Histogram can be drawn for equal and unequal classes. True/False

An electrician needs to run a cable from the top of a 40-foot tower to a transmitter box located 30 feet away from the base of

grin007 [14]

The cable should be 50 feet.

If you draw the picture, you will see that you have a right triangle.

Let's just use the Pythagorean Theorem to find the hypotenuse (or cable).

30^2 + 40^2 = c^2
2500 = c^2
50 = c

The initial population of a town in the year 2010 was 20 000. By 2014, the population had grown exponentially to 32 500 people.

stiv31 [10]

Answer:

P = 20000×1.625^(n/4)

Step-by-step explanation:

An exponential equation can be written using the given data:

value = (initial value)×(growth factor in period)^(n/(period))

Here, the growth is by a factor of 32500/20000 = 1.625, and the period is 4 years. Then your exponential equation is ...

P = 20000×1.625^(n/4)

Hey what's the answer ? <img src="https://tex.z-dn.net/?f=%28x%20-%20y%29" id="TexFormula1" title="(x - y)" alt="(x - y)"

Varvara68 [4.7K]

Answer:

 -1

Step-by-step explanation:

here's your solution

=> The value of x = 1

=> The value of y = 2

=> we need to find ( x - y)

=> so, put the value of above variables in it

=> hence, (1 - 2) = - 1

=> - 1 is correct answer

hope it helps

Answer:

Step-by-step explanation:

a) 1) Polynomial is closed under addition. In polynomial addition, only the coefficient change and variables and it powers does not change.

Example: Add 3x² - 2x + 7 and -2x² - 5x + 3

3x² - 2x + 7 - 2x² - 5x + 3 = 3x² -2x² - 2x - 5x + 7 + 3

= x² - 7x + 10

2)Polynomial is closed under addition. In polynomial subtraction, only the coefficient change and variables and it powers does not change.

Example: Subtract 3x - 2 from 4x + 2

4x + 2 - (3x - 2) = 4x + 2 - 3x + 2 = 7x + 4

3) Polynomial is closed under multiplication. In this, exponents of the variables are added according to the exponent rule. As the exponent of polynomials are whole numbers and whole numbers are closed under addition, the result will be a whole number.

-2x³ * 3x² = $-3*x^{3+2}=-3x^{5}$

4) Polynomial is not closed under multiplication. In division, we may get a negative exponent. So, it is not closed under division.

$\dfrac{x^{4}}{x^{9}}=x^{4-9}=x^{-5}\\\\x^{-5} \ is \ not \ a \ polynomial.$
