What is the greatest common factor of 4x^3
and 8x^2?

Answers

Answer:

the gcf is 4

Step-by-step explanation:

Final answer:

To find the greatest common factor of 4x³ and 8x², we look at the numerical coefficients and the variables separately. The GCF of the coefficients 4 and 8 is 4, and since x² is the lowest power of x common in both terms, the GCF is 4x².

Explanation:

The greatest common factor (GCF) of two expressions, like 4x³ and 8x², involves finding the highest degree of common terms they share. First, let's compare the numerical coefficients; 4 and 8. The GCF of 4 and 8 is 4. Next, we'll look at the variable part. The lowest exponent of x that appears in both terms is 2. Therefore, the GCF is the product of the GCF of the coefficients and the lowest power of x, which is 4x².

When working with rational expressions, restricted values are values of your variable that results in an undefined rational expression. Given the following rational expressions: 2x+4/x^2−x−6 and 2/x−3 Determine whether the rational expressions are equivalent and explain your answer. Determine the values that would make the rational expressions undefined. Are these values the same or different? Explain.

Answers

Answer:

See below

Step-by-step explanation:

2x+4 / x^2-x-6

= 2(x+2)/(x-3)(x+2)

= 2/(x-3)

So the 2 expressions are equivalent

The values of x which make the expressions undefined are those values which make the denominators 0

For 2x+4/ x^2-x-6 they are X=3 and x= -2.

For 2/x-3 they are x =3.

Question 1
Factor the following expression using the GCF. Type your factored expression below.
4xy + 12w + 12Z

Answers

Answer:

4(xy + w + z)

Step-by-step explanation:

The expression to be factored is:

          4xy + 12w + 12z

Factoring an equation involves taking out common terms from the expression that will then make it more simpler and simplified.

To solve this problem, we need to find the factors of the given terms:

            4xy

            12w

            12z

The numbers given as coefficients of the variables are;

                       4            12               12

A factor is any integer that divides a number evenly;

             Factors of 4 are 1, 2 and 4

                              12 are 1, 2,3,4,6 and 12

The common factors between 4 and 12 are those numbers that can divide both digits:

      These are  1, 2, and 4, they are common to both

Now, the greatest common factor is the highest of this factors which is 4

 Therefore, the greatest common factor of 12 and 4 is 4

Also, xy, w and z has no common factors

Factoring

                 4xy + 12w + 12z  = 4(xy + w + z)

10. George, Sandy, Carlos, and Michelle all ate a piece of a whole
pecan pie. George ate 0.15 of the pie, Michelle ate of the pie,
and Carlos ate of the pie. Sandy ate more than two of her
friends, but less than the other one. What is a possible
percentage of the ple Sandy ate?​

Answers

Answer:

0.150 < (Proportion of Sandy's pie) < 0.167

15% < (Percentage of Sandy's pie) < 16.7%

Step-by-step explanation:

Total percentage of pie = 100% or 1

George, Sandy, Carlos, and Michelle all ate a piece of the pie.

George ate a fraction of 0.150

Michelle ate a fraction of (1/6) = 0.167

Carlos ate a fraction of (1/7) = 0.143

The amount of pie left = 1 - 0.15 - (1/6) - (1/7) = 0.5405

And Sandy is known to eat more than two of her friends, but less than one of them.

Of the amount of pie eaten by the first 3 friends, (1/6) is the highest proportion.

Hence, it is evident that Sandy ate more than 0.143 and 0.150 (Carlos and George) but less than Michelle (0.167).

So, mathematically, the possible proportion of cake that Sandy ate is

0.150 < (Proportion of Sandy's pie) < 0.167

How many $5 raffle tickets were sold?

Which equation can be used to determine how many $1.50 raffle tickets were sold?

How many $1.50 raffle tickets were sold?

Answers

Answer:

see below

Step-by-step explanation:

1.5x + 5y = 1152    

x = 4y – 2

We can substitute the second equation into the first equation

Which one-variable linear equation can be formed using the substitution method?

1.5(4y-2) +5y = 1152  

Distribute

6y -3 +5y = 1152

Combine like terms

11y-3 = 1152

Add 3 to each side

11y-3+3 = 1152+3

11y = 1155

Divide each side by 11

11y/11 = 1155/11

y = 105

How many $5 raffle tickets were sold?

105 5 dollar tickets were sold

Now we need to find the number of 1.50 tickets

Which equation can be used to determine how many $1.50 raffle tickets were sold?

x = 4y – 2

x = 4(105) -2

   =420-2

   = 418

How many $1.50 raffle tickets were sold?

