5y - 2x + 1 = 0.
5y = 2x-1.
y = 2/5 x - 2/5
this tells us that tan(theta) = 2/5
sin(theta)/sqrt(1-sin^2(theta)) = 2/5
x/sqrt(1-x^2)=2/5
x^2/(1-x^2)=4/25
25x^2=4-4x^2
29x^2=4
x^2=4/29
x = -2/sqrt(29) because quadrant III
cos(x) = sqrt(1-4/29) = -5/sqrt(29)
tan(theta)=2/5
cos(theta)=-5/sqrt(29)
sin(theta)=-2/sqrt(29)
cot(theta)=5/2
sec(theta)=-sqrt(29)/5
csc(theta)=-sqrt(29)/2
I think your answer should be 100 cm...
Hope this helps
Hello! So, with Adian having a goal to lose 5% of his body weight, that means he will still have 95% of it left. The variable "w" represents the current amount of his weight. Multiplying by 1 will still give you his weight. Suppose he weighs 200 pounds. You plug in that as "w". Then, you would multiply that number by 5% (0.05) to see how much he would need to lose. 200 * 0.05 is 10. 200 - 10 is 190. Multiplying any number by 1 will get you to the same number. B and C are out, because they are basically the same equation, even when the "w" in answer choice C is distributed. A is out, because it shows the way the problem would be set up. D does not represent, because 1 is not his weight and it does not give a realistic answer on how much he needs to lose and weigh. Therefore, the answer is D.
First answer is A
Second answer is C
I believe B is the answer
