Answer: This is a quadratic equation in x and can be solved using the quadratic formula:    x = (-b +_ (b^2 - 4 ac)^1/2) / (2 * a)

or (-7 +- (49 - (4 * 2 * 6))^1/2)  / (2 * 2)  where a=2, b=7, and c=6

and x = (-7 +- (49 - 48)^1/2) / 4 = (-7 +- 1) / 4

giving x = -8/4 and -6/4 or -2 and =3/2

Graph the function f(x) = x3 – 4x – 1. Which are approximate solutions for x when f(x) = 0?
Scilla [17]
If f(x) is = to 0 then that means that you would have to plug the 0 in for all of the x that are in the function and the solve it.
f(x)= x3-4x-1
f(0)= (0)3-4(0)-1
0        0        0 -1
-1 
so that means that -1 would be the answer for the function

What is the perimeter of the triangle below? Round to the nearest hundredth.
Keith_Richards [23]

You're going to need to use Pythagoras' theorem to work this one out!

As you know, the perimeter of a triangle is just all the lengths of the sides added up.

We'll start with side AC first. We can see that A is (-8, -4) and C is (-6, -2). That means to get from A to C, we need to go 2 units to the right, and 2 units up. Which means we have our two sides to work out the length from Pythagoras' theorem. 2² + 2² = c², c = √8.

Now we'll move onto side AB. We already know A is (-8, -4) from above, and B is (-7, -8). That means to get from A to B, we have to go 4 units down, and 1 unit to the right. So once again: 4² + 1² = c², c = √17.

Lastly, we'll work out side BC. We know that B is (-7, -8) and C is (-6, -2). That means to get to C from B, we have to go 1 unit to the right and 6 units up. So, again: 1² + 6² = c², c = √37.

Now that we have all of our lengths, we simply just add them up!

√8 + √17 + √37 ≈ 13.03 units.

(I've also attached something to help you visualise how I worked it out.)

A color printer prints 7 pages in 3 minutes.
mojhsa [17]

Answer:

2 pages per minute

Step-by-step explanation:

when you divide 7 by 3, your answer would be 2.3333333333 and so on.

however, you can say

you should say it prints 2 whole pages a minute.

i hope this helps!
