Answer:

123,456,789 = 1.23456789\times 10^8

Step-by-step explanation:

It is required to find the value of the missing exponent in the below value i.e.

123,456,789 = 1.23456789\times 10^x

Let the exponent is x.

Any number can be written in the scientific notation as :

N=a\times 10^b

a is a real number

b is any integer

In this case, the decimal is applied before 8 numbers. It means that the value of x is 8.

What is the multiplicative rate of change of the<br> function?
BartSMP [9]

Answer:

We know that the multiplicative rate of change of a function is the number by which each next term of an exponential function is increasing or decreasing. We can find multiplicative rate of change by dividing any term of the function by its previous term.

I need help with 33 and 34
kenny6666 [7]
EDIT: Picture

33) When adding matrices, just add the numbers that are in the same spot. In this problem we are given A and C, and we are asked to find B if A + B = C

So B = C - A

\left[\begin{array}{ccc}2&-1&-3\\1&4&-2\\\end{array}\right] - \left[\begin{array}{ccc}4&9&-2\\-3&5&7\\\end{array}\right] = \left[\begin{array}{ccc}-2&-10&-1\\4&-1&-9\\\end{array}\right]

34) When multiplying matrices, the number of columns in the first matrix needs to be the same as the number of rows in the second matrix. Then the outcome will have the same number of rows as the first matrix and same number of columns as the second matrix. In this case, the result will be a 2x2.

A base of ten raised to a negative exponent corresponds to a number that is-
Masteriza [31]

Answer:

A base of ten raised to a negative exponent corresponds to a number that is between 0 and 1.

Step-by-step explanation:

A base of ten raised to a negative exponent, say - 1 will correspond to the number, 10^{- 1} = \frac{1}{10^{1}} = \frac{1}{10}.

Again, a base of ten raised to a negative exponent, say - 2 will correspond to the number, 10^{- 2} = \frac{1}{10^{2}} = \frac{1}{100}.

{Since we know the property of exponents as x^{- a} = \frac{1}{x^{a}}}

Therefore, all those numbers are between 0 and 1.

Hence, a base of ten raised to a negative exponent corresponds to a number that is between 0 and 1. (Answer)
