Answer: The opposite of 2.5 is -2.5.

Step-by-step explanation:

Hi, to answer this question we have to understand what is the opposite number of a number.

The opposite number of a certain number is the same number but in the negative form (if the original number is a positive number ).

In this case, the opposite of 2.5 is -2.5.

Feel free to ask for more if it´s necessary or if you did not understand something.

Answer:

2 a

Step-by-step explanation:

Possible derivation:

d/dx(2 a x + 2 a y)

Differentiate the sum term by term and factor out constants:

= 2 a (d/dx(x)) + d/dx(2 a y)

The derivative of x is 1:

= d/dx(2 a y) + 1 2 a

The derivative of 2 a y is zero:

= 2 a + 0

Simplify the expression:

Two trains, Train A and Train B, simultaneously depart Station A and Station B. Station A and Station B are 252.5 miles apart fr

omeli [17]

-- The trains start moving at the same time.

-- The space between them is initially 252.5 miles.

-- They reduce the distance between them at the rate of (124.7+253.5)=378.2mph.

-- It will take them (252.5 / 378.2) = 0.6676 hour to meet.

That's 40min 3.49sec .

-- After tooting and puffing toward each other for 8 minutes, they still have 32min 3.49sec to go before they meet each other. We're all hoping that they're on different tracks.

Compute the missing data in the table for the following exponential function f (x) = (one-fourth) Superscript x.

aliina [53]

Answer:

$F(4) = \frac {1}{256}$

Step-by-step explanation:

Given the following mathematical function;

$F(x) = \frac {1}{4^{x}}$

When x = 1

$F(1) = \frac {1}{4^{1}}$

$F(1) = \frac {1}{4}$

When x = 2

$F(2) = \frac {1}{4^{2}}$

$F(2) = \frac {1}{4*4}$

$F(2) = \frac {1}{16}$

When x = 3

$F(3) = \frac {1}{4^{3}}$

$F(3) = \frac {1}{4*4*4}$

When x = 4

$F(4) = \frac {1}{4^{4}}$

$F(4) = \frac {1}{4*4*4*4}$

$F(4) = \frac {1}{256}$

When x = 5

$F(5) = \frac {1}{4^{5}}$

$F(5) = \frac {1}{4*4*4*4*4}$

$F(5) = \frac {1}{1024}$
