If the tangent value is 33*, the cotangent value to the hundredths degree is: 0.65 0.649 1.54 1.540
iragen [17]

Answer:

1.54

Step-by-step explanation:

The cotangent value is referred to as the reciprocal or the opposite of a given tangent value. Cotangent is also referred to as it's short form called cot

Mathematically, Cotangent (cot) = 1/tan

In the above question, we are given a value where:

tan = 33°

Cotangent (cot) = 1/tan 33°

Cotangent (cot) = 1.5398649638

We are told to approximate to the nearest hundredth

= 1.54

What is the slope of the line that passes through the points ( −8,−1) and (-12,-2)
omeli [17]

Answer:

1/4

Step-by-step explanation:

We can find the slope of a line given two points from the formula

m = (y2-y1)/(x2-x1)

   = (-2--1)/(-12--8)

   = (-2+1)/(-12+8)

    =-1/-4

   = 1/4
