Write a power that has a value greater than 340 and less 345

valina [46]

For this case we must write a power between (340,345)

We chose 343.

We divide the number until we get an exact division:

$\frac {343} {2} = 171.5\\\frac {343} {3} = 114.3\\\frac {343} {4} = 85.75\\\frac {343} {5} = 68.6\\\frac {343} {6} = 57.17\\\frac {343} {7} = 49\\$

So we have:

$7 ^ n = 343\\n = 3$

So, the power is:

$7 ^ 3 = 7 * 7 * 7 = 49 * 3 = 343$

ANswer:

$7 ^ 3 = 7 * 7 * 7 = 49 * 3 = 343$

Juan invest $3700 in a simple interest account at a rate of 4% for 15 years

OleMash [197]

Question:

Juan Invest $3700 In A Simple Interest Account At A Rate Of 4% For 15 Years. How Much Money Will Be In The Account After 15 Years?

Answer:

There will be $ 5920 in account after 15 years

Solution:

The simple interest is given by formula:

$S.I = \frac{p \times n \times r }{100}$

Where,

p is the principal

n is number of years

r is rate of interest

From given,

p = 3700

r = 4 %

t = 15 years

Therefore,

$S.I = \frac{3700 \times 4 \times 15 }{100}\\\\S.I = 37 \times 4 \times 15\\\\S.I = 2220$

How Much Money Will Be In The Account After 15 Years?

Total money = principal + simple interest

Total money = 3700 + 2220

Total money = 5920

Thus there will be $ 5920 in account after 15 years

a child starts a piggy bank with $2. each day, the child receives 25 cents at the end of the day and puts it in the bank. if A r

Troyanec [42]

For a given function f(x), the domain is the set of possible values of x that we can use and the range is the set of the possible values of f(x).

For both points we will find that the answer is:

"We only can evaluate the function with integer values of d."

a) Here we have the function:

A(d) = 2 + 0.25*d

The first thing we want to answer is:

"explain why the domain does not contain the value d=2.5 "

We know that at the end of each day the kids get's the $0.25, so at d= 2.5 there two days and a half, and because only 2 nights passed, at this moment the kid only got the money two times.

So for d = 2.1

d = 2.5

d = 2.7

etc

We would get the exact same total money, thus we only can evaluate the function with integer values of d.

b) Why the range does not include the value A = $3.10?

Remember that d can only be an integer number.

Now let's solve:

A(d) = 3.10 = 2 + 0.25*d

3.10 - 2 = 0.25*d

1.10 = 0.25*d

1.10/0.25 = d = 4.4

So we only can get A = $3.10 if d = 4.4, and remember that d only can be a whole number, this is why the range does not include the value $3.10

Which expressions simplify to a rational answer? Select each correct answer. 29√⋅4√ 3√⋅16−−√ 73⋅−√3√ 5√⋅5√

PolarNik [594]

Answer:

The correct options are 1, 3 and 4.

Step-by-step explanation:

We need to find the expressions whose simplified form is a rational number.

Rational number: If a number is defined in the form of p/q where p and q are integers and q≠0, then it is called a rational number.

For example: 0,2, 4.3 etc.

Irrational number: If a number can not defined in the form of p/q, where p and q are integers and q≠0, then it is called an irrational number.

First expression is

$2\sqrt{9}\cdot \sqrt{4}=2(3)\cdot (2)\Rightarrow 6\cdot 2=12$

12 is a rational number.

Second expression is

$\sqrt{3}\cdot \sqrt{16}=\sqrt{3}\cdot 4\Rightarrow 4\sqrt{3}$

$4\sqrt{3}$ is an irrational number.

Third expression is

$7\sqrt{3}\cdot \sqrt{3}\Rightarrow 7\cdot 3=21$

21 is a rational number.

Fourth expression is

$\sqrt{5}\cdot \sqrt{5}=5$

5 is a rational number.

Therefore, the correct options are 1, 3 and 4.
