Answer:

Answer:

=   - ( \frac{1}{3}  \times  \frac{1}{3}  \times   \frac{1}{3}  \times  \frac{1}{3} )

Step-by-step explanation:

-  {(3)}^{ - 4}   =  \\  - ( { 3}^{ - 4}  )=  \\  -  (\frac{1}{ {3}^{4} } )=   - ( \frac{1}{3}  \times  \frac{1}{3}  \times   \frac{1}{3}  \times  \frac{1}{3} )=  -  \frac{1}{81}

10. The fifth term of an arithmetic sequence is 11 and the tenth term is 41. What is the first term? ​
9966 [12]

a_{5}=a+4d=11\\a_{10}=a+9d=41

Solve the above equations,

a_{10}-a_{5}=41-11\\a+9d-a-4d=30\\5d=30\\d=6\\a=11-24=-13

First term is -13.

Which of the following is the graph of (x-2)^2 + (y+1)^2 = 9? (Brainly doesn't seem to want to let me put up pictures. Sorry guy
forsale [732]
If you want to cheat, paste the formula in Wolfram Alpha. However, this one is not that difficult. From the fact that x and y are squared you can infer that this is a circle. The 9 reveals that the radius r^2 is 9, so radius is 3.

The (x-2) tells us that the circle is shifted to the right by 2. Likewise, y+1 shifts it down by one. So the center is at (2,-1). If the equation would be x^2 + y^2 = 9, you'd have a circle exactly on the origin.

Hopefully this helps you break down the equation and pick the right picture!

You bought a video game for
Temka [501]

Answer: $0

Step-by-step explanation:

every six months means the game loses 25%*2 per year = 50%

2 years would be 50%*2 = 100%

Therefore, if the game loses 100% of its value in 2 years, it will be free.

The ratio of Rogers age to his sons is 7:3. If the sum of their ages are 60 how old is Rogers son
Nimfa-mama [501]

Answer:24

Step-by-step explanation:

Sum of their ages is 60 yr. As such

7x + 3x = 60

10x = 60

x = 60 / 10

x = 6

The rationale is 6, therefore

Father's age is 7x = 7 × 6= 42 years

Son's age is 3x = 3 × 6 = 18 years

Difference in their ages

42 - 18 = 24 years
