Answer:

C) 2744 cm

Step-by-step explanation:

To find the volume of a cube you have to use this equation:

V = a^3

Now plug in the number:

V = 14^3

14^3 or 14*14*14 = 2,744

The volume is 2,744 cm

Answer:

1) 2744cm^3

2)1176cm^2

Step-by-step explanation:

1)Since it's a square, the sides are all equal length. And volume=base×width×height

thus we can multiply 14×14×14=14^3=2744cm^3

2)for surface area we can find the area of on side and multiply it by 6 because the square has six equal sides. thus, area=base×height so, area=14×14=14^2=196cm^2

Now we multiply it by 6 which is equal to 1176cm^2

When the polynomial P(x) = 5x3 − 51x2 + kx − 9 is divided by x − 9, the remainder is 0. Which of the following is also a factor of P(x)?

A- x − 5
B- x + 1
C- x − 1
D- 5x + 1

Answers

Answer:

answer C:  (x - 1) is also a factor of P(x).

Step-by-step explanation:

Synthetic division is the best approach here.  Given that one factor is x - 9, we know that 9 is the appropriate divisor in synthetic division:

9    )    5    -51      k       -9

                 45    -54      (9k - 486)

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

           5     -6   (k - 54)  (-9 + 9k - 486)

and this remainder must = 0.  Find k:  -9 + 9k - 486 = 0, or

                                                                      9k = 486 + 9 = 495

                                                                      Then k = 495/9 = 55

Look at the last line of synthetic division, above:

5   -6   (k - 54)    0

Substituting 55 for k, we get:

5   -6     1          

These are the coefficients of the quotient obtained by

dividing P(x) by (x - 9).    They correspond to 5x^2 - 6x + 1.

We must factor this result.

Let's start with 5x + 1, and check whether this is a factor of 5x^2 - 6x + 1 or not.  If 5x + 1 is a factor, then the related root is -1/5.  Let's use -1/5 as the divisor in synthetic div.:

-1/5    )       5       -6        1

                           -1        7/5

         ----------------------------

                 5        -7       12/5       Here the remainder is not zero, so -1/5 is

                                                    not a root and 5x + 1 is not a factor.

Now try x - 5.  Is this a factor of 5x^2 - 6x + 1?  Use 5 as divisor in synth. div.:

5    )     5      -6      1

                    25    95

     ------------------------

         5         19     96  Same conclusion:  x - 5 is not a factor.

Try x = -1:

-1     )    5     -6     1

                    -5     11

        ----------------------

            5       -11     12.  The remainder is not zero, so (x + 1) is not a factor.

Finally, try x = 1:

1     )    5    -6     1

                  5    -1

      --------------------

          5     -1      0

Finally, we get a zero remainder, and thus we know that x - 1 is a factor of P(x)

Answer C is correct:  x - 1 is a factor of P(x)

