Q2. a) Is the equality √a^4 = a valid for all values of a? Explain.

allochka39001 [22]

Answer:

The equality is only true for $a = 0\ and\ 1$ , not for all values

Step-by-step explanation:

Given

$(\sqrt a)^4 = a$

Required

Determine if it is valid

$(\sqrt a)^4 = a$

Evaluate the exponent

$(a^\frac{1}{2})^4 = a$

$a^\frac{1*4}{2} = a$

$a^2 = a$

Rewrite as:

$a^2 - a = 0$

Factorize

$a(a- 1) = 0$

$a =0\ or\ a - 1 = 0$

$a =0\ or\ a = 1$

The equality is only true for  $a = 0\ and\ 1$ , not for all values

George had $6,000 in a savings account earning simple interest at a rate of 5% per year. At the end of the year, George paid 25%

Readme [11.4K]

Answer:

$225

Step-by-step explanation:

Given that:

Principal = $6,000

Interest rate = 5%

Time = 1 year

Taxes paid = 25% on the interest earned

To find:

Money earned after paying taxes ?

Solution:

First of all, let us calculate the total interest earned:

Formula for Simple Interest is given as:

$SI =\dfrac{PRT}{100}$

Where P is the principal

R is the rate of interest

T is the time taken

Putting the given values:

$SI =\dfrac{6000 \times 5\times 1}{100} =\$300$

Now, it is given that 25% of the interest earned is given as taxes.

Taxes paid = 25% of $300

$\Rightarrow \dfrac{25}{100} \times 300 =\$75$

Therefore, the money earned = Interest earned - Taxes paid

The money earned = $300 - $75 = $225

In a list of 7 consecutive integers, the sum of the first and last is 518. find the largest.

solong [7]

Answer:

262

Step-by-step explanation:

If x is the first integer, then x+1 is the second, x+2 is the third, and so on. Meaning the 7th term in the list is x+6.

x + x + 6 = 518

2x = 512

x = 256

The first integer is 256, so the last integer is 262.
