All you have to do is plug the x coordinate into the funtion.

If you plug in the first points then you will end up getting 128. So you know that point is not there.

Doing the for the rest:

2) 128 (0.5)^1 = 64

3) 128 (0.5)^3 = 16

4) 128 (0.5)^8 = 0.5

The points (2,4) and (-2,-4) are plotted on a coordinate plane the equation is y = a * x what is A?
laila [671]

A equals to 2.

<u>Step-by-step explanation:</u>

y = mx + c is the equation of the line and m is the slope and c is the y- intercept.

In the given equation, y = ax , a is the slope.

Slope A can be found by means of the formula, and using the points (2,4) and (-2-4)

slope, A = (y₂ -y₁) /  (x₂-x₁)

Plugin the values as,

A = (-4-4) / (-2-2) =  (-8) / (-4) = 2

So the value of A is 2.

I need help locating , x=,y=,z= please. Thanks
Kamila [148]
For x, (52tan)/1=x/35=44.79 which simplifies to 44.80
For y, (52sin)/1=44.80/x=56.852 which simplifies to 56.85
For z, sin^-1=(35/56.85)=37.9995 which simplifies to 38.00.
