what is (-3)^-5 with a positive exponent​

Answers

Answer: 1/-3^5

A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ. For example, 2⁻⁴ = 1 / (2⁴) = 1/16.

Answer:

x = 30.5

Step-by-step explanation:

4x + 2 = 124 ( subtract 2 from both sides )

4x = 122 ( divide both sides by 4 )

x = 30.5

The difference of the two numbers is 1.Their sum is 23.find the numbers

Answers

Answer:

11 and 12

Step-by-step explanation:

The two numbers will be called x and y. The sum of x and y is 23 and the difference is 1.

x + y = 23  

x - y = 1

Add the equations together

x + y + x - y = 23 + 1

2x = 24

x = 12

y = x - 1

y = 11

A line segment can be drawn from each vertex of a polygon to every other vertex, forming the sides and
diagonals of the polygon. A square, for example, has 4 sides and 2 diagonals. Using combinations, write
an expression that would give you the total number of sides and diagonals for a polygon with
sides.

Answers

Answer:

n(n - 3)/2

Step-by-step explanation:

We are told that;

A square has 4 sides and 2 diagonals.

Now, a pentagon will have 5 sides and 5 diagonals

A hexagonal when drawn will have 6 sides and 9 diagonals

Thus, we see that;

When n = 4, d = 2

When n = 5, d = 5

When n = 6, d = 9

Using combination, we will find number of pairs of 2 vertices that can possibly be formed from n-vertices. Thereafter we will subtract n from that since it's neighboring vertices can't combine with the current one.

Thus, we have;

C(n, 2) - n

This gives s;

(n(n-1)/2) - n

Simplifying this gives;

(n(n - 1) - 2n)/2

>> (n² - n - 2n)/2

>> (n² - 3n)/2

>> n(n - 3)/2

During testing, the experimental probability of completing a new game with a perfect score was found to be StartFraction 1 over 500 EndFraction. If 1,000,000 people buy and play the game when it is released, how many players will complete the game with a perfect score?

Answers

Given: 1/500 and 1,000,000

Multiply 1/500 & 1,000,000

1/500 * 1,000,000 = 2000

Thus, 2000 people are likely to complete the game with a perfect score

Olivia download music for $1.89 per song. She has a credit on her account for $3. Which expression could be used to represent the cost of the music if Olivia downloads m songs?

Answers

Answer:

Answer 3 (1.89m - 3)

Step-by-step explanation:

Since we know that the price per song is $1.89, that is going to be the part of the equation that goes with the variable.

Since she has a 3 dollar credit, this will reduce the cost of whatever amount of songs she is buying by 3 dollars, which means the second part of the equation is -3. You have your answer, 1.89m - 3.

Ellie is interested in getting a new phone. One phone company, phone 1 charges a monthly fee of 6$. They also charge 0.10$ per minute. Another company, phone 2, charges 5$ for a monthly fee and 0.25$ per minute. Write an equation for the total cost of each phone bill, where y is the total cost and x is the total number of minutes on the phone. Which company will allow Ellie to talk the longest is she only wants to spend 22$ a month

Answers

Answer:

Phone 1 will allow Ellie to talk the longest

Step-by-step explanation:

Phone 1:

     (0.10x) + 6 = y

(0.10x) + 6 - 6 = 22 - 6

     0.10/0.10x = 16/0.10

                    x = 160 minutes

Phone 2:

      (0.25x) + 5 = y

(0.25x) + 5 - 5  = 22 - 5

     0.25/0.25x = 17/0.25

                      x = 68 minutes

James adds vitamin drops to his fish tank to keep his fish healthy. If James
follows the instructions on the bottle of vitamins, how many capfuls should he add
to his 450-litre tank? (4 marks)
• 2 drops per 5 litres
of water
• 1 capful = 40 drops

Answers

Step-by-step explanation:

350/5=70 liters X 2 drops for every 5 liters=140 drops needed for the whole tank.

Since 1 cupful contains 40 drops, the we have this:

140 drops needed for the full tank/40 drops contained in one cup, or,

140/40=3 1/2=3.5 number of cupfuls needed for the full tank.
