Ok so first you do z to the second power which is 81. Then, you do 9 times z which is also 81. Lastly you add 81+81+10 to get 172. Hope I could help!

Write an inequality for the given statement: The sum of –18 and a number is more than 22.

tia_tia [17]

Let that number be 'x'

So the inequality will be
- 18 + x > 22

or x - 18 > 22

Hope This Helps You!

Answer:

Option (4).

Step-by-step explanation:

Outer diameter of the hollow metallic ball = 10 centimeters

Outer radius of this ball = $\frac{10}{2}$ = 5 cm

Volume of the outer ball $V_{1}$ = $\frac{4}{3}\pi (r)^3$

= $\frac{4}{3}\pi (5)^3$

Inner radius of the hollow metallic ball = (5 - 1) = 4 cm

Volume of the inner hollow ball $V_{2}$ = $\frac{4}{3}\pi (4)^3$

Volume of the metal used in the metallic ball = $V_{1}-V_{2}$

= $\frac{4}{3}\pi (5)^3-\frac{4}{3}\pi (4)^{3}$

= $\frac{4}{3}\pi [(5)^3-(4)^3]$

Therefore, expression given in option (4) will be used to measure the volume of the hollow metallic ball.

The function g(x) is defined as g(x) = 6x2 + 23x – 4. When does g(x) = 0?

MrMuchimi

6x^2 + 23x - 4 = 0
factorising:-

(6x - 1)(x + 4 ) = 0

x = 1/6 , - 4
