Answer:

Point (2, 20) does not lie on the given curve.

Step-by-step explanation:

Let us see explanation:

$f(x) = 2. \: {5}^{x} \\ \\ \therefore \: f(x) \: at \: x = 2 \\ f(2) = 2. {5}^{2} = 2.25 = 50 \\ \\ hence \: at \: x = 2 \: \: f(x) = 50 \\ \therefore \:point (2 \: \: 20) \: does \: not \: lie \: on \: the \: \\ \: \: \: \: \: curve.$

A math textbook is 1 1/4 in. thick. how much shelf space is needed for 30 copies of the book?

inysia [295]

Hello!

You have to multiply 1 1/4 by 30 because each math book is 1 1/4 in. thick, and 30 books is 1 1/4 by 30. First change 30 and 1 1/4 to an improper fraction.

$\frac{30}{1} \times \frac{5}{4} = \frac{150}{4} = 37 \frac{1}{2}$

Factor the given expression. 64^3-343

Mashcka [7]

63³-343 = 261801

Factor the following integer:

261'801

The sum of the digits of 261801 is 2 + 6 + 1 + 8 + 0 + 1 = 18, which is divisible by 9. This means 261801 is too.

261801 = 9×29089:

261801 = 9×29089

9 = 3^2:

261801 = 3^2×29089

Because 29089 is odd, only test odd numbers for divisibility.

29089 is not divisible by 3, 5, 7, 9, 11, 13, 15 or 17.

29089 = 19×1531 which means 29089 is divisible by 19:

261801 = 3^2×19×1531

3 is prime:

261801 = 3^2×19×1531

Because 19 is odd, only test odd numbers for divisibility.

19 is not divisible by 3.

Since 19 is not divisible by any integer up to 4, it is prime:

261801 = 3^2×19×1531

Because 1531 is odd, only test odd numbers for divisibility.

1531 is not divisible by 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37 or 39.

Since 1531 is not divisible by any integer up to 39, it is prime:

261801 = 3^2×19×1531

There are 2 copies of 3, 1 copy of 19 and 1 copy of 1531 in the product:

Answer: 261801 = 3^2×19×1531
