Answer:

[tex]x=-4\text{ and } x=3[/tex]

Step-by-step explanation:

We are given the second derivative:

[tex]g''(x)=(x-3)^2(x+4)(x-6)[/tex]

And we want to find its inflection points.

To do so, we will first determine possible inflection points. These occur whenever g''(x) = 0 or is undefined.

Next, we will test values for the intervals. Inflection points occur if and only if the sign changes before and after the point.

So first, finding the zeros, we see that:

[tex]0=(x-3)^2(x+4)(x-6)\Rightarrow x=-4, 3, 6[/tex]

So, we can draw the following number-line:

<----(-4)--------------(3)----(6)---->

Now, we will test values for the intervals x < -4, -4 < x < 3, 3 < x < 6, and x > 6.

Testing for x < -4, we can use -5. So:

[tex]g^\prime^\prime(-5)=(-5-3)^2(-5+4)(-5-6)=704>0[/tex]

Since we acquired a positive result, g(x) is concave up for x < -4.

For -4 < x < 3, we can use 0. So:

[tex]g^\prime^\prime(0)=(0-3)^2(0+4)(0-6)=-216<0[/tex]

Since we acquired a negative result, g(x) is concave down for -4 < x < 3.

And since the sign changed before and after the possible inflection point at x = -4, x = -4 is indeed an inflection point.

For 3 < x < 6, we can use 4. So:

[tex]g^\prime^\prime(4)=(4-3)^2(4+4)(4-6)=-16<0[/tex]

Since we acquired a negative result, g(x) is concave down for 3 < x < 6.

Since the sign didn't change before and after the possible inflection point at x = 3 (it stayed negative both times), x = -3 is not a inflection point.

And finally, for x > 6, we can use 7. So:

[tex]g^\prime^\prime(7)=(7-3)^2(7+4)(7-6)=176>0[/tex]

So, g(x) is concave up for x > 6.

And since we changed signs before and after the inflection point at x = 6, x = 6 is indeed an inflection point.

Answers

Answer:

X+2y=4

4+2y=x

2(2+y)=x

2x-2y=5

2(x-y)=5

x-y=5/2

Answer:

(x, y) = (3, 1/2)

Step-by-step explanation:

x + 2y = 4

2x - 2y = 5

There is more than one way to do this. I will do it by substitution.

From the first equation, x + 2y = 4, so x = (-2y) + 4

Now, in the second equation, I will replace x with (-2y + 4)

2(-2y + 4) - 2y = 5

-4y + 8 -2y = 5

-6y + 8 = 5

-6y = -3

6y = 3

y = 3/6

--------------------------------->  y = 1/2, one part of the answer

Now I can go back to the first equation, and relpace 'y' with 1/2

x + 2(1/2) = 4

x + 1 = 4

----------------------------------->  x = 3, the other part of the answer

So now we believe the solution is (x, y) = (3, 1/2)

Now check the answer, back in the original equations!!

------> In the first equation, we would have 3 + 2(1/2) = 4.

                                                                       3 + 1 = 4

                                                                       That is true

-------> In the second equation, we would have 2(3) - 2(1/2) = 5

                                                                                6 - 1 = 5

                                                                          That is true

Our answer is found and checked.

Triangle A is a scaled version of triangle B. The dimensions of triangle B are twice the dimensions of triangle A. The area of
triangle B is 144 sq cm.
What is the area of triangle A?

Answers

Answer:

576 sq cm

Step-by-step explanation:

For example imagine a rectangle, the area of which is width * height = area

If you multiply the dimensions by 2 you multiply the width AND the height which is 2 * width * 2 * height = 4 * width * height

This is true for all scalings, if you times the dimensions by n, you times the area by n^2

144 * 2^2 = 576

Find the measure of the missing angles.

Answers

Answer:

angles b and c should be 153° each.

Step-by-step explanation:

We know the smaller angle is 27°. The other small angle, vertical to the 27° angle is also 27° because they are vertical angles. Along the lines, two angles should form 180°. So 180-27=153°. All together the angles should be 360°. Check your answer by doing 153+153+27+27=360. therefore the missing angles are both 153°

which binomial is a factor of 8x^2y^3-18y

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

[tex]8x^2y^3-18y[/tex]

Apply exponent rule:   [tex]a^{b+c}=a^ba^c[/tex]

[tex]8x^2y^3-18y=8yy^2-18y[/tex]    ∵ [tex]x^2y^3=yy^2[/tex]

                    [tex]=4\cdot \:2yy^2+9\cdot \:2y[/tex]

Factor out common term 2y

                    [tex]=2y\left(4x^2y^2-9\right)[/tex]

We know that the Binomial is an expression that consists of two terms. Thus,

(4x²y²- 9) represents the binomial factor of [tex]8x^2y^3-18y[/tex]

We can further simplify by Factoring 4x²y² - 9:  (2xy + 3) (2xy - 3)

                      [tex]=2y\left(2xy+3\right)\left(2xy-3\right)[/tex]

Here:

(2xy + 3) and (2xy -3) are the binomial factors of [tex]8x^2y^3-18y[/tex] as each of them consists of two terms.
