Ng ne Volume of a Cone

Mathematics
1 answer:
AnnyKZ [126]3 years ago
6 0
Answer: height = 6, radius = 8, Volume = 401.92

Explanation:
Height = 6 given

Find radius:

Use Pythagorean’s theorem to find the side of the right triangle:

a^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 10^2 - 6^2
b^2 = 100-36
b^2 = 64
b = 8

And since length b is also the radius of the circle then radius = 8

Find volume:

V = pi x r^2 x h/3

V = 3.14 x 8^2 x 6/3

V = 3.14 x 64 x 2

V = 401.92

How to Factor the Trinomial x^2 - x + 1 using the box method?<br><br><img src="https://tex.z-dn.net/?f=x%5E2%20-%20x%20%2B%201"
IRINA_888 [86]

Answer:

x = 1+√3 i/2 and x = 1-√3 i/2

Step-by-step explanation:

Given the expression x^2 - x+ 1, we are to factorize the expression as shown;

x^2 - x+ 1,

using the general formula

x = -(-1)±√1²-4(1)/2(1)

x = 1±√1-4/2

x= 1±√-3/2

x = 1±√3 i/2

Hence the required value of x are x = 1+√3 i/2 and x = 1-√3 i/2

If F(x) = 4%-3, which of the following is the inverse of F(x)?
Brums [2.3K]

I assume you meant to type x for %.

If not, basically back-substitute at the end of the solution.

F(x) = 4x - 3

Let y = F(x)

y = 4x - 3

x = 4y - 3

x - 3 = 4y

(x - 3)/4 = y

Let y = F^(-1)x

F^(-1)x = (x - 3)/4

If you want % in your answer, just replace x for % in your answer.

What is the value of x for 7x - 12 y = 180 / 7x = 84
katrin2010 [14]

eq^2: 7x=84 divide 84 by 7 which is 12.

therefore x is equal to 12. Then

1) take that 12 you got in equation 2 and substitute in equation 1 which is:

7x-12y=180

7(12)-12y=180

84 -12y=180

-12y=180-84

-12y=96 ............divide both sides with -12

-y=8 (×-1) both sides

y= -8

therefore 7(12)-12(-8)=180
