Answer:
A. (5,9)
Step-by-step explanation:
First, you need to reflect across the line of reflection. Since the point is 7 units from the line y=2 from one side, it will be 7 units away when it is reflected. 2+7=9, so the reflected coordinates of the point are (-2,9). For the glide translation, you slide the point 7 units to the right, placing it at the final location of (5,9). Hope this helps!
Answer:
f(x) = cos(x)
Step-by-step explanation:
tanx cscx = (sinx/cosx) * (1/sinx) = 1/cosx
1/f(x) = 1/cosx
f(x) = cos(x)
Answer:
b(n) = -23 + 18n
Step-by-step explanation:
NOTE - This is an arithmetic sequence, so each number is increasing by addition. If you were in a geometric sequence, however, you'd be multiplying. This means that the explicit formula for the geometric sequence you'll be learning later on will be different.
The formula for explicit formula is b(n)=b(1)+d(n-1). The variable d represents the common difference and the a is whatever number of the term you are using.
Since you have b(1), you look at what your first term is. Plug -5 into a(1).
To find your common difference, find 13-(-5). This is 18, and adding it to the others you can see that it continues.
So, plugging in what you have so far it looks like b(n) = -5 + 18(n - 1)
All we need to do now is simplify.
1. Distribute: -5 + 18n - 18
2. Add like terms: -23 + 18n
Hope this helped and made sense lol.
Sounds like a good deal to go swimming!
N=90 you have to simplify both sides then isolate the variable :)
