Answer:
A=40, B=60, C=80
Step-by-step explanation:
180/7 to find what "1" would be in the ratio then multiply 20*2, 20*3, 20*4.
Answer:
The three statements on the right hand side of the screen are the correct ones
Step-by-step explanation:
To take the average of the weight of the cat in the month of April is the following:
9.8 + 9.6 + 9.7 + 9.5 + 9.4 = 48
But then divide that by the number of samples:
48/5=9.6
The mean for April is 9.6
To take the average of the weight of the cat in the month of November is the following:
9.4 + 9.3 + 9.1 + 9.2 + 9 = 46
But then divide that by the number of samples:
46/5=9.2
Then, lastly, subtract the mean from November by the mean of April:
9.6-9.2=0.4
2, 5, 8, 11, 14 is an arithmetic sequence
Answer: (B)
Explanation: If you are unsure about where to start, you could always plot some numbers down until you see a general pattern.
But a more intuitive way is to determine what happens during each transformation.
A regular y = |x| will have its vertex at the origin, because nothing is changed for a y = |x| graph. We have a ray that is reflected at the origin about the y-axis.
Now, let's explore the different transformations for an absolute value graph by taking a y = |x + h| graph.
What happens to the graph?
Well, we have shifted the graph -h units, just like a normal trigonometric, linear, or even parabolic graph. That is, we have shifted the graph h units to its negative side (to the left).
What about the y = |x| + h graph?
Well, like a parabola, we shift it h units upwards, and if h is negative, we shift it h units downwards.
So, if you understand what each transformation does, then you would be able to identify the changes in the shape's location.
