Given the two expressions shown below:

kobusy [5.1K]

<h2>Answer: A. Both are rational.</h2>

Step-by-step explanation:

Although both expressions have square roots, the result of each square root is an integer, which can be expressed as a fraction.

In this sense:

Rational numbers are all numbers that can be represented as the quotient (division) of two integer numbers. This means they can be represented as a fraction in which the denominator is nonzero.

If we solve both expressions, we will be able to see that the result is an integer that can be expressed as a fraction with two integers:

$\sqrt{4} + \sqrt{25}=2 + 5= 7$ The result is an integer

$7=\frac{7}{1}$

$\sqrt{4} + \sqrt{9}= 2 + 3=5$ The result is an integer

$5=\frac{5}{1}$

Is the square root of 225 a rational number?

MArishka [77]

Step-by-step explanation:

$\text{The principal square root}:\\\\\sqrt{a}=b\iff a^2=b\ \text{for}\ a\geq0\ \text{and}\ b\geq0.\\\\\text{The square root:}\\\\\sqrt{a}=b\iff b^2=a\ \text{for}\ a\geq0\\===================$

$\text{If you want the principal square root (arithmetic square root):}\\\\\sqrt{225}=15\ \text{because}\ 15^2=225\\\\\text{If you want square root (algebraic square root):}\\\\\sqrt{225}=\pm15\ \text{because}\ (-15)^2=225\ \text{and}\ 15^2=225$

The principal amount, $5500, earns 3.75% interest compounded continuously.

Eva8 [605]

Answer:

The function that represents the value of the account at any time, t

$\:\:A=Pe^{rt}$

The total amount accrued, principal plus interest, from compound interest on an original principal of $ 5,500.00 at a rate of 3.75% per year compounded continuously over 6 years is $ 6,887.77.

Step-by-step explanation:

a. Write the function that represents the value of the account at any time, t.

The function that represents the value of the account at any time, t

$\:\:A=Pe^{rt}$

where

A represents the Future Value

P represents the Principle (Initial Value)

r represents the Interest rate

t represents the time

b) What will the value be after 6 years?

Given

The principal amount P = $5500

Annual Rate r = 3.75% = 3.75/100 = 0.0375

Time Period t = 6 years

To Determine:

The total amount A = ?

Using the formula

$\:\:A=Pe^{rt}$

substituting the values

$A\:=\:5500\left(2.71828\right)^{\left(0.0375\right)\left(6\right)}$

$A=5500\cdot \:2.71828^{0.225}$

$A = $ 6,887.77$ $

Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 5,500.00 at a rate of 3.75% per year compounded continuously over 6 years is $ 6,887.77.
