A circle has an arc whose measure is 80° and whose length is 88π, What is the diameter of the circle?

Answer:

P(2)=0 then x-2 is a factor of P(x)

Step-by-step explanation:

To see if (x-2) is a factor just plug in 2 for x into the polynomial expression.

2(2)^3-3(2)^2-17(2)+30

2(8)-3(4)-34+30

16-12-34+30

4-34+30

-30+30

0

Since P(2)=0 then x-2 is a factor

Answer:

multiply 2/5 by 4

Step-by-step explanation:

When we divide fractions, we use copy dot flip

2/5 ÷ 1/4

Copy dot flip

2/5 * 4/1

For this case we must find the quotient of the following expression:

[tex]\frac {\frac {2} {5}} {\frac {1} {4}} =[/tex]

Applying double C we have:

[tex]\frac {2 * 4} {5 * 1} = \frac {8} {5}[/tex]

This is equivalent to multiplying the following: [tex]\frac {2} {5} * 4 = \frac {8} {5}[/tex]

option C.

The statement that best describes a square is: A special rectangle that has four sides of equal length. This statement aligns with the definition of a square within the field of geometry, where a square is understood as a type of rectangle with all sides being the same length. Therefore, the correct answer is C. A special rectangle that has four sides of equal length.

A square indeed has four right angles, similar to a rectangle. By extension, it has congruent opposite sides and equal angles, but the defining feature that differentiates a square from other rectangles is the fact that all four sides are of equal length. The concept of rectangles forming squares can be seen in the given reference, implying that equal rectangles can be arranged to form a square - a concept important in understanding how a square is a special case of a rectangle.

Answer:

x = 1

Step-by-step explanation:

ln x + ln x = 0

2ln x = 0

ln x = 0

recall ln x = [tex]log_{e}[/tex]x

so equation becomes

[tex]log_{e}[/tex]x = 0

or [tex]e^{0}[/tex]=x

since anything raised to the power of zero = 1

x = 1

Answer:

x = 1

Step-by-step explanation:

We are to find the solution of the following logarithmic equation:

[tex] ln ( x ) + l n ( x ) = 0 [/tex]

We will add the similar elements to get:

[tex] 2 l n ( x ) = 0 [/tex]

Dividing both sides by 2 and simplify to get:

[tex] \frac { 2 l n ( x ) } { 2 } = \frac { 0 } { 2 } [/tex]

[tex]ln(x)=0[/tex]

Applying the rule [tex]a=log_b(b^a)[/tex] to get:

[tex]0=ln(e^0)=ln(1)[/tex]

[tex]ln(x)=ln(1)[/tex]

Here the logs have the same base, so:

x = 1

Answer:

(x - 8)^2 + (y - 4)^2 = 16.

Step-by-step explanation:

The standard form can be written as:

(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the center and r = the radius.

So here we have a = 8, b = 4 and r = 4.

(x - 8)^2 + (y - 4)^2 = 4^2

(x - 8)^2 + (y - 4)^2 = 16.

The base of the exponential expression 4^5 is 4.

The base of an exponential expression refers to the number being raised to a power.

In the exponential expression 4 to the power of 5, the base is 4 because it is the number being multiplied by itself 5 times.

Therefore, the base of the exponential expression 45 is 4.

Answer:

∛16

Step-by-step explanation:

First, remember that the denominator always goes outside the radical and the numerator inside. so with that, it looks like this.

∛2^4

simplify.

∛16

To solve this question, we must use the cosine rule:

cos(A) = (b^2 + c^2 - a^2)/2bc, where A is the angle you want to find, a is the side opposite that angle, and b and c are the other two sides of the triangle.

Given that we know that a = 6, b = 12, c = 14, we can substitute these values into the formula to get:

cos(A) = (12^2 + 14^2 - 6^2)/2(12)(14)

cos(A) = (144 + 196 - 36)/336

cos(A) = 304/336

cos(A) = 19/21

A = cos-1(19/21)

A = 25° (to the nearest degree)

Answer: third option.

Step-by-step explanation:

You know that the height of the smaller cylinder is 1 cm and the height of the  larger cylinder is 3 cm, then you can find the volume ratio. This  is:

[tex]Volume\ ratio=(\frac{1\ cm}{3\ cm})^3\\\\Volume\ ratio=\frac{1}{27}[/tex]

Knowing that the volume of the larger cylinder is 2,106 cubic centimeters, you need to multiply it by the volume ratio to find the volume of the smaller cylinder.

