How are the units of measurement called radiance related to the radius of a circle?

Mathematics
1 answer:
Pavlova-9 [17]3 years ago
8 0

Answer:

By definition, considering a unit circle (circle centered at origin and of radius 1) the length of an arc is equal to the measurement in radians (the SI unit for measuring angles) of the angle that it subtends (to be opposite to). The length of the arc is equal to the radius of the circle.

Suppose that a function​ f(x) is defined for all real values of x except at xequals=c. can anything be said about the existence
Margaret [11]

we are given that

f(x) is defined for all values of x except at x=c

Limit may or may not exist

case-1:

If there is hole at x=c , then limit exist

case-2:

If there is vertical asymptote at x=c , then limit does not exist

Examples:

case-1:

\lim_{x \to c} \frac{x^2-cx}{(x-c)}

We can simplify it

\lim_{x \to c} \frac{x(x-c)}{(x-c)}

=\lim_{x \to c} x

=c

so, we can see that limit exist and it's value defined

case-2:

\lim_{x \to c} \frac{1}{(x-c)}

Left limit is

\lim_{x \to c-} \frac{1}{(x-c)}

=-\infty

Right Limit is

\lim_{x \to c+} \frac{1}{(x-c)}

=+\infty

so, we can see that left limit is not equal to right limit

so, limit does not exist

a circle has a radius of 7ft. Find the radian measure of the central angle 0 that intyercepts an arc of length 16ft
Iteru [2.4K]

Answer:

2.29 rads

Step-by-step explanation:

The  length of the arc of a circle of radius r is given by;

l = rθ            ---------------------------(i)

Where;

l = length of the arc

θ = central angle o that intercepts that arc and measured in radians.

From the question:

l = 16ft

r = 7ft

Substitute these values into equation (i) as follows;

16 = 7θ

Make θ subject of the formula

θ = \frac{16}{7}

θ = 2.29    

Therefore, the radian measure of the central angle is 2.29 rads

Find the measure of the largest angle in the triangle shown . PLS HELP
Andre45 [30]

Answer:

72°

Step-by-step explanation:

So the three angles of a triangle always add up to 180°. This means that

15x + 21x + 24x = 180

This becomes:

60x = 180

And solves as:

x = 3

The largest angle has to be the one marked with 24x because it has the largest coefficient and x is a constant.

24x = 24(3) = 72

The measure of the largest angle in the triangle is 72°.
