Answer:

23.55

Step-by-step explanation:

We know it's three quarters of a circle since the angle is $270$ °

Therefore we can calculate like a normal circle and multiply by $\frac{3}{4}$ .

The formula for calculating the circumference is 2 times pi times the radius or $2\pi r$ .

$\pi=3.14\\2\times\pi=6.28\\6.28\times5=31.4\\31.4\times\frac{3}{4}=23.55$

Answer:

6 pints of white paint she used to paint her bedroom walls.

Step-by-step explanation:

Joy uses 9.5 pints of blue paint + white paint.

Joy used 3.5 pints of blue paint.

So, white paint used = total paint - blue paint used

Plug in the known values into the equation.

White paint used = 9.5-3.5 =6 pints

A segment in the complex plane has a midpoint at 3 – 2i. If one endpoint of the segment is at 7 i, what is the other endpoint? –

Brut [27]

The midpoint of a segment divides the segment into equal halves

The other endpoint is 1- 5i

<h3>How to determine the missing endpoint </h3>

The coordinates are given as:

Point 1: 7 + i

Midpoint: 3 - 2i

Represent the other endpoint with x.

So, we have:

2 * Midpoint = Point 1 + x

This gives

$2 * (3 - 2i) =7 + i + x$

$6 - 4i =7 + i + x$

Collect like terms

$x = 6 -7- 4i -i$

Evaluate the like terms

$x = 1- 5i$

Hence, the other endpoint is 1- 5i
