What is the multiplication and division property of exponets?

Alexandra [31]

Mult
$(x^m)(x^n)=x^{m+n}$

div
$\frac{x^m}{x^n} =x^{m-n}$

baseically, x is the base, and m and n are bases

you can only use this property if bases are same

baseically
multiply means add powers
divide means subtract bottom power from top

Find cos(2115°) and sin(2115°). Identify the measure of the reference angle.

ivolga24 [154]

Answer:

Cos(2115°) =1/√2

Sin(2115°) = -1/√2

Step-by-step explanation:

We have to find the values of Cos (2115°) and Sin (2115°).

Now, 2115° can be written as (23×90°+ 45°).

Therefore, the angle 2115° lies in the 4th quadrant where Cos values are positive and Sin values are negative.

Hence, Cos (2115°) = Cos(23×90° +45°) =Sin 45° {Since 23 is an odd number, so the CosФ sign will be changed to SinФ} =1/√2 (Answer)

Again, Sin (2115°) = Sin(23×90° +45°) = -Cos 45° {Since 23 is an odd number, so the SinФ sign will be changed to CosФ} = -1/√2 (Answer)

Now, the required reference angle is 45°. (Answer)

What is a bank statement

azamat

Answer:

A bank statement can be defined as a record of payments in and out of a bank account.

Step-by-step explanation:

For example, energy providers offer direct debit payments as the amount that is used each month may vary and they take the required amount at each bill. Standing orders are similar to a direct debit except that they are for a fixed amount.
