What is the inverse of the function f(x) = 4x + 8?

Answer:

$7.198 * 10^6

Step-by-step explanation:

Given that :

Total Area of Alaska = 5.9 * 10^5 mi²

Cost of Alaska per square mile = $12.20

Total amount paid to purchase Alaska:

(Total area in square miles * Cost per square mile)

(5.9 × 10^5) * $12.20

(5.9*12.20) * 10^5

71.98 * 10^5 dollars

= $7.198 * 10^6

Hence, amount the United States paid Russia for the purchase of Alaska is approximately $7.198 * 10^6

Answer:

1. Write the expression:       (5.9 × 105)(12.2)

2. Multiply the decimal values:      

✔ 71.98

× 105

3. Write in scientific notation:      

✔ 7.198

×  

✔ 10 to the sixth power

The United States paid Russia approximately  

✔ $7,200,000

for Alaska.

2. A

3.C

Step-by-step explanation:

Answer:

Work = Force × distance = 500 × 15 = 7,500 J.

Hope this helps! Merry Christmas and Happy New Year!

Total work done by pushing the car for a distance of 15 m using a force of 500 N is 7500 Joule.

The total work done can be derived in terms of the products of force applied and the total distance covered.

Therefore,

Total work done = force × distance = 500 × 15 N-m = 7500 Joule

Hence, 7500 Joule work is done.

Answer:

ounces

Step-by-step explanation:

moat likely ounces because of the size of the ring

The correct answer from the choices listed above is the first option, ounces.

Weight is the measure of the force of gravity acting on a body.

The weight of a gold ring most likely is expressed in ounces. The weight of gold is measured in troy ounces (1 troy ounce = 31.1034768 grams), but its purity, or "fineness" has been measured in a few different ways: "parts fine," "% gold", and carats.

Hence, the answer is ounces.

Answer:

0.05n + 0.10 d =24.40

Step-by-step explanation:

Nickel is worth 0.05 of a dollar(1)

The system of equations below would be the best to use to find the number of nickels and dimes Anthony had at the end of the first week is:

n + d = 368

0.05n + 0.10d = 24.40

The number of nickels and dimes Anthony saved at the end of the first week can be determined using two equations. This is known as simultaneous equations.

The total number of nickels and dimes in the jar is 368. This can be represented with the equation:

nickels + dimes = 368

n + d = 368. This would be the first equation.

A nickel is equal to 0.05 of a dollar and a dime is equal to 0.1 of a dollar. The total sum of money in the jar is $24.40. This means that the value of dimes and nickels in the jar is $24.40. This can be represented with the equation: 0.05n + 0.10d = 24.40. This is the second equation.

Answer:

B on Edge

Step-by-step explanation:

Answer:

2 is the value that provides the same result with f(x) and g(x).

Step-by-step explanation:

You can solve this by saying:

f(x) = g(x)

and then solving for x.

So let's do it:

[tex]f(x) = g(x)\\-0.5x + 2 = 2x - 3\\2x + 0.5x = 2 + 3\\2.5x = 5\\x = 2[/tex]

This tells us that when x = 2, the two functions will have identical values.  Let's try them out to confirm it!

f(x) = -0.5x + 2

f(2) = -0.5 * 2 + 2

f(2) = -1 + 2

f(2) = 1

g(x) = 2x - 3

g(2) = 2 * 2 - 3

g(2) = 4 - 3

g(2) = 1

So we can see that 2 is the value that produces the same result in both charts.

The input value that produces the same output value in both charts is 2. so the correct answer is option D.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

here, we have,

You are given two functions  f (x) = -0.5X +2 and g(x) = 2x - 3

x      f(x)

-3     3.5

-2     3

-1     2.5

0     2

1      1.5

2     1

3     0.5

The second table is given below:-

x      g(x)

-3      

-2      

-1      

0    

1      

2      

3      

We will put the points and will find the value of functions:-

g(-3) = 2(-3) - 3 = -6 -3 = -9

g(-2) = 2 -(-2) -3 = -7

g(-1) = 2( -1) -3 = -3

g(0) = 2 - 0  - 3 = -3

g(1) = 2.1 - 3 = -1

g(2) = 2.2 -3 = 1

g(3) = 2.3 -3 = 3

Hence the second table will be

x      g(x)

-3      -9

-2      -7

-1       -5

0       -3

1        -1

2       1

The input value that produces the same output value in both charts is 2.

The original price of the pair of jeans is $ 68.75

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

The sale price of the jeans = $ 55.00

The discounted percentage of the pair of jeans = 20 %

Let the original price of the jeans be = A

To calculate the original price of the jeans ,

Original price of the jeans A will be discounted percentage less than and is equal to the sale price of the jeans

So ,

Original price of the jeans A - discounted percentage of the pair of jeans = Sale price of the jeans

And ,

A - ( 20/100 ) A = 55

( ( 100A - 20A ) / 100 )A = 55

(80/100 ) A = 55

( 4/5 ) A = 55

Multiply by 5/4 on both sides , we get

A = ( 55 x 5 ) / 4

A = 275/4

A = $ 68.75

Therefore , Original price of the jeans A = $ 68.75

Hence , the original price of the jeans is $ 68.75

Given :

An equation 2cot x = -3sec x .

To Find :

the values of x in [0, 360°) which satisfy the given equation.

Solution :

Converting cot x and sec x in the form of sin x and cos x.

[tex]\dfrac{2cos \ x}{sin\ x}= \dfrac{-3}{cosx}\\\\2cos^2 x +3 sin\ x =0\\\\2( 1 - sin^2 x ) + 3sin \ x = 0 \\\\2sin^2 x -3sin\ x -2 = 0\\\\2sin^2\x -4sin\ x + sin\ x -2 = 0\\\\2sin\ x( sin\ x - 2 )+ 1( sin \ x - 2 ) = 0\\\\sin \ x = \dfrac{-1}{2} \ or\ sin \ x = 2[/tex]

Neglecting sin x = 2 because sin x cannot be greater than 1.

x = π - π/6, π + π/6

x = 5π/6 and x = 7π /6

Therefore, the values of x in [0,360°) is  5π/6 and x = 7π /6 .

Answer:

The price of adult ticket is £38.

Step-by-step explanation:

First, you have to form equations in terms of a (adult) and c (child) :

[tex]2a + 4c = 152 - - - (1)[/tex]

[tex]a = 2c - - - (2)[/tex]

Next, you have to solve these equations by substitution :

[tex](2)→(1)[/tex]

[tex]2(2c) + 4c = 152[/tex]

[tex]8c = 152[/tex]

[tex]c = 152 \div 8[/tex]

[tex]c = 19[/tex]

[tex]substitute \: c = 19 \: into \: (2)[/tex]
