Evaluate and simplify the expression when a = 4 and b = -1.

Gwar [14]

Answer:

$\frac{3}{2}$

Step-by-step explanation:

$\frac{5 - 2(a + 3b)}{2}$

substitute a = 4 and b = -1

$= \frac{5 - 2(4 + 3( - 1))}{2}$

expand and simplify the numerator

$= \frac{5 - 2(4 - 3)}{2}$

$= \frac{5 - 2(1)}{2}$

$= \frac{5 - 2}{2}$

$= \frac{3}{2}$

If the cotangent and tangent are reciprocals of each other, then what is the cotangent of an angle if the tangent of the same an

Ad libitum [116K]

Answer:

The cotangent of the angle will be b/a

Step-by-step explanation:

Since the cotangent and tangent are reciprocals of each other and the tangent of the same angle is a/b where a and b are not zero,

then the cotangent will be the reciprocal of the value of the tangent

= 1 / (a/b)

= 1 x (b/a)

= b/a
