Add all the numbers together and divide them by the number of numbers you added to get the mean (in other words the average)

Find the value of 8.3 × 24.2 × 0.03. Round your answer to the nearest hundredth.

harina [27]

<span>So we need to find the value of 8.3*24.2*0.03 and round it to the nearest hundredth. So lets multiply the numbers first: 8.03 * 24.2 * 0.03 = 6.0258 and now we need to round it to the nearest hundreth. The nearest hundreth is .03 and we get: 6.03 so the correct answer is D.</span>

One factor of the polynomial 3x3 + 20x2 - 21x + 88 is (x + 8). what is the other factor of the polynomial? (note: use long divis

Snezhnost [94]

The other factor of the polynomial is a. 3x2-4x+11

Given polynomial is 3x3 + 20x2 - 21x + 88 and the factor is (x+8)

We need to find another factor using long division method

So,

We will divide the polynomial by the factor to find the another factor

Therefore,

$\sqrt[x+8]{3x^3+20x^2-21x+88}$

Now calculating

First multiplying $3x^2$ with (x+8) so , $3x^2$ will be in the quotient

We get $3x^3+24x^2$

simplifying the calculation for $3x^3+20x^2$ and $3x^3+24x^2$

We get the remainder is $-4x^2-21x+88$

Second we will multiply -4x with (x+8) Where -4x will be in the quotient

We get $-4x^2-32x$ and then we will simplify the equation

We get 11x +88 as a remainder

The quotient we get is $3x^2-4x$

Third we will multiply +11 with (x+8) Where +11 will be in the quotient

we get 11x+88

Simplifying the equation we get the remainder 0

So the quotient we get is (3x2 - 4x+11)

Hence the another factor of the polynomial is (3x2 - 4x+11)
