Mathematics
1 answer:
Blababa [14]3 years ago
6 0

Answer:

there is no solution for (0, 30°)

Step-by-step explanation:

six(x) = cos(x)

sin(x) - cos(x) = 0

(sin(x) - cos(x))^2 = 0

sin(t)^2 + cos(x)^2 - 2sin(x)cos(x) = 0

1 - sin(2x) = 0

sin(2x) = 1

2x = π/2 + 2πk -> k - any integer number

x = π/4 + πk

the smallest positive solution is π/4 = 45°. That means for range (0, 30°)

there is no solution

Use Inverse operations to solve the expression. Enter your answer in simplest form. y 1 =8 16​
vredina [299]
So we are trying to get the “y” alone, so to undo the division by -8, we will multiply both sides by -8, then simplify.

(-8) y/(-8) = (-8) 1/16

y = -8/16

and simplified:

y = -1/2
