Use the Polygon tool to draw the image of the given quadrilateral under a dilation with a scale
Nataly [62]

Answer: See the picture attached.

Step-by-step explanation:

A Dilation is defined as  a transformation in which the image and the pre-image have the same shape, but their sizes are different.

When the scale factor is greater than 1, the image obtained after the  dilation is greater than the pre-image and it is an "Enlargement".

When the scale factor is is between 0 and 1,  the image obtained after the  dilation is smaller than the pre-image and it is an "Reduction".

In this case we know that the scale factor is:

scale\ factor=\frac{2}{3}

Since:

0

It is a Reduction.

You can identify that the vertices of the quadritaleral are:

(-3,0),(-9,-3),(-6,-9),(3,-6)

 So you need to multiply the coordinates of eac vertex by \frac{2}{3} in order to get the coordinates of the image.

Then, you get:

(\frac{(-3)(2)}{3},0*\frac{2}{3})=(-2,0)\\\\(\frac{(-9)(2)}{3}),\frac{(-3)(2)}{3})=(-6,-2)\\\\(\frac{(-6)(2)}{3},\frac{(-9)(2)}{3})=(-4,-6)\\\\(3*\frac{2}{3},\frac{(-6)(2)}{3})=(2,-4)

Now you can plot the points and draw the image of the given quadrilateral.

See the picture attached.

Find f'(x) (the derivative of f(x)) if f(x) = 7x'3 - 2x'2 + 4x - 5.
sdas [7]

Answer:

f(x)=7x'3-2x'2+4x-5

you have to subtract the the exponents by one and multiply by the coefficient

f(x)=21x'2-4x+4

I hope this helps

SOLVE. 3 sin x + 5 cos x = 0
Anestetic [448]
3 sin x + 5 cos x = 0
3 sin x = - 5 cos x  /: cos x ( divide both sides by cos x )
3 sin x / cos x = - 5
3 tan x = - 5
tan x = -5/3
x = arc tan (-5/3)
x ≈ - 59.036°

Which of the following angles is coterminal with one that measures 98 degrees
polet [3.4K]

Answer:

See below

Step-by-step explanation:

You have not provided the options.

But I will explain how you can work it.

Coterminal angles are two or more angles that have the same terminal side in standard.

If you want to find an angle that is coterminal with 98°, you keep adding or subtracting 360°.

98  + 360 = 458 \\ 98 + 2 \times 360 = 818

98 - 360 =  - 262

Therefore 488°, 818°, -262° are examples of angles that are coterminal with 98°