To solve this question, we can apply the Remainder Theorem. According to the Remainder Theorem, if a polynomial \( P(x) \) is divided by \( x - c \), the remainder of the division is \( P(c) \).
Given:
\( P(x) = 5x^3 − 51x^2 + kx − 9 \)
We are told that when \( P(x) \) is divided by \( x − 9 \), the remainder is 0. Therefore, according to the Remainder Theorem:
\( P(9) = 5(9)^3 − 51(9)^2 + k(9) − 9 = 0 \)
Let's compute \( P(9) \):
\( P(9) = 5(729) − 51(81) + 9k − 9 \)
\( P(9) = 3645 − 4131 + 9k − 9 \)
\( P(9) = 9k − 495 = 0 \)
To solve for \( k \):
\( 9k = 495 \)
\( k = 495 / 9 \)
\( k = 55 \)
Now, we know that P(x) with \( k = 55 \) has no remainder when divided by \( x − 9 \).
The updated polynomial \( P(x) \) is:
\( P(x) = 5x^3 − 51x^2 + 55x − 9 \)
To determine which of the given options is a factor of \( P(x) \), we will test each option by plugging in the roots of these factors into the polynomial \( P(x) \) and checking if it yields zero.
A) For \( x − 5 \), the root is \( x = 5 \):
\( P(5) = 5(5)^3 − 51(5)^2 + 55(5) − 9 \)
\( P(5) = 5(125) − 51(25) + 275 − 9 \)
\( P(5) = 625 − 1275 + 275 − 9 \)
\( P(5) = 625 − 1009 \)
\( P(5) ≠ 0 \) (This factor does not yield zero, so it is not a factor of \( P(x) \).)
B) For \( x + 1 \), the root is \( x = -1 \):
\( P(-1) = 5(-1)^3 − 51(-1)^2 + 55(-1) − 9 \)
\( P(-1) = -5 − 51 − 55 − 9 \)
\( P(-1) = -120 \)
\( P(-1) ≠ 0 \) (This factor does not yield zero, so it is not a factor of \( P(x) \).)
C) For \( x − 1 \), the root is \( x = 1 \):
\( P(1) = 5(1)^3 − 51(1)^2 + 55(1) − 9 \)
\( P(1) = 5 − 51 + 55 − 9 \)
\( P(1) = 60 − 60 \)
\( P(1) = 0 \) (This factor yields zero, so it is a factor of \( P(x) \).)
D) For \( 5x + 1 \), the root is \( x = -1/5 \):
\( P(-1/5) = 5(-1/5)^3 − 51(-1/5)^2 + 55(-1/5) − 9 \)
\( P(-1/5) = -1/25 − 51/25 − 55/5 − 9 \)
Since the coefficients add up to a non-zero value, we can tell that it's not going to be zero; therefore, it is not worth computing the whole expression.
\( P(-1/5) ≠ 0 \) (Hence, this is also not a factor of \( P(x) \).)
The only option that gives a remainder of zero when its root is substituted into \( P(x) \) is C, \( x - 1 \). Therefore, the correct answer is:
C- x − 1

Answers

Answer:

12.5

Step-by-step explanation:

divide 25 by 2

Final answer:

To find the area of the painted part, subtract the area of the missing sector from the area of the entire circle.

Explanation:

The area of the painted part of the figure can be found by subtracting the area of the missing sector from the area of the entire circle. To find the area of the missing sector, we need to know the central angle of the sector. Once we have the central angle, we can use the formula for the area of a sector to calculate the area of the missing sector. Finally, we subtract the area of the missing sector from the area of the entire circle to find the area of the shaded part.



Example:



If the circle has a radius of 5 units and the central angle of the missing sector is 60 degrees, we can calculate:



Area of missing sector = (60/360) * π * 5^2

Question 3

Answer: slope is -1/10 or -0.1; slope tells us how much the candle height is decreasing each minute, y intercept is the starting candle height (see below for further explanation)

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

Explanation:

The y intercept is at 25, as this is where the diagonal line crosses the vertical y axis. Similarly, the x intercept is 250. The y and x intercept lead to the two points (0,25) and (250,0). Let's use the slope formula to find the slope of the line through these two points

m = (y2 - y1)/(x2 - x1)

m = (0 - 25)/(250 - 0)

m = -25/250

m = -1/10

m = -0.1

The slope of the line is -1/10 or the decimal equivalent -0.1

What does the slope tell us? It tells us how much of the candle's height is changing as each minute ticks by. Specifically, the slope -0.1 means that the candle height is going down by 0.1 cm for each minute gone by. A shorter way to say this is to say "the height is decreasing by 0.1 cm per minute" (think of it like a speed such as miles per hour)

The y intercept is the starting height of the candle due to the fact that x = 0 here. Therefore, the starting height of the candle is 25 cm.

Side note: the x intercept of 250 tells us how long the candle burns for, which in this case is 250 minutes (4 hrs, 10 min) because y = 0 for the x intercept, and y is the height of the candle at time x. Anything beyond x = 250 is not possible in realistic sense as we can't have a negative y height value.

