Answer:

The answer is 792.

Step-by-step explanation:

I got the answer by first imagining how the 3d shape looks ike. Since one of the sqaure base length is 11 I found the base surface area by doing 11 times 11.My answer was 132. The since one of the slant length of the pyramid's triangle is 15, I did 11 times 15, my answer was 165. There are four triangles in the pyramid so I did 165 times 4, my answer was 660.

All the triangle surface area is 660 plus the sqaure surface are which is 132, that gave me my answer 792.

Let x²y +ay² = b be an Implicitly defined function, where a and b are fixed Constants; find dy/dx
geniusboy [140]

The value of the differential with respect to x is -xy/x²+ay

<h3>Implicit differentiation</h3>

Given the following function

x²y +ay² = b

We are to differentiate implicitly with respect to x

x²dy/dx + 2xy + 2aydy/dx = 0

(2x²+2ay)dy/dx = -2xy
dy/dx = -xy/x²+ay

Hence the value of the differential with respect to x is -xy/x²+ay

Kamila [148]

Answer:

<h2>Less than 0.84</h2>

Step-by-step explanation:

  1. Convert all numbers to decimals
  • 85% --> 0.85
  • 0.88 --> 0.88
  • 21/25 --> 0.84

Since these are the top three, the rest of the competitors are less than 0.84.

The volume of a sphere is 36π cubic feet. What is the radius of the sphere? (V = 4 3 πr3)
MrRa [10]

radius = 3 feet

rearrange the formula making r the subject

\frac{4}{3} πr³ = V ( multiply both sides by 3 to eliminate fraction )

4πr³ = 3V ( divide both sides by 4π )

r³ = \frac{3V}{4\pi } = ( 3 × 36π ) / 4π = 3 × 9 = 27

take the cube root of both sides

r = \sqrt[3]{27} = 3
