Answer:
.
Step-by-step explanation:
3x - y = 17 .......A
10 × [x/5 + y/2] = 10 × 0
2x + 5y = 0 .......B
......A× 5 both 2 sides of equation
15x - 5y = 85 .....C
......B + ........C
2x + 15x = 0 + 85
17x = 85
x = 85/17
x = 5
put x value in ........A or .......B or ......C
you will receive y = -2
Answer:
Step-by-step explanation:
Let represent the edge of the tank with x and the radius of the first sphere with x/2;
The amount of the water = Volume of the tank - Volume of the sphere
=
on the second cube ; the radius of the sphere = ;
Also the number of sphere here is = 8
The amount of water =
For the third figure ; the radius of the sphere is =
Also the number of sphere here is = 64
The amount of water =
=
In the fourth tank ; 512 sphere illustrates that in a single row; that more than one 8 sphere is present i.e 8³ = 512
then the radius will be =
The amount of water =
=
This implies that alll the three cube shaped tanks are identical and hold equal amount of water.

Answer:
, and , .
Step-by-step explanation:
A polynomial is an algebraic function of the form:
(1)
Where:
- i-th Coefficient.
- i-th Power.
- Grade of the polynomial.
- Dependent variable.
Mathematically speaking, polynomials are unbounded functions, and from graphic we notice that polynomial is of order 3 due to the fact that function pass through the x axis three times, where each point is a root of the polynomial.
Then, we may conclude that:
(i)
(ii)
Then, the right answer is: , and , .
