Answer:

The answer is

r =  -  \frac{va}{v - e}

Step-by-step explanation:

You have to get rid of fraction first :

v =  \frac{er}{r + a}

v(r + a) = er

vr + va = er

Next, you have to move all the r-variables to one side :

vr + va = er

vr - er =  - va

Lastly, make r the subject :

vr - er =  - va

r(v - e) =  - va

r =  -  \frac{  va}{v - e}

Answer:

r = va/(e - v)

Step-by-step explanation:

v = er/(r + a)

vr + va = er

va = er - vr

va = r(e - v)

r = va/(e - v)

The arc angle AC is measured as 55 degrees.

<h3>How to find arc angle?</h3>

If two secant intersect in the exterior of a circle, then the measure of the angle formed is half the positive difference of the arcs intercepted.

Therefore, the secants intersect outside the circle at point E.

The arc angle AC can be found as follows:

Therefore,

m∠BED = 1 / 2 (arc angle AC - arc angle BD)

arc angle AC = x

arc angle BD = 23 degrees.

m∠BED = 16 degrees.

m∠BED = 1 / 2 (arc angle AC - arc angle BD)

16 = 1 / 2 (x - 23)

16 = 1 / 2x - 23 / 2

16 + 11.5 = 0.5x

27.5 = 0.5x

x = 27.5 / 0.5

x = 55 degrees.

Therefore,

arc angle AC = 55 degrees.

What are the domain and range for this graph?
RideAnS [48]

ANSWER

c. Domain: [0,18]

Range: [0,360]

EXPLANATION

The domain refers to the values of x for which the function is defined.

The given straight line graph is defined for x=0 to x=18.

Hence the domain is [0,18]

The range refers to the values of y for which x is defined.

The graph is defined for y=0 to y=360.

The range is [0,360]
