Answer:
1+2a
Step-by-step explanation:
To find the midpoint, add the two points together and divide by 2
(1+ 1+4a) /2 = (2+4a)/2 = 2/2 + 4a/2 =1 +2a
The trigonometry ratios are cos(θ) = -7/√58, sec(θ) = -√58/7 and cot(θ) = -7/3
<h3>How to determine the trigonometry ratios?</h3>
The point on the terminal side is given as:
(x, y) = (-7, 3)
Start by calculating the hypotenuse using:
So, we have:
Evaluate
The cosine is then calculated using:
cos(θ) = x/h
This gives
cos(θ) = -7/√58
The secant is then calculated using:
sec(θ) = 1/cos(θ)
This gives
sec(θ) = -√58/7
The cotangent is then calculated using:
cot(θ) = cos(θ)/sin(θ)
Where
sin(θ) = y/h
So, we have:
sin(θ) = 3/√58
So, we have:
cot(θ) = (-7/√58)/(3/√58)
This gives
cot(θ) = -7/3

Answer:
-125/27
Step-by-step explanation:
(-3/5)^-3= 1÷(-3/5)³
=1÷(-3³/5³)
=1÷(-27/125)
=1×(125/-27)
=-125/27
