Katen [24]

Answer:

8 , 5 , 5.785

Step-by-step explanation:

y^2 - x^3

first just plug in the numbers and you get

(4)^2 - (2)^3

Multiply

16-8 and this equals 8

x1 + x^3 - y^2

same pattern plug in the numbers

(3)^(1) + (3)^3 - (5)^2

multiply

3 + 27 - 25

P

E

M

D

Addition

Subtraction so do 3+27 first and you get

30 - 25 = 5

x^4 / x^3 plug it in

(6)^4 / (6)^3

multiply

1269  / 216  

divide this and you get

5.875

2+cotA=1 homework help
Alex Ar [27]
2+\cot A=1\implies \cot A=-1\implies \tan A=-1

This happens whenever A=\dfrac{3\pi}4 or A=\dfrac{7\pi}4. More generally, \tan A=-1 whenever you start with one of these angles and add any multiple of \pi, so the general solution would be A=\dfrac{3\pi}4+n\pi, where n is any integer. (Notice that when n=1, you end up with \dfrac{7\pi}4.)
