HELP AND JUSTIFY UR THINKINg!!
xenn [34]
This seems tricky, but if B can equal anything except 0, can B be anything on the x plane except 0. Meaning you can pick a number that you would justify. Let's say you picked x=2, it still fits the constraints and will connect with point A. (hoped this helped!)

A circle with area \blue{9\pi}9πstart color #6495ed, 9, pi, end color #6495ed has a sector with a central angle of \purple{60^\c
Liono4ka [1.6K]

Answer:

The area of the sector is 3pi/2

Step-by-step explanation:

A sector is that part of a circle bounded by 2 radii and an arc

The circle has an area of 9 pi with a central angle of 60 degrees.

Now the area of the sector is pretty much straight forward to calculate. Since it is a circle, the total angle we have is 360.

Now the sector subtends an angle of 60 degrees at the centre. What this means is that the sector is exactly 1/6 of the circle. meaning that cutting the circle into 6 slices will give the sector.

Thus, the area of the sector is one-sixth the area of the circle.

The area of the sector is thus 1/6 * 9pi = 9pi/6 = 3pi/2 or 3/2 pi

Select the equation of the line parallel to the equation y = -2x - 7  that passes through the point (3, 1).
cupoosta [38]
Parellel would mean that it's the same slope, so it's one of the first three. Checking each of them individually, we see that the first one, when you plug in 3, results in 1, getting (3,1)!

A number to the 12th power divided by the same number to the 9th power equals 216. What is the number?
Annette [7]

Answer:

The given such number is 6.

Step-by-step explanation:

Let the given such number  = m

Now, according to the question, the given expression is:

\frac{(m^{12}) }{(m^{9}) }   =  216

By the LAW OF EXPONENTS:

\frac{x^a}{x^b}  = x^{(a-b)}

⇒Here \frac{m^{12}}{m^9}  = m^{(12-9)}  = m^{(3)}

or, the given expression becomes m^3 =  216\\\implies m = \sqrt[3]{216}  = 6

or, m  = 6

Hence, the given such number is 6.
