Answer:

45.3 hours

Step-by-step explanation:

We are going to find the circumference of Earth's equator with $2\pi r$

First let's find the radius

Diameter = 7926

Radius = 7926/2 = 3963

Now use the the formula

$2\pi 3963=24900.26337$

24900.26337 ÷ 550 = <u>45.27320613</u>

Answer:

It would take around 7.2 hours!

Step-by-step explanation:

You need to find out what half of the equator is.

$\frac{7,926}{2}= 3,963$

Then you divide the mph (550) and the amount of miles. (3963)

$\frac{3,963}{550} = 7.205454545454545‬$

1-use (x-y) = set the distance from focus to the point equal to the distance from directrix to the point

2- $\sqrt{(x+1)^{2}(y-2)^{2}$ = square both sides and simplify equation

3- $\sqrt{(x-5)^{2} }$ =choose a point on the parabola

4- $\sqrt{(X-5)^{2} }$ 4- $\sqrt{(X+1)^{2}+(Y-2)^{2} } =\sqrt{(X-5)^{2} }$ = =find the distance from the focus to the point of the parabola

5- $(X+1)^{2}+(Y-2)^{2}=(X-5)^{2}$ =write the equation of the parabola

$Y^{2} -4Y+4=-12X+24$

6- $X= -\frac{Y^{2} }{12}+\frac{Y}{3}+\frac{5}{3}$ =find the distance from the point of the parabola to the directrix

Point G is located at (6, 2) on the coordinate plane. Point G is reflected over the y -axis to create point G^ prime . What orde

Lilit [14]

Answer:

The ordered pair that best describes the location of G' is (-6,2).

Step-by-step explanation:

Reflecting a point over the y-axis:

When a point (x,y) is reflected over the y-axis, it's x coordinate is multiplied by -1, while the y-coordinate stays the same. Thus:

(x,y) -> (-x,y).

Point G is located at (6, 2)

When reflected over the y-axis:

G'(-6,2).

The ordered pair that best describes the location of G' is (-6,2).
