounded to the nearest square inch, the medium pizza has approximately 41 square inches more area than the small pizza.

The coordinates are (3,6) (3,12) (6,18) (15,12).

Hope this helps!
Final answer:

If polygon ABCD with vertices A (1, 2), B (1,4), C(2,6), and D (5, 4) is dilated by a factor 3, the coordinates of the dilated polygon are A' (3, 6), B' (3, 12), C' (6, 18), and D' (15, 12).

Explanation:

When a polygon is dilated by a scale factor, all the coordinates of its vertices are multiplied by that scale factor. In this case, the scale factor is 3. Thus, we should multiply the x and y coordinates of each vertex by 3.

Let's calculate:

Vertex A (1, 2) dilated by scale factor 3 becomes A' (1*3, 2*3) => A' (3, 6)Vertex B (1,4) becomes B' (1*3, 4*3) => B' (3, 12)Vertex C (2,6) becomes C' (2*3, 6*3) => C' (6, 18)Vertex D (5, 4) becomes D' (5*3, 4*3) => D' (15, 12)

So, the coordinates of the dilated polygon ABCD are A' (3, 6), B' (3, 12), C' (6, 18), and D' (15, 12).

Two fair dice are rolled 4 times and the sum of the numbers that come up are recorded. Find the probability of these events. A) the sun is 5 on each of the four rolls. B) the sun is 5 exactly three times in the four rolls.

Answers

Answer:

See below in bold.

Step-by-step explanation:

A.  On one roll the possible ways to get a sum of 5 is (2,3, ) and (4, 1).

There are 36 possible outcomes from the one roll of the 2 dice.

So the probability of getting  a sum of 5 on one roll =  2/36 = 1/18.

So the probability of 5 on 4 rolls = (1/18)^4

= 1/104976.

B.  

The probability of the first 3 rolls being a 5 and the last one being not 5

= (1/18)^3 * (17/18)

= 17/104976

There are 4 ways to  pick 3 out of 4 so the required probability

=  4 * 17/104976

= 68/104976.

Final answer:

The detailed answer explains the probability of rolling specific sums with two fair dice in four rolls, covering events A and B.

Explanation:

The Probability of Rolling Sums with Two Fair Dice

For event A, the probability of getting a sum of 5 on each of the four rolls is (4/36)⁴.

For event B, the probability of getting a sum of 5 exactly three times in the four rolls is 4*(4/36)³*(32/36).

Answers

Answer:

A.  The angle measures are 30°, 60°, and 90°.

on edge

Step-by-step explanation:

Final answer:

If the question provides the angles of a triangle as 30°, 60°, and 90°, or 45°, 45°, and 90°, we are dealing with a right triangle. Depending on the measures of the angles, the triangle can be classified as either a 30-60-90 triangle or a 45-45-90 isosceles right triangle. Without sufficient information, the exact measures of the angles cannot be determined.

Explanation:

When considering a triangle with angle measures provided as options, we recall the fundamental property that the sum of internal angles in any triangle is 180 degrees. The question presents three possible sets of angle measures:

30°, 60°, and 90°45°, 45°, and 90°A 90° angle, with unspecified other angles

Both of the first two options include a 90° angle, indicating that we are dealing with a right triangle. Right triangles have specific properties and can be classified as either 30-60-90 or 45-45-90 triangles, depending on the measures of the other two angles. A 30-60-90 triangle has angles in the ratio of 1:2:√3, and a 45-45-90 triangle, also called an isosceles right triangle, has two angles of 45° each. The third option implies insufficient information to determine the exact measures of all angles.


Given the two sets:

Which of the following is a true statement?

4 ∈ B
A ⊆ B
A is an infinite set
∅ ∉ B

Answers

Answer:

Step-by-step explanation:

B and c

Final answer:

The correct statement is that set A is a subset of set B, as they contain exactly the same elements. The statements about set B containing the number 4 and set A being infinite are false, while the empty set is a subset of every set, including B.


The correct statement regarding the sets A = {1, 2, 3} and B = {3, 2, 1} is A ⊆ B. This is because every element in set A is also in set B, regardless of the order the elements are listed. Sets are collections of distinct objects and their definition does not depend on the order of the elements. Therefore, A and B have exactly the same members, making them equal sets, and conversely, every set is a subset of itself. This can also be seen as both sets having the same cardinality, which is the number of members in a set, and for both A and B, this is 3.

As for the other statements, the number 4 is not an element of set B (4 ∈ B), the set A is not infinite since it has a finite cardinality of 3 (A is not an infinite set), and the empty set is actually a subset of every set, including B ⊂ \⊆cannot be true.

1. A retirement account is opened with an initial deposit of $8,500 and earns 8.12% interest compounded monthly. What will the account be worth in 20 years? What if the deposit were compounded monthly with simple interest? Could you see the situation in a graph? From what point one is better than the other?

Answers

Answer:

Part A) [tex]\$42,888.48[/tex]  

Part B) [tex]A=\$22,304[/tex]

Part C) The graph in the attached figure

Step-by-step explanation:

Part A) What will the account be worth in 20 years?

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]t=20\ years\\ P=\$8,500\\ r=0.0812\\n=12[/tex]  

substitute in the formula above  

[tex]A=8,500(1+\frac{0.0812}{12})^{12*20}[/tex]  

[tex]A=8,500(1.0068)^{240}[/tex]  

[tex]A=\$42,888.48[/tex]  

Part B) What if the deposit were compounded monthly with simple interest?  

we know that

The simple interest formula is equal to

[tex]A=P(1+rt)[/tex]

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

[tex]t=20\ years\\ P=\$8,500\\r=0.0812[/tex]

substitute in the formula above

[tex]A=8,500(1+0.0812*20)[/tex]

[tex]A=\$22,304[/tex]

Part C) Could you see the situation in a graph? From what point one is better than the other?

