Answer:

Step-by-step explanation:

You really don't even have to calculate anything.

B can be reduced to 4/5 by dividing 24 by 6 and 30 by 6

C can be reduced to 1/15 by dividing 2 by 2 and 30 by 2

D can be reduced to 1/2.

The answer then is A

2 feet is 2 * 12 = 24 inches.

24/30 = 4/5. See B.

Answer:

W'' = (2, -3)

Step-by-step explanation:

Reflection over the x-axis negates the y-coordinate and leaves the x-coordinate alone. The W becomes ...

... W' = (-2, -3)

Reflection over the y-axis negates the x-coordinate and leaves the y-coordinate alone. The W' becomes ...

Answer:−3K−395,−374,−198,−187

Step-by-step explanation:

Remove parentheses.

1−3K−396,0−374,0−198,0−187

Simplify  1-3K-3961−3K−396  to  -3K-395−3K−395.

−3K−395,0−374,0−198,0−187

Simplify  0-3740−374  to  -374−374.

−3K−395,−374,0−198,0−187

Simplify  0-1980−198  to  -198−198.

−3K−395,−374,−198,0−187

Find the missing value when given the modulus. <br><br> |48+bi|=50
xxMikexx [17]

Answer:

missing value b is 14

Step-by-step explanation:

We have been given the modulus of a complex number which is

r=\sqrt{a^2+b^2}

Here on comparing the given complex number with general a+bi we get:

a=48 and b=b

On substituting the values in the formula for modulus we get:

\sqrt{48^2+b^2}=50

\Rightarrow 2304+b^2=50^2

\Rightarrow b^2=2500-2304

\Rightarrow b^2=196

\Rightarrow b=\sqrt{196}

\Rightarrow b=14

Therefore, missing value b is 14
