If x = - 2 and y = 3, what is the value of - x∧- y? the answer is 1/8. how? 
FinnZ [79.3K]
-x^{-y}

You have to know that every number to negative power is the inverse, for example:

3^{-1}=\frac{1}{3^1}

in this exercise we will make the same thing

when x=-2~~and~~y=3

-(-2)^{-3}

let's do the inverse

-\frac{1}{(-2)^3}

now (-2)^3=-8

-\frac{1}{-8}

doing the signal rule

\boxed{\boxed{\frac{1}{8}}}

What is the slope of each line? Line A: y = one-half x minus 4 Line B: y = 2 x minus 3 The slope of line A Equals one-half. The
Anestetic [448]

Answer:

The slope of line A equals one-half. The slope of line B equals 2.

Step-by-step explanation:

The equation of Line A is given by : y = \frac{1}{2} x - 4 ........... (1)

The equation of Line B is given by : y = 2x - 3 ............. (2)

Those two equations are in slope-intercept form i.e. y = mx + c, where m is the slope of the line.

Now, the slope of line A equals one-half. The slope of line B equals 2.

Therefore, option 1 will be correct. (Answer)

If you roll one die and flip one coin, what are all the possible outcomes?
Juliette [100K]

Answer: (1,T), (2,T), (3,T), (4, T), (5,T), (6,T)\\(1,H), (2,H), (3,H), (4, H), (5,H), (6,H)

Step-by-step explanation:

The total outcomes on a die = {1,2,3,4,5,6}=6

The total outcomes on a coin = {Tails  or Heads}=2

The number of possible outcomes =6\times2=12

If you roll one die and flip one coin, then the possible outcomes are:  

(1,T), (2,T), (3,T), (4, T), (5,T), (6,T)\\(1,H), (2,H), (3,H), (4, H), (5,H), (6,H)

Here T denotes for Tails and H denotes for heads.

Pythagorean theorem in 3D
kiruha [24]

Answer:

d = 6.997 or 7

Step-by-step explanation:

Use Pythagorean Theorem to find the diagonal of the end of the prism

2^2 + 3^2 = C^2     Simplify

4 + 9 = C^2             Add

13 = C^2                  Take the square root of both sides

3.6 = C

Now plug this into the Pythagorean Theorem equation for the diagonal of the whole prism.

3.6^2 + 6^2 = d^2     Simplify

12.96 + 36 = d^2       Add

48.96 = d^2               Take the square root of both sides

6.997 = d                   This can be rounded up to 7, if needed
