Which function represents a horizontal shift of f(x)=5^x by 4 units to the right?

Answers

If you have a function y = f(x), the transformation along the x-axis is given by:

y = f(x+a) ⇒ This is the translation to the LEFT by 'a' units
y = f(x-a) ⇒ This is the translation to the RIGHT by 'a' units

So you have, f(x) = 5ˣ, translated 4 unit right will give g(x) = 5⁽ˣ⁻⁴⁾

Answer: [tex]g(x)=5^{x-4}[/tex]

Step-by-step explanation:

When a function f(x) is shifted horizontally by n units to the right , the new function will become :-

[tex]g(x)=f(x-n)[/tex]

The given function : [tex]f(x)=5^x[/tex]

Now, if the given function shifted 4 units to the right , then the new function will become :

[tex]g(x)=f(x-4)[/tex]

[tex]g(x)=5^{x-4}[/tex]

Hence, the  function represents a horizontal shift of [tex]f(x)=5^x[/tex] by 4 units to the right will be :-

[tex]g(x)=5^{x-4}[/tex]

The change in the value of an account when given to the nearest dollar

Answers

The net change in the value of the account, when rounded to the nearest dollar, is $550.

To find the net change in the value of the account, you would sum up the amounts deposited, subtract the amounts withdrawn, and add the interest earned:

Net change = (Deposits - Withdrawals) + Interest earne

Net change = ($500 - $250) + $300

            = $250 + $300

            = $550

Therefore, the net change in the value of the account, when rounded to the nearest dollar, is $550.

The probable question maybe:

"What is the net change in the value of an investment account after depositing $500, withdrawing $250, and earning $300 in interest, when rounded to the nearest dollar?"

We need to find what we need to add to [tex]2\frac{3}{8}[/tex] to make 6.

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

The fraction [tex]2\frac{3}{8}[/tex] can be written as 19/8

Let x be the number added to given fraction, that is

19/8 +x=6

⇒ x=6-19/8

⇒ x= (48-19)/8

⇒ x= 29/8

⇒ x= [tex]3\frac{5}{8}[/tex]

Hence, the number must be added to [tex]2\frac{3}{8}[/tex] to make 6 is [tex]3\frac{5}{8}[/tex].

Two cars on a roller coaster hold 14 riders combined. If 12 cars are linked together, how many riders can fit on the roller coaster at one time? Explain how to solve this problem.

Answers

I want to say it's 84 combined because two roller coaters can hold 14 so seperately it's 7. 7x12=84 so I believe the answer is 84. I'm sorry if it's wrong.

Answer:

The rate of riders to cars is 14 divided by 2. So the unit rate is 7 riders per car. Multiply 7 riders by 12 cars to find that 84 riders can fit on the roller coaster at one time.

How to simplify 6/18

Answers

The numerator (12) and the denominator (18) are both divisible by 6 (so the largest number that goes exactly into both 12 and 18 is 6 and therefore the greatest common factor is 6). Therefore if you divide the numerator and denominator by 6, you can write the fraction as (12/6)/(18/6) = 2/3.

The simplified form of [tex]\frac{6}{18}[/tex] is [tex]\frac{1}{3}[/tex].

To simplify the fraction [tex]\frac{6}{18}[/tex], follow these steps:

Find the greatest common divisor (GCD) of the numerator and the denominator. The numerator is 6 and the denominator is 18. The greatest common divisor of 6 and 18 is 6.

Divide both the numerator and the denominator by their GCD.

When we divide the numerator 6 by 6, we get [tex]\frac{6}{6} = 1[/tex].

When we divide the denominator 18 by 6, we get [tex]\frac{18}{6} = 3[/tex].

Write the simplified fraction: After dividing both parts by 6, the fraction [tex]\frac{6}{18}[/tex] simplifies to [tex]\frac{1}{3}[/tex].

The mass of the sun is 2.13525×1030 kilograms. The mass of Mercury is 3.285×1023 kilograms. How many times greater is the mass of the sun than the mass of Mercury? Drag and drop the values into the boxes to represent the answer in scientific notation. 0.0656.565.5​106​​​107​ ​108​

Answers

Given that the mass of the sun is 2.13525×1030 kilograms, and the mass of Mercury to be 3.285×1023 kilograms. We determine how many times greater the mass of the sun is relative to the mass of Mercury by getting the ratio of their respective masses. With this, we compute the ratio to be 2.13525×1030/3.285×1023 which is equal to 6500000. With this calculation, we can infer that the mass of the sun is 6.5x106 times greater than the mass of mercury.

What's the prime factorization of 105

Answers

105 is a composite number. 105 = 1 x 105, 3 x 35, 5 x 21, 7 x 15. Factors of 105: 1, 3, 5, 7, 15, 21, 35, 105. Prime factorization: 105 = 3 x 5 x 7.

The prime factorisation of 105 is therefore 3 * 5 * 7.

Prime factorization

We can factorize 105 into its prime factors by dividing it by prime numbers up to the point when we can no longer divide it. Here is how it works:

Divide 105 by the following prime number, 3, for a result of 35.

35 divided by the following prime number, 5, yields a result of 7 that is:

35/5 = 7

The seventh prime number has been reached. The prime factorisation of 105 is therefore 3 * 5 * 7.

Thus, 3 * 5 * 7 is the prime factorization of 105.

Jillian is selling boxes of cookies to raise money for her basketball team. The 10 oz. box costs $3.50, while the 16 oz. box costs $5.00. At the end of one week, she collected $97.50, selling a total of 24 boxes. The system of equations that models her sales is below. x+ y= 24 3.50x + 5.00y = 97.50 Solve the system of equations. How many 10 oz. boxes were sold?

Answers

The answer would be 15 boxes!

Answer:

There are 15 boxes of 10 oz boxes

Step-by-step explanation:

Let the number of boxes of 10 oz = x

and let the number of boxes of 16 oz = y

By the statement

"Total number of boxes sold is 24"

Equation for the statement will be

x + y =24 ---------------(1)

By the  statement

"she collected $97.50 while rate of 10 oz box is $3.50 and rate of 16 oz box is $5.00."

Equation for the statement will be

1.5x + 5y = $97.50 ------------(2)

From equation (1) we put the value of y = 24 - x in equation (2)

1.5x + 5(24 - x) =  97.50

1.5x + 120 - 5x = 97.50

-3.5x = 97.50 - 120

3.5x = 22.50

x = [tex]\frac{22.5}{1.5}[/tex]

x = 15

Therefore, number of 10 oz boxes is 15.
