∞ ∑ (3+na)

n=1

Identify the following series as arithmetic, geometric, both, or neither.

I think or maybe if you want me to say this the given series is a geometric one with fert term, -3 and common ratio -1

Step-by-step explanation:

I am so sorry if this is not what you meant I apologize

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
