Rewrite each expression as a polynomial in standard form: x^2-5x+6 ÷ x-3 + x^3-1 ÷ x-1

iragen [17]

Answer:

So in standard form equation will be $x^2+2x-1$

Step-by-step explanation:

We have given expression $\frac{x^2-5x+6}{x-3}+\frac{x^3-1}{x-1}$

Let first we solve first part of the expression

So $\frac{x^2-5x+6}{x-3}=\frac{x^2-3x-2x+6}{x-3}=\frac{(x-3)(x-2)}{x-3}=x-2$

Now second part $\frac{x^3-1}{x-1}$

We know the algebraic identity $a^3-b^3=(a-b)(a^2+ab+b^2)$

So by using this identity

$\frac{x^3-1}{x-1}=\frac{(x-1)(x^2+x+1)}{x-1}=x^2+x+1$

Now adding first and second part

$x-2+x^2+x+1=x^2+2x-1$

So in standard form equation will be $x^2+2x-1$

What is the mean of the data set? {11, 14, 15, 16, 16, 18, 20, 20, 22, 22} A. 11 B. 15.6 C. 17.4 D 18

Mademuasel [1]

Answer:

C. 17.4

Step-by-step explanation:

add all the numbers and then divide

11 + 14 + 15 + 16 + 16 + 18 + 20 + 20 + 22 + 22 = 174

then divide by the amount of numbers there is which is 10.

174/10 = 17.4

A park ranger would like to clear more than 10 mi of trail. So far, he has cleared 2 mi. From now on, he can clear 3/4 mi of tra

blondinia [14]

Answer: The answer is (b) The ranger will need to clear trail for more than 10 2/3 additional hours.

Step-by-step explanation: Given that a park ranger would like to clear more than 10 mi of trail. Till now, he has cleared 2 mi. From now on, he can clear 3/4 mi of trail each hour.

Since 2 mi of the trail has already been cleared, so the trail that is left to be cleared = 10 - 2 = 8 mi.

Let, the park ranger will work for 'x' more hours. So, we have

$\dfrac{3}{4}\times x=8\\\\\Rightarrow 3x=32\\\\\Rightarrow x=\dfrac{32}{3}\\\\\Rightarrow x=10\dfrac{2}{3}.$

Thus, the park ranger will need to work for 10 2/3 more hours.

Hence, the correct option is (b) The ranger will need to clear trail for more than 10 2/3 additional hours.
