Please help me. I am having some trouble with these problems
s344n2d4d5 [400]

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.

9/17 15/34 6/17 9/34 geometric sequence?
zysi [14]
In a geometric sequence each number after the first is found by multiplying the previous number by a fixed number called the common ratio.

In an arithmetic sequence, each term is equal to the previous term plus or minus a constant called the common difference.

In your problem we have a sequence of numbers that appears to be decreasing in value, but on the surface it doesn't appear to be by any constant number... but if you look closely, the denominator 34 is exactly twice the other denominator 17. This would lead me to look at a common denominator to see if anything takes shape...

9/17 = 18/34
15/34
6/17 = 12/34
9/34

Now we see that each number is the previous number minus 3/34, so we have a common difference of 3/34.

This would match the definition of an arithmetic sequence and NOT a geometric sequence.

Answer:

-\cos nw_0t

Step-by-step explanation:

We can use the double angle identity for sine.

\sin (A+B)=\sin A \cos B+\sin B\cos A

The given expresion is

\sin (nw_0t-90)

We apply the identity to get:

\sin (nw_0t-90)=\sin nw_0t \cos 90-\cos nw_0t \sin 90

We simplify to obtain;

\sin (nw_0t-90)=\sin nw_0t (0)-\cos nw_0t (1)

This simplifies to:

\sin (nw_0t-90)=-\cos nw_0t The correct answer is D