Therefore:

[tex]V_{smaller}=\frac{1}{27}(2,106\ cm^3)\\\\V_{smaller}=78\ cm^3[/tex]

ANSWER

The correct answer is C

EXPLANATION

We have that, the smaller cylinder has height 1 cm and the larger cylinder has height 3cm.

The scale factor of similarity is

[tex]k = \frac{1}{3} [/tex]

That's if the smaller cylinder is the image.

The volume of the larger cylinder is 2106 cm³.

To find the volume of the smaller cylinder, we multiply the volume of the larger cylinder by k³

[tex]( { \frac{1}{3} })^{3} \times 2106 {cm}^{3} [/tex]

[tex]{ \frac{1}{27} } \times 2106 = 78 {cm}^{3} [/tex]

Answer:

22.34 km²

Step-by-step explanation:

Here we have a circle whose diameter is 5  1/3 km.  As an improper fraction, that's 16/3 km.  Half that, or 8/3 km, is the radius.

The area of a circle is A = πr², where r is the radius.

In this case, the area is A = π(8/3 km)², or (64/9)π km², or 22.34 km² (same as first answer choice).

To find the product of two expressions, we use the distributive property and multiply each term from the first expression with each term from the second expression, then combine the like terms.

The product of[tex](3a + 2)(4a^2 - 2a + 9) is 12a^3 - 6a^2 + 23a + 18.[/tex]

To find the product of two binomials, you can use the distributive property. In this case, you multiply each term in the first binomial, 3a and 2, by each term in the second binomial, 4a^2, -2a, and 9, and then combine like terms.

[tex](3a + 2)(4a^2 - 2a + 9) = 3a * 4a^2 + 3a * (-2a) + 3a * 9 + 2 * 4a^2 + 2 * (-2a) + 2 * 9[/tex]

Now, perform the multiplications:

[tex]12a^3 - 6a^2 + 27a + 8a^2 - 4a + 18[/tex]

Combine like terms:

[tex](12a^3 - 6a^2) + (27a - 4a) + 1812a^3 - 6a^2 + 23a + 18[/tex]

So, the product of[tex](3a + 2)(4a^2 - 2a + 9)[/tex]is indeed[tex]12a^3 - 6a^2 + 23a + 18.[/tex]

Answer: $22.50

Step-by-step explanation: let x represent the amount Laura and Lilly contributed each. If Laura and Lilly contributed the same amount, x+x=2x=45. If 2x=45, divide both sides by 2 to find the value of x. 45/2= 22.5.

Laura contributed $15 toward the purchase of the video game.

The question is asking to determine the amount contributed by Laura to buy a video game for their brother, Liam, if the entire cost of the game is $45 and Laura contributed half as much as Lilly. For simplicity, let's assume Lilly contributed x dollars. Then Laura, contributing half as much, would have contributed x/2 dollars. Given that their total contribution is $45, we set up the equation x + x/2 = 45. Solving for x, we find that Lilly contributed $30 and Laura, half of this, contributed $15.

Step-by-step explanation:

we know that

The scale factor of the dilation is 0.25 ----> given problem

The coordinates of point A(-5,-3) and F(3,1)

step 1

Find the x-coordinate of point A'

The horizontal distance between A and F is equal to

AFx=3-(-5)=8

The horizontal distance after dilation between A'F is equal to

A'F=0.25*8=2

so

the x-coordinate of vertex A' is equal to the x-coordinate of F minus the horizontal distance after dilation A'F

A'x=3-2=1

step 2

Find the y-coordinate of point A'

The vertical distance between A and F is equal to

AFy=1-(-3)=4

The vertical distance after dilation between A'F is equal to

A'Fy=0.25*4=1

so

the y-coordinate of vertex A' is equal to the y-coordinate of F minus the vertical distance after dilation A'F

A'y=1-1=0

therefore

The coordinates of vertex A of the image is (1.0)

Answer:

Rebecca has 18 nickels and 27 dimes

Step-by-step explanation:

Let x be the number of nickels Rebecca has, then 45-x is the number of dimes she has.

The total value of Rebecca's coins is $3.60.

1 nickel - 5 cents

x nickels - 5x cents

1 dime - 10 cents

45-x dimes - 10(45-x) cents

Total x nickels and 45-x dimes is 5x+10(45-x) cents that is $3.60=360 cents. So,

5x+10(45-x)=360

5x+450-10x=360

5x-10x=360-450

-5x=-90

5x=90

x=18

45-x=45-18=27
