Here , we are given with a circle on cartesian plane , and we need to find the equation of the circle , We are also given that it's centre is at (5,-6) { From graph } and it's radius is 3 units . Now , as we know, the standard equation of a circle is [tex]{\bf (x-h)^{2}+(y-k)^{2}=r^{2}}[/tex] where (h,k) is the centre of the circle and radius is r . Now , our equation will be ;

[tex]{:\implies \quad \sf (x-5)^{2}+\{y-(-6)\}^{2}=3^{2}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{(x-5)^{2}+(y+6)^{2}=9}}}[/tex]

This is the required equation of Circle

Or if you want to proceed it further , then you will get x² + y² - 10x + 12y + 50 = 0

The best approximation for the area of the circle which has the 6 cm long radius is 113 ft². Option 4 is correct.  

The area of the circle is the space occupied by that circle in 2 dimensional plane or space. It can be given as,

[tex]A=\pi r^2[/tex]

Here, (r) is the radius of the circle.

The image of the circle is attached below. In the given figure the center of the circle is O and the radius of the circle is 6 cm.

Thus the area of this circle can be find out using the above formula as,

[tex]A=\pi (6)^2\\A=3.14\times6^2\\A=113.04\\A\approx113\rm ft^2[/tex]

Thus, the best approximation for the area of the circle which has the 6 cm long radius is 113 ft². Option 4 is correct.

Answer:

  (a)  (3x +1)(x +1)

Step-by-step explanation:

The values of the factors are represented by the horizontal and vertical dimensions of the area. In each direction, we have a "blue" dimension, and a "red" dimension.

Horizontally, we have a dimension of (3 × blue + 1 × red).

Vertically, we have a dimension of (1 × blue + 1 × red).

We can assign blue = 1, red = x, and we would have (3 +x)(1 +x). This does not match any answer choices.

We can also assign blue = x, red = 1, and we would have (3x +1)(x +1). This matches the first answer choice.

The product which is represented by the algebra tiles is (a)  (3x +1)(x +1)

This refers to the branch of mathematics where letters and symbols are used to represent numbers.

Hence, we can see that from the given image, there are different values which shows the horizontal and vertical dimensions of the area and from the:

Hence, if we represent the values of blue = 1, red = 1, then it would produce (3x +1)(x +1) and this is the correct answer.

Answer:

The poster is 11 inches wide and 19 inches in height.

Step-by-step explanation:

We take the given equation: (x^2+2x-15) and we add in 14 as our x variable:

((14)^2+2(14)-15) the answer we get from that is 209. The area of the poster is 209 square inches. Then we find the width by taking (x-3) in this case x is 14 so the width of the poster is 11. In order to find the height we divide the height by the width and we get 19.

Therefore:

Height= 19 Inches

Width= 11 Inches

Total Area= 209 Square Inches

1. K(x) = (3x)2 -x + 2 -x + 1

k(x) = g(x) ∘ h(x)

2. K(x) = 2 ^3x + 2

k(x) = g(x) × h(x)

3. K(x) = 2^x - 3x - 2

k(x) = h(x) ÷ g(x))

4. K(x) = 3(2 x) + 2

k(x) = h(x) ∘ g(x)

5. K(x) = 2^x + 3x + 2

k(x) = g(x) - h(x)

6. K(x) = 2^x(3x + 2)

k(x) = g(x) + h(x)

Answer:

x = 7

Step-by-step explanation:

The dashes on the lines show they are equal in length.

Therefore, by inspection of the diagram, we can see that the measures of the sides of the smaller triangle (with base 5x) are half the measures of the sides of the larger triangle (with base 70).

Therefore, creating an equation with this information:

    5x = 1/2 x 70

⇒ 5x = 35

⇒ x = 7

Solution:

Note that:

This means that...

Simplify the equation and solve for x.

The value of x is 7.

1. 8/5 = $1.60

2. 11/8 = $1.375 = $1.38

3. 23/20 = $1.15

Answer:

Step-by-step explanation:

We can do this  a couple of ways. We can graph it -- see below. Or we can do the math.

Math

y = x^2 - 2x - 15

This trinomial factors into

y = (x - 5)(x + 3)

from which

x - 5= 0

x = 5

and

x + 3 = 0

x = - 3

The y intercept is the value obtained when all the xs on the right = 0

y = 0^2 - 2*0 - 15

y = - 15

Answer

The graph is below.

Answer:

There are infinitely many solutions.

Step-by-step explanation:

So there are three possible scenarios. The is a finite set of solutions, there are infinitely many solutions, or there are no solutions.

We can determine which of these scenarios is possible by analyzing the pair of equations.

Y = (1/4)x - 1

Y = (1/4)(x - 4)

For clarity, I have put parentheses around the fractional component 1/4.

Note, the first equation can be rewritten as such:

Y = (1/4)x - 1

Y = (x/4) - 1

And the second equation can be simplified using the distributive property of multiplication

Y = (1/4)(x - 4)

Y = (1/4)x - (1/4)(4)

Y = (x/4) - (1)

Y = (x/4) - 1

Notice, both equation are actually the same. This means whatever values of x or Y you put in, the two equations will always be equal. This means there are infinitely many solutions because there are an infinite combination of x and Y that solve pair of equations given, which is actually the same equation. In the graph, this is represented as a line on top of the existing line.

The way that the correlation will be affected if the units are changed from minutes to seconds is that the correlation will still be the same.

Correlation simply means a statistical measure which expresses the extent to which two variables are linearly related.

From the information, it was stated that twenty-five trials are completed and the correlation coefficient between typing speed and time is determined to be -0.622.

In this case, even when the units for time are changed from minutes to seconds, the correlation won't change. This is because the change in units has no effect on the correlation.
