Show that x=2 is a solution of the equation X^3-x-6

My name is Ann [436]

Answer:

x = 2 is the solution of x^3 - x - 6

Step-by-step explanation:

(x^3) - x - 6 = 0

If x = 2,

--> (2^3) - 2 - 6

= 8 - 2 - 6 = 8 - 8 = 0.

(3.6x10^-5)÷(1.8x10^2) in standard form

Lerok [7]

Answer:

The standard form of $\left(3.6 \times 10^{-5}\right) \div\left(1.8 \times 10^{2}\right)$ is 0.0000002

Solution:

We have to write $\left(3.6 \times 10^{-5}\right) \div\left(1.8 \times 10^{2}\right)$ in standard form.

$=\frac{3.6 \times 10^{-5}}{1.8 \times 10^{2}}$

By dividing 3.6 by 1.8 we get “2”, hence the above equation becomes,

$=\frac{2 \times 10^{-5}}{10^{2}}$

We know that $\frac{x^{a}}{x^{b}}=x^{a-b}$

Therefore the above equation becomes,

$=2 \times 10^{-5-2}$

$=2 \times 10^{-7}$

since the exponent of 10 is negative , therefore 7 zeros are written on the left hand side of the number.

= 0.0000002

Hence the standard form of $\left(3.6 \times 10^{-5}\right) \div\left(1.8 \times 10^{2}\right)$ is 0.0000002

The car you want cost 25,750. If the sales tax rate is 6.5% the how much sales tax will be added? What is the total cost for the

lilavasa [31]

Answer:The total cost for the car including tax is $27423.75

Step-by-step explanation:

The initial price of the car that you want is 25,750. If the sales tax rate is 6.5%, it means that the amount of sales tax would be

6.5/100 × 25750 = 0.065 × 25750 = 1673.75

The total cost for the car including tax would be the sum of the initial cost of the car and the amount of tax. It becomes

25750 + 1673.75 = $27423.75
