Answer:
Volume of the cone = 
Step-by-step explanation:
Radius of the cone = 
Height of the cone = 
Volume of a cone is:

The Volume of the cone is :
Hey! Not to good at explaining this, but the correct answer is 3/5 hours, or 36 minutes.

To solve this equation , we need to write it in quadratic form

To get the equation in quadratic form we replace x^2 with u

can be written as
, Replace u for x^2
So equation becomes

Now we factor the left hand side
-16 and -1 are the two factors whose product is +16 and sum is -17
(u-16) (u-1) = 0
u -16 = 0 so u=16
u-1 =0 so u=1
WE assume u = x^2, Now we replace u with x^2
Now take square root on both sides , x= +4 and x=-4
Now take square root on both sides , x= +1 and x=-1
So zeros of the function are -4, -1, 1, 4
Answer:
From the given data, the typical appropriation is utilized rather than t distribution for testing. The thicknesses of the curve similarly influence both normal distribution and territory of t distribution. The normal distribution test and t test give a similar dismissal for the invalid theory for any tail of the test. Besides, the tests normal sampling distribution and t sampling distribution give a similar dismissal to null hypothesis.
Along these lines, the outcomes got by utilizing normal distribution and t distribution are distinguished as same and for each situation, the tail thickness doesn't influence the event of the basic qualities.
Step-by-step explanation:
Length of base = 20cm
We will take the base as "b"
Area of a triangle = 1/2 x base x height
So the total area = 360 square feet
360 square feet = 1/2 x b x 36
360 = 36b /2
360 = 18b
b = 360/18
b = 20
So, Length of base = 20 cm
Let's check:
1/2 x 20 x 36 = 360
Which is the correct area!
Hope this helps!
