Answer: x^4

Step-by-step explanation:

1. Rewrite the expression in fraction form:

(3√x²)^6 = x^(2/3)^6

2 is the exponent, so when written in fraction form, it is the numerator. 3 is the index or root, so in fraction form it is the denominator.

2. Solve:

x^(2/3)^6 = x^(12/3) = x^4

Because the exponent 2/3 is raised to the power of 6, you can use the power rule, which basically just means that whenever an exponent is raised to an exponent, multiply them. So, 2/3 * 6 equals 12/3, and 12/3 equals 4, making your answer x^4.

The probability of drawing a quarter from a bag of coins is 4/5. What is the probability of drawing a coin that is not a quarter
elixir [45]
The sum of probability for an event happening and not happening must be equal to 1 because there is a 100% chance that one or the other will occur.

So the probability on not drawing a quarter:

P(!Q)=1-4/5

P(!Q)=5/5-4/5

P(!Q)=1/5

As a percentage:

p/100=1/5

p=100/5

p=20%

A student government organization is selling Christmas trees as a fundraiser. On Friday, they sold 5 noble fir trees and 3 dougl
Lana71 [14]

5 noble fir and 3 douglas fir = $ 420

12 noble fir and 9 douglas fir = $ 1080

Let noble fir be n,  and douglas fir be d.

5n + 3d = 420               ..............(i)

12n + 9d = 1080           ...............(ii)

Multiply equation (i)  by 3.

3*(5n + 3d) = 3*(420)

15n + 9d = 1260        .............(iii)

Equation (ii)  minus (iii)

(12n + 9d) - (15n + 9d) =  1080 - 1260

12n - 15n  + 9d - 9d = -180

-3n = -180

n = -180/-3 = 60

Substitute the value of n in (i)    5n + 3d = 420 

5*(60) + 3d = 420

300 + 3d  = 420
 
3d =  420 - 300 = 120

3d = 120

d = 120/3 = 40

Therefore Noble fir tree cost $60 while Douglas fir tree cost $40

TriangleABC has three sides with these lengths: AB=9, BC=40, and CA=41, What is the value of cos C?
Otrada [13]

Answer:

9² = 40² + 41² - 2(40)(41) cos(C)

81 = 1600 + 1681 - 3280 cos(C)

81 = 3281 - 3280 cos(C)

-3200 = -3280 cos(C)

cos(C) = 3200 / 3280

cos(C) = 40 / 41
