For what value of a is the volume of the tetrahedron formed by the coordinate planes and the plane (x/a) (y/10) (z/6)
kotykmax [81]

This question is incomplete, the complete question is;

For what value of a is the volume of the tetrahedron formed by the coordinate planes and the plane (x/a) + (y/10) + (z/6) = 1 equal to 10?

Answer: the value of a is 1

Step-by-step explanation:

Given that;

Volume of tetrahedron bounded by plane (x/a) + (y/10) + (z/6) = 1

and coordinate plane is; V = 1/6|abc|

(x/a) + (y/10) + (z/6) = 1

volume = 10

so

10 = 1/6 | a × 10 × 6 |

60 = a × 10 × 6

60 = 60a

a = 60 / 60

a = 1

Therefore the value of a is 1

Answer ASAP for BRAINLIEST (NO LINKS OR I REPORT)
Westkost [7]

Answer:

radius = 3 feet

Step-by-step explanation:

V = 1/3πr²h

15π = 1/3πr²·5

you can divide each side by 5π to get:

3 = r²/3

r² = 9

r = \sqrt{9} which is 3

Find the value of x. write your answer in simplest radical form
BartSMP [9]

Answer:

<h2>x = 4 \sqrt{2}</h2>

Step-by-step explanation:

To find the value of x we can use either sine or cosine

Using cosine we have

<h3>\cos(\theta)  =  \frac{adjacent}{hypotenuse}</h3>

From the question

x is the hypotenuse

4 is the adjacent

We have

<h3>\cos45=  \frac{4}{x}  \\ x \cos45 = 4 \\ x =  \frac{4}{ \cos(45) }</h3>

We have the final answer as

<h3>x = 4 \sqrt{2}</h3>

Hope this helps you
