Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To find the answer of this we will have to this we will have to add each of the answers together...

To find Volume of a Cylinder: π(r^2)h

To find Volume of a Cone: π(r^2)(h/3)

Givens for a Cylinder: r= 2, h=3

Givens for both Cones: r=2, h=3

Cylinder:

V= π(r^2)h

V= π(2^2)3

V= π(4)3

V= 12π

Volume of both Cones added together:

V= (π(r^2)(h/3)) * 2

V= (π(2^2)(3/3)) * 2

V= (π(4)(1)) * 2

V= (π4) * 2

V= 8π

Volume for Whole Shape:

12π + 8π = 20π cm^3

So...

The answer is: C.) 20π cm^3

1.What is the shape of the graph of any quadratic function?

likoan [24]

Answer:

Inverted parabola

Two complex solution

Step-by-step explanation:

any quadratic equation can be expressed in terms of ax^2 + bx + c = 0

It has two solutions which can be found using formula $X =( -b + \sqrt{b^2 -4ac} )/2a \\or \ ( -b - \sqrt{b^2 -4ac} )/2a$

We know that for any value inside the square root function

if it is positive its solution will be real number

for example $\sqrt{9}$ we can have two real solution -3 and 3

if it is negative its solution will be complex number

for example $\sqrt{-9}$ we can have two complex solution

expressed in term of a + ib or a - ib

------------------------------------------------------------------------------------------

Given in the problem

we have ax^2 - bx + c

so its solution will be

$X =( -(-b) + \sqrt{b^2 -4ac} )/2a \\or \ ( -(-b) - \sqrt{b^2 -4ac} )/2a\\\\X =( b + \sqrt{b^2 -4ac} )/2a \\or \ ( b - \sqrt{b^2 -4ac} )/2a\\$

Since in this expression it is given in problem statement that b^2 - 4ac < 0 which will be a negative number and for negative number, its square root is complex number.

also X has two values as given above it will have two solution

hence it will have two complex solution based on above discussion.

Also for any quadratic equation shape of its curve if plotted on coordinate plane is parabolic.

If it has complex solution then curve of such expression will not pass through X axis

There are 12 girls and 8 boys in Ms. Sander’s class. Each day, she randomly asks one student to take attendance. In 180 school d

Assoli18 [71]

If there are 30 students then each student would probably get called up 6 times. I did this by dividing 180 by 30 that got me so each student will go up at least 6 times if there are 30 students

Determine how long it will take an object to rotate through 20.0 revolutions at an angular velocity of 2.8 radians per second. U

Andreyy89

The conversion factor between radians and revolution as measures of angle is 2π rad is equal to 1 revolution. Converting the given angular velocity to rev/s,
(2.8 rad) x (1 rev / 6.28 rad) = 70/157 revolution per second
Dividing the given angle, 20 rev by the velocity,
(20 rev) / (70/157 rev/s) = 44 6/7 s
Thus, the answer is approximately 44.9 seconds.
