What is 2580 divided by 20

Answers

Thisis a question of simple division. Only thing is the numerator is big and sodividing requires the numerator to be made small. For that purpose it isrequired to divide the numerator and denominator by 10 and then the numeratorbecomes small and can be divided by the denominator without the help ofcalculator.
2580 divided by 20 is what needs to be found.
2580/20 = 258/2
= 129
129 is the required answer and hopefully this will come toyour help.

3^2x3^9 simplify and write in exponential form

Answers

Answer:

$\sf 3 ^(11)$

Step-by-step explanation:

An exponent is a mathematical symbol that tells us how many times to multiply a base number by itself.

In this case:

To simplify 3² × 3⁹, we can use the following rule of exponents:

$\sf a^m * a^n = a^(m+n)$

Therefore, 3² × 3⁹ can be simplified as:

$\begin{aligned} 3^2* 3^9 & = 3^(2+9) \n\n &= 3^(11)\end{aligned}$

Therefore the answer in exponential form is: $\sf 3 ^(11)$

Answer:

$3^(11)$

Step-by-step explanation:

using the rule of exponents

• $a^(m)$ × $a^(n)$ = $a^((m+n))$

given

3² × $3^(9)$

= $3^((2+9))$

= $3^(11)$

The function f(x) = –(x – 20)(x – 100) represents a company’s monthly profit as a function of x, the number of purchase orders received. Which number of purchase orders will generate the greatest profit?20
60
80
100

Answers

Let us solve the following problem by substituting each value with x.

FIRST CHOICE
f(x) = -(20-20)(20-100)
= -(0)(-80)
= 0

SECOND CHOICE
f(x) = -(60-20)(60-100)
= -(40)(-40)
= -(-160)
= 160

THIRD CHOICE
f(x) = -(80-20)(80-100)
= -(60)(-20)
= -(-120)
= 120

LAST CHOICE
f(x) = -(100-20)(100-100)
= -(80)(0)
=0

The answers yielded 0, 160, 120, and 0, respectively.
Thus, the answer is 60.

Answer:

The answer is 60

Step-by-step explanation:

because when you plug in these numbers to the x, 60 is the greatest one.

Simplify the given expression below: (4 + 2i) − (1 − 7i) 5 − 5i 5 + 9i 3 + 9i 3 − 5i

Answers

The best way to think of complex numbers is through x and y coordinates, if a number is just on its own (real) think of it as the x ordinate. Conversely if the number is say 2i (imaginary), just think of it as the y=2.
So 4+2i - (1-7i) = 4+2i-1+7i = (4-1) + i(2+7) = 3 +9i
That can be though of as (3,9). A complex number is just two separate real numbers, a real part and an imaginary part.

The value of the complex expression will be 3 + 9i. Then the correct option is C.
