Answer: T'(18,36)

Step-by-step explanation:

For this exercise it is important to know the definition of "Dilation".

 A Dilation is defined as a transformation in which the Image (The figure obtained after the transformation) and the Pre-Image (The original figure before the transformation) have the same shape but have different sizes.

If the Dilation is centered at the origin, and knowing the scale factor of \frac{9}{5}, you need to multiply each coordinate of the point T by the scale factor in order to find the coordinates of the Image T'.

Knowing that the point T has the following coordinates:

T(10,20)

You get that the coordinates of the Image T' are the shown below:

T'=(\frac{9}{5}*10,\frac{9}{5}*20)\\\\T'=(18,36)

PLEASE HELP WITH THESE TWO QUESTIONSSS 1. Which value is equivalent to sin20∘?
Nata [24]

Answer:

a) \cos(70\degree)

b) 12.72 units

Step-by-step explanation:

Recall that the sine and cosine are completed functions.

This means that:  \sin(x)=\cos(90-x)

\sin(20\degree)=\cos(90-20)

\sin(20\degree)=\cos(70\degree)

Recall that: sine ratio is opposite/hypotenuse

\sin 58=\frac{|PQ|}{15}

This implies that:

|PQ|=15\sin 58

|PQ|=15(0.848)

|PQ|=12.72

What is the greatest common factor (gcf) of the numerator and denominator in the rational expression below? 7x+14/2x^2+x-6
Mashutka [201]
The answer is C. The numerator 7x+14 can be factored as 7(x+2). The denominator 2x^2+2x-6 can be factored as (x+2)(2x-3). The greatest common divisor of 7(x+2) and (x+2)(2x-3) is obviously x+2, which is contained in both of the two expressions.
