Answer:

B. g(x)=5f(x)

Step-by-step explanation:

The graph of function g is a vertical stretch of the graph of function f by a factor of 5. Let analyse all the possible answers:

For C and D are the same transformation and they are only be transformed horizontally and be compressed over the x-axis.

When 0 < |a| < 1 (when a is between 0 and 1), the function is compressed vertically by a dilation factor of |a|.

When |a| > 1 (when a is greater than 1), the function is stretched vertically by a dilation factor of |a|.

Lastly, when a is negative, the function is reflected in the x-axis and then it is stretched or compressed vertically by a dilation factor of |a|.

For A, the parameter 0 < a =1/5 < 1, so it will make the original function compress vertically over the y-axis
For B, the parameter a= 5> 0, so it will make the original function stretch vertically over the y-axis

Hence, we choose B

Answer:

Step-by-step explanation:

For answer A it is stretching the graph of function f by a factor of 15.

For answer C and D it is changing the function itself and that is not what the question is asking.

Consider the statement : Congruent triangles are always similar. Which of the following statements is an example of the statemen

swat32

Answer:

Yes, the congruent triangles are always similar. The following statements are applicable

1) Angles are the same, but sides are proportional to eachother.

2) Sides are the same size.

3)Corresponding angles and corresponding sides are congruent.

Step-by-step explanation:

Yes, they are similar.

For two triangles to be similar, it is sufficient if two angles of one triangle are equal to two angles of the other triangle. Note that if two angles of one are equal to two angles of the other triangle, the third angles of the two triangles too will be equal.

If two triangles are congruent then all corresponding sides as well as corresponding angles of one triangle are equal to those of other triangles. This can happen in four cases

1)- when all sides of triangles are equal,

2) - if one side and two angles of one are equal to one side and two angles of other triangle.

3) - if two sides and included angle of one triangle are equal to two sides and included angle of other triangle

4)- if in two right angled triangles, one side and hypotenuse of one triangle are equal to one side and hypotenuse of other triangle.

Observe that for triangles to be similar, we just need all angles to be equal. But for triangles to be congruent, angles as well as sides should be equal.

Hence, while congruent triangles are similar, similar triangles may not be congruent ( but the converse is not true) .

The wavelength of red light in a spectrum is about 0.0000007 meters. Which

Nana76 [90]

Answer:

$0.0000007$

And if we count the number of zeros before the number 7, we can rewrite the number like this:

$7x10^{-7}$

We cansolve this problem also counting the number of positions that we need to move the decimal point to the right in order to obtain the first number (7)

And the best option would be:

B. 7 x 10-7

Step-by-step explanation:

For this case we have the following number given:

$0.0000007$

And if we count the number of zeros before the number 7, we can rewrite the number like this:

$7x10^{-7}$

We cansolve this problem also counting the number of positions that we need to move the decimal point to the right in order to obtain the first number (7)

And the best option would be:

B. 7 x 10-7
