Find the measurement of either the leg or the hypotenuse: A = B = 21 C = 35

Varvara68 [4.7K]

Answer: x = 40.81 or 41

Step-by-step explanation:

A = B = 21

C = 35

Hypotenuse = x

Calculating Hypotenuse:

21^2 + 35^2 = x^2

=> 441 + 1225 = x^2

=> x^2 = 1666

=> x = 40.81 or 41

Max p=3x+2y subject to 5x+y<16 2x+3y<22 x>0 y>0

garri49 [273]

Answer:For all the corner points, the maximum is at point (1, 3)

From the graph of the constraints, the corner points of the feasibility region are (0, 0), (0, 10/3), (1, 3), (2, 0)

For (0, 0): p = 0 + 2(0) = 0

For (0, 10/3): p = 0 + 2(10/3) = 20/3 = 6.67

For (1, 3): p = 1 + 2(3) = 1 + 6 = 7

For (2, 0): p = 2 + 2(0) = 2

Therefore, solution = (1, 3)

3. The volume V of a cone is given by the

hammer [34]

Answer:

Step-by-step explanation:

The most appropriate choice of volume of a cone is given by-

$h=\frac{3v}{\pi r^{2} }$

What is volume of a cone?

The volume of a cone is the amount of space occupied by the cone.

Volume of a cone is given by the formula

$V=\frac{1}{3} \pi r^{2} h$

Where, r is the radius of cone and h is the height of the cone.

Here,

$V=\frac{1}{3} \pi r^{2} h\\3V=\pi r^2h\\h=\frac{3V}{\pi r^2}$
