Answer:
The original equation must have been:
Step-by-step explanation:
A quadratic equation is in the form of :
And it is solved in the form of :
and
Now the given equation is :
We can see that here;
a = 7
b = -5
c = -2
So, the original equation must have been:
Answer:
A
Explanation:
For functions to be inverse, it must be true that f( g(x) ) = x and g( f(x) ) = x.
But for F( G(x) ), we have √( G(x) - 3 ) + 8
= √( (x+8)² - 3 - 3 ) + 8
= √( (x+8)² - 6 ) + 8
This -6 part should be cancelled out for functions to work out but we cannot do that, therefore F(x) and G(x) are not inverse.

Answer:
12 cm³
Step-by-step explanation:
the volume of the sphere = 4/3 πr³
the volume of the cylinder (h=2r)= πr².2r
= 2πr³
the volume ratio of S : C =
4/3 πr³ : 2 πr³
= 4/3 : 2
= 4 : 6
= 2 : 3
so, the volume of the Sphere =
2/3 × 18 = 12 cm³
All you'd have to do is multiply 20 cm2 by 5 cm because volume is cm3, so if the base is already giving you cm2, you'll need the last measure which is height.
The answer would be 100 cm3
