The surface area of the figures are;

Rectangle = 36.2 yd^2

Cuboid = 200 ft^2

Parallelogram = 27.8 cm^2

Cylinder = 138 yd^2

We can be able to obtain the surface area of various figures by the use of formulas.

For the rectangle, the surface area is = 7.1 yd * 5.1 yd = 36.2 yd^2

For the cuboid, the surface area = 2[(8 ft * 14 ft) + (4 ft * 8ft) + (14ft * 4 ft)] = 200 ft^2

For the parallelogram, the surface area = 5.4 cm * 5.14 cm = 27.8 cm^2

For the cylinder, the surface area is; (2 * 3.14 * 4^2) + (2 * 3.14 * 4 * 6) = 138 yd^2

The odds in favor of winning a prize in the contest of the juice company which gives prizes to anyone finding specially marked caps is 3.2.

In probability, the term odds against is the ratio of probability of non occurring a favorable event to the probability of occurring a favorable event. It can be given as,

[tex]\text{odd against}=\dfrac{P(\overline A)}{P(A)}[/tex]

Here, [tex]P(\overline A)[/tex] is the probability of not occurring a favorable event, and P(A) is the probability of occurring a favorable event.

A juice company gives the prizes to anyone finding specially marked caps on its juice bottles. The 4 bottles have winning cap in 20 bottles. Thus, the probability of winning is,

[tex]P(A)=\dfrac{4}{20}\\P(A)=\dfrac{1}{5}[/tex]

The probability of not winning is,

[tex]P(\overline A)=1-\dfrac{1}{5}\\P=\dfrac{4}{5}[/tex]

Thus, the odd against the winning is,

[tex]\text{odd against}=\dfrac{\dfrac{4}{5}}{\dfrac{1}{4}}\\\text{odd against}=\dfrac{16}{5}\\\text{odd against}=3.2[/tex]

Step-by-step explanation:

The independent variable is along the x-axis.

The dependent variable is along the y-axis.

Therefore,

Equation of the line

To find the equation of the line, define two points on the line:

Use the slope formula to find the slope (m) of the line:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{9-0}{5-0}=1.8[/tex]

From inspection of the graph, the y-intercept is at (0, 0).

Point-slope form of a linear equation:  [tex]y = mx + b[/tex]

Substitute the found slope and y-intercept into the formula to create the equation of the line:

[tex]\implies y=1.8x+0[/tex]

[tex]\implies y=1.8x[/tex]

Conclusion

y = 1.8x, where time is the independent variable, x, and distance is the dependent variable.

Solution

The measure of the diagonal of the rectangular garden will be 7.2 feet. Then the correct option is a.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the centre.

Landon has a rectangular garden with an area of 24.7 square feet. If the length of the garden is 5.7 feet.

Then the width of the garden will be

Area = Length x Width

24.7 = 5.7 x  W

 W = 4.33

Then the measure of the diagonal of the rectangular garden will be

D² = L² + W²

D² = 5.7² + 4.33²

D² = 32.49+ 18.74

D² = 51.23

D = 7.2

D ≅ 7.2 feet

Thus, the correct option is a.

B. They both have the same median.

C. They are both symmetric about the mean.

D. Data Set B is more spread out than Data Set A.

Step-by-step explanation:

a.

x = number of matching questions

y = number of essay questions

x >= 3

x <= 12

y >= 4

y <= 15

x + y <= 20

the delimiter lines are therefore

x = 3

x = 12

y = 4

y = 15

y = 20 - x

when you graph these lines, the corners (intersection points) of the inner shaded area are

(3, 4)

(12, 4)

(3, 15)

(12, 8)

(5, 15)

the other intersection points

(12, 15)

(3, 17)

(16, 4)

are outside the inner shaded area.

b.

10x + 25y = score

and this we want to maximize.

we have to try the 5 corners from a. and see, which one gives the maximum score.

(3, 4) gives

10×3 + 25×4 = 30 + 100 = 130

(12, 4) gives

10×12 + 25×4 = 120 + 100 = 240

(3, 15) gives

10×3 + 25×15 = 30 + 375 = 405

(12, 8) gives

10×12 + 25×8 = 120 + 200 = 320

(5, 15) gives

10×5 + 25×15 = 50 + 375 = 425

that is the most.

so, Phil should do 5 matching questions and 15 essay questions for maximum score.

