Answer:
7
Step-by-step explanation:
This is the sum of the first three terms of a geometric sequence, where the first term is 4 and the common ratio is ½.
We can use a formula to find the sum, or, since there's only three terms, we can find the value of each term then add up the results.
4 · (½)¹⁻¹ = 4
4 · (½)²⁻¹ = 2
4 · (½)³⁻¹ = 1
4 + 2 + 1 = 7
Answer:
Step-by-step explanation:
4-x²+3 / x =
So, we need to think about this problem as either what we have to multiply x by to get the equation, and do long division
= 4x³- x +
Answer:
3.667
Step-by-step explanation:
30 miles per cm means divide distance by 30 or
110/30 = 3.667
