Answer:  First three terms are 1/25, 1/5, and 1 in that order.

===========================================================

Explanation:

The fifth term is 25, which makes the fourth term to be 25*(1/5) = 5. We multiply any term by the reciprocal of the common ratio to move back to the previous term.

The third term is 5*(1/5) = 1. The second term is 1*(1/5) = 1/5. The first term is (1/5)*(1/5) = 1/25

Therefore, the first five terms are:

1/25, 1/5, 1, 5, 25

As we move from left to right, we multiply each term by 5. Going in reverse, we multiply by 1/5.

A company charges $211.25 for 5 trees and 15 shrubs. The company charges $15.25 more for a tree than a shrub. How much does each
dusya [7]
(a+15.25)=x cost of each tree
(a•15)=110 cost of all the shrub
(x•5)= 101.25 cost of all trees
110+101.25= 211.25

equatiin all together
[(a+15.25)×5]+(a×15)=211.25

According to the table, Tasha initially had blank dollars before purchasing songs, and the cost of each song was blank dollars
melomori [17]

Total money before purchasing = $30

Cost of each song = $1.20

Solution:

According to the table,

No. of songs    Amount

        2                 27.60

        3                 26.40

        4                 25.20

Difference between amount she have after bought 3 songs to 2 songs:

27.60 – 26.40 = 1.20

Difference between amount she have after bought 4 songs to 3 songs:

26.40 – 25.20 = 1.20

So, the cost of each song = $1.20

Amount of money she had after purchasing one song = $27.60 + $1.20

                                                                                          = $28.80

Tasha initially had before purchasing songs = $28.80 + $1.20

                                                                         = $30

Hence Tasha initially had $30 before purchasing songs and the cost of each song was $1.20.

Which inequality represents all values of X for which the product below is defined
balandron [24]

The domain for which the function is defined is given by:

D. x \geq 4.

<h3>What is the domain of a function?</h3>

The domain of a function is the set that contains all possible input values for the function.

A square root is only defined for non-negative values, hence:

  • x - 4 \geq 0 \rightarrow x \geq 4.
  • x + 1 \geq 0 \rightarrow x \geq -1.

The intersection of these two domains is x \geq 4, hence option D is correct.
