Answer:

P(t) = 3810(1.0035)^{t}

Step-by-step explanation:

Given:

P(t) = 3810(1.0005)^{7t}             -----(1)

Simplifying (1.0005)^{7t}

From Law of indices, x^{mn} = (x^{m})^{n}

(1.0005)^{7t} = (1.0005^{7})^{t}

When 1.0005 is raised to the 7th power, it is approximately 1.0035.

Substituting (1.0005)^{7t} = (1.0035)^{t} into equation(1)

P(t) = 3810(1.0035)^{t}

Plzz help me im going to most more like this because im not understanding it
lisov135 [29]
Hi there!

In order to solve, you can use substitution. This means that you use one equation and solve for one variable, then use that one equation and plug it into the other equation. Here's how we'd do it:

WORK:
x = 12 - y (since x is already solved for, we'll use that to plug into the other given equation.
2(12 - y) + 3y = 29 (using substitution)
24 - 2y + 3y = 29
24 + y = 29
y = 5
Plug the value of y back into the first equation
x = 12 - 5
x = 7

ANSWER:
A - x = 7, y = 5

It seems as though you're having some trouble with these questions, PLEASE MESSAGE ME!! I'd be more than happy to help you work through as many problems as you need until you get the hang of it (plus, it doesn't cost you any points!)

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

A two-story building measures 21 feet from the ground.Ascale model shows the building to be 3 inches tall. How many inches would
jasenka [17]

Answer: 12\ inches

Step-by-step explanation:

Let be "x" the height inches (in the model) of a 84 foot building.

According to the information provided in the exercise, we know that the height of a two-story building is 21 feet and in the scale model its height is 3 inches.

Knowing this, we can set up the following proportion:

\frac{3}{21}=\frac{x}{84}

The final step is to solve for "x" in order to calculate its value. We get that this is:

\frac{3}{21}=\frac{x}{84}\\\\(84)(\frac{3}{21})=x\\\\x=12

Therefore,  an 84 foot building will be 12 inches tall in the model.
