<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

The square pyramid with a base with edges of 6 inches and slant height of 4 inches. Hence:

Surface area = (6 * 6) + 2(6 * 4) = 84 in²

The net of the square pyramid have a base of 6 inches and the height of each triangle is 4 inches.

34. A vessel is in the the form of a hemispherical bowl mounted by a hollow cylinder The diameter

Nostrana [21]

Answer:

$V=20.85\ m^3$

Step-by-step explanation:

Given that,

The vessel is in the the form of a hemispherical bowl mounted by a hollow cylinder.

The diameter of the sphere is 3.5 m.

The height of the cylinder is 2 m

Height of the cylinder = Height of bowl− Radius of hemisphere

= 2 - (3.5/2)

= 0.25 m

The volume of the vessel is given by :

V = volume of hemispherical bowl + volume of cylinder

So,

$V=\dfrac{2}{3}\pi r^3+\pi r^2 h\\\\V=\dfrac{2}{3}\times \dfrac{22}{7}\times (\dfrac{3.5}{2})^3+\dfrac{22}{7}\times (3.5)^2\times 0.25\\\\V=20.85\ m^3$

So, the volume of the vessel is $20.85\ m^3$ .

Given that ( x + 5 ) is a factor of the function f ( x ) = x^3 + x^2 − 17x + 15 , find the zeros, and write f ( x ) in factored

mylen [45]

Answer:

The fully factored form of the function f(x) is : (x+5)(x-1)(x-3)

Step-by-step explanation:

Given function f(x)= x³+x²-17 x+15 is a third degree polynomial. Hence, it will have 3 zeros.

Also, (x+5) is the factor of given function.

⇒(x+5) divides the function f(x).

∴ (x³+x²-17 x+15) ÷ (x+5) = (x²-4 x+3)  ......(1)

Now, we will factorize x²-4 x+3 to get other zeros of the function f(X).

x²-4 x+3 ⇔ x²-3 x-x+3

⇔ x(x-3)-1(x-3) ⇔ (x-1)(x-3) ....(2)

hence, x²-4 x+3 ⇔ (x -1)(x-3)

From, equation (1),(2) the factors of f(x) = x³+x²-17 x+15 are (x -1)(x-3)(x-5)

What is the relationship between a cylinder and a sphere with the same base area and perpendicular height?

grin007 [14]

Answer:

For a sphere, the height is equal to the diameter, or two times the radius.

and because both objects have the same base area, then we can take the radius of the sphere equal to R and the radius of the base of the cylinder also equal to R.

The volume of the cylinder is:

Vc = pi*r^2*h

and here we have r = R and h = 2R

V = pi*(R^3)*2

the volume of a sphere of radius R is:

Vs = (4/3)*pi*R^3

The quotient between them is:

Vc/Vs = 2/(4/3) = 6/4 = 3/2.

This means that the volume of the cylinder is 3/2 times the volume of the sphere, always, for any value of R.
