Answer:

(x - 3)^{2} + (y + 2)^{2} = 121

Step-by-step explanation:

The equation of a circle has the following format:

(x - x_{0})^{2} + (y - y_{0})^{2} = r^{2}

In which r is the radius and the centre is the point (x_{0}, y_{0})

In this question:

Center at (3,-2), so x_{0} = 3, y_{0} = -2

Radius 11, so r = 11

Then

(x - 3)^{2} + (y - (-2))^{2} = 11^{2}

(x - 3)^{2} + (y + 2)^{2} = 121

Anna and Veronica are on the opposite sides of a tower of 160 meters height. They measure the angle of elevation of the top of t
MAXImum [283]

Answer: The distance between the girls is 362.8 meters.

Step-by-step explanation:

So we have two triangle rectangles that have a cathetus in common, with a length of 160 meters.

The adjacent angle to this cathetus is 40° for Anna, then the opposite cathetus (the distance between Anna and the tower) can be obtained with the relationship:

Tan(A) = opposite cath/adjacent cath.

Tan(40°) = X/160m

Tan(40°)*160m = 134.3 m

Now, we can do the same thing for Veronica, but in this case the angle adjacent to the tower is 55°

So we have:

Tan(55°) = X/160m

Tan(55°)*160m = X = 228.5 m

And we know that the girls are in opposite sides of the tower, so the distance between the girls is equal to the sum of the distance between each girl and the tower, then the distance between the girls is:

Dist = 228.5m + 134.3m = 362.8m

zimovet [89]

Answer:

C = 0.65M+19.65

Step-by-step explanation:

Given the the standard charge S (in dollars) given by the function

S = 0.40M + 15.75, where M is the number of miles driven.

Also the insurance charge I (in dollars) is given by the function

I = 0.25M + 3.90

If C is the total charge (in dollars) for a rental that includes insurance, then:

C = S + I

Substitute the given function into the expression:

C = 0.40M + 15.75 + 0.25M + 3.90

Collect like terms

C = 0.40M+0.25M+15.75+3.90

C = 0.65M+19.65

<em>Hence an equation relating C to M is expressed as C = 0.65M+19.65</em>
