A central angle in a circle with a radius of 3cm intercepts an arc with a length of 6cm. What is the radian measure of the central angle?

Answers

The correct answer for the question that is being presented above is this one:

Radian Measure can be acquired by using the formula
Radian Measure = arc length / radius
Radian Measure = 6 cm / 3 cm
Radian Measure = 2 rad.

Answer:

The correct answer for the question that is being presented above is this one:

Radian Measure can be acquired by using the formula

Radian Measure = arc length / radius

Radian Measure = 6 cm / 3 cm

Radian Measure = 2 rad.

What is trigonometry?

The field of mathematics is concerned with the relationships between triangles' sides and angles, as well as the related functions of any angle.

The given data in the problem is;

$\rightarrow \rm (tan((\theta)/(2) )(-5sin\theta)\n\n \rightarrow (sin (\theta)/(2) )/(cos (\theta)/(2)) * - (2 sin n (\theta)/(2) * {cos (\theta)/(2))$

$\rightarrow - (2 sin ^2 (\theta)/(2))\n\n -1+cos \theta$

The given expression is equivalent to (-1 + cosθ).

Hence,option B is correct.

How do I find the percent of 38% of 50

Answers

50 × .38 = 19 50 - 19 = 31 so 38% of 50 is 31

First calculate your percent as: 1-0.38=0.62. Then, multiply 0.62 by 50= 31. Your answer is 31

In the function f(x) = 4(x2 − 6x + ____) + 20, what number belongs in the blank to complete the square?

Answers

f(x) = 4(x² - 6x + ___) + 20

completing the square.

a² + 2ab + b²

a² = x² = x * x
2ab = -6x = 2*x* -3
b² = -3² = 9

f(x) = 4(x² - 6x + 9) + 20
f(x) = 4x² - 24x + 36 + 20
f(x) = 4x² - 24x + 56

Answer:
