Which expression is equivalent to 4^5x4^-2
Answer:
4^3
Step-by-step explanation:
When you are multiplying exponents with the same base (for this problem the base is 4) you add together the exponents. It is kinda hard to explain but that is just a rule you can use. So, 4^(5+(-2))=4^3

Review the proof of the identity cos(π − A) = −cosA.
cos(π − A)
Step 1: = cosπcosA − sinAsinπ
Step 2: = (−1)(cosA) + (sinA)(0)
Step 3: = −1cosA + (sinA)(0)
Step 4: = −cosA + 0
Step 5: = −cosA
At which step was an error made?
step 1
step 2
step 3
step 4
Answer:
error in step 1
Step-by-step explanation:
well where is does the step not make sense?
remember cos(pi) = -1 and sin(pi)=0
that means step 1 is strange... it didn't distribute properly
it should have been:
cos(pi) - cos(A)
hope that helps! ^-^
The error is made at step 1). The correct trigonometric identity is cos(π - A) = cosπcosA + sinπsinA.
What are trigonometric identities?Trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined.
cos(π - A) = cosπcosA + sinπsinA

Answer:
y = 50
Step-by-step explanation:
Firstly, let's make an equation. We know that when y is 15, x is 3. Or, in other words, y is 5 times what x is. Therefore we can use the equation, y = 5x.
Now, just plug x into the equation.
y = 5(10)
y = 50

Shantels net worth is 5,480.80 dollars.Her liabilities are 3,260.60.If she increases her assets by 10% and decreases her liabilities by 10%, what is her net work
Answer:
6681.00Step-by-step explanation:
Given
Net worth = 5480.80Liabilities = 3260.60Assets = Liabilities + Net worth
Assets = 5480.80 + 3260.60 = 8741.40
If assets increase by 10% and liabilities decrease by 10%, then net worth is:
(8741.40 + 10%) - (3260.60 - 10%) =8741.40*1.1 - 3260.60*0.9 =6681.00It takes 19.8 hours of work to plant a field of vegetables. Each person in the Fram family worked for 3.3 hours to help plant the field. How many people are in the Fram family?

Answer:
an infinite number of ways
Step-by-step explanation:
The transformation involves a series of reflections, rotations, and translations. Any reflection and translation can be described an infinite number of ways, depending on what you choose for the line of reflection (and how many reflections you choose), and how far you do each translation. Similarly, any rotation can described an infinite number of ways, depending on the amount of rotation and the chosen center point.
So, the answer to the question asked is, "You can describe the movement of the furniture an infinite number of ways."
__
One way to describe it is this:
The upper chair was translated to the right, then reflected* across the horizontal centerline. The couch was rotated 90° about the center of the room and translated upward. The coffee table was rotated -90° about its center and translated to the right.
__
* As a practical matter, a piece of furniture cannot be reflected. It can only be rotated or translated. However, the pillows in the upper chair are moved from the left arm to the right arm, so the appearance is that of a reflection. One might say the chair was rotated 180°, and the pillows were translated.
