Answer:
Algebraic expression representing number of coffee B = 100-x
Step-by-step explanation:
An algebraic expression is an expression that contains unknowns denoted with alphabets or symbols and natural numbers.
Coffee blend is 100 pounds and x represent number of pounds of coffee A
Hence coffee B = 100-x
Algebraic expression representing number of coffee B = 100-x
We know that
sin²x+cos²x=1
so
clear cos x
cos x=(+/-)√[1-sin²x]
in this problem
<span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive
</span>sin o=2/5
cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5
the answer is
cos o=√21/5
Step-by-step explanation:
Opposite angles in a cyclic quadrilateral are supplementary.
Therefore 3c = 4d = 180°, c = 60° and d = 45°.
Step-by-step explanation:
know the normal large sample condition is not met and also there are outliers