Step-by-step explanation:

x² - 12x + 32 = 0

the goal is the vertex form : a form like

(x - h)² + k = r²

with (h, k) being the vertex or center and r the radius.

doing all the multiplications we get

x² - 2hx + h² + k - r² = 0

and we compare this with our original equation. we see

x² = x²

-12x = -2hx

-12 = -2h

6 = h

32 = h² + k - r²

32 = 36 + k - r²

-4 = k - r²

possible solution : k = 0 and then r = 2

but also e.h. k = 12, r = 4

so, without the information about e.h. the radius we cannot identify one solution.

so, "A" vertex form (one of many possible ones) is

(x - 6)² = 4

Answer:

b) f(x) = x² - 256

Step-by-step explanation:

Since we have been given the zeros of a function, -16 and 16. We are asked to find which function truly has those zeros.

To find this, we can substitute the zeros for x in the functions to find the one that is true/correct.

A) f(x) = x² - 16

 ⇒  0 = 16² - 16          and          ⇒  0 = (-16)² - 16

 ⇒  0 = 256 - 16        and          ⇒  0 = 256 - 16

 ⇒  0 = 240 ✘          and          ⇒  0 = 240 ✘

B) f(x) = x² - 256

 ⇒  0 = 16² - 256          and          ⇒  0 = (-16)² - 256

 ⇒  0 = 256 - 256        and          ⇒  0 = 256 - 256

 ⇒  0 = 0 ✔                  and          ⇒  0 = 0 ✔

C) f(x) = x² - 32x + 256

 ⇒  0 = 16² - 32(16) + 256         and        ⇒  0 = (-16)² - 32(-16) + 256

 ⇒  0 = 256 - 512 + 256           and        ⇒  0 = 256 + 512 + 256

 ⇒  0 = 512 - 512                       and        ⇒  0 = 512 + 512

 ⇒  0 = 0 ✔                               and        ⇒  0 = 1,024 ✘

D) f(x) = x² + 32x + 256

  ⇒  0 = 16² + 32(16) + 256         and        ⇒  0 = (-16)² + 32(-16) + 256

  ⇒  0 = 256 + 512 + 256           and         ⇒  0 = 256 - 512 + 256

  ⇒  0 = 512 + 512                       and         ⇒  0 = 512 - 512

  ⇒  0 = 1,024 ✘                          and        ⇒  0 = 0 ✔

Therefore, Function B has the zeros of x = -16 and x = 16.

Step-by-step explanation:

The value of √-4 and not -2 because

-2 * -2 = + 4.

Also there is no real number whose square is a negative.

Hi Student!

This question can seem quite complex but it has a simple explanation.  Just imagine, what is the purpose of a square root?  It shows what can by multiplied against itself and produce the number that is in the square root.  That is why when we take the square root of 4 we get 2 and -2 because they both produce the number 4 when we square them.  Whenever we square a number, no matter if it's positive or negative, the answer will always be positive.  This is because in order to get a negative number only one can be negative to overcome the positive otherwise it's just a double negative.

Therefore, there is a solution to the question of what is the square root of -4.  What we do is practically take out the negative because the square root of -1 is equal to i.  So we take the following steps

Separate the square root

Simplify the expression

Looking at what we have done, we see that although the explanation behind it might seem complex the actual solving portion isn't too hard when explained.  Therefore, the solution to the square root of -4 would be 2i.

The vertical asymptote is x = 1 and the horizontal asymptote is y = -1 if the equation of the hyperbola is f(x)=−3/x−1 −1

It's a two-dimensional geometry curve with two components that are both symmetric. In other words, the number of points in two-dimensional geometry that have a constant difference between them and two fixed points in the plane can be defined.

We have the equation of the hyperbola:

[tex]\rm f(x)=\dfrac{-3}{x-1} -1[/tex]

The asymptotes will be

Vertical asymptote:        x -1 = 0 ⇒ x = 1

Horizontal asymptote:   y + 1= 0 ⇒ y = -1

Thus, the vertical asymptote is x = 1 and the horizontal asymptote is y = -1 if the equation of the hyperbola is f(x)=−3/x−1 −1
