2 numbers that add up to 100: 71+29=100

2 numbers which differ by 46: 63-17=46

the first term in a geometric series is 64 and the common ratio is 0.75. Find the sum of the first 4 terms in a series.

Rufina [12.5K]

u0 = 64 with u(n+1) = un *0.75

u3 = 64 *0.75^3 = 27

sum is : 64 * ( 0.75^4 -1) / 0.75-1 = 175

manual proof : 64 + 48+36+27 = 175

Explain why the mapping diagram below represents a function.

tiny-mole [99]

Answer:

Because there is only one out put for each domain this mapping diagram is a function.

Step-by-step explanation:

Two sets are involved. There is a directional property, the relation is defined from one set called the domain on to another set called the codomain. A function is a relation that has exactly one output for each input in the domain.
