The area of the surface of a sphere is described by the formula S=4(3.14)r^2. The earth has a radius of 3960 miles and dry land
Stella [2.4K]

Answer: 57,512,581.63miles^2

Step-by-step explanation:

Substitute the value of the radius of the Earth into the formula given in the problem, where r is the radius, to obtain the surface area of the Earth:

S=4(3.14)r^2\\S=4(3.14)(3,960miles)^2\\S=196,960,896miles^2

The problem says that the dry land forms 29.2% of the Earth’s surface, therefore, multiply the surface area by \frac{29.2}{100}=0.292

Threfore, the area of dry land is the following:

S_{land}=(0.292)(196,960,896miles^2)=57,512,581.63miles^2

what is the slope intercept form of the equation of the line described by (-4,-5), parallel to y=-2x -5
Eddi Din [679]

Answer:

y = - 2x - 13

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x - 5 ← is in slope- intercept form

with m = - 2, thus

y = - 2x + c ← is the partial equation of the line

To find c substitute (- 4, - 5) into the partial equation

- 5 = 8 + c ⇒ c = - 5 - 8 = - 13

y = - 2x - 13 ← equation of line
