A perfect square is the square of an integer. Of the integers from 2 through 99, how many have at least one perfect square facto

N76 [4]

Answer:

Six numbers have perfect square factors

Step-by-step explanation:

The numbers with perfect square factors are those numbers that have perfect squares as one of the numbers that can divide them.

They include:

4 = 2 * 2

16 = 4 * 4

36 = 6 * 6

49 = 7 * 7

64 = 8 * 8

81 = 9* 9

These numbers above have perfect square factors because they are formed from integers that multiply themselves.

What is the average rate of change between f (1) and f (5) in the function f (x) = x2 - x - 6 ?

NISA [10]

Answer:

${ \tt{average = \frac{f(1) + f(5)}{2} }} \\ \\ = { \tt{ \frac{( {1}^{2} - 1 - 6) + ( {5}^{2} - 5 - 6) }{2} }} \\ = \frac{ - 6 + 14}{2} \\ \\ = { \tt{4}}$

A robot is expected to filter pollution out of at least 350 liters of air and water. It filters air at the rate of 50 liters per

s2008m [1.1K]

Answer:

$20W+50A\geq 350$

Step-by-step explanation:

we are given that A robot is expected to filter pollution out of at least 350 liters of air and water.

Also It filters air at the rate of 50 liters per minute, and it filters water at the rate of 20 liters per minute.

The inequality for number of minutes the robot should filter air (A) and water (W) to meet this expectations can be writte as follows:

$20W+50A\geq 350$

Hence the required inequality has been formulated.
