Answer: (-1, 4) is the vertex of the parabola.
To find the vertex when you are given the equation in vertex form, all you have to do is look at the letters k and h. They will tell you what the vertex is.
It is always (h, k)
There is only one trick in this problem. You have to change "(x + 1)" to "(x - (-1))" since the format of the equation requires "(x - h)".
This makes the h value -1 instead of 1.
4 times 1 equals 4 then do 81 minus 4 which equals 77 so 77 is your answer
Answer:
the graph is in link
Step-by-step explanation:
y ..... means full line and shading above the line
Y< ......means doted line and shading below the line
A) solution is overlapping shaded part
B) (10,5)
plug in point in inequalities and check if it's true; if it's true you showed that solution is correct
1. 5-1/2*10 + 2 1/2
5 -5 + 2 1/2
5 -2 1/2 TRUE
2. 51/5*10 + 6
5< 2 + 6
5< 8 TRUE
<h2>
Answer:</h2>
The description that match the type of measure is:
Measure of center-- She found the middle value after arranging all the values from least to greatest.
Measure of variation of this data -- She found the mean and then found the average deviation of the weights from the mean.
<h2>
Step-by-step explanation:</h2>
As we know that the median of the data is the central tendency of the data and exist in the middle of the data.
Hence, the measure for the center of data is: Median.
and it is calculated by arranging the data in ascending or descending order and taking the middle value.
Also, we know that MAD of data or mean absolute deviation is used to tell the variation in a data set.
and the steps to calculate it is:
- Find the absolute deviation of data points from the mean.
- Calculate the mean of these absolute deviation.
Answer:
16, 100
Step-by-step explanation:
A perfect square is a number that can be achieved by multiplying a number by itself.
Example: 100 = 10 x 10, so it is a perfect square
2 is not a perfect square because it has no factors that can be multiplied with each other to equal 2. An easy way to check is to use the square root function on your calculator.
If the result is a whole number then it's a perfect square.
