Answer:

$-16x^{2} y^{2}z^{2}$

Step-by-step explanation:

Let's calculate the answer to the second parenthesis. Just multiply throughout to get -8xyz. Then, multiply the first parenthesis by the second. Multiply the constants (-8 and 2) first to get -16, multiply the x's together to get x^2, the y's together to get y^2, and the z's together to get z^2. Put it all together to get $-16x^{2} y^{2}z^{2}$ .

HELP PLEASE 18 POINTS

ICE Princess25 [194]

Answer:

Step-by-step explanation:

line 1 m=y2-y1 / x2-x1 [formula for slope ]

m= 0 - (-3) / 8-(-4)

m= 3 /12

m= 1/4 slope of line 1

line2

m = 2-6 / 0-(-1)

m = -4 / 1

m = -4 slope of line 2

line 3

m = -4 - (-7) / -3 - 6

m = 3 / -9

m = - 1/3 slope of line 3

lines 1 & 2 perpendicular b/c they are reciprocals with a sign change :)

lines 1 & 3 neither.. differet slopes and not reciprocals

lines 2 & 3 perpendicular b/c they are reciprocals with a sign change :)

Help with 5b please . thank you.

Answer:

See explanation

Step-by-step explanation:

We are given f(x)=ln(1+x)-x+(1/2)x^2.

We are first ask to differentiate this.

We will need chain rule for first term and power rule for all three terms.

f'(x)=(1+x)'/(1+x)-(1)+(1/2)×2x

f'(x)=(0+1)/(1+x)-(1)+x

f'(x)=1/(1+x)-(1)+x

We are then ask to prove if x is positive then f is positive.

I'm thinking they want us to use the derivative part in our answer.

Let's look at the critical numbers.

f' is undefined at x=-1 and it also makes f undefined.

Let's see if we can find when expression is 0.

1/(1+x)-(1)+x=0

Find common denominator:

1/(1+x)-(1+x)/(1+x)+x(1+x)/(1+x)=0

(1-1-x+x+x^2)/(1+x)=0

A fraction can only be zero when it's numerator is.

Simplify numerator equal 0:

x^2=0

This happens at x=0.

This means the expression,f, is increasing or decreasing after x=0. Let's found out what's happening there. f'(1)=1/(1+1)-(1)+1=1/2 which means after x=0, f is increasing since f'>0 after x=0.

So we should see increasing values of f when we up the value for x after 0.

Plugging in 0 gives: f(0)=ln(1+0)-0+(1/2)0^2=0.

So any value f, after this x=0, should be higher than 0 since f(0)=0 and f' told us f in increasing after x equals 0.

What is the discriminant <br><br> 3g^2+10= -15g

Ilia_Sergeevich [38]

$\bf 3g^2+10=-15g\implies 3g^2+15g+10=0
\\\\\\
\begin{array}{llcccll}
& 3g^2& +15g& +10\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\\\\\\
discriminant\implies b^2-4ac\implies 15^2-4(3)(10)$
