For any x in Real numbers, [x] is the greatest possible integer smaller than x, or equal to x if x is an integer.

According to this,

<span>[2.4] is the greatest integer , smaller than or equal to (so non greater) 2.4. This number is 2

similarly,  </span>[-2.4] is the greatest integer , smaller than or equal to (so non greater) -2.4. This number is -3.


Answer: 

A) <span>Because 2 is the greatest integer not greater than 2.4 and –3 is the greatest integer not greater than –2.4. </span>

svetoff [14.1K]
You are correct!

Step 1:Write what you know
Madeline's Height: 6 ftMadeline's Shadow: 108 in
Friend's Height: X (we use X as a variable because his height is unknown)Friend's Shadow: 108 in - 1.5 ft                              108 in - 18 in                                 90 in
Step 2:Set up proportions
6          x----- = -----108      90 
Step 3:Cross Multiply & Solve
108x = 540x = 5 ft tall

An element with mass 670 grams decays by 27.3% per minute. How much of the element is remaining after 9 minutes, to the nearest
ArbitrLikvidat [17]
There will be 38 grams remaining.

The equation would be of the form
y = a(1+r)ˣ, where a is the initial value, r is the rate as a decimal number, and x is the amount of time.  Using our values from the problem, we have:

y = 670(1-0.273)^9 = 670(0.727)^9 = 38

I think I'm struggling to find the inverse for this one:
USPshnik [31]
Recall that the derivative of a constant is 0.

\bf y=x^2-4x+4\implies y=(x-2)^2\implies \stackrel{inverse}{x=(y-2)^2}&#10;\\\\\\&#10;\sqrt{x}=y-2\implies \sqrt{x}+2=y\implies x^{\frac{1}{2}}+2=y&#10;\\\\\\&#10;\cfrac{1}{2}x^{-\frac{1}{2}}+0=\cfrac{dy}{dx}\implies \cfrac{1}{2}x^{-\frac{1}{2}}=\cfrac{dy}{dx}
