Answer:
<u>first graph:</u>
function.
Not one-one
onto
<u>Second graph:</u>
Function
one-one
not onto.
Step-by-step explanation:
We know that a graph is a function if any vertical line parallel to the y-axis should intersect the curve exactly once.
A graph is one-one if any horizontal line parallel to the x-axis or domain should intersect the curve atmost once.
and it is onto if any horizontal line parallel to the domain should intersect the curve atleast once.
Hence, from the <u>first graph:</u>
if we draw a vertical line parallel to the y-axis then it will intersect the graph exactly once. Hence, the graph is a function.
But it is not one-one since any horizontal line parallel to the domain will intersect the curve more than once.
But it is onto, since any horizontal line parallel to the domain will intersect the curve atleast once.
<u>Second graph</u>
It is a function since any vertical line parallel to the co-domain will intersect the curve exactly once.
It is not one-one since any horizontal line parallel to the x-axis does not intersect the graph atmost once.
It is not onto, since any horizontal line parallel to the domain will not intersect the curve atleast once.
Answer:
Step-by-step explanation:
<u>Given the sequence </u>
<u>We see it is an AP with</u>
- The first term a = 13
- Common difference d = 13 ( as 26 - 13 = 39 - 26 = 13)
<u>The 12th term is:</u>
- a₁₂ = a + 11d = 13 + 11*13 = 156
Volume of cone is given by formula
-------------------------------------------(1)
We are already given r =2, so we need to find h and then we can find volume
So missing meausre is height here ------------------------------------------------------------------------------
To find h we will use lateral area =
given
Formula for lateral area of cone is 
so we have
Now plug r as 2 in this equation

Now solve for h as shown and get h by itself








----------------------------------------------------(2)
Now plug 2 in r place and
in h place in volume formula given in (1)

![V = \frac{\pi (2)^{2}4\sqrt{2}}{3} [/tex][tex] V = \frac{\pi (4)4\sqrt{2}}{3}](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cfrac%7B%5Cpi%20%282%29%5E%7B2%7D4%5Csqrt%7B2%7D%7D%7B3%7D%20%20%20%20%20%5B%2Ftex%3C%2Fp%3E%3Cp%3E%5D%5Btex%5D%20V%20%3D%20%5Cfrac%7B%5Cpi%20%284%294%5Csqrt%7B2%7D%7D%7B3%7D%20%20%20%20%20)

so choice (1) is right answer

The volume of a cube by definition is:
V = L ^ 3
Where:
L: side.
We have then that the volume of a cube is:
V = (1/3) ^ 3
V = 1/27
Then, the prism volume is:
Vtotal = 3996 * V
Vtotal = 3996 * (1/27)
Vtotal 148 inches ^ 3
Answer:
the volume of the prism is:
Vtotal 148 inches ^ 3
