Can someone help me to solve this question sec(x)sin(x)-2sin(x)=0 [0,2pi) ? ASAP!!!!!

BigorU [14]

Answer:

x = 0, π/3, π, 5π/3

Step-by-step explanation:

sec(x)sin(x) - 2sin(x) = 0

factor out sin(x)

sin(x)[sec(x) - 2] = 0

then solve by splitting into two parts:

sin(x) = 0 and sec(x) - 2 = 0

x = 0, π and x = π/3, 5π/3 then plug in to original equation to check

There is a number that if you multiply it by 4 first, and then subtract 10 from the result, you get 14. What's the number.

polet [3.4K]

It's 6. 6 times 4 is 24, and 24 minus 10 is 14

1) Reflecting over y=x means $(x, y) \longrightarrow (y,x)$ . So, the coordinates of the image are:

$V(-3, 0) \longrightarrow V'(0,-3)\\\\W(-1,0) \longrightarrow W'(0, -1)\\\\U(-2,-5) \longrightarrow U'(-5,-2)\\\\X(3,-3) \longrightarrow X'(-3, 3)$

2) Rotating 90 degrees counterclockwise about the origin means $(x,y) \longrightarrow (-y,x)$ , so the vertices of the image are:

$W(0,-1) \longrightarrow W'(1,0)\\\\X(3,-1) \longrightarrow X'(1, 3)\\\\V(0,-3) \longrightarrow V'(3,0)\\\\Y(1, -5) \longrightarrow Y'(5, 1)$

3) The vertices of the image are:

$C(2,0) \longrightarrow C'(-2, -2)\\\\D(2, 5) \longrightarrow D'(-2, 3)\\\\E(5,4) \longrightarrow E'(1, 2)$
