The value of savings account can be modeled by the function S(x) = 5, 000 * (1.025) ^ (0.7x) x is the number of years 1980. What
garik1379 [7]

Answer:

The approximate growth rate of the savings account is 2.5%

Step-by-step explanation:

Given the the function S(x) = 5, 000 * (1.025) ^ (0.7x)

From the function, we can see that part:  (1.025). It presents for the growth factor or rate with the formula as:

(1 + r)  where r is rate

So we have:

(1 + r) = 1.025

<=> r = 1.025  -1

<=> r = 0.025

In pecentage, we have the rare: 0.025 *100% = 2.5%

So the approximate growth rate of the savings account is 2.5%

Estimate the difference 8 7/12 - 4 7/8 - 4/10
Gnesinka [82]
When you are told to estimate, you should be able to do the problem in your head.
8 7/12 is close to 8 1/2
4 7/8 is very nearly 5
4/10 is very nearly 1/2

8 1/2 - 5 - 1/2 First of all you can take the 1/2 away from 8 1/2
8 1/2 - 1/2 = 8
Now take away the 5


8 - 5 = 3

So the answer is very nearly
3 <<<<< answer.

Just for fun, I'll get the exact answer. Don't hand this one  in. It is 3 37/120
You learn to estimate because you are trying to guess whether or not you've entered everything correctly into your calculator. When writing a test, this is a very handy skill to have developed.

Mario tried to solve an equation step by step.
Zarrin [17]

Answer:

Step 2

Step-by-step explanation:

Mario made a mistake in Step 2 when substracting \frac{1}{3} from \frac{4}{3}. When substracting his result ended up being \frac{2}{3} but it is actually....

\frac{4}{3} - \frac{1}{3} = \frac{4-1}{3} = \frac{3}{3} = 1

so the right answer is q = 1

What is the solution for the system of equations? Use the substitution method to solve. Y=5−3x5x−4y=−3 Enter your answer by fill
Taya2010 [7]

Using the substitution method to solve the linear system the value of x and y is 1 and 2 respectively.

<h3>What is the linear system?</h3>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width.

Given

The equations are shown below.

y = 5 - 3x .....1

5x - 4y = -3 .....2

Substitute equation 1 in equation 2. Then

\begin{aligned} 5x - 4(5-3x) &= -3\\\\5x - 20 + 12x &= -3\\\\17x &= -3 +20 \\\\17x  &= 17\\\\x &= 1\end{aligned}

Then substitute the value of x in equation 1.

y = 5- 3x\\\\y = 5-3*1\\\\y = 2

Thus, the value of x and y is 1 and 2 respectively.

More about the linear system link is given below.
