48.0858.

First you multiply 44.94 and .07 (the decimal equivalent of 7%) which gives you 3.1458. You take 3.1458 and add it to 44.94 (since it's an additional fee) and that gives you 48.0858

The equation of a circle is x2+y2−12x+6y+20=0 .

Rufina [12.5K]

Answer:

The radius is r=5 units

Step-by-step explanation:

we know that

The equation of the circle in standard form is equal to

$(x-h)^{2}+(y-k)^{2}=r^{2}$

where

(h,k) is the center and r is the radius

we have

$x^{2}+y^{2}-12x+6y+20=0$

Convert to standard form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$(x^{2}-12x)+(y^{2}+6y)=-20$

Complete the square twice. Remember to balance the equation by adding the same constants to each side

$(x^{2}-12x+36)+(y^{2}+6y+9)=-20+36+9$

$(x^{2}-12x+36)+(y^{2}+6y+9)=25$

Rewrite as perfect squares

$(x-6)^{2}+(y+3)^{2}=5^{2}$

therefore

The center is the point (6,-3) and the radius is r=5 units

Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. What is the latitude of

erica [24]

Answer:

${\theta}=12.53 degrees$ ≈13degrees

Step-by-step explanation:

It is given that Two cities A and B are 1400km apart and lie on the same N-S line. The latitude of city A is 23 Degrees. Then,

Using the formula, $S=r{\theta}$ where s is the distance between the two cities and r is the radius of the earth,thus substituting the values, we get

$1400=6400{\theta}$

⇒ ${\theta}=\frac{14}{64}$

Therefore, ${\theta}=\frac{14}{64}{\times}\frac{180^{{\circ}}}{{\pi}}$

⇒ ${\theta}=\frac{2520}{200.96}$

⇒ ${\theta}=12.53 degrees$

Thus, the latitude of B is=12.53 degrees≈13degrees
