1.18. A fish tank has a base, B, with an area, in square inches, modeled by B(x) = 2x + 6x + 4.

Alekssandra [29.7K]

Answer:

The volume of fish tank is $V(x)=2x^3+12x^2+22x+12$

Step-by-step explanation:

Area of Base of fish tank = $Length \times Breadth$

We are given that A fish tank has a base, B, with an area, in square inches, modeled by $B(x) = 2x^2 + 6x + 4.$

So, $Length \times Breadth =2x^2 + 6x + 4.$

Height of tank = x+3

Volume of tank = $Length \times Breadth \times Height$

So, Volume of tank = $(2x^2 + 6x + 4)(x+3)$

Volume of Tank = $2x^3+6x^2+4x+6x^2+18x+12=2x^3+12x^2+22x+12$

Hence The volume of fish tank is $V(x)=2x^3+12x^2+22x+12$

Apply the laws of exponents, calculate the result and express the result in scientific notation, and as a decimal:

DochEvi [55]

We are given

$\frac{(4.1\times 10^{3})(2.8\times 10^{-7})}{(3.1\times 10^{-5})}$

We can move like terms altogether

$\frac{(4.1\times 10^{3})(2.8\times 10^{-7})}{(3.1\times 10^{-5})}=\frac{4.1\times 2.8}{3.1}\times \frac{10^{3}\times 10^{-7}}{10^{-5}}$

now, we can use property of exponent

$a^m\times a^n=a^{m+n}$

$=\frac{4.1\times 2.8}{3.1}\times \frac{10^{3-7}}{10^{-5}}$

We can use another exponent property

$\frac{a^m}{a^n} =a^{m-n}$

so, we get

$=\frac{4.1\times 2.8}{3.1}\times 10^{3-7+5}$

$=\frac{4.1\times 2.8}{3.1}\times 10^{1}$

$=3.70323\times 10^{1}$

So, the result in scientific notation is

$=3.70323\times 10^{1}$ ..........Answer

So, the result as a decimal is

$=37.0323$ .............Answer

Find the value of x, for which : (81) -4 ÷ (729) 2-x = 9 /4x

tamaranim1 [39]

Answer:

$\huge{x = \frac{236164}{9477} = 24 \frac{8716}{9477}}$

Step-by-step explanation:

$(81) - 4 \div (729)2 - x = \frac{9}{4} x$

$81 - \frac{4}{729} \times 2 - x = \frac{9}{4} x$

$81 - \frac{8}{729} - x = \frac{9}{4} x$

$\frac{59041}{729} - x = \frac{9}{4} x$

$236164 - 2916x = 6561x$

$- 2916x - 6561x = - 236164$

$- 9477x = - 236164$

$\boxed{\green{x = \frac{236164}{9477} = 24 \frac{8716}{9477}}}$
