Answer:

y=4(1/2)^x

Step-by-step explanation:

Start with x=0, you know any number to the power of 0 is one. Since y=4, when x=0, you know the coefficient out front must be 4 b/c 4*1=4.

Next, look at x=1, which is equals 2. 1/2^1 = 1/2. Multiply by 4 to get 2. That means that b must equal 1/2. You can check this by looking at x=2. At x=2, y=1. (1/2)^2=1/4. 1/4(4)=1, making 1/2 the b value.

Nikki drew a rectangle with a perimeter of 18 units on a coordinate grid. Two of the vertices were (4, –3) and (–1, –3). What co

Answer:

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

Step-by-step explanation:

Geometrically speaking, the perimeter of a rectangle ( $p$ ) is:

$p = 2\cdot b + 2\cdot h$ (1)

Where:

$b$ - Base of the rectangle.

$h$ - Height of the rectangle.

Let suppose that the base of the rectangle is the line segment between (4, -3) and (-1, -3). The length of the base is calculated by Pythagorean Theorem:

$b = \sqrt{[(-1)-4]^{2}+[(-3)-(-3)]^{2}}$
