Is -1 ⅐ a natural, whole, integer, rational or irrational number?

lana66690 [7]

Answer:

Rational

Step-by-step explanation:

okay so a natural number is anything like 1,2,3,4...etc.

a whole number is like a natural number but includes 0's

an integer is numbers that can have both positive and negative numbers

but keep in mind all of these are whole numbers or can be made into a whole number (not including natural numbers)

this leaves...

Rational

now here is a word of advice every mixed number and fraction is rational because its already in a solved and complete form but a decimal that could be solved like 0.77777 or 0.345 with a line over it or 64 squared

Irrational

a number that has no end and cant be solved like 0.86866968..... or 38 squared

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.
