There are many different ways of representing the equation of a line. With the given information, the best form of the equation to use is point-slope form which can be written as y-y_{1}=m(x-x_{1}) where (x_{1},y_{1}) is the x and y coordinates of a given point on the line and m is the slope of the line. Since you are given that the slope of the line is 3 and has the point (-1,-8), the equation should look like y+8=3(x+1), which is letter choice D.

What does the graph of y=(x + 2)(x + 1)(x - 3)2 do near the point (3,0)?
IRINA_888 [86]

Check out the graph below. We see that (3,0) is a root or x intercept. More specifically, the graph only touches the x axis at this point, rather than cross over (in contrast to a root like (-2,0) ). We say that the root here is of multiplicity 2. The multiplicity is due to the exponent of 2 over the (x-3) factor.

You can also say that the graph is decreasing on the left side of (3,0) and then it bounces off the root x = 3 to increase afterward. In this region, the graph never goes below the x axis.

Translate the sentence into an equation.
Andreas93 [3]
<h2>Translating Sentences into Equations</h2>

A key part of this is recognizing certain words to change into operations or numbers:

  • <em>quotient</em> = divide
  • <em>three more</em> = add 3
  • <em>'a/the number' </em>= use a variable (in this case, it's <em>w</em>)

<h2>Solving the Question</h2>

We're given:

  • Three more than the quotient of a number and 7 equals 6
    ⇒ 'the quotient of a number and 7' tells us we divide <em>w</em> by 7:
  • Three more than \dfrac{w}{7} equals 6
    ⇒ 'three more than' means we add 3 to the fraction:
  • \dfrac{w}{7}+3 equals 6
  • \dfrac{w}{7}+3=6

<h2>Answer</h2>

\dfrac{w}{7}+3=6

(h) when is the particle speeding up? (enter your answer using interval notation.) (2,4)∪(6,8) incorrect: your answer is incorre
OverLord2011 [107]
The position of the particle as function of time is given as
f(t)=cos( \frac{\pi t}{4} )

The velocity as function of time is
v(t)= - \frac{\pi}{4} sin( \frac{\pi t}{4} )

A graph of f(t) versus t and of v(t) versus t is shown below.
The velocity increases in the intervals t = (2, 6) and t = (10, 14) and with a periodicity of 8.

In the range t = [0, 16], the velocity increases in the interval t = (2,6)∪(10, 14).

Answer: (2,6)∪(10,14)
