Alright so the parentheses mean (x, y) so basically you have to plug in the numbers in parentheses into the equation so here's what I got:

a. i
b. iv
c. ii
d. v

So then e must be iii, let’s check:
y = -x + 1
.5 = -.5 + 1 ✔️
.75 = -.25 + 1 ✔️
.875 = -.125 + 1 ✔️

So that’s how you would solve those equations. Hope this helps.

Answer:

y- intercept = \frac{1}{2}

Step-by-step explanation:

Given

f(x) = \frac{1}{2} (6)^{x}

To find the y- intercept let x = 0 , then

f(0) = \frac{1}{2} (6)^{0} [ 6^{0} = 1 ]

      = \frac{1}{2} × 1 = \frac{1}{2} ← y- intercept

A circular target is divided into four rings that have equal areas. If the radius of the target is 24cm, find the radius of the
MAVERICK [17]

THE AREA OF THE RING WHICH IS INSIDE CIRCULAR TARGET IS 12CM.

Step-by-step explanation:

A circular target which is divided into four rings of equal areas as given in the information

The area of the circular target is

Area = \pi * R².

As per the given data radius of the target 'R' is 24cm,

Area of circular target = \pi * 24²

=>  576 \pi.

let us consider radius of ring equals to 'r',

So, each of the ring has area of

=> Area of ring = (\pi * 576) / 4

=> 144 * \pi

Now let us consider area of the small ring inside circular target

Area of ring = \pi * r²

\pi * r² = 144  \pi

Taking off the \pi from both sides

r² = 144

r = 12.

Therefore radius of ring which is inside circular target is 12 cm.
