Answer:

4500π cubic feet

Step-by-step explanation:

Formula for Sphere Volume  V =  (4/3)*π*r^3

radius = (1/2)*diameter = (1/2)*30feet = 15 feet

V = (4/3)* π * (15)^3 = 4500π cubic feet

f(x) = (3/4)ˣ - 4

As x gets really negative (3/4)ˣ grows positively without bound (because it's (4/3)⁻ˣ and 4/3 > 1).

As x gets really positive (3/4)ˣ tends to zero but never quite gets there.

So (3/4)ˣ > 0 for all x

So f(x) > 0 - 4 for all x

Answer:  { y   | y > -4  }, first choice

Given the functions f(x) = 3x − 1 and g(x) = 3x + 4, which operation results in the smallest coefficient on the x term?
Vera_Pavlovna [14]
Division because if you divide the two functions together, you keep the 3 in the x term. If you add the two functions, your coefficient is 6. If you subtract, the x term is eliminated. If you multiply, you'll get 9x.
3 is smaller than 6 or 9 :)

Find the value of x in the triangle shown below.<br> a. x=21<br> b. x=42<br> c. x= 15<br> d. x=21
elena55 [62]

THEOREM:

  • <u>Pythagorean theorem</u>:— In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.

ANSWER:

By pythagorean property,

  • x² = 12² + 9²
  • x² = 144 + 81
  • x² = 225
  • x = √225
  • x = 15 units.

So, <u>Correct choice</u> - [C] 15 units.

How to I find this? I tried using Pythagorean theorem, but it didn't work
jarptica [38.1K]
The Pythagorean theorem works.

12^2+9^2=c^2
144+81=c^2
225=c^2
15=c

Therefore the perimeter is 12 + 9 + 15 = 36 in. (B)
