Answer:
(1/10)x = 11/12
x=11/12×10/1=110/12=55/6or9 1/6
I normally use a graphing calculator, but if you need to graph by hand I normally make a table with the x-values of -5 to 5 and plug in those range of x-values to graph the dots on the plot.
For example, if the function was , I would want to start with a table, and plug in my x-values to given formula as I go through each x.
x = -5 then y =
x = -4 then y =
x = -3 then y =
x = -2 then y =
x = -1 then y =
x = 0 then y = 0
x = 1 then y =
x = 2 then y =
x = 3 then y =
x = 4 then y =
x = 5 then y =
Of course you don't have to use for the x-values -5 to 5 if it's too long. At least 5 points should be made on the graph to improve accuracy. Other things like max, min, y-intercept, slope, x-intercept, etc all matter when graphing but if you were to just look at how to draw the basic functions first and how they look like, everything else will come naturally.
Now that the table of x and y values are made, you just need to plot this on a graph and connect the dots. The rest of the graph can be sketched to be an estimate of what the other values of x would possibly be equal to. As long as the bottom points of is complete and accurate the rest is drawn as close as you can make it, if that makes sense...
Hope that helps!
Answer:
Step-by-step explanation:
Prove this:
volume of cylinder = volume of cone + volume of sphere
πr²h = (1/3)πr²h + (4/3)πr³
Note that the factor πr² is common to all three of these formulas. Factoring out this πr², we get:
h = h/3 + (4/3)r
or: 3h/3 = h/3 + 4r/3
or: 3h = h + 4r
or: 2h = 4r
or: h = 2r
Note that 2r is the diameter of the sphere, and that this diameter is twice the radius. Thus, in view of the givens. this equation h = 2r is correct.
Thus, the volume of the cylinder is equal to the volume of the cone PLUS the volume of the sphere.
Answer:
B. 294 divided by 21 = 14. she paid 14 for each t shirt
Answer:
Step-by-step explanation:
So we have the equation:
And we want to find a such that x = 7 is a possible solution.
To do so, substitute 7 for x. Thus:
Multiply the left and distribute the right:
Subtract:
Subtract 14 from both sides:
Divide by -2: "
So, the value of a is 3.
And our equation would be:
And we're done!
