Since we know side LK is equal to KN, and side LM is equal to NM, we can set the pairs equal to each other and solve for x.

<u>KN</u>
2y+5=y+10
2y=y+5
y=5

<u>NM</u>
3x-1=2x+6
3x=2x+7
x=7

From this, we can conclude that side KN=5 and side NM=7.

Let the unknown be x

$\sqrt{3} = 27^x$

$3^\frac{1}{2} = 3^{3x}$

Both the base number are 3, so we equate the exponent:

$\dfrac{1}{2} = 3x$

$x = \dfrac{1}{2} \div 3$

$x = \dfrac{1}{2} \times \dfrac{1}{3}$

$x = \dfrac{1}{6}$

Answer: 1/6

The difference in mail handled between 195 and 1965 is -5.4 x 10

<h3>What is the difference in mail handled?</h3>

The data on the pieces of mail handled by the United States Postal Service is written in scientific notation. Scientific notation is used to compress larger numbers into smaller numbers.

In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10. For example, 1 x 10² is equivalent to 100

Difference in mail handled = mail handled in 1995 - mail handled in 1965

(1.8 x $10^{11}$ ) - (7.2 x $10^{10}$ )

(1.8 - 7.2) x $10^{11 - 10}$

-5.4 x 10

4 Find a formula for the exponential function passing through the points (-2, 4/9) and (3, 108)

NemiM [27]

9514 1404 393

Answer:

f(x) = 4·3^x

Step-by-step explanation:

We assume the function will be of the form ...

f(x) = a·b^x

Substituting the given values, we can find 'a' and 'b'.

4/9 = a·b^(-2)

108 = a·b^3

Dividing the second equation by the first gives ...

108/(4/9) = b^(3 -(-2))

243 = b^5

b = 3 . . . . . . 5th root

Using the second equation, we can find 'a':

108 = a·3^3 = 27a

a = 108/27 = 4

The formula for the exponential function is ...

f(x) = 4·3^x

Due to inflation there were two demand increases. After the second increase the price for a certain item became twice as big as

slamgirl [31]

Consider, pls, this option:
1) let start price is 'x' and the 1-t increasing is 'y';
2) after the 1-t increasing new1_price is x(y+1);
3) after the 2-d increasing new2_price is 1.25x(y+1);
4) from another side, new2_price is '2x';
5) according to five items it is possible to make up an equation: 1.25x(y+1)=2x;
1.25(y+1)=2, y=8/5 -1=3/5=0.6.
0.6 means 60%.
Answer: 60%.
