Mathematics
A gardener has three flowering shrubs and four nonflowering shrubs, where all shrubs are distinguishable from one another. He must plant these shrubs in a row using an alternating pattern, that is, a shrub must be of a different type from that on either side. How many ways can he plant these shrubs? If he has to plant these shrubs in a circle using the same pattern, how many ways can he plant this circle? Note that one nonflowering shrub will be left out at the end.

Ответ:
Either way you can in 144 ways.
Step-by-step explanation:
According to the statement we have 3 flowering shrubs and 3 flowerless shrubs.
We name them as follows:
S = flowering shrub
N = non flowering shrub
Now the only pattern in which these bushes can be arranged alternately as follows:
N-S-N-S-N-S-N
Therefore, to calculate the number of forms it would be:
Number of shapes: 4 * 3 * 3 * 2 * 2 * 1 * 1 = 144
Which means there are 144 ways.
Now if we organize them in a circle in the same way
again it would be the same number of ways to organize them: 144 ways.
This is because the nun's last blooming shrub is left outside.
Ответ:
Last option is correct i.e
The left side of the equation will result in a rational number, which could be a non-perfect square.
Step-by-step explanation:
Given that the Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse by the formula![a^2 + b^2 = c^2](/tpl/images/0338/5492/9bce6.png)
we have to tell if a is a rational number and b is a rational number, why could c be an irrational number.
As, a and b both are rational then their squares are also rational and the addition of two rational numbers are also rational.
Therefore, the only option which gives the c irrational is the square root of
.
Hence, last option is correct i.e
The left side of the equation will result in a rational number, which could be a non-perfect square.
