Write the following in standard form: 6x^3-8x^4+5x+12x^2-9

kondaur [170]

Answer:

$-8x^4 + 6x^3 + 12x^2 + 5x -9$

Step-by-step explanation:

To write a polynomial in standard form, list its terms from highest to lowest degree. The degree of a term is represented by its exponents. Thus, rearrange the terms so that the terms with the highest exponents are first and the ones with the lowest are last.

$6x^3-8x^4+5x+12x^2-9\\-8x^4 + 6x^3 + 12x^2 + 5x -9$

Thus, $-8x^4 + 6x^3 + 12x^2 + 5x -9$ is the answer.

Each side of a square is increasing at a rate of 6 cm/s. At what rate (in cm2/s) is the area of the square increasing when the a

My name is Ann [436]

36 cm²s⁻¹ is the rate at which the area of the square is increasing.

Given each side of the square is increasing at a rate of 6cm/s

Area, A = s², s is the side length

=> $\frac{dA}{dt} =\frac{dA}{ds}* \frac{ds}{dt} =2s*(\frac{ds}{dt} )$ {chain rule of differentiation}

$\frac{ds}{dt}$ = 6 cm/s

When A = 9 cm² => 9 = s²

=> s = √(9) => s = 3 cm

Hence, $\frac{dA}{dt}$ = 2 × 3 × 6 = 36 cm²s⁻¹

Hence, 36 cm²s⁻¹ is the rate at which the area of the square increases

When a result from a simple is extended to the population

hjlf

Answer:

You can opt to study the entire population when the population is well defined(Complete sampling frame) and small.

It can eliminate any potential bias occurring through sampling technique, but other than that it is really not justified to consume more resources and time.

The formula for the circumference of a circle is c=2pir where r is the radius and c is the circumference. The equation r is r=c/

photoshop1234 [79]

Answer:

r = 8

Step-by-step explanation:

The circumference of a circle is given by :

$C=2\pi r$ ...(1)

We need to find the value of r when C = 16π

Solving equation (1)

$r=\dfrac{C}{2\pi}\\\\r=\dfrac{16\pi}{2\pi}\\\\r=8$

So, the value of r is 8. Hence, the correct option is (b).
