Answer:
4/3
Step-by-step explanation:
find common denomerator which is 12
so times 3/4 by 3
now its 9/12 + 7/12
get 16/12
Answer:
C is true also
Step-by-step explanation:
Answer:
Step-by-step explanation:
This is a proportion problem. I think you just lost a zero.
12/100 = 9/x Cross multiply
12x = 100*9 Combine the right.
12x = 900 Divide by 12
12x/12 = 900/12
x = 75 grams
So if you put 75 grams of tasty Oats in a bowl and covered it with milk the cereal would give you 9 grams of Protein.
2.
1 gram of Tasty Oats cereal contains 12/100 = 0.12 grams of protein.
1 gram of Cornbits contains 5/45 = 0.11 grams of protein.
By the narrowest of margins the Tasty Oats has more protein in it.
It would be .5x-5= because it says 5 less so it would be subtract 5 from half of x.
Answer:
Anything in the form x = pi+k*pi, for any integer k
These are not removable discontinuities.
============================================================
Explanation:
Recall that tan(x) = sin(x)/cos(x).
The discontinuities occur whenever cos(x) is equal to zero.
Solving cos(x) = 0 will yield the locations when we have discontinuities.
This all applies to tan(x), but we want to work with tan(x/2) instead.
Simply replace x with x/2 and solve for x like so
cos(x/2) = 0
x/2 = arccos(0)
x/2 = (pi/2) + 2pi*k or x/2 = (-pi/2) + 2pi*k
x = pi + 4pi*k or x = -pi + 4pi*k
Where k is any integer.
If we make a table of some example k values, then we'll find that we could get the following outputs:
- x = -3pi
- x = -pi
- x = pi
- x = 3pi
- x = 5pi
and so on. These are the odd multiples of pi.
So we can effectively condense those x equations into the single equation x = pi+k*pi
That equation is the same as x = (k+1)pi
The graph is below. It shows we have jump discontinuities. These are <u>not</u> removable discontinuities (since we're not removing a single point).
