Acircle has a radius of 5ft and an arc of length 7 ft is made by the intersection of the circle with a central angle. which equation gives the measures of the central angle q?

× π10 = 7

Explanation:

The formula to find arc length is ×

Simply plug in radius and arc length to get your equation.

Central angle = 80.21°

Step-by-step explanation:

The arc length in circle is the product of radius and central angle made by the arc in radians.

That is

              l = rθ

Here given the values r = 5 ft and l = 7 ft

Substituting

             7 = 5 x θ

             θ = 1.4 radians

Central angle = 80.21°

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
