I need some help with graphing again.

Rashid [163]

To find the x intercepts, we need to put the standard form equation into factored form.

Which two numbers multiply to -8 and add to -2?

$-4*2=-8$

$-4+2=-2$

So the factored form is

$(x-4)(x+2)$

That means the x intercepts are at $x=4,-2$

So now we have the x intercepts.

To find the vertex, we need to convert the standard form equation into vertex form.

The formula of vertex form is $y=a(x-h)^2+k$

Since the a value in the standard form equation is 1, the a value in vertex form is also one.

The h value can be found using the formula $h=\frac{-b}{2a}$

Which comes out to $\frac{2}{2}$ or 1.

To find the k value, we can just plug in what we got for h back into the equation.

$(1)^2-2(1)-8=-9$

So the vertex is $(1,-9)$ .

This also means the axis of symmetry is $x=-1$

Finally, to find the y intercept, we plug in 0 for x and solve.

$(0)^2-2(0)-8=-8$

So the y intercept is $(0,-8)$ .

What is 100 x 0.95=_____

kifflom [539]

Answer: 95

Step-by-step explanation:

That’s the same as 0.95 of 100. That’s because 0.95 represents 0.95 and 100 represents 100, the of is the same as x. You can switch the two numbers and you can still get the same answer. So, 0.95 of 100 is 95.

Olegator [25]

Answer:

(a) 74553

(b) 172120

(c) 234802

Step-by-step explanation:

Given

$y = \frac{340110}{1 + 377e^{-0.259t}}$

Solving (a): 1998

Year 1998 means that:

$t =1998 - 1980$

$t =18$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*18}}$

$y = \frac{340110}{1 + 377e^{-4.662}}$

$y = \frac{340110}{1 + 3.562}$

$y = \frac{340110}{4.562}$

$y = 74553$ --- approximated

Solving (b): 2003

Year 2003 means that:

$t = 2003 - 1980$

$t =23$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*23}}$

$y = \frac{340110}{1 + 377e^{-5.957}}$

$y = \frac{340110}{1 + 0.976}$

$y = \frac{340110}{1.976}$

$y = 172120$ --- approximated

Solving (c): 2006

Year 2006 means that:

$t = 2006 - 1980$

$t =26$

So, we have:

$y = \frac{340110}{1 + 377e^{-0.259*26}}$

$y = \frac{340110}{1 + 377e^{-6.734}}$

$y = \frac{340110}{1 + 0.4485}$

$y = \frac{340110}{1.4485}$

$y = 234802$ --- approximated
