Find The Surface Area Of A Square Pyramid With Side Length 3 Km And Slant Height 3

Answers

Answer 1

Answer:

27 km²

Step-by-step explanation:

Surface Area :

Area (4 triangles) + Area (square)4 x 1/2 x 3 x 3 + 3 x 318 + 927 km²
Answer 2

Answer:

Total surface area = 27 km²

Step-by-step explanation:

The surface area of a square based pyramid comprises:

4 congruent triangles (sides)1 square (base)

Area of a triangle = 1/2 × base × height

                             = 1/2 × 3 × 3

                             = 4.5 km²

Area of a square = (side length)²

                            = 3²

                            = 9 km²

Total surface area = 4 triangles + square base

                              = (4 × 4.5) + 9

                              = 18 + 9

                              = 27 km²

hope it helps...!!!

Answer:

29 students

Step-by-step explanation:

Hello!

When expressed that the ratio of Teachers to Students is 2:29, the ratio is in the format Teachers: Students.

That means, for every 2 teachers, there are 29 students.

Ratio:

2(teachers): 29(students)

There are 29 students for 2 teachers.

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

What is a rectangle?

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.

what is the zero of this function?

Answers

Answer:

A. x = 5 and x = 6

Step-by-step explanation:

What are zeroes?

Zeroes are simply the x intercepts of a function or the coordinates where the function crosses the x axis

Finding the zeroes.

By looking at the graph, we can say that the function crosses the x axis at (5,0) and (6,0).

This means the x intercepts / zeroes are at x = 5 and x = 6 so the answer is A

What are the equations of the asymptotes for the function? f(x)=−3/x−1 −1

Answers

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

What is hyperbola?

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

can someone please help with this q^q

Answers

Answer:

[tex]y = -\frac{3}{4} sin(\frac{2}{3}x)[/tex]

Step-by-step explanation:

First determine whether it is a sine function or a cosine function. Since

sin(x) = 0 at x = 0 and we see indeed that the value of the function is 0 at x = 0 it must be a sine function

The general equation of a sine function is [tex]a sinbx[/tex]

where a is the amplitude. The amplitude is one-half the difference between the lowest and highest values in the graph.From the graph we can see that the highest value is 3/4 and lowest is -3/4 so the amplitude = 1/2 (3/4 + 3/4) = 3/4

If the amplitude were positive, the function would be increasing at (0,0) and going up to its amplitude value. However we can see that the function is decreasing at (0,0 ) and goes down to -3/4. Therefore the amplitude a has a negative sign so a = -3/4

To compute b, note that the period of the function ie where it finishes a full cycle is 3π since the function at that x value repeats itself. The relationship between b and the period is 2π/b = 3π in this particular case

This gives b = 2/3

So a = -3/4, b = 2/3 and the equation is [tex]y = -\frac{3}{4} sin(\frac{2}{3}x)[/tex]

Use a method to find the vertex form for x^2 - 12x + 32 = 0

Answers

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

PLEASE HELP! A juice company gives prizes to anyone finding specially marked caps on its juice bottles. You and your friends buy 20 bottles of juice. You find that 4 of the bottles have winning caps. What are the odds in favor of winning a prize in the contest?

Answers

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.

What is odds against?

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]

Thus, 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.

Which of these functions has zeros of x=−16 and x=16?
A
f(x)=x^2−16

B
f(x)=x^2−256

C
f(x)=x^2−32x+256

D
f(x)=x^2+32x+256

Answers

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.

Answer:

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

Step-by-step explanation:

The independent variable is along the x-axis.

The dependent variable is along the y-axis.

Therefore,

Independent variable = time (in minutes)Dependent variable = distance (in km)

Equation of the line

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

Let (x₁, y₁) = (0, 0)Let (x, y₂) = (5, 9)

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.
