Answer:
Step-by-step explanation: Graph the two points on your paper. Find the point where they cross(x,y). The y is your answer
Answer:
Here, Diameter of the whole tube = 10 m
Diameter of the inner tube= 10mm - 2 mm= 8mm
Now,
Area of the shaded region =1/4 ×πd^2
=1/4×3.14×8^2
=50.24 mm^2
Answer:
The measure is 145
Step-by-step explanation:
Answer: Add the equations to eliminate k
Step-by-step explanation:
Adding the equations, you get 2b=18, which you can solve for b. Afterward, you can substitute this value of b back into either equation to solve for k.
Hello!
We are trying to describe the behavior of the graph given in the question.
To help us understand how to solve this question, we would need to understand <u>concavity.</u>
There are two types of concavity:
- Concave <em>up</em>
- Concave <em>down</em>
When a graph is concave up, the slope of the line would look like a "U".
When a graph is concave down, the slope of the line would look like a "U" that is flipped upside down.
In this case, we can see that the graph is concave down.
We can tell that the <em>slope</em> is negative due to the fact that the slope is going <u>down,</u> which results in the graph having a negative slope.
We can also tell that the graph is decreasing due to the fact that the line is doing downward.
Answer:
C). negative and decreasing