418    $1.50 tickets were sold

Answer:

11y = 1155

$5 raffle tickets: 105

x = 4(105) - 2

$1.5 raffle tickets: 418

Step-by-step explanation:

1.5x + 5y = 1152    

x = 4y – 2

1.5(4y - 2) + 5y = 1152

6y - 3 + 5y = 1152

11y = 1155

y = 105

x = 4(105) - 2

x = 418

find the value of c so that (x+2) is a factor of the polynomial p(x). p(x)=4x^3+cx^2+x+2

Answers

Answer:

c = 8

Step-by-step explanation:

Use synthetic division here; it's the fastest approach.

Given that (x + 2) is a factor, take -2 and use this as the divisor in synthetic division:

-2     4         c                1           2

                  -8    (-2c+ 16)      (4c-34)

       ---------------------------------------------

         4    (c - 8)   (-2c + 17)     4c - 32

The remainder, 4c - 32, must equal zero if (x + 2) is a factor.

Then 4c - 32 = 0, and c = 8

A circular plate has circumference 23.9 inches. What is the area of this plate?

Answers

Answer:

Rounded to the nearest thousandth: ≈45.479

Step-by-step explanation:

The formula for finding area using circumference is

[tex]\frac{c^2}{4\pi }[/tex]

c=23.9"

[tex]\frac{23.9^2}{4\pi }[/tex]

Since we're using 3.14 for pi, multiply 4 by 3.14, and continue from there.

[tex]\frac{23.9^2}{4(3.14)} = \frac{571.21}{12.56} = 45.47850318[/tex]

but we don't use that big number! We round to the nearest thousandth!

≈45.479

Answer:

46 inches^{2}

Step-by-step explanation:

The formula for the area of a circle is [tex]\pi r^{2}[/tex]

To work this out you would first need to divide 23.9 by pi to find out diameter.

Then you would divide the diameter by 2 to find the radius. Then you would multiply pi by the radius squared.

1) Divide 23.9 by [tex]\pi[/tex].

[tex]23.9/\pi=7.608[/tex]

2) Divide 7.608 by 2.

[tex]7.608/2=3.804[/tex]

3) Multiply pi by the radius squared.

[tex]\pi *3.804^{2} =45.4601526[/tex]

4) Round To nearest whole number.

B is the answer correct

Point P partitions the directed line segment from A to B into the ratio 3:4. Will P be closer to A or B? Why

Answers

Final answer:

Point P will be closer to B than to A because the ratio of the partition is 4/7 which is closer to B than the ratio of 3/7 to A.

Explanation:

To determine whether point P will be closer to A or B, we need to consider the ratio of the partition. In this case, the ratio is 3:4. This means that the segment from A to P is 3/7 of the total segment, and the segment from P to B is 4/7 of the total segment.

Since the ratio of the partition is closer to B (4/7) than to A (3/7), point P will be closer to B than to A.

For example, if the distance from A to B is 7 units, the distance from A to P will be 3 units (3/7 * 7) and the distance from P to B will be 4 units (4/7 * 7).

If point P partitions the directed line segment from A to B into the ratio 3:4, then P will be closer to A. The ratio 3:4 means that the segment AP is 3 parts long while segment PB is 4 parts long, making PB longer than AP. The entire segment AB is therefore divided into 7 equal parts, with point P falling 3/7 of the distance from A and 4/7 from B. Since 3/7 is less than 4/7, P is closer to A.

In the diagram below, point U is on segment $\overline{BY}$ and the measure of angle BUG is 30 degrees greater than the measure of angle GUY:

Answers

Answer: 75

Step-by-step explanation:

We have angle BUG angle GUY = angle BUY = 180. If we let angle GUY = x, then

(x+30) + x = 180 Solving this equation gives x=75.

Using the definition of linear pair angles, the measure of angle GUY is: 75°.

What is a Linear Pair?

A linear pair are two angles on a straight line whose sum equals 180 degrees.

Thus:

m∠BUG = m∠GUY + 30°

Therefore:

m∠BUG + m∠GUY = 180°

Substitute

m∠GUY + 30 + m∠GUY = 180 (linear pair)

2(m∠GUY) + 30 = 180

2(m∠GUY) = 180 - 30

2(m∠GUY) = 150

m∠GUY = 150/2

m∠GUY = 75°

Therefore, using the definition of linear pair angles, the measure of angle GUY is: 75°.

What is an area circle?

The area of the circle is given by the pie times square of the radius.

Area of circle = πr^2


Standard form of the equation of circle = ( x - h ) ²+ ( x - y )² = r²
Where r is the circle's radius and h and k is the circle's center.
Given equation of the circle =  (x + 2)² + (y - 3)² = 25
where center is ( -2, 3 )
radius r = √25 = 5

While plotting a circle on a graph marks the center at ( -2, 3 ) radius. and draw the circle of radius 5 around the center ( -2, 3 ). The result is shown in the image.

Thus, the required graph that represents circle (x + 2)² + (y - 3)² = 25. is given below in the image.
