Answer:
(A)If x represents the number of songs she downloads then it is a variable because of the AMOUNT of songs she downloads.
Step-by-step explanation:
For example if we had f(x)=2 the equation would be c=4.99+.75(2)
.75*2=1.50+4.99=
(6.49 = c) cost per month if she downloads 2 songs
Answer:
- after week 7: 4374 pennies
- 486 pennies: after week 5
Step-by-step explanation:
The sequence values have a first term of 6 and a common ratio of 3, so can be described by the formula ...
an = 6·3^(n-1)
This can be rearranged to ...
an = 2·3^n
__
When n=7, the value is ...
a7 = 2·3^7 = 4374 . . . . pennies saved after 7 weeks
__
To find when there are 486 pennies saved, we can solve the equation ...
486 = 2·3^n
243 = 3^n
log(243) = n·log(3) . . . . . . . take the logarithm
log(243)/log(3) = n = 5 . . . . divide by the coefficient of n
Tabitha will have saved 486 pennies after 5 weeks.
Answer:
6 in * 4 in * 2 in
Step-by-step explanation:
Given the following data;
Volume of rectangular prism = 48 in³
To find its possible dimensions;
Volume of rectangular prism = length * breadth * height
48 = length * breadth * height
From the given options, option B is most likely to be its dimensions.
Where;
Length = 6 in
Breadth = 4 in
Height = 2 in
Substituting into the formula, we have;
48 in = 6 * 4 * 2
48 in = 48 in
