Answer:
The six trig ratios at 3pi/2 are:
sin(3pi/2)=-1
cos(3pi/2)=0
tan(3pi/2) (undefined)
csc(3pi/2)=-1
sec(3pi/2) (undefined)
cot(3pi/2)=0
Step-by-step explanation:
If tangent is undefined then cosine would have to be 0 given that tangent is the ratio of sine to cosine.
cosine is 0 at pi/2 and 3pi/2 in the first rotation of the unit circle.
3pi/2 satisfies the given constraint.
The six trig ratios are therefore:
sin(3pi/2)=-1
cos(3pi/2)=0
tan(3pi/2)=-1/0 (undefined)
Reciprocal values:
csc(3pi/2)=-1
sec(3pi/2) undefined since cos(3pi/2)=0
cot(3pi/2)=0/-1=0
Answer:
OB. 12
Step-by-step explanation:
Since the die is a fair six-sided die and the question uses should... we know that a roll of "4" has a 1/6 chance to land every time the die is rolled.
1. 72 rolls * 1/6 chance to roll a 4 = 12 times
We multiply 763 by 0.29 which is 221.27.
Then we subtract that from 763.
763-221.27=541.73
So you would have about 542 brushes if they were originally decrease but 29%.
I hope this helps!
Answer:
D. 3200 square feet
Step-by-step explanation:
(2)(20)*(2)(40)=3200
The ratio in its simplest form is 7:4
