In the number 555.55 each digit is a 5 but the value of each 5 is different based on its place in the number. How does the value of the 5 in the tenths place compare to the value of the underlined digit 5

To convert the number 1,340,000 into scientific notation, move the decimal point 6 places to the left to get 1.34, then place this as an exponent on 10 to get 1.34 x 10^6.

In scientific notation, large numbers are simplified by moving the decimal point to the left until we have a number between 1 and 10. We then use an exponent on 10 to indicate how many places the decimal point has been moved. If you take a look at the number 1,340,000, the decimal point is technically at the end of the number right now. In order to express this number in scientific notation, we move the decimal point 6 places to the left, which gives us 1.34. The number of places we moved the decimal point to the left becomes the exponent on 10. Therefore, 1,340,000 in scientific notation is 1.34 x 10^6.

Step-by-step explanation:

Answer: 81 children and 92 adults

Step-by-step explanation:

To solve the exercise, check the data we have from the question:

Total people: 173

Adult tickets price: $5

Children tickets price: $3

Total revenue: $703

We need to know how many of each kind of ticket were sold. To do so, we can show the data as two equations:

Equation 1:

[tex]TotalRevenue = Adults*5 + Children*3[/tex]

[tex]703=5a+3c[/tex]

Equation 2:

[tex]a+c=173[/tex]

Where a represents adults who attended the event and c represents children who attended the event. We can replace one of the unknown quantities following:

[tex]a=173-c[/tex]

[tex]703=5(173-c)+3c[/tex]

Solving:

[tex]703=865-5c+3c[/tex]

[tex]5c-3c=865-703[/tex]

[tex]2c=162[/tex]

[tex]c=81[/tex]

Then, we replace c on equation 2:

[tex]a=173-81[/tex]

[tex]a=92[/tex]

Mr. Adams spent $36.25 on 12.5 gallons of regular gasoline. To find the cost per gallon, divide the total cost by the number of gallons, resulting in a cost of $2.90 per gallon of regular gasoline at Greg's gas station.

To determine the cost per gallon for regular gasoline, we need to divide the total amount spent by Mr. Adams at Greg's gas station by the number of gallons of gasoline he purchased. In this case, Mr. Adams spent $36.25 on 12.5 gallons of regular gasoline.

Step-by-step calculation:

Write down the total cost of gasoline: $36.25.

Write down the total gallons of gasoline purchased: 12.5 gallons.

Divide the total cost by the number of gallons to find the cost per gallon: $36.25 \/ 12.5 gallons.

Perform the division: $36.25 \/ 12.5 gallons = $2.90 per gallon.

Therefore, the cost per gallon for regular gasoline at Greg's gas station is $2.90.

Answer:

The required function -  [tex]g(x)=\frac{1}{2}(3)^{-x}[/tex]

Step-by-step explanation:

Given : Function represents g(x), a reflection of [tex]f(x) =\frac{1}{2}(3)^x[/tex] across the y-axis

To find : Which function represents the g(x)?

Solution :

The function [tex]f(x) =\frac{1}{2}(3)^x[/tex]

The function f(x) reflected across y-axis to form g(x)

The reflection of the point (x,y) across  the y-axis is the point (-x,y).

f(x,y)→f(-x,y) , the graph of f(x) is reflected across y-axis.

Let [tex]y=\frac{1}{2}(3)^x[/tex]

After reflection across y-axis is

[tex]g(x)=\frac{1}{2}(3)^{-x}[/tex]

The required function.

To find the number of notepads bought, we can set up an equation by subtracting the cost of the magazine from the total cost and equating it to the cost of the notepads. By solving the equation, we find that you bought 4 notepads.

To solve this problem, we can start by setting up an equation. Let's assume the number of notepads bought is 'x'. We know the magazine cost $6, so the cost of the notepads is $18 - $6 = $12. Since each notepad costs $3, the equation becomes 3x = 12. To find the value of 'x', we can divide both sides of the equation by 3. So, x = 12/3 = 4.

Therefore, you bought 4 notepads.

If your equation is ...

then it has no real solutions, and certainly no integer solutions.

We want to get a quadratic equation by knowing its tangent line at a point. Remember that the tangent line is given by the derivative of the equation.

We will find that the parabola is:

y = 3*x^2  - 4*x

We start with the tangent line:

y₂ = 8*x - 12

The slope of this tangent line is equal to the derivative of our parabola evaluated in x = 2.

Our parabola is y = a*x^2 + b*x

Derivating we get:

y' = 2*a*x + b

Then we have:

2*a*2 + b = 8

And we also know that our parabola passes through the point (2, 4), then we must have:

4 = a*2^2 + b*2

Then we have a system of equations:

2*a*2 + b = 8

4 = a*2^2 + b*2

First we can simplify the equations:

4*a + b = 8

4 = 4*a + 2*b

We can isolate 4*a in the first equation to get:

4*a = 8 - b

Now we can replace it in the second equation:

4 = (8 - b) +  2*b

4 = 8 + b

4 - 8 = b

-4 = b

Now that we know the value of b, we can use

4*a  = 8 - b

4*a = 8 + 4 = 12

a = 12/4 = 3

Then the equation of the parabola is:

y = 3*x^2  - 4*x
