Answer:

Perpendicular

Step-by-step explanation:

Because the two lines don't have a "b" value in the equation y=mx+b, we know that both these lines are straight lines either horizontal or vertical. So, if we were to graph these, they would intersect and creat 4 90º angles, making it perpendicular (see graph as well)

Answer:

>

Step-by-step explanation:

-27/80 > -73/80

If you make a number line they are both in the negatives. If they are both in the negatives then whatever one is closer to 0 is greater.  

Answer:

>

Step-by-step explanation:

even tho 73 looks like a higher number when u add the negatives to the front whatever number looks like it is smaller is the higher number.

Answer:

25% of $8.00 is $2.00

Step-by-step explanation:

25% is basically 1/4 of something. So, if you divide $8.00 into four parts, you would get $2.00 for each part. This is why 25% of $8.00 is $2.00.

Answer:

$2

Step-by-step explanation:

Think you have 25/100 x of 8

100/25 is the same as 8/x:

X=8/100 divided by 25=$2

Answer:

29,100

Step-by-step explanation:

Answer:

-7

Step-by-step explanation:

30-16= -5n +3n

14 = -2n

multiplying both by half,u have -

7 = -n

multiply both by -1

7 = n

Answer:

Adult= $24

child= $21

Step-by-step explanation:

first let's create an equation for each one.

Day 1: 7x+8y=168

day 2: 14x+13y=294

By doing so we can either graph and get the points for x,y or we can substitute each (x=0) (y=0) and solve manually.

x-int.= (24,0)

y-int.=(0,21)

Answer:

To determine to measure of the unknown angle

Step-by-step explanation:

If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2

"To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2."

Step-by-step explanation:

Answer:

y'' = 18x(x³ + 8)⁴(17x³ + 16)

General Formulas and Concepts:

Calculus

Derivative Notation dy/dx

Derivative of a constant is 0.

Basic Power Rule:

Chain Rule: [tex]\frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)[/tex]

Product Rule: [tex]\frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)[/tex]

Step-by-step explanation:

Step 1: Define

y = (x³ + 8)⁶

Step 2: Find 1st Derivative (dy/dx)

Step 3: Find 2nd Derivative (d²y/dx²)

Answer:

[tex]\frac{d^{2}y}{dx^{2}} = 180x.(x^{3} +8)^{4}[/tex]

Step-by-step explanation:

This question requires use of the chain rule:

[tex]y = (x^{3} + 8)^{6}[/tex]

Let:

[tex]u = x^{3} + 8[/tex]

Then:

[tex]y = u^{6}[/tex]

And:

[tex]\frac{dy}{dx} = \frac{dy}{du}. \frac{du}{dx}\\\\\frac{d^{2}y}{dx^{2} } = \frac{d^{2}y}{du^{2}}. \frac{d^{2}u}{dx^{2}}\\\\\frac{dy}{du} = 6u^{5}\\\\\frac{d^{2}y}{du^{2}} = 30u^{4}\\\\\frac{du}{dx} = 3x^{2}\\\\\frac{d^{2}u}{dx^{2}} = 6x[/tex]

So:

[tex]\frac{dy}{dx} = 6u^{5}.3x^{2}\\\\\frac{dy}{dx} = 18u^{5}x^{2}\\\\[/tex]

And:

[tex]\frac{d^{2}y}{dx^{2}} = 30u^{4}.6x\\\\\frac{d^{2}y}{dx^{2}} = 180u^{4}x[/tex]

Finally, substitute u for its equivalent expression in x:

[tex]\frac{d^{2}y}{dx^{2}} = 180x.(x^{3} +8)^{4}[/tex]
