The unit rate is another way of saying speed, so we divide the distance over the time. We can pick on any row

If we pick row 1, then, speed = distance/time = 90/2 = 45

Row 2 says the same thing: 135/3 = 45

So does row 3: 225/5 = 45

and so on

Because the speed is 45 mph, the unit rate is 45 miles in one hour. The term "unit" implies how much distance can be covered in one unit of time, in this case 1 hour.

You have the correct answer. Nice work.

The circle below is centered at the point (5 3 ) and has a radius of length 4 what is its equation
sleet_krkn [62]
The equation of the circle is may be expressed as, 
                           (x - h)² + (y - k)² = r²
where h and k are the abscissa and ordinates of its center, respectively, and r is radius. Substituting the given values to the equation above, 
                          (x - 5)² + (y - 3)² = 4²
Simplifying further the equation gives, 
                            x² + y² - 10x - 6y + 18

Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the Quadrilateral. Show your work. ( Plea
oksano4ka [1.4K]

Answer:

  • Shown Below.

Explanation:

opposite angles in a quadrilateral sum up to 180°

total interior angles in a quadrilateral is 360°

solve for x:

x - 2 + x + 2 = 180°

2x = 180°

x = 90°

solve for each angle:

1st

x + 2

90° + 2 = 92°

2nd

x - 2

90° - 2 = 88°

3rd

x - 10

90° - 10° = 80°

4th

360° - 80° - 88° - 92° = 100°

Which is the best approximation of the solutions to the system of equations graphed below?
Neko [114]

According to the direct inspection, we conclude that the best approximation of the two solutions to the system of <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)

<h3>What is the solution of a nonlinear system formed by two quadratic equations?</h3>

Herein we have two parabolae, that is, polynomials of the form a · x² + b · x + c, that pass through each other twice according to the image attached to this question. We need to estimate the location of the points by visual inspection on the <em>Cartesian</em> plane.

According to the direct inspection, we conclude that the best approximation of the two solutions, that is, the point where the two parabolae intercepts each other, to the system of two <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)
