The multiplication of the expression (x² + 3x + 2) (2x² + 3x + 1) is 2x⁴ + 9x³ + 14x² + 9x + 2

<h3>Multiplication</h3>

(x² + 3x + 2) (2x² + 3x + 1)

= 2x⁴ + 3x³ + x² + 6x³ + 9x² + 3x + 4x² + 6x + 2

  • collect like terms

= 2x⁴ + 3x³ + 6x³ + x² + 9x² + 4x² + 3x + 6x + 2

= 2x⁴ + 9x³ + 14x² + 9x + 2

Given:

The function is

f(x)=4x+9

Domain = {-4, -2, 0, 2}

To find:

The range of the given function for the given domain.

Solution:

We know that domain is the set of input values and range is the set  of output values.

We have, f(x)=4x+9 and domain = {-4, -2, 0, 2}.

Putting x=-4 in the given function, we get

f(-4)=4(-4)+9

f(-4)=-16+9

f(-4)=-7

Putting x=-2 in the given function, we get

f(-2)=4(-2)+9

f(-2)=-8+9

f(-2)=1

Putting x=0 in the given function, we get

f(0)=4(0)+9

f(0)=0+9

f(0)=9

Putting x=2 in the given function, we get

f(2)=4(2)+9

f(2)=8+9

f(2)=17

The output values are -7, 1, 9, 17. So, the range of the function f(x) for the given domain is {-7, 1, 9, 17}.

Therefore, the correct option is D.

Answer:

The answer to your question is s = 399.5 m

Step-by-step explanation:

Formula

                   s = \sqrt{\frac{3V}{h}}

Data

V = 7 500 000 m³

h = 141 m

Substitution

                  s = \sqrt{\frac{3(7500000)}{141}}

                  s = \sqrt{\frac{22500000}{141}}

                 s = \sqrt{159574.47}

                 s = 399.46 meters ≈ 399.5 meters
