Joshua currently does a total of 8 pushups each day. He plans to increase the number of pushups he does each day by 2 pushups un

Maslowich

Answer:

x=12

Step-by-step explanation:

Let y equal number of pushups a day. When x = 1, y = 8. When x = 2, y = 10. 10 is a factor of 30. Multiply y by 3. However, since x increases by 1 when y increases by 2, multiply x by 6 (2*3). That equals 12. Therefore, when x = 12, y = 30.

The sum of the first 6 terms of a geometric series is 15,624 and the common ratio is 5. What is the first term of series?

Shalnov [3]

Answer:

Step-by-step explanation:

Suppose

S = sum of the six terms
a1 = the first term

$\left. { S = a _ { 1 } \frac { 1 - 5 ^ { 6 } } { 1 - 5 } } \\\\ { \Leftrightarrow S = \frac { a _ { 1 } } { 4 } ( 5 ^ { 6 } - 1 ) } \\\\ { \Leftrightarrow a _ { 1 } = \frac { 4 S } { 5 ^ { 6 } - 1 } } \right.$

then a1 = (4×15 624)÷(5^(6)-1)

= 4
