Use Socratic it will give you the answer
Working out:
2 3/4 ー 1 1/4 = 1 2/4 = 1 1/2
Answer:
He needs to run 1 1/2 more miles.
Answer:
Step-by-step explanation:
If a population of insects grows exponentially, then the equation represents this situation, where x is the number of weeks and y is the population.
When x=0, y=10, then
When x=1, y=30, then
When x=2, y=45, then
The function that represents situation is
Now find y when x=11:
The equation 2cos^2(x) - 1 = 0 we manupulate by adding 1 to both sides and then dividing both sides by 2.
2cos^2(x) - 1 = 0
2cos^2(x) = 1
<span> cos^2(x) = 1/2
</span> cos(x) = ±√1/2
<span> cos(x) = ±√(2)/2 </span>
The answers to your question are <span>A. 3pi/4, B. 15pi/4, and D. </span>-7pi/4 as they all are angles with a reference angle of pi/4. They will have a cosine ratio of <span>√(2)/2 or </span><span><span>-</span>√(2)/2</span>
The right answer for the question that is being asked and shown above is that: "<span>C. 4sqrt. 3 - 4sqrt. 3."
</span>
The right answer for the question that is being asked and shown above is that: "<span>B. 3 sqrt. 10 -3 sqrt. 10." </span>