Step-by-step explanation:

The first polygon, ABCD, should be rotated around DA' axis and then create a function f'(x)=f(x) +5 to transpose ABCD poligon into A'B'C'D' position

The second polygon, MNOP, rotate around MP axis and half the size ( Area)

Step-by-step explanation:

1b) First, reflect ABCDE over the x-axis.

(x, y) → (x, -y)

Then, translate 5 units to the right and 3 units down.

(x, -y) → (x+5, -y-3)

1c) Instead of reflecting over the x-axis, we can reflect ABCDE over the y-axis.

(x, y) → (-x, y)

Then, rotate about the origin 180 degrees.

(-x, y) → (x, -y)

Finally, translate 5 units to the right and 3 units down.

(x, -y) → (x+5, -y-3)

2b) First, rotate MNOP 90 degrees clockwise about the origin.

(x, y) → (y, -x)

Then, scale by 1/2.

(y, -x) → (y/2, -x/2)

Finally, translate 3.5 units to the left and 2.5 units down.

(y/2 - 3.5, -x/2 - 2.5)

2c) We can form a second method by changing the order of transformations.

First translate MNOP 5 units to the right and 7 units down.

(x, y) → (x + 5, y - 7)

Then scale by 1/2.

(x + 5, y - 7) → (x/2 + 2.5, y/2 - 3.5).

Finally, rotate 90 degrees about the origin.

(y/2 - 3.5, -x/2 - 2.5)

3b) First, rotate EFGH 45 degrees counterclockwise about the origin.

(x, y) → (½√2 (x - y), ½√2 (x + y))

Then scale by ⅓√2.

(½√2 (x - y), ½√2 (x + y)) → (⅓ (x - y), ⅓ (x + y))

Finally, translate 13/3 units to the right and 1 units down.

(⅓ (x - y), ⅓ (x + y)) → (⅓ (x - y) + 13/3, ⅓ (x + y) - 1)

3c) Again, we can form a second method by changing the order of the transformations.

Let's keep the first step the same, rotating EFGH 45 degrees counterclockwise about the origin:

(x, y) → (½√2 (x - y), ½√2 (x + y))

Then translate 13/√2 units to the right and 3/√2 units down.

(½√2 (x - y), ½√2 (x + y)) → (½√2 (x - y) + 13/√2, ½√2 (x + y) + 3/√2)

Finally, scale by ⅓√2.

(½√2 (x - y) + 13/√2, ½√2 (x + y) + 3/√2) → (⅓ (x - y) + 13/3, ⅓ (x + y) + 1)

4b) First, rotate XYZ 45 degrees clockwise about the origin.

(x, y) → (½√2 (x + y), ½√2 (y - x))

Then translate 5-√2 units to the right and 4√2 units up.

(½√2 (x + y), ½√2 (y - x)) → (½√2 (x + y) + 5 - √2, ½√2 (y - x) + 4√2)

4c) Instead, let's translate XYZ 5 units to the left and 3 units up.

(x, y) → (x - 5, y + 3)

Then rotate 45 degrees clockwise about the origin:

(x - 5, y + 3) → (½√2 (x + y - 2), ½√2 (y - x + 8))

Finally, translate 5 units to the right.

(½√2 (x + y - 2), ½√2 (y - x + 8)) → (½√2 (x + y - 2) + 5, ½√2 (y - x + 8))

This can be changed to the more common slope-intercept form.

Multiply: y + 3 = -6x - 54

Subtract: y = -6x -57

Answer:

y=-6x-57 (this answer is in slope-intercept form)

I don't know what your choices are and if you can select multiple answers or not.

Step-by-step explanation:

y=mx+b is an equation for a line with slope m and y-intercept b.

We are given m=-6 so we will plug this in giving us: y=-6x+b.

Now we need to find b, the y-intercept.  Let's use a point (x,y) we know is on the line of y=-6x+b to find b.

We know (x,y)=(-9,-3) is on that line.  So our line should satisfy this point.  We must pick a b so that happens.  Plug (x,y)=(-9,-3) into the equation now.

