2) Evaluate 9 X 364 – 9 X 125 – 9 X 39 without the use of your calculator
Brums [2.3K]

Answer:

<em>9*364 - 9*125 - 9*39 = 1,800</em>

Step-by-step explanation:

<em>Mental Calculation</em>

If we detect known patterns in the calculations, we could easily give their results without the use of calculators.

We are given the expression to evaluate:

9*364 - 9*125 - 9*39

The first thing to note is the 9 is a common factor of all terms, thus we take it out:

9*(364 - 125 - 39)

The negative numbers can be easily added

     125

+     39

------------

     164

Now our expression is much easier:

9*(364 - 164)

The subtraction of 364-164 is 200, thus the result of the operations is:

9*200. We only need to recall 9*2=18 and add two zeros to get 1,800, thus:

9*364 - 9*125 - 9*39 = 1,800

Find the inverse function of : f(x)=2x-6.<br>f(x)=2x−6.
mihalych1998 [28]
\displaystyle f(x) = 2x - 6 \iff y = 2x - 6 \implies x = 2y - 6 \implies x+ 6 = 2y \implies \\  \\&#10;y = \frac{1}{2}x + 3 \implies \bf f^{-1}(x) = \frac{1}{2}x + 3

A satelite is 5,400 miles from the horizon of earth. Earths radius is about 4000 miles. Find the approximate distance the sateli
kakasveta [241]

Answer:

The distance of Satelite from the earth's surface = 2720.12 miles

Step-by-step explanation:

Below is the calculation for distance:

Use Pythagorean theorem

Distance, d² = 5400² + 4000²

d² = 45160000

d = 6720.12

Subtract the radius to find the distance from earth's surface.

Distance = 6720.12 - 4000 = 2720.12

The distance of Satelite from the earth's surface = 2720.12 miles