Convert the equations in function notation

[tex]A(t)=8,500(1.0068)^{12t}[/tex] ------> equation A

[tex]A(t)=8,500(1+0.0812t)[/tex]  -----> equation B

using a graphing tool  

see the attached figure  

Observing the graph, from the second year approximately the monthly compound interest is better than the simple interest.

Final answer:

The retirement account will be worth $27,627.24 after 20 years with compound interest and $23,180 with simple interest. Compound interest grows at a faster rate and becomes better than simple interest when the compounding periods are more frequent.

Explanation:

To calculate the value of the retirement account after 20 years with compound interest, we can use the formula A = P(1 + r/n)^(nt), where A is the final amount, P is the principal deposit, r is the interest rate, n is the number of times compounded per year, and t is the number of years. In this case, P = $8,500, r = 8.12%, n = 12 (monthly compounding), and t = 20. Plugging in these values, we get A = $8,500(1 + 0.0812/12)^(12*20) = $27,627.24.

If the deposit were compounded monthly with simple interest, we can use the formula A = P + (P*r*t), where A is the final amount, P is the principal deposit, r is the interest rate, and t is the number of years. In this case, P = $8,500, r = 8.12%, and t = 20. Plugging in these values, we get A = $8,500 + ($8,500 * 0.0812 * 20) = $23,180.

To compare the two situations on a graph, we can plot the value of the retirement account over time for both compound and simple interest. We would see that the compound interest account grows at a faster rate and reaches a higher value compared to the simple interest account. Compound interest becomes better than simple interest when the compounding periods are more frequent, as it allows the interest to be reinvested more often and generate additional earnings.

Which of the following rational functions is graphed below?

Answers

Answer:

Step-by-step explanation:

Hi there!

This is a Rational Function. The process of graphing it takes a lot more hard work than graphing other functions like linear, quadratic, modulus, and so on.

Here a list on how to proceed

First

1) Find the point of intersections by calculating the zeros of the function on the Numerator. In this case, we just have a 1 on top, so our graph won't intercept x-axis.

2) Calculate the vertical asymptotes by calculating the zeros of the function in the denominator, x²+4x=0 S=(0,-4) on green on the graph below.

3) Construct the table of values for x, and y

4) Trace the graph

By analyzing the asymptotes on the graph, we conclude that the correct option is C.

How to determine the rational function graphed?

To do it, we need to see at which x-values we have asymptotes. These are the values of x where the denominator becomes equal to zero.

Here we can see that we have asymptotes at:

x = 0 and x = -4

Then the denominator must be a polynomial with roots at x = 0 and x = -4, this is written as:

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

So the rational function is something like:

[tex]f(x) = \frac{1}{x*(x + 4)}[/tex]

So the correct option is C.

What is the center of the circle shown below?

Answers

Answer:

B is the center of the circle.

Step-by-step explanation:

Given is a circle in the picture.

A is the point on the circle.

Y is another point on the circle

AY is hence the chord

B is equidistant from the circumference

B is the center of the circle.

Point B is established as the center of the circle because it is equidistant from the circumference. This property defines B as the central point from which all points on the circle are equally distant, confirming its role as the circle's center.

In the given scenario, the information provided indicates that point B is equidistant from the circumference of the circle. This property characterizes point B as the center of the circle.

To articulate this differently, since B is equidistant from any point on the circle, it serves as the central point from which all points on the circle are equally distant.

Therefore, B is unequivocally identified as the center of the circle. This conclusion is drawn from the fact that the center of a circle possesses the unique property of being equidistant from all points on its circumference.

Determine the input that would give an output value of 2/3

Answers

Answer:

x = 19

Step-by-step explanation:

Question: find x such that f(x) = 2/3

Given f(x) = (-1/3) x + 7

equate the value of f(x) to be 2/3

hence,

(2/3) = (-1/3)x + 7 (multiply both sides by 3)

(3) (2/3)  = (3) (-1/3)x + (3) 7

2 = -x + 21

x = 21 - 2

x = 19

So to get the output value 2/3 we will input x = 19

What is a function?

A mathematical relationship from a set of inputs to a set of outputs is called a function.

What are equations?

An equation is a mathematical statement which equate two algebraic expressions. An equation has an equal to (=) sign in between the expression.

How to find the input that would give an output value of 2/3 ?The function used here is f(x) = [tex]-\frac{x}{3} + 7[/tex]

Clearly, all the values of x and f(x) are satisfying it.

Now, the output is given as 2/3.

So, we can write,

[tex]\frac{2}{3} = -\frac{x}{3} + 7[/tex]

⇒  [tex]\frac{2}{3}-7 = -\frac{x}{3}[/tex]   ( changing the side of 7)

⇒ [tex]-\frac{19}{3} = - \frac{x}{3}[/tex]

⇒ x = 19

So to get the output value 2/3 we will input x = 19

Use parallelogram ABCD What are the values of X and
y?​

Answers

Based on parallelogram ABCD shown below, the values of x and y include;

x = 17 units.

y = 10 units.

In Euclidean Geometry, a parallelogram is a type of quadrilateral and two-dimensional geometrical figure that has two equal and parallel opposite sides.

Generally speaking, a parallelogram has both pairs of opposite sides parallel to each other and the opposite angles (vertical angles) are congruent:

AB ║ CD

AB = CD

3x - 9 = 42

3x = 42 + 9

3x = 51

x = 51/3

x = 17 units.

Next, we would determine the value of y as follows;

4y - 3 = 37

4y = 37 + 3

4y = 40

y = 40/4

y = 10 units.

Complete Question:
