The function f(x) = 800(1.09)4x shows the growth due to interest that Jim earns on an investment. The steps to calculate an equi

valent function are shown below: [Step 1] f(x) = 800(1.09)4x
[Step 2] f(x) = 800(1.094)x
[Step 3] f(x) = 800(1.4116)x
[Step 4] f(x) = (1129.27)x

Ok, make sure you put the powers correctly. I know what you mean but someone else may not. So it's step 2. This is because the 4 doesn't mean add a digit.

Answer:

Step 1

Step-by-step explanation:

We are given that the function

f(x)=800(1.09)^4x shows the growth due to interest that Jim earns on an investment .

We are given that the steps to calculate an equivalent function .

We have to find the first incorrect step in calculation.

Step 1 f(x)=800(1.09)^4x

Step 2 f(x)=800(1.09\times1.09\times 1.09\times1.09)x

Step 3f(x)=800(1.4116)x

Step 4f(x)=(1,129.28) x

In second step Jim makes an mistake because he did  not  solved power correctly. He takes power as 0.004 and add to base then he gets 1.094. It is incorrect step of Jim.

So, Jim makes first mistake in step 1.

Answer: Step 1

What is the value of x in the equation 1.5(x + 4) - 3=4.5(x-2)
anyanavicka [17]
Hi there!

The Eqn. is :-

1.5 (x + 4) - 3 = 4.5 (x - 2)

1.5x + 6 - 3 = 4.5x - 9

Combining the like terms :-

1.5x - 4.5x = - 9 - 6 + 3

- 3x = - 15 + 3

- 3x = - 12

x = \dfrac {- 12}{- 3}

x = 4

Hence, the required answer is → x = 4

~ Hope it helps!

Adriano runs a website that helps writers write better stories. Every month, Adriano receives a subscription fee of $5 from each
tatuchka [14]
There aren't really any instructions for this, so I'll just go ahead and find the total amount of money for both months. The first month Adriano had 200 subscribers. 5 times 200 is 1000, so Adriano received $1000 that month. The second month 40 members joined, but 10 cancelled their subscription. Taking this into account, we'll just say that 30 members joined. 30 times 5 is 150, and 150 plus 1000 is 1150. Therefore, Adriano had to have received $1150 the second month.

I'm not entirely sure what the question was to begin with, but I hope this answers it!

True Or False?
natali 33 [55]
Electromagnets are devices that create a magnetic field through the application of electricity. Strong electromagnets are used to lift, move and drop heavy objects, such as vehicles. Electromagnets have advantages over permanent magnets. When the current is switched off, the electromagnet will lose its magnetism. The car will fall back to earth and we need that when we move cars in a junkyard. With a regular ( permanent ) magnet it would be much harder to do.
Answer: A. True
