Answer:</h2>
<h2>
Step-by-step explanation:</h2>
The graphs of can be obtained from the graph of the cosine function using the reciprocal identity, so:
But in this problem, the graph stands for the function:
Because the period is now 4π as indicated and for in the figure and this can be proven as follows:
Also, as indicated in the figure and this can be proven as:
Start by distributing through the parentheses on
each side of the equation to get 3x - 12 = 2x - 12.
Now move your x's to the left by subtracting
2x from both sides to get x - 12 = - 12.
Now move your numbers to the right by
adding 12 to both sides to get x = 0.
So, the solution to this equation is <em>x = 0</em>.
Answer: A
Step-by-step explanation: it has to be A sorry if i'm wrong
Answer:
Step-by-step explanation:
18 min = 0.3 h
Car 1 started 0.3 h before Car 2.
Let t = time of Car 2. Then
t + 0.3 = time of Car 1
Distance = speed × time, and both cars travel the same distance. Then
Check:
OK.
Answer:
72
Step-by-step explanation:
bacause the equation of area of square is a^2 and 12×12=144 so each side is 12 feet and the height is 6 making it 12×6 so 72 square feet
