Answer:
$41.25
Step-by-step explanation:
The original price is $25. You want to sell it for 65% more. To find this amount, we need to find 65% of 25.
Let's make an equation.
65/100 • 25 = x
Multiply.
x = 16.25
Now we know how much you want to mark it up by.
Add this to your base of $25.
25 + 16.25
= 41.25
You want to sell it for $41.25.
Hope this helps!
Answer:
<em>y = - </em><em> cos ( </em><em> x ) , y = cos ( 3x ) + 2 </em>
Step-by-step explanation:
<u><em>Image 1.</em></u>
The graph is reflection of cosine over x-axis and max is 3.5 ⇒ A = -
Period is ( 4 π ) ⇒ B =
There are no horizontal and vertical shifts ⇒ C = D = 0
<em>y = - </em><em> cos ( </em><em> x )</em>
<u><em>Image 3.</em></u>
The graph of cosine shifted 2 units up only ⇒ D = 2 , C = 0
Period of the given function is ⇒ B = 3
<em>y = cos ( 3x ) + 2</em>
<span>Answer:
Use properties of logarithm to expand the logarithmic expression as much as possible. Where possible, evaluate logarithmic expressions without using calculator.
log4(4/x) = log4(4) - log4(x) = 1 - log4(x)
------------------------------------------------------
Evaluate the expression without using a calculator.
log7 1/root:7
log7(1/sqrt(7))
= log7(1) - log7(sqrt(7))
= 0 -(1/2)log7(7)
= 0-1/2
= -1/2</span>
rational numbers are even and irrequentril numbers. like 4 or 18
