Rotate the following point (- 5, 7) with a 90 degree CCW rotation
Sergio039 [100]

Given:

The point is (-5,7).

To find:

The image of the given point after 90 degrees counter clockwise rotation.

Solution:

If a point rotated 90 degrees counter clockwise, then

(x,y)\to (-y,x)

Let the given point is P(-5,7). Using the above rule, we get

P(-5,7)\to P'(-7,-5)

Therefore, the image of the given point after 90 degrees counter clockwise rotation is (-7,-5).

I need help on all this

#2:

Find the total surface area of the capped cylinder.

2 times the area of the base would be 2[pi*(3 cm)^2, or 18pi.

The circumference of the base is C = 2pi*r, which here is 6pi.
The area of the sides is C times height, or 6pi*(11 cm) = 66pi cm^2

Add this to the 18pi cm^2 previously found.

Total area of cylinder, including top and bottom, is 84 cm^2.

What is the LCD of 1/6 and 3/10
Marta_Voda [28]
The LCD is 30.

Think of it this way.  You and I are on an assembly line checking i-pads.  Your job is to quality check every 6th one and my job is to check every 10th one.
Here are the ones you will check:

6, 12, 18, 24, 30 and so on
Here are the ones I will check
10, 20 30 and so on.

Notice the first one we both check?  #30 - that is the LCD of 6 and 10

Which value is equivalent to: 1 1/2 divided by 4 1/2 x 1 1/3
Nostrana [21]

Answer:

The answer is 4/9

Step-by-step explanation:

Hi. Here's the work.

First turn everything into an improper fraction.

1 \frac{1}{2} ÷ 4 \frac{1}{2} * 1 \frac{1}{3} = \frac{3}{2} ÷ \frac{9}{2} * \frac{4}{3}

To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.

\frac{3}{2} ÷ \frac{9}{2} * \frac{4}{3} = \frac{3}{2} *\frac{2}{9} *\frac{4}{3}

Now we just multiply the fractions!

\frac{3 * 2 * 4}{2 * 9 * 3} = \frac{4}{9}

The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)
