Answer:  B. 0, 2

Step-by-step explanation:

x² - 2x = 0

x(x - 2) = 0                          Factored the left side

x = 0   and    x - 2 = 0         Applied the Zero Product Property

                     x = 2              Solved the remaining equation

Therefore, x = 0 and x = 2

The measure of angle XYA is 26 degrees if the YX is a tangent to circle O at point X.

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have:

YX is a tangent to circle O at point X.

Arc XB = 52 dergees

Arc XA = 104 degrees

By the theorem of secant:

m∠XYA  =  1/2(m∠arc XA - m∠arc XB)

= 1/2(104 - 52)

= 26 degrees

Thus, the measure of angle XYA is 26 degrees if the YX is a tangent to circle O at point X.

y = 3x - 5

Graph C touches (0,-5) and no other graphs do.

1/2 of 1/3 of 1/4 of 80ft

= 1/2 of 1/3 of (1/4 of 80ft)

= 1/2 of 1/3 of 20ft

= 1/2 of (1/3 of 20ft)

= 1/2 of (20/3) ft

= 20/6 ft

> 18/6 ft

So the order was longer than 3 feet.

Answer:

[tex]y=40,500(1.038^{x})[/tex]

Step-by-step explanation:

Let

x----> the time in years

y----> the population

we know that

[tex]100\%+3.8\%=103.8\%=103.8/100=1.038[/tex]

so

[tex]y=40,500(1.038^{x})[/tex]

Final answer:

For Krystal City's population of 40,500 increasing at 3.8% annually, the function is [tex]P(t) = 40500(1 + 0.038)^{t[/tex].

Explanation:

A population function can be represented as:

[tex]P(t) = P_0(1 + r)^{t[/tex]

Where:

For Krystal City with a population of 40,500 and a growth rate of 3.8% annually, the function would be:

[tex]P(t) = 40500(1 + 0.038)^{t[/tex]

Answer:

36π cm³

Step-by-step explanation:

The volume (V) of a sphere is calculated using the formula

V = [tex]\frac{4}{3}[/tex]πr³ ← r is the radius = 3

V = [tex]\frac{4}{3}[/tex]π × 3³

  = [tex]\frac{4}{3}[/tex]π × 27

  = 4π × 9 ( cancelling the 3 and 27 )

  = 36π cm³

Here is your answer

B) [tex]36×pi[/tex] [tex]{cm}^{3}[/tex]

REASON:

We know that,

Volume of sphere= [tex] 4/3 pi×{r}^{3} [/tex]

Here r= 3cm

So, V= [tex] 4/3 × pi× {3}^{3} cm^3 [/tex]

= [tex] 4×pi × {3}^{2} cm^3 [/tex]

= [tex] 4×9× pi cm^3 [/tex]

6. decrease / 19.68 ,5. increase / 4.4

Step-by-step explanation:

Slope intercept form:

y=mx+b

Right now we have:

-y=4-x

x=1 because it’s not being multiplied by anything

y-intercept = 4 because it’s what you’re adding

Then we just need to move 4 to the other side of “x”

And with that, we conclude with a line in slope intercept form:

-y=x-4

It’s a negative 4 and a positive x, because you’re supposed to do the opposite

If it’s a negative, you add. If it’s a positive, you subtract.

Answer:

The radius is 4.5 ft

Step-by-step explanation:

The volume of a sphere is

V = 4/3 pi r^3

121.5 pi = 4/3 pi r^3

Divide each side by pi

121.5 = 4/3 r^3

Multiply each side by 3/4

121.5 *3/4 = r^3

91.125 = r^3

Take the cube root on each side

(91.125) ^(1/3)= (r^3)^(1/3)

4.5 = r

The radius is 4.5 ft

Answer:

He spent 35 minutes swimming each day.

Step-by-step explanation:

10x5=50

The multiply by 5 is the numbers of days.

225-50=175

(The 50 minutes subtracted is the time Devon walked)

175 divided by 5 = 35

He spent 35 minutes swimming

Confirm/Check    

35 times 5 =175

( Again, The multiply by 5 is the 5 days.)

175+50= 225

Therefore, He swam 35 minutes each day and walked 10 minutes each day.

He swam 175 minutes in total and walked 50 minutes in total

Hoped This Helped!

The number of minutes Devon swam each day is

The word problems must be thoroughly read and understood. Then we can use the given data to make the equations.

He exercised for a total of 225 minutes in the last week.

It is also given that he exercised the amount each day for 5 days.

Therefore, the total number of minutes of exercise per day = 225/5

= 45 minutes.

It is given that he spends 10 minutes everyday walking.

Therefore the total number of time Devon spend swimming = 45 - 10

= 35 minutes

Therefore, we have found that the number of minutes Devon swam each day is 35 minutes.

