Answer:

(g o f)(x) = \sqrt{-510} (not simplified)

Step-by-step explanation:

(g o f)(x) = g(f(x))

g(x) = \sqrt{3x}  f(x) = x^{3} + 9x

g(f(-5)) = g((-5)^{3} + 9(-5) = (-125) + (-45) = -170

g(-170) = \sqrt{3(-170)} = \sqrt{-510}

CAN SOMEONE PLEASE HELP ME WITH MY GEOMETRY HOMEWORK!!!! I DON'T UNDERSTAND WHAT I'M SUPPOSED TO DO SO CAN SOMEONE PLEASE HELP M
MAVERICK [17]

Answer:

  see attached

Step-by-step explanation:

Dilation is the transformation that changes the size of something. When you choose ×110% on a copy machine, you are making all the dimensions in the copy equal to 1.1 times the dimensions of the original, for example. That is dilation by a factor of 1.1, or 110%.

Here, you're asked to dilate triangle ABC by a factor of 3. That means all of the dimensions on the dilated figure will be 3 times their length on the original.

The center of dilation is point P. That means all the distances from point P are multiplied by 3.

In the attached figure, a gray arrow has been drawn from point P to each of the points A, B, and C. Then two more arrows of the same length are drawn in the same direction. The total distance at the end of the 3 arrows is 3 times the original distance from point P. These are the points A', B', and C' you are asked to draw. Connecting these points gives the dilated triangle A'B'C'.

___

You could think of point P (the center of dilation) as having coordinates (0, 0). Then points A, B, and C would have coordinates A(-4, 0), B(0, -3), and C(-4, -3). To dilate these points by a factor of 3, multiply each coordinate value by 3: A'(-12, 0), B'(0, -9), C'(-12, -9). You will see that these are the coordinates of the vertices of the dilated triangle.

Petra was given 12 yards of fabric to make costumes for the school play if each costume requires 1 1/2 yards how many costumes c
solmaris [256]

Petra can make 8 costumes with 12 yards of fabric

<h3><u>Solution:</u></h3>

Given that Petra was given 12 yards of fabric to make costumes for the school play

Each costume requires 1\frac{1}{2} yards

<em><u>To find: number of costume Petra can make</u></em>

The number of costume Petra can make is calculated by dividing the total fabric she has by fabric needed for one costume

\text {number of costume Petra can make }=\frac{\text {total fabric she has }}{\text {fabric needed for one costume }}

Total fabric she has = 12 yards

Fabric needed for 1 costume = 1\frac{1}{2} = \frac{2 \times 1 + 1}{2} = \frac{3}{2} yards

Therefore,

\text {number of costume Petra can make }=\frac{12}{3 / 2}=\frac{12}{3} \times 2=8

Thus petra can make 8 costumes with 12 yards of fabric
