Answer:

78. t=8.66yrs

79. r=23.10%

80. r=11.0975%

Step-by-step explanation:

78. Given the initial deposit is $1,000 and the 8% compounded continuously. The doubling time can be calculated using the formula;

$A=Pe^{it}$

Given that A=2P, we substitute in the equation to solve for t:

$A=Pe^{rt}\\\\2P=Pe^{rt}\\\\2=e^{0.08t}\\\\0.08t=\ In 2\\\\t=8.66\ years$

Hence, it takes 8.66 years for $1,000 to double in value.

79.

Given the initial deposit is $1,000 and the r% compounded continuously.

-The doubling rate can be calculated using the formula;

$A=Pe^{rt}$

#We substitute our values in the equation to solve for r:

$A=Pe^{rt}\\\\A=2P, t=3\\\\\therefore\\\\2P=Pe^{3r}\\\\2=e^{3r}\\\\r=\frac{In \ 2}{3}\\\\=0.23105\approx 23.10\%$

Hence, the deposit will double in 3 years at a rate of 23.10%

80.

Given the initial deposit is $30,000 and the future value is $2,540,689.

-Also, given t=40yrs, the rate of growth for continuous compounding is calculated as:

$A=Pe^{rt}, \ \ \ r=r, t=40yrs\\\\2540689=30000e^{40r}\\\\\frac{2540689}{30000}=e^{40r}\\\\r=\frac{In \ (2540689/30000)}{40}\\\\\\=0.110975=11.0975\%$

Hence, the deposit will grow at a rate of approximately 11.0975%

Why do some numerical expressions contain parentheses

Elden [556K]

The most basic and common reason to use parentheses, brackets, and braces is to control the order of operations.

<h3>What are parentheses?</h3>

In mathematics, parenthesis is used to arrange numbers in the sequence of operations, clarify numbers, and denote multiplication.

Suppose you have an expression as:-

E = { ( 5-2 )8} 6

In this case, you would calculate 5 minus 2 first (parentheses), then multiply by 8 (brackets), then complete the part inside the curly braces, and finally multiply by 6.

Therefore the most basic and common reason to use parentheses, brackets, and braces is to control the order of operations.

Which ordered pair makes both inequalities true?

Digiron [165]

For a
0 > -3(1) + 3 i.e. 0 > 0 (not true)
For b
1 > -3(-1) + 3 i.e. 1 > 6 (not true)
For c
2 > -3(2) + 3 i.e. 2 > -3 (true)
2 > 2(2) - 2 i.e. 2 > 2 (not true)
For d
3 > -3(0) + 3 i.e. 3 > 3 (not true)

Therefore, none of the ordered pairs makes both inequalities correct.

Frank reasoned that in the number 0.555, the value of the 5 in the thousands place is ten times as great as the 5 in the hundred

Gnom [1K]

The given number is 0.555 which can be written as

$0+ \frac{1}{10}*5 + \frac{1}{100}* 5+ \frac{1}{1000} * 5$

As we see that after decimal, every next digit is 1/10 times of the current digit .

Therefore the statement , " the value of the 5 in the thousands place is ten times as great as the 5 in the hundredth place " is not correct .

What is 100×100?<br><br> can someone help me

Hunter-Best [27]

100 times 100
When you want to multiply 100 by 100, count up all the zeros first.
There are 2 zeros in one 100 and 4 zeros in two 100's.
Since there are 4 zeros, that means 100 • 100 is a 1 followed by 4 zeros.
This means 100 • 100 = 10,000

100 multiplied by 100 is 10,000 (ten thousand)

Hope this helps!
