Which transformations were used to create a triangle JKL

Answers

The second one because the triangle prime is much smaller than the green one. And the reflection is towards the x axis

The transformation used to create K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.

What is transformation?

"Transformations are change in the original shapes on a coordinate plane by rotation, reflection or translation. "

What is reflection transformation?

"It is a transformation which produces mirror image of geometrical structure."

What is dilation?

"It is a transformation in which size of the geometrical structure is changed without changing its shape."

From given diagram,

we can observe that JK = 4 and J'K' = 2

This means the size of the triangle J'K'L' is reduced by 1/2

Also, it is reflected along x-axis.

This means, the transformation used to create triangle K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.

Therefore, the correct answer is option (B).

Step-by-step explanation:

Speed= Distance/Time

All you have to do is divide the time by distance

like this:  23 ÷ 11

The answer would be 2.090909090909091, but since you are rounding the answer would be A. 2.09

Simplify negative 3 over 4 divided by 2 over negative 8.

Answers

Answer:

3

Step-by-step explanation:

−3/4÷2/−8=?

In the second fraction, move the negative sign from the denominator to the numerator and the value remains the same.

The equivalent equation is

−3/4÷ −2/8=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator, leaving the negative sign on the numerator, and changing the operation to multiplication. Then the equation becomes

−3/4× −8/2=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

−3× −8/4×2= 24/8

Since 24 divided by 8 equals 3 then,

24/8 =3

Therefore:

−3/4÷ 2/−8= 3

The table below shows the height and the hand span of five students.


Which pattern of association best describes the relationship between the height and the hand span?





A. no association

B. nonlinear association

C. positive linear association

D. negative linear association

Answers

Positive linear association because increase in two inches higher increase hand span by .5 inches

There is no association between the height and the hand span.

We can only establish an association when there is a consistent rate of increase or decrease between two variables. The increase or decrease is linear when they occur smoothly.

As we can see, we can not establish any particular relationship between the height and the hand span hence we conclude that there is no association between them.

To find the y-coordinate of a point when the x-coordinate is 2, all you have to do is look for the x-intercept of 2 and look for the y-intercept.

When you look at the bottom of the graph, you can see that the x-coordinate 2 and the y-coordinate -5 intersect to form a point.