Answer and Explanation :

To find : What is the phase shift of a periodic function?

Solution :

The Phase shift is defined as a horizontal shift in a function in any direction.

Horizontal stretches will change the period of the function and that horizontal shift is called a phase shift or the amount of shift in a wave horizontally.

The phase shift is measured in degrees.

Refer the attached figure below for the pictorial representation of teh phase shift.

In the figure, [tex]\frac{\pi }{2} \text{ to } \pi[/tex] is showing the phase shift.

Example - Taking a general example of sin function

[tex]y = A \sin(B(x + C)) + D[/tex]

In this the phase shift is at C (positive is to the left).

Answer:

Discriminant = 88

Step-by-step explanation:

The general form of quadratic polynomial is:

P(x) = ax² + bx + c ⇒ a is the coefficient of x² , b is the coefficient

of x and c is the numerical term

∵ The discriminant of P(x) = ax² + bx + c is b² - 4ac

∵ P(x) = 2x² + 4x - 9

∴ a = 2 , b = 4 , c = -9

∴ Discriminant = (4)² - 4(2)(-9) = 16 + 72 = 88

Answer:

The discriminant of given polynomial is 88.

Step-by-step explanation:

We have given a polynomial.

2x²+4x-9

We have to find the discriminant of given polynomial.

From polynomial, a  = 2 , b = 4 and c = -9

The formula to find discriminant is

b²-4ac

Putting values in above formula, we have

(4)²-4(2)(-9)

16+72

88

The discriminant of given polynomial is 88.

For 1 year Jeff pays $1200.

For 6 years he pays 7200 / 6 = 1200 per year.

For 9 years he pays 10800 / 9 = 1200 per year.

Jeff's unit rate is $1,200 per year.

Daniel pays $1,150 per year.

150 is less than 1200, so the answer would be:

-6p - 2 is the answer.

Hope this helped!!!!

~Shane

Final answer:

The expression 0.5(-12p - 4) simplifies to -6p - 2 by distributing the 0.5 across each term inside the parentheses, resulting in the multiplication of -12p by 0.5 to get -6p, and -4 by 0.5 to get -2.

Explanation:

The expression 0.5(-12p - 4) can be simplified by distributing the 0.5 across the terms inside the parentheses. This is done by multiplying 0.5 by each term in the parentheses individually. The steps are as follows:

Multiply 0.5 by -12p, which gives us -6p.

Multiply 0.5 by -4, which gives us -2.

Combine these results to get the simplified expression, which is -6p - 2.

Therefore, 0.5(-12p - 4) equals -6p - 2.

Tina will need 64 cardboard building blocks to build the wall.

Step 1: Convert all measurements to inches.

The thickness of the wall is already 4 inches.

The height of the wall is 3 feet. Since 1 foot = 12 inches, then:

[tex]3 \text{ feet} = 3 \times 12 \text{ inches} = 36 \text{ inches}[/tex]

The length of the wall is 12 feet. Therefore:

[tex]12 \text{ feet} = 12 \times 12 \text{ inches} = 144 \text{ inches}[/tex]

Step 2: The volume of a rectangular wall can be found using the

formula:

[tex]\text{Volume} = \text{Length} \times \text{Height} \times \text{Thickness}[/tex]

Substituting the values:

[tex]\text{Volume} = 144 \text{ inches} \times 36 \text{ inches} \times 4 \text{ inches}[/tex]

[tex]\text{Volume} = 20736 \text{ cubic inches}[/tex]

Step 3: The dimensions of the block are 9 inches x 9 inches x 4 inches,

so:

[tex]\text{Volume}_{\text{block}} = 9 \text{ inches} \times 9 \text{ inches} \times 4 \text{ inches}[/tex]

[tex]\text{Volume}_{\text{block}} = 324 \text{ cubic inches}[/tex]

Step 4: To find out how many blocks are needed for the wall, divide the

total volume of the wall by the volume of one block:

[tex]\text{Number of blocks} = \frac{\text{Volume of wall}}{\text{Volume of one block}}[/tex]

[tex]\text{Number of blocks} = \frac{20736 \text{ cubic inches}}{324 \text{ cubic inches}}[/tex]

[tex]\text{Number of blocks} = 64[/tex]

A rigid transformation is a transformation that preserves the shape and size of an object. It includes translations, rotations, and reflections. In order for triangle ΔABC to be mapped to triangle ΔDEC, there must be a combination of translations, rotations, and reflections that can bring the two triangles into congruence.

However, without specific information about the coordinates or measurements of the vertices of the triangles, it is not possible to accurately determine if a rigid transformation exists that can map ΔABC to ΔDEC.

The correct answer is 36.
