<span>We know that sin^2(x) = 1 - cos^2(x), so
2 - 2 cos^2(x) = 2 + cos(x)
cos(x) + 2 cos^2(x) = 0
One immediate possibility is that cos(x) = 0, in which case x = Pi/2 or
3pi/4. If cos(x) is not zero, then divide both sides by cos(x) to obtain
cos(x) = -1/2
which gives x = 2Pi/3 and x = 4Pi/3.
So your solutions are
Pi/2, 3Pi/4, 2Pi/3, and 4Pi/3
Hope this helps :D</span>
The rate of change in a linear equation of the form:
is m. This means that for carpet company A the rate of change is 1.35 and for company B the rate of change is 2.05.
Therefore, company B has the greatest rate of change.
The rate of change is the same as the slope in a line. This means that the greater the rate of change is the faster the line will grow. This can be seen in the following graph:
where the red line is the graph for company A and the blue line is the graph for company B.
Answer:
A. The x-coordinate of the vertex is greater than the y-coordinate. The function f(x) = x2 + 10x - 3 written in vertex form is f(x) = (x + 5)2 - 28.
Step-by-step explanation:
The number of salads Ishaan and his friends can afford is 6 salads.
<h3>What are Word Problems?</h3>
Word Problems in mathematics involve crucial understanding and the use of variables and arithmetic operations to solve real-life cases.
From the given information;
- The total amount with Ishaan and his friends = $40
- If they decided to spend the money on salad(x) and one salad(x) cost = $6
Thus, the number of salads they can purchase is:
x = 6 salads remaining $4
Therefore, we can conclude that the number of salads they can purchase with $40 is 6 salads with a remaining amount of $4.
