Answer:

 = 1/3  * sqrt(1/2)

Step-by-step explanation:

sqrt(1/18)

We know that sqrt(a/b) = sqrt(a)/sqrt(b)

sqrt(1/18)

sqrt(1)/sqrt(18)

1/sqrt(18)

We also know that sqrt(ab) = sqrt(a) sqrt(b)

1/sqrt(18) = 1/ sqrt(9)sqrt(2)

              = 1/(3sqrt(2))

                 = 1/3 * 1/ sqrt(2)

We know that sqrt(a/b) = sqrt(a)/sqrt(b)

               = 1/3  * sqrt(1/2)

What is the measure of angle A?
I am Lyosha [343]

First you have to find the angle B (check attachment)

B = 180^{\circ} - 137^{\circ} = 43^{\circ}\\

Then you can find the last angle inside the triangle, which I'll call C

C = 180^{\circ} - 102^{\circ} - 43^{\circ} = 35^{\circ}

Now you can find angle A

A = 180^{\circ} - C = 180^{\circ} - 35^{\circ} = 145^{\circ}

For a set of five whole numbers, the mean is 4, the mode is 1, and the median is 5. What are the five numbers?
zmey [24]
SO we need 5 numbers that equal to 20, with 5 being the middle number, and ones being the most used number so

1 1 5 x y

According to this, x and y must equal 13 and both be bigger then 5. Because we can rule out every other number, x and y must be 6 and 7.

Your 5 numbers are 1, 1, 5, 6, 7.

Point C has the coordinates (–1, 4) and point D has the coordinates (2, 0). What is the distance between points C and D?
Bad White [126]

Answer:

5

Step-by-step explanation:

Use the distance formula d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

insert the numbers into the formula d=\sqrt{(2+1)^2+(0-4)^2}

2+1=3 and 0-4=-4

3^2 =9 and -4^{2} = 1

9+16=25

the square root of 25 is 5
