The complete question in the attached figure

we know that
[arcs rc +arc cs arc sm]---------------> they take up half a circle-------->180°
<span> they are all congruent
so
divide 180 by 3 ----------------> 180/3=60</span>°


Find the length of arc rc=60°<span>

if 360</span>°----------------> (2*pi*7) length of circumference 
60° -------------------> X
<span>X=60*2*pi*7/360------------> 7.327 units

the answer is
</span>the length of arc rc= <span>7.33 units

</span>

In one U.S.​ city, the taxi cost is $2 plus $0.50 per mile. If you are traveling from the​ airport, there is an additional charg
mario62 [17]

Answer:

60 miles

Step-by-step explanation:

the equation for the cost for traveling from the airport can be represented by y= .50x + 2 + 6

where y is the final cost and x is the amount of miles. plug in 38 to y to get 38 = .50× +2 + 6. Solve for x.

38-6 =.50× +2

32 =.50x +2

32-2=.50x

30=.50x

30/.50=x

60=x

therefore, the 60 miles is how far you can go with $38

Estimate 726 Times 5
tester [92]

It's too easy just to calculate the actual value:

726 × 5 = 726 × 10/2 = 7260/2 = 3630

_____

You might estimate the value as 700 × 5 = 3500. You might estimate that to be low by 26/700 ≈ 4%, so about 140.

Plzzzz help! i will give brainliest 100 points! Let f(x) = 8x3 + 16x2 − 15 and g(x) = 2x + 1. Find f of x over g of x. A. 4 time
Blizzard [7]

Answer:

C. 4 times x squared plus 6 times x minus 3 minus 12 over the quantity 2 times x plus 1

Step-by-step explanation:

f(x) = 8x^3 + 16x^2 − 15

g(x) = 2x + 1.

f(x) / g(x) = (8x^3 + 16x^2 − 15) / (2x + 1)

Using long division

The y-intercept of (2,5) and (4,4)
wolverine [178]
First let's find the slope of line joining (2, 5) and (4, 4)

Assuming points  (x₁, y₁) and (x₂, y₂)

Slope = (y₂ - y₁) / (x₂ - x₁)

Slope = (4 - 5) / (4 -2) =  -1/2 = -0.5

From equation of line:     y = mx + c

y = -0.5x + c

Using the point (2 , 5) as passing through y = -0.5x + c

x = 2, y = 5

5 = -0.5*2 + c

5 = -1 + c

5 + 1 = c

6 = c

c = 6

Therefore the y-intercept which is c = 6

y-intercept = 6

Hope this explains it.
