1/4= 0.25

Answer:

C

Step-by-step explanation:

Constant of proportionality is basically a ratio, or a unit rate.

For example, if there was the ratio 1:3, the COP (constant of proportionality) would be 3. If one pencil costs 50c, then the COP is .50 or 1/2.

In this problem, y is the single unit, and the COP is 0.25. That means that we need to find a unit rate that is multiplying by 0.25, or 1/4. This is found in option C.

Answer:

$6000

Step-by-step explanation:

so basically, 25% of the 100% value is gone, right? which means that 75% of the value would remain. After that, all is easy. 8000*0.75, since 75% is 0.75, and the answer of that is 6000, so the current value is 6000 dollars.

2sec^2x - secx - 1 = 0
Ivenika [448]
What are you trying to do here?
Solve the graph, or make it appear as something else?

First, we're going to take one sec (x) out so that we get:
sec (x) (2sec (x) -1 -1) = 0

sec (x) (2sec (x) -2) = 0


Then we're going to separate the two to find the zeros of each because anything time 0 is zero.

sec(x) = 0

2sec (x) - 2 = 0

Now, let's simplify the second one as the first one is already.

Add 2 to both sides:

2sec (x) = 2

Divide by 3 on both sides:

sec (x) = 1


I forgot my unit circle, so you'd have to do that by yourself. Hopefully, I helped a bit though!
