Answer:
a) For this case we can use the fact that 
And for this case since we ar einterested on
and we know that the if we are below the y axis the sine would be negative then:

b) From definition we can use the fact that
and we got this:

We can use the notabl angle
and we know that :

Then we know that
correspond to 225 degrees and that correspond to the III quadrant, and we know that the sine and cosine are negative on this quadrant. So then we have this:

Step-by-step explanation:
For this case we can use the notable angls given on the picture attached.
Part a
For this case we can use the fact that

Part b
From definition we can use the fact that
and we got this:

We can use the notabl angle
and we know that :

Then we know that
correspond to 225 degrees and that correspond to the III quadrant, and we know that the sine and cosine are negative on this quadrant. So then we have this:

, that is D

Answer:
$58x.20=11.6
$58.00+11.60= $69.60
Step-by-step explanation:
Answer:The answer is 40 apples.
Step-by-step explanation:
It takes 10 apples to make a gram of fat. Multiply the 10 apples by 4 grams of fat to find that it takes 40 apples to make 4 grams of fat.
A deposit adds to the amount of a checking account.
So a deposit of $120.75 is + 120.75.
A withdraw subtracts from the amount of a checking account.
So a withdraw of $185.90 is - 185.90.
If the original amount is $425.82, you would simply add the amount of the deposit then subtract the amount of the withdraw.
425.82 + 120.75 - 185.90 = 360.67
So the amount in Christian's checking account after <span>a deposit if $120.75 and withdrawal of $185.90 is $360.67.
Answer:
$360.67
Hope this helps! :)
