\sqrt[5]{32x^5y^{10}z^{15}}=\sqrt[5]{32}\cdot\sqrt[5]{x^5}\cdot\sqrt[5]{(y^2)^5}\cdot\sqrt[5]{(z^3)^5}=2xy^2z^3

Used:

(a^n)^m=a^{n\cdot m}\\\\\sqrt[n]{a^n}=a

Answer: b- 2xy^2z^3

Answer:  Option 'b' is correct.

Step-by-step explanation:

Since we have given that

^5\sqrt{32x^5y^{10}z^{15}}

We need to find the expression which would be equivalent to the above expression.

As we know that

32=2⁵

So, it becomes,

^5\sqrt{2^5x^5y^{10}z^{15}}\\\\=(2^5)^{\frac{1}{5}}\times (x^5)^{\frac{1}{5}}\times (y^{10}){\frac{1}{5}}\times (z^{15})^{\frac{1}{5}}\\\\=2\times x\times y^2\times z^3\\\\=2xy^2z^3

Hence, Option 'b' is correct.

babymother [125]

Answer: price of the watch before the discount is £23.5825

Step-by-step explanation:

Let x represent the original price of the watch.

Jason went shopping he bought a watch and a pair of trainers for a total price of £53.55. This price includes 15% loyalty discount. The value of the discount is

15/100 × 53.55 = 8.0325

This means that the original cost of both items is

53.55 + 8.0325 = 61.5825

Before the discounts, the trainers were priced at £38. Therefore,

38 + x = 61.5825

x = 61.5825 - 38

x = 23.5825

Find sin theta if cot theta = -2 and cos theta < 0
Katarina [22]

cot(<em>θ</em>) = cos(<em>θ</em>)/sin(<em>θ</em>)

So if both cot(<em>θ</em>) and cos(<em>θ</em>) are negative, that means sin(<em>θ</em>) must be positive.

Recall that

cot²(<em>θ</em>) + 1 = csc²(<em>θ</em>) = 1/sin²(<em>θ</em>)

so that

sin²(<em>θ</em>) = 1/(cot²(<em>θ</em>) + 1)

sin(<em>θ</em>) = 1 / √(cot²(<em>θ</em>) + 1)

Plug in cot(<em>θ</em>) = -2 and solve for sin(<em>θ</em>) :

sin(<em>θ</em>) = 1 / √((-2)² + 1)

sin(<em>θ</em>) = 1/√(5)

6 were Elm Trees

The fraction of trees that were Elm trees are 6 / 25

Converting this fraction to percentage = 6 / 25 x 100 = 24%

The question doesn't provide any information on if she climbed any trees

The solution to the system of equation below is (−2, −1). 2x − 3y = −1 11x − 9y = −13 When the first equation is multiplied by −
Natali [406]
We are given with two equations 2x − 3y = −1 and <span>11x − 9y = −13. The problem says that when the first equation is multiplied by -3 which results to -6x + 9y = 3, the sum of the resulting equation and the second one is equal to 5x = -10. We verify this: -6x + 11x = 5x while -9 y and 9 y cancels out. 3+-13 equals -10. Hence the total is really 5x = - 10.</span>
