Mathematics
1 answer:
Yuliya22 [10]3 years ago
5 0

Answer:

x= 6

Step-by-step explanation:

Step 1: Write equation

2x - 5 = 7

Step 2: Solve for <em>x</em>

<u>Add 5 to both sides:</u> 2x = 12

<u>Divide both sides by 2:</u> x= 6

<u />

Step 3: Check

<em>Plug in x to verify if it's a solution.</em>

2(6) - 5 = 7

12 - 5 = 7

7 = 7

Calculate the length of each path using the law of cosines:

AB = √(8^2 + 8^2 - 2*8*8*cos(36)

AB = 4.94 ft.

XY = √(8^2 + 8^2 - 2*8*8*cos(79)

XY = 10.18 ft.

ZY = √(8^2 + 8^2 - 2*8*8*cos(65)

ZY = 8.60 ft.

XY is longer than ZY and ZY is longer than AB

The first choice is correct.

Differentiating a Logarithmic Function In Exercise, find the derivative of the function.
devlian [24]

Answer:

Dy/Dx=x ( 2 ln ( x ) − 1 )/ ln ^2 ( x)

Step-by-step explanation:

We have this function and let's derive it in terms of x.

y =x^2/In x

Dy/Dx=(x^2/In x)'=2/lnx *(x^2)'-(x^2/In x)'=> 2 x *ln ( x ) − x *ln ^2 ( x ) =x ( 2 ln ( x ) − 1 )/ ln ^2 ( x)

Natali5045456 [20]

Answer: R = {0, -3, -9, 5, 7}

Explanation: The range is the set of all y-coordinates for our ordered pairs.

So the range for this relation is {0, -3, -9, 5, 7}.

A certain four​-cylinder combination lock has 50 numbers on it.

It is a four cylinder combination lock

Each cylinder has 50 numbers

So we have to choose 4 numbers for 4 cylinders

_____ , ______ , ______, _____

you turn to a number on the first​ cylinder

We have 50 numbers so we have 50 combinations

__50___ , ______ , ______, _____

Repetitions are allowed so we do the same for remaining three

50 , 50 , 50 , 50

50 * 50 * 50* 50 = 6250000

There are 6250000 different lock combinations .
