Answer:
cscα=√2
Step-by-step explanation:
Problem: If sinα-cosα=θ find cscα
Solution:
sinα-cosα=θ
sinα=cosα
sinα=sin(90-α)
If α<90, then:
α=90-α
2α=90
α=45°
sin(45°)
1/sin(45°)
csc(45°)
√2
Therefore, cscα=√2 if sinα-cosα=θ
Answer:
(7x+3/4*[x-1])^2
Step-by-step explanation:
The square of the sum of 7 times x. and 3 divided by 4 times the difference of x and 1. This would mean that (7x+3/4*[x-1])^2 You would perform x - 1 in the [] first, which is why they are in the extra brackets. The whole thing is squared, so it is all in parenthesis, being squared. It says 3/4 into x-1. This would mean it's multiplying into x-1.
Answer:
1mm, 1cm, 1m, 1km.
Step-by-step explanation:
x equals negative 8 and negative 4
parallel lines, have the same exact slope, hmmm what is the slope of y = -2/3 x + 1/3 anyway? well, low and behold, the equation is already in slope-intercept form, therefore
has a slope of -2/3.
so we're really looking for a line whose slope is -2/3 and runs through 9,4.
