The expression of the ratio is 150:3
Using Sin^2 and Cos^2 identities,
= Cos^2(2A) + 4[(1/2)(1-Cos(2A)][(1/2)(1+Cos(2A)] = 1
= Cos^2(2A) + 1 -Cos^2(2A) = 1
0 = 0
There is nothing to solve for as it is an identity of sorts.
Answer:
D) 225
Step-by-step explanation:
Given in chart. The box at column "Milk Sold" and row "Friday" has the number 225 in it. Cumulative milk sold refers to the total number of milk sold through the entire chart (from top to bottom) so far. The question is asking for how many milks were sold on Friday specifically, so we want the "Milk Sold" column.
Answer:
A simple expression is 
= 4
Step-by-step explanation:
Surds are irrational numbers expressed with respect to a square root. There are some basic rules required when dealing with surd.
Integers are numbers that do not have a decimal or fractional part i.e whole numbers. So, a simple expression that can be written as k square root 3 where k is an integer is .
So that,
= 
= 4
Answer:
Step-by-step explanation:
<u>Let's calculate time for building and testing:</u>
- 5*4 + 15*6 = 110 < 120, yes
- 5*4 + 15*4 = 80 < 100, yes
<u>In general you would need to solve inequalities below:</u>
and
<u>Simplified, we have the system:</u>
