Which of the following are the coordinates of vertices of the following square centered at the Origin, with side length b?

adoni [48]

Answer:

Option (3) is correct.

coordinate of given square centered at the Origin, with side length b is W $(\frac{b}{2},\frac{b}{2})$ , S $(\frac{-b}{2},\frac{b}{2})$ , T $(\frac{-b}{2},\frac{-b}{2})$ and Z $(\frac{b}{2},\frac{b}{2})$ .

Step-by-step explanation:

Given a square centered at the Origin, with side length b.

We have to find the coordinates of vertices of the square.

Since, the given square is centered at origin (0,0) and length of side is b then x and y axis divide each side in equal part.

Thus, each coordinate of square is $\frac{b}{2}$ .

Since, we know in first quadrant both x and y are positive thus, point W has coordinate $(\frac{b}{2},\frac{b}{2})$

Also in second quadrant x is negative and y is positive thus, point S has coordinate $(\frac{-b}{2},\frac{b}{2})$

in third quadrant both x and y is negative thus, point T has coordinate $(\frac{-b}{2},\frac{-b}{2})$

in fourth quadrant y is negative and x is positive thus, point Z has coordinate $(\frac{b}{2},\frac{b}{2})$

Thus, coordinate of given square centered at the Origin, with side length b is W $(\frac{b}{2},\frac{b}{2})$ , S $(\frac{-b}{2},\frac{b}{2})$ , T $(\frac{-b}{2},\frac{-b}{2})$ and Z $(\frac{b}{2},\frac{b}{2})$ .

Thus, option (3) is correct.

What is the value of x in the equation 4x+2=14×3x

MArishka [77]

4x+2= 14*3x
4x+2= 52x
Now subtract 4x from each side.
2= 48x
Divide each side by 48.
Final answer is 1/24.

"Use the chart above to determine the premium for 10 year term insurance. $12,000 policy for a 35-year-old female. Premium = ___

JulsSmile [24]

Option C) 63.48

The footnotes indicate that for female you have to use the rate for a male three years younger.

Then you have to use the rate for 32-year-old males, which is 5.29.

That rate is for evary $1,000 face value, the you have to calculate the premium in this way:

Premium = [5.29/1000]*$12.000 = 63.48