-3=-6(-9)+b

-3=54+b

-3-54=b

-57=b

So the equation is y=-6x-57

Marta was pregnant 268 days, 258 days, and 271 days for her first three pregnancies. in order for marta’s average pregnancy to equal the worldwide average of 266 days, for how long must her fourth pregnacy last? for Marta's average pregnancy to equal the worldwide average of 266 days, for how long must her fourth pregnancy last?

Answers

To find the average, you add all of the numbers and divide by the number of numbers (If that makes sense)

We can use variables (x) to solve for the last number.

268+258+271+x/4 = 266

Multiply both sides by 4

268+258+271+x = 266*4

268+258+271+x = 1064

Add the three numbers together

797+x = 1064

Subtract both sides by 797

x = 267

Her fourth pregnancy must last 267 days.

Answer:

267

Step-by-step explanation:

So we want to find the average of 4 numbers:

268, 258, 271, and x

The average of those 4 numbers is represented by the fraction:

[tex]\frac{268+258+271+x}{4}[/tex]

Now we also wanting this average to be equal to 266.  We need to find x such that that happens.

So we have the following equation to solve:

[tex]\frac{268+258+271+x}{4}=266[/tex]

Multiply both sides by 4:

[tex]268+258+271+x=4(266)[/tex]

Do any simplifying on both sides:

[tex]797+x=1064[/tex]

Subtract 797 on both sides:

[tex]x=1064-797[/tex]

Simplify:

[tex]x=267[/tex]

Answer:

Option B k > 0

Step-by-step explanation:

we know that

Observing the graph

The slope of the line is positive

The y-intercept is negative

we have

[tex]3y-2x=k(5x-4)+6\\ \\3y=5kx-4k+6+2x\\ \\3y=[5k+2]x+(6-4k)\\ \\y=\frac{1}{3}[5k+2]x+(2-\frac{4}{3}k)[/tex]

The slope of the line is equal to

[tex]m=\frac{1}{3}[5k+2][/tex]

Remember that the slope must be positive

so

[tex]5k+2> 0\\ \\k > -\frac{2}{5}[/tex]

The value of k is greater than -2/5

Analyze the y-intercept

[tex](2-\frac{4}{3}k) < 0\\ \\ 2 < \frac{4}{3}k\\ \\1.5 < k\\ \\k > 1.5[/tex]

1.5 is greater than zero

so

the solution for k is the interval ------> (1.5,∞)

therefore

City a and city b had two different temperatures on a particular day four times the temperature of city a was 8c more than 3 times the temperature of city b the temperature of city a minus twice the temperature of city b was -3c what was the temperature of city a and city b on that day

Answers

Answer:

temperature of city a=5

temperature of city b=4

Step-by-step explanation:

Given:

Let temperature of city A= a

temperature of city B=b

As given:

4a=8+3b

a-2b=-3

rearranging 2nd equation we get:

a=-3+2b

substituting above in 1st equation we get:

4(-3+2b)-3b=8

8b - 12 = 3b + 8

8b-3b=12+8

5b = 20

b = 4

Now substituting b=4 in 4a = 8 + 3b , we get

4a = 8 + 3b

4a = 8 + 3(4)

4a = 8 + 12

4a = 20

a = 20/4

a = 5

temperature of city a and city b on that day is 5C and 4C respectively!

Answer:

The temperature of the city a was 5 °C and b was 4 °C.

Step-by-step explanation:

First we have to write the equations based on the description, this is:

[tex]4a=8+3b\\a-2b=-3[/tex]

Now that we have the equations, we can replace the second in the first:

[tex]4(2b-3)=8+3b[/tex]

Now we can find the value of b:

[tex]8b-12=8+3b[/tex]

[tex]8b-3b=8+12[/tex]

[tex]5b=20[/tex]

[tex]b=\frac{20}{5}[/tex]

[tex]b=4\\[/tex]

Now with the value of b and the second equation we can get the value of a:

[tex]a-2(4)=-3[/tex]

[tex]a-8=-3[/tex]

[tex]a=8-3[/tex]

[tex]a=5[/tex]

The temperature of the city a was 5 °C and b was 4 °C.
