Answer:
Picture 1: b
Picture 2: d
Picture 3: c
Step-by-step explanation:
Hi there,
For Picture 1, to solve for an inverse function, just simply solve for x. Since the closest you can get is arccos(πx)=2y+6, you just
solve for cosine as a function: cos(2y+6)=πx and solving for x:
x= (1/π)cos(2y+6) but since variable choice is arbitrary, you can now redefine y and x:
y= (1/π)cos(2x+6)
For Picture 2, tanx is equivalent to sinx/cosx and cscx is just the reciprocal of sinx. So, it becomes:
We have already been giving the cosine value of 2, and its inverse is thus 1/2.
For Picture 3, I would recommend revisiting polar coordinates.
Polar coordinates are in the form (r, θ).
and θ
. Recognize there are two possible radii, depending on what side of the circle you start from!
thanks,
Answer:
80
Step-by-step explanation:
First of all, before you do anything to compute the answer, you can see that there is (–13/100) on both sides of the equation. You can cancel them out, since they're the same thing.
Now, you're left with:
![0.8 = \frac{}{100}](https://tex.z-dn.net/?f=0.8%20%3D%20%5Cfrac%7B%7D%7B100%7D)
This is also read as 0.8 is the same thing as [how many] hundredths.
You should know that 0.8 = eight tenths.
So if you move the decimal point right once, you'll get:
0.80
Which is also eighty hundredths.
Your answer would be:
![0.8 = \frac{80}{100}](https://tex.z-dn.net/?f=0.8%20%3D%20%5Cfrac%7B80%7D%7B100%7D)
which is 80.
To check your answer, you can also do:
80/100
Because the fraction bar can also be read as "divided by."
You will get 0.8.
The largest angle measure is 110 degree
Answer:
LK = 7
Step-by-step explanation:
We are using segment addition
NM + ML + LK = NK
x-6 + 9 + 2x-19 = 23
Combine like terms
x+2x -6+9-19 = 23
3x -16 = 23
Add 16 to each side
3x-16+16 = 23+16
3x = 39
Divide each side by 3
3x/3 = 39/3
x = 13
We want to find the value of LK
LK = 2x-19
=2(13) -19
= 26 -19
= 7
Positive because it is above zero meaning more. if it has more than it could not be a negative because negatives are numbers to the left on a number line meaning less than zero.
