Answer:
35
Step-by-step explanation:
For the function f ( x ) = x² we have the new function f 1 ( x ) = 1/2 x².f ( x ) = a · x²- If |a| < 1 the graph is compressed vertically by a factor of a.- If |a| > 1 the graph is stretched vertically by a factor of a.Here: a = 1/2 < 1
Answer:C. The graph will be compressed vertically.
Answer:
220!
Step-by-step explanation:
You multiply 60 & 72 = 4320, then you divide 4320 by 8 = 540, and you take 320 from 520 and you should get 220...
The equation to your question would be P =10(c)+20. meaning 10 pencils in each box multiplied by the number of boxes (c) plus the 20 pencils the teacher gives her will equal the number of pencils (P) she has altogether. (C stands for the number of boxes and P stands for pencils)
so lets say she has 3 boxes. well, c stands for boxes soooo...... all you have to do is plug in 3 were c is. giving you this equation P = 10(3)+20. then all you have to do is solve. P = 10(3)+20
10 times 3 = 30 so P = 30+20
then add 30 and 20 P = 50 she has 50 pencils altogether
(remember this is just an example, 50 pencils is NOT the answer to your question. but you can use the equation i gave you to find your own answer!) :) Hope this helps!!
<span>Pearson's correlation coefficient 'r' measures the degree to which two variables are correlated. The value is between -1 and 1. Negative values correspond to negative correlation (as one variable increases, the other variable decreases) whereas positive values correspond to positive correlation. The larger the absolute value of r, the closer a correlation graph resembles a set of points on the same line.
Therefore, if two variables are completely correlated, the correlation value is 1 or -1, depending on whether the correlation is positive or negative.</span>
