Answer:

  y = 9(3^x)

Step-by-step explanation:

We assume you want a function in the form ...

  y = a(b^x)

that passes through points (0, 9) and (5, 2187).

Filling in the given point values, we have ...

  9 = a(b^0) = a

  2187 = a(b^5) = 9(b^5) . . . . using the above value of 'a'

Dividing the second equation by 9 and taking the 5th root, we find b.

  (2187/9) = b^5

  243^(1/5) = b = 3

The exponential function is ...

  y = 9(3^x)

Answer:

Not all lines have an x- and y-intercept. This line does not cross the x-axis. Similarly, the line x=2 is a vertical line which does not cross the y-axis.

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

I am assuming you are talking about linear functions. When it comes to them, most of them have a y-intercept, and if they do, they are counted as functions. Linear functions must have some sort of slope, but because there is a special line that does not have a slope, then it is not a function. And since it does not have a slope, it also does not hit the y-axis. Usually, the equation is set to equal y, for example:

y = 1

But, a line that does not have a slope is equal to x, like:

x = 1

x = 1 is a completely vertical line that is parallel to the y-axis, which means it does not have a y-intercept.

To experiment this, you can try it in Desmos, which is a secure graphing website. I hope this helps you!

Answer:

446.75 y^2

Step-by-step explanation:

First, Kelly found the area of a circle, not half a circle, which is on top of the figure. She also shouldn't have subtracted the area of the circle by the airea of the base, as she is trying to find the area of the ENTIRE figure.

.5 TIMES pi times 9^2 = 122.75

the second part, calculating the square base is correct..

122.75+324 = 446.75 y^2

Answer:

x=16°

Step-by-step explanation:

tanθ=opposite/adjacent

tan(<CAB)=BC/AB

<CAB=tan⁻¹(21/29)=35.9097308°

tanθ=opposite/adjacent

tan(<DAB)=BD/AB

<DAB=tan⁻¹((21/2)/29)=19.90374954°

<CAB=<DAB+x

x=<CAB-<DAB

=35.9097308-19.90374954

x=16.00598126°

The area of the triangle is of 8 units of area.

Step-by-step explanation:

Answer:

The area of the triangle is of 21 units of area.

Step-by-step explanation:

The area of a triangle with three vertices [tex](x_1,y_1),(x_2,y_2),(x_3,y_3)[/tex] is given by the determinant of the following matrix:

[tex]A = \pm 0.5 \left|\begin{array}{ccc}x_1&y_1&1\\x_2&y_2&1\\1_3&y_3&1\end{array}\right|[/tex]

In this question:

Vertices (1,0) (5,0) (3,4). So

[tex]A = \pm 0.5 \left|\begin{array}{ccc}1&0&1\\5&0&1\\3&4&1\end{array}\right|[/tex]

[tex]A = \pm 0.5(1*0*1+0*1*3+1*5*4-1*0*3-0*5*1-1*1*4)[/tex]

[tex]A = \pm 0.5*(20-4)[/tex]

[tex]A = \pm 0.5*16 = 8[/tex]

The area of the triangle is of 8 units of area.

Answer:

Number of curry buns is 16.

Step-by-step explanation:

Total number of buns =40.

Ratio of number of raisin buns to the number of butter buns to the number of curry buns = 7:5:8

Let number of raisin buns = 7X.

Let number of butter buns =5X.

Let number of curry buns = 8X.

Therefore,

7X+5X+8X = 40

20X = 40

X= (40/20) = 2.

Therefore number of curry buns =8X = 8×2 =16.

Answer:

[tex]x =2[/tex]

[tex]y =2[/tex]

Step-by-step explanation:

Given

[tex]9x^2 + 4(y - 2)^2 = 36[/tex]

[tex]x^2 = 2y[/tex]

Required

Solve

Substitute:  [tex]x^2 = 2y[/tex] in [tex]9x^2 + 4(y - 2)^2 = 36[/tex]

[tex]9*2y + 4(y-2)^2 = 36[/tex]

[tex]18y + 4(y-2)^2 = 36[/tex]

Open bracket

[tex]18y + 4[y^2-2y - 2y + 4] = 36[/tex]

[tex]18y + 4[y^2-4y + 4] = 36[/tex]

Open bracket

[tex]18y + 4y^2-16y + 16 = 36[/tex]

Collect like terms

[tex]4y^2+18y-16y + 16 - 36 = 0[/tex]

[tex]4y^2+2y-20= 0[/tex]

Divide through by 2

[tex]2y^2+y-10= 0[/tex]

Expand

[tex]2y^2+5y - 4y-10= 0[/tex]

Factorize

[tex]y(2y + 5) - 2(2y + 5) = 0[/tex]

Factor out 2y + 5

[tex](y -2)(2y + 5) = 0[/tex]

Split

[tex]y - 2 =0\ or\ 2y + 5 = 0[/tex]

Solve for y

[tex]y =2 \ or\y = -\frac{5}{2}[/tex]

We have:

[tex]x^2 = 2y[/tex]

Make x the subject

[tex]x = \sqrt{2y[/tex]

The above is true for positive y values.

So: [tex]y =2[/tex]

This gives

[tex]x = \sqrt{2*2[/tex]

[tex]x = \sqrt{4[/tex]

[tex]x =2[/tex]

A 3-D figure is a shape that its three surfaces can be observed at the same time.  Therefore, required answer to the given question is: A. Two regular octagons and eight congruent rectangles.

When the length, width and height of a given shape can be observed at the same time, then its is said to be in a 3-D. However, polygons are shapes which has 3 or mores sides. Examples are: trigon, hexagon, octagon etc.

Thus, since the 3-D figure required in the question has two bases in the shape of regular octagon, which should have 8 sides connected by congruent polygons of length greater than their width.

This implies that the sides of the figure must be made up of eight congruent rectangles, because the 3-D figure has eight regular sides (which would be the width of the rectangles). Then, the height of the figure would be the length of the rectangles.

So, the correct option to the given question is A. Two regular octagons and eight congruent rectangles.

The mean number of points scored by given players is 8. The correct answer would be an option (B).

The arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.

The formula for the mean of a given set of data is as follows:

Mean = Sum of Observations/Total number of observations

Σx = 4 + 6 + 10 + 9 + 11

Σx = 40

Here n = 5

⇒ Mean = Σx/n

⇒ Mean = 40/5

⇒ Mean = 8

Thus, the mean number of points scored by given players is 8.
