Mathematics

KATRIN_1 [288]4 years ago
6 0

Step-by-step explanation:

cot(x) cos(x) + cot(x) = 0

cot(x) (cos(x) + 1) = 0

cot(x) = 0 or cos(x) = -1

cot(x) = 0

x = π/2, 3π/2

x ≠ 0, π

cos(x) = -1

x = π

Therefore, the answer is x = π/2, 3π/2.

What is 24.9% in decimal form ?
Sati [7]

Answer: 0.249

Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.

We can think of 24.9% as the ratio 24.9 to 100 or 24.9 ÷ 100.

Remember that dividing by 100 moves the decimal point two places to the left so 24.9 ÷ 100 will move the decimal point two places to the left which would give us .249 or 0.249.

Therefore, 24.9% can be written as the decimal 0.249.
