A caisson has a radius of 2ft and a depth of 5ft . how many cubic feet are in the caisson

1 answer:

5 0

Measure the length in feet and the width in feet with the tape measure, then measure the depth in feet with a dip stick if your pond is a square or rectangle.
2
Multiply the length by the width by the depth to get the volume in cubic feet. For example, if your pond is 16 feet long, 8 feet wide and 4 feet deep, multiply 16 by 8 by 4 to get 512 cubic feet.
3
Convert cubic feet to gallons by multiplying the cubic feet by 7.48. In this example, multiply 512 cubic feet by 7.48 to get 3,830 gallons of water in a rectangular pond.

Plz help i need to finish this asap so i can graduate

Sloan [31]

F(x) = x^2 + 3x + 2
if g(x) is the reflection of f(x) across the x - axis then
g(x) = -f(x)
g(x) = - (x^2 + 3x + 2)
g(x) = - x^2 - 3x - 2

Prove that the altitude to the base of an isosceles triangle is also the median to the base

QveST [7]

If altitude drawn from vertex A is also the median, the triangle is isosceles such that AB = AC and BC is the base. Hence this altitude is also the angle bisector. – If median drawn from vertex A is also the angle bisector, the triangle is isosceles such that AB = AC and BC is the base.

Please help i’ll mark u brainliest

Likurg_2 [28]

Answer:

there is a lot of solutions here is some guidance. so if there are more then 4 and less then 10 then every solution should equal 5, 6, 7,8, and 9. also it says the number of pencils is more then the number of pens so for example if it was to equal 9 i would put 5 + 4 . 5 is the number of pencils, 4 is the number of pens or i could put 6 + 3 so any numbers that equal to what i said; 5, 6, 7,8, and 9. good luck!

g in october 2012, apple introduced a much smaller version of the apple ipad, known as the ipad mini. weighing less than 11 ounc

atroni [7]

Using the concepts of probability, we got that 0.4286 is the probability that the battery life for an iPad Mini will be 10 hours or less which is about 42.86%.

From the given information;

Let X represent the continuous random variable with uniform distribution U (A, B) . Therefore the probability density function can now be determined as :

$f_X(x)$ = $\frac{1}{B-A}$ where A<x<B

where A and B are the two parameters of the uniform distribution

From the question;

Assume that battery life of the iPad Mini is uniformly distributed between 8.5 and 12 hours

So; Let A = 8,5 and B = 12

Therefore; the mathematical expression for the probability density function of battery life is :

$f_X(x)$ = [1 / (12-8.5)]8.5<x<12

$f_X(x)=$ (1/3.5)8.5<x<12

The probability that the battery life for an iPad Mini will be 10 hours or less can be calculated as:

F(x) = P(X ≤x)

F(10)= $(x-A)/(B-A)$

F(10)=(10-8.5)/(12-8.5)

F(10)=1.5/3.5

F(10)=0.4286

Hence, the probability that the battery life for an iPad Mini will be 10 hours or less is 0.4286

(Complete question)

In October of 2012, Apple introduced a much smaller variant of the Apple iPad, known at the iPad Mini. Weighing less than 11 ounces, it was about 50% lighter than the standard iPad. Battery tests for the iPad Mini showed a mean life of 10.25 hours (The Wall Street Journal, October 31, 2012). Assume that battery life of the iPad Mini is uniformly distributed between 8.5 and 12 hours. What is the probability that the battery life for an iPad Mini will be 10 hours or less (to 4 decimals)?
