Assuming each tweet reaches the max of 140, there would be 56 billion drops of water daily. This would equate to 738,681.7 gallons of water or 98,870.4 cubic feet. This amount of drops of water could fill up almost half of the Goodyear blimp

Determine the domain of (f/g)(x) when f (x)=1/x and g (x)=sqrtx+5
mash [69]

we are given

f(x)=\frac{1}{x}

g(x)=\sqrt{x+5}

Calculation of (f/g)(x):

(\frac{f}{g})(x)=\frac{f(x)}{g(x)}

now, we can plug values

(\frac{f}{g})(x)=\frac{\frac{1}{x}}{\sqrt{x+5}}

now, we can simplify it

(\frac{f}{g})(x)=\frac{1}{x\sqrt{x+5}}

Domain:

we know that domain is all possible values of x for which any function is defined

function will be undefined when denominator =0

x\sqrt{x+5} =0

x=-5,x=0

we are given sqrt function

and we know that value inside sqrt will always be greater than 0

x+5>0

x>-5

so, domain will be

borishaifa [10]

Answer: 1102 minutes

Explanation: Let x be the number of minutes Jim used 105.60 = 75 + 0.30 ( x − 1000 ) ⇒ 105.60 = 75 + 0.30 x − 300 ⇒ 105.60 = 0.30 x − 225
