Answer:

y=x+8  and y=3x

Step-by-step explanation:

The Given point is (4,12)

now we can substitute the point in each of the function and check wether it lies on it or not.

A.  y=x+8

substitute y=12,x=4

12=4+8=12 which is true

B.  y=3x

substitute y=12,x=4

12=3*4=12 which is true

C.  y=2x

substitute y=12,x=4

12=2*4=8  which is not true

D.  y=x+6

substitute y=12,x=4

12=4+6=10 . which is not true

Therefore option A and B are correct.

Which composition of similarity transformations maps polygon ABCD to polygon A'B'C'D'?
Elina [12.6K]
Hey there!

Unless the smaller object was rotated 360° (in which case the rotation wouldn't have to be mentioned), you can see that all of the lines are still in the same place and that it wasn't rotated at all. This eliminated any answer option that mentions a rotation, which is A and C. 

Also, if you count the units of one of the straight lines – for example, line AB and A'B' – you can see that the smaller object is four times smaller than the larger object. In the case of line AB and A'B', line AB is 8 units long and A'B' is 2 units long. This means that the scale factor is \frac{1}{4}. 

Lastly, the smaller object was moved from its initial location, which would be in the center of the larger object if it wasn't moved after being scaled down. 

The answer will be B, "a dilation with a scale factor of \frac{1}{4} and then a translation."

Hope this helped you out! :-)

Following calculus questions. Thanks so much
Brrunno [24]

The vertical asymptote of the function that are illustrated in the calculus and the function y = 3cot(1/2x) - 4 will be:

B. x = 0

C. x = +-2π

<h3>How to illustrate the information?</h3>

It should be noted that the function that's given from the information illustrated is given as:

y = 3 for (x/2) - 4

It should be noted that there is no phase shift and the period is 2π.

It should be noted that the vertical asymptote will be x = 3πn where no is represented as the integer at n = 0, 1, and -1.

Therefore, the vertical asymptote of the function that are illustrated in the calculus and the function y = 3cot(1/2x) - 4 will be x = 0 and x = +2π.

Find the center of the circle that you can circumscribe about DABC.
Vlada [557]

The center of the circle that circumscribe about DABC is (h,k) = (1, 5).

A circle can be modelled after a expression of the form:

A\cdot x + B\cdot y + C =-x^{2}-y^{2} (1)

We can determine all coefficients by knowing three <em>distinct</em> points on plane.

If we know that (x_{1}, y_{1}) = (2, 8), (x_{2}, y_{2}) = (0, 8) and (x_{3}, y_{3}) = (2, 2), then the solution of the system of linear equations is:

2\cdot A + 8\cdot B + C = -68 (2)

8\cdot B + C = -64 (3)

2\cdot A + 2\cdot B + C = -8 (4)

A = -2, B = -10, C = 16

Now we proceed to <em>complete</em> squares and factor each resulting perfect square trinomial in order to determine the coordinates of the center of the circle:

x^{2}+y^{2}-2\cdot x -10\cdot y +16 = 0

(x^{2}-2\cdot x +1)-1+(y^{2}-10\cdot y +25)-25 +16 = 0

(x-1)^{2}+(y-5)^{2}= 10

The center of the circle that circumscribe about DABC is (h,k) = (1, 5).

If Z= 2+2i, what is z^4?
Dimas [21]

Answer:

assume z is equal to 5.

log(z^4/5) equals log(5^4/5) equals log(5^3) equals 2.096910013.

4 * log(5) - log(5) equals 2.096910013.

they give you the same answer.

this means they're equivalent.
