<u>Your question: </u>given that sin(30)=1/2 and cos(30)=(sqrt3)/2, use trigonometric identities to find the value of cot(30)
The correct answer would be D 
Answer:
14
Step-by-step explanation:
Take the square root of 11650+14:
%:11650+14
108
So it’s a perfect square (108^2=11664).
The far right would be the correct answer.
<span>First step is find total height of all the figures expressed in feet:
Liem: 6 ft 2 inch = 6,167 ft
Eli: 5 ft 9 inch = 5,75 ft
Faith 6 ft
Simon: 5 ft 4 inch = 5,34 ft
To calculate the total height we need to know that 12 inches are 1 foot
6’2”+5’9”+6+5’4”= 22 ft 15 inch = 23 ft 3 inch
Another way is by adding decimal figurel:
6,167 + 5,75 + 6 + 5,34 = 23,25 feet
Then we know that 3 feet are 1 yard, so then total height is:
23,25 / 3 = 7,75 yards</span>
Kevin linear function is y = 3x + 1 while Jill function is y = 3x - 1
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Using the points (0, 1) and (2, 7), hence for Kevin:
y - 1 = [(7 - 1)/(2 - 0)](x - 0)
y = 3x + 1
Jill’s function has a y-intercept that is 2 less than the y-intercept, hence b = 1 - 2 = -1
Jill function is:
y = 3x - 1
Kevin linear function is y = 3x + 1 while Jill function is y = 3x - 1
