What is the approximate height of the building? Round to the nearest tenth of a foot.
22.5 feet
Is the work shown in the simplification below correct? Explain.
Specifically, the student failed to notice that the terms xy and yx are like terms. In algebra, when terms are multiplied, the order of the variables do not matter; they are similar. Thus, the simplified expression should have been 2xy - 2x -3y.
Select all that have negative values.
csc(5pie/4) csc 340 degrees sec 120 degrees
A 26-foot long ladder is leaning against a building at a 60° angle with the ground. Which of the following equations can you use to find the height of the building, h?
csc(60)=26/h
Select all that are undefined.
csc(pie) cot(pie) csc(0 degrees) sec(90 degrees)
Simplify: cos(θ) csc(θ)/sin(θ) cot(θ)
csc(θ)
Evaluate: sec (5π/4)
sqrt -2
Evaluate: cot (π/3)
sqrt 3/3
