146. They are asking for the angle XY, the blue line.

For instance, imagine it is 90 deg, instead of 73, it would cut the circle in two, and XY would be 180 deg. Imagine it would be 45 degrees, it would leave a quadrant, and that's 90 deg.

So the angle * 2 (they are different angles)

I think 'TheBestBrain' thought they were asking for the supplementary angle, but I think it is the arc length angle (blue line)

Write an exponential function that includes the following given pair of points.

alina1380 [7]

Answer:

$f(x)=-2^x$

Step-by-step explanation:

So generally an exponential equation is expressed in the form: $f(x)=a(b)^x$ and: $b=1+r\text{ or }b=1-r \text{ depending on whether it's decaying or growing}$ . In this case we see that as x increased by 1, the y-decreases, BUT the absolute value is increasing, so it's really just reflected.

Plug in known values:

$-2=a(b)^1$

$-4=a(b)^2$

So if you think about it. you really have

-2 = a * b

-4 = a * b * b

since ab = -2, then we can substitute this into the second equation

-4 = -2 * b

-4 = -2b

Divide both sides by -2

b = 2

You can also deduce that b=2, by realizing to go from -2 to -4, you have to subtract 100% of -2 from -2. This means r=1, so b=1+1, b=2

Anyways, now it's time to solve for a, by plugging in a point as well as b.

-4 = a(2)^2

-4 = 4a

-1 = a

You can verify this by using the other point

-2 = -(2)^1

-2 = -(2)

-2 = -2

So the equation is: $f(x)=-2^x$

You pay $38.50 for a sweater that is marked 30% off the regular price. what is the regular price of the sweater? how much did yo

SpyIntel [72]

The regular price is $55.00 and saved $16.50.

You have to work backwards. To get the sale price you normally have to multiply the original price by the percent (%30 -> .30) then subtract to find the price of an item on sale.

But, in this case that was done for us, so instead we have to work backwards.
To do that you have to do $38.50/.70 = $55 (the original price).
