I need help on finding the height of a triangular pyramidif there’s no work, I don’t get credit

I will give Brainliest

Answers

Answer:

20 in

Step-by-step explanation:

The formula for the volume of a triangular pyramid is V=1/3 x B x H, in which B is the area of the base and H is the height. You're given the volume and area of the base so you can just plug that into the formula. You will get 120 = 1/3 x 18 x H. You can multiply the 1/3 and 18 so you will get 120 = 6H. In this case, you are solving for H so you need to isolate the variable. You can do this by dividing both sides by 6. You will end up eith 20 = H.

If the garden is to be 1250 square feet, and the fence along the driveway costs $6 per foot while on the other three sides it costs only $2 per foot, find the dimensions that will minimize the cost.

Answers

So, the minimum cost is $400.

Area of the rectangle:

The area of a rectangle is the region occupied by a rectangle within its four sides or boundaries.

And the formula is,

$A=l* b$

Given that,

Area of the garden=1250 square feet.

Let, the length be $x$ and the breadth be $y$ then,

$xy=1250...(1)$

The total cost of the fence is,

$C(x,y)=6x+2x+4y\nC(x,y)=8x+4y\nC(x)=8x+4((1250)/(x) )\n$

Now, differentiating the obtained equation we get,

$C'(x)=8-(4* 1250)/(x^2) =0\nx^2=625\nx=25\ny=50$

Therefore the length is 25 ft

And breadth is 50ft

Now, calculating the minimum cost,

$8(25)+4(50)=50\n=400$

Answer:

Dimensions of rectangular garden:

x = 25 feet ( sides along the driveway)

y = 50 feet

Step-by-step explanation:

Rectangular area is:

A(r) = x*y (1)

if we call x one the driveway side the cost of that side will be

6*x

The cost of the other side parallel to driveway side is 2*x and cost of the others two sides are 4*y

Total costs: C = 6*x + 2*x * 4*y (2)

From equation (1)

A(r) = 1250 = x*y ⇒⇒ y = 1250/ x

Plugging that value in equation (2) we get costs as a function of x

that is:

C(x) = 6*x + 2*x + 4* 1250/x

Taking derivatives on both sides of the equation

C´(x) = 6 + 2 - 5000/x²

C´(x) = 8 - 5000 /x²

C´(x) = 0 ⇒ 8 - 5000 /x² = 0

8*x² -5000 = 0

x² = 5000/8

x² = 625

x = 25 feet

and y = 1250/ 25

y = 50 ft

C(min) = 50*2*2 + 6*25 + 2*25

C(min) = 200 + 200

C(min) = 400 $

what is f'(3) of this equation?

Answers

Answer:

$3 + (1)/(2√(3) ) + \frac{1}{5\sqrt[5]{81} }$

Step-by-step explanation:

Just to make it easier to see, $√(x) = x^{(1)/(2) }$ and $\sqrt[5]{x} = x^{(1)/(5) }$ This way we could more easily use the power rule of derivatives.

So if f(x) = $x^(2) +x^{(1)/(2) } +x^{(1)/(5) }$ then f'(x) will be as follows.

f'(x) = $x^(1) +(1)/(2) x^{-(1)/(2) } +(1)/(5) x^{-(4)/(5) } = x +\frac{1}{2x^{(1)/(2) }} +\frac{1}{ 5x^{(4)/(5) }} = x +(1)/(2√(x)) +\frac{1}{ 5\sqrt[5]{x^4} }$

to find f'(3) just plug 3 into f'(x) so $3 + (1)/(2√(3) ) + \frac{1}{5\sqrt[5]{81} }$
