Step-by-step explanation:
cotangent is the reciprocal of a tangent
tanθ = 2
cotθ = 1/2
She can expect 70 to be ads since there is 10 times more emails so 7 times 10 is 70 so 70 ads
Answer:
≈ 78.55 cm
Step-by-step explanation:
Using the ratio of arc (AB) to circumference (C) is equal to the ratio of angle subtended at centre by arc AB to 360°, that is
= 
, that is
= ( cross- multiply )
110C = 8640 ( divide both sides by 110 )
C = 
≈ 78.55 cm ( to 2 dec. places )
The answer is 360 in² If you need to see work just tell me :)
If you equate both, the y is eliminated:
-6x-3 = -x+2
Simplify this to find x:
-5x = 5
x = -1
Fill in x=-1 in either equation:
y = --1 + 2 = 3
So (-1,3) is the solution, it is where the lines intercept.
