When you have the same base buy different exponents, subtract the exponents:
5-3=2
4.5^2
Answer:
The statement is true.
Step-by-step explanation:
Given : Reflecting the graph of y = sin x across the y-axis is the same as reflecting it across the x-axis.
To find : Is this statement true or false?
Solution:
Rules of reflection :
Along across y-axis if we have a point
So, y=sinx
The reflection across y-axis→ .......[1]
Along across x-axis if we have a point
so, y=sinx
The reflection across x-axis → .....[2]
Hence, [1] and [2] both of them are equal
Therefore, the statement is true.
Answer:
40% * 71 = Markup price
40% of 71 is 28.4, so i added the two together and got 99.4
so...
$28.4 + $71 = $99.40
Answer:
11/40 + 1/4 + 1/20
Step-by-step explanation:
Draw a Venn diagram: (as shown)
Consumer Ed. : 22-4=18
French : 20-4=16
Neither : 80-18-16-4=42
Using probability notation where P(A) means probability of event A occurring.
P(Consumer Ed.) = 22/80
P(French) = 20/80
P(Both) = 4/80
<em>'or ' </em>in the question means you add.
=> 22/80 + 20/80 + 4/80
=> 11/40 + 1/4 + 1/20
