Answer:
r = 4.908
Step-by-step explanation:
V = 885
height (given in the picture) = 11.7
V = 
h
V = (3.14)(
)(h)
885 = (3.14)()(11.7)
885/3.14/11.7 =
Take the square root and you get 4.908.
Answer:
yes, it is.
Step-by-step explanation:
Answer:
60
Step-by-step explanation:
So they are showing you a chart in which the column y is determined by the column x, so you divide y/x in any of the rows so that you get the relation.
100/4=25 (which is the same for every row)
It works pretty much the same for the graph, but the relation is different.
Now instead of a chart you have to figure out the values of x and y by looking at the points that make up the line. For example we have a point that is in the coordinate (2, 60), and that represents that the x value is 2 and its correspondent y is 60. And to find the relation we do it as in the first step but now with 2 and 60.
60/2=30 (which is the same for every point)
Finally we just calculate the value of y both in the graph and the chart when x=12
So for the chart: 12*25= 300
And for the graph: 12*30= 360
The difference between those two is 60.
To find the slope you rise before you run and if you can't rise then you go downwards so it would be down -3 over positive 2
Y-y1= m(x-x1)
y-3= -4(x-(-2))
y-3= -4(x+2)
y-3= -4x-8
y= -4x-5
Final answer: A
