Answer: Zero

Why? When the line is flat right horizontal with not increase or decrease it is considered a zero slope. (NOT UNDEFINED, it is defined, it’s defined as zero)

a satellite's escape velocity is 6.5 mi/sec, the radius of the earth is 3960 mi, and the earth's gravitational constant is 32.2

Artyom0805 [142]

Answer:

$23.89x10^{6}$ ft

Step-by-step explanation:

$\frac{V^{2} }{R^{2} } = \frac{2g}{R+h} \\$ This is the formula to find satellite's escape velocity V , where R is earth's radius, h is the satellite's height from the earth surface and g is the earth's gravitational constant.

$R^{2}(R+h) \frac{V^{2} }{R^{2} } =R^{2} (R+h)\frac{2g}{R+h}$ (Multiplying to clear the fractions)

(R+h) $V^{2} =R^{2} 2g$

$R+h=\frac{2R^{2}g }{V^{2} }$

$h= \frac{2R^{2} g}{V^{2} } -R$

Now, we can determine height of satellite from the surface of the earth

by putting the values in above equation

$h= \frac{2 * (3960)^{2}*32.2 }{6.5^{2} } -3960\\h= 23.902 x10^{6} - 3960\\ h=23.89x10^{6} ft$

Compare and Contrast: Below are two expressions. Simplify each and then choose the statement that is true.

daser333 [38]

The correct answer to this question is The exponents on Expression #2 are greater than the exponents of Expression #1.

Expression #1
(3x^2) 3x^2
This is just equal to 9x^4.

Expression #2
(3x2)^2 x^2
This is just equal to
= 9x^4 * x2
= 9x^6

The exponent in expression 2 is greater than the exponent in expression 1

inna [77]

Answer:

A linear relationship (or linear association) is a statistical term used to describe a straight-line relationship between two variables. Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + b.

In the figure given, what is the value of x?

torisob [31]

Answer:

x = 30

Step-by-step explanation:

In the figure attached,

Two lines are parallel and one line having two adjacent angles (4x)° and (x + 30)° are the transverse.

Sum of interior consecutive angles = 180°

So the sum of these angles = 180°

(4x)° + (x + 30)° = 180°

(4x + x) + 30 = 180

5x + 30 = 180

5x = 180 - 30

5x = 150

x = 30

Therefore, value of x = 30
