The population of a local species of dragonfly can be found using an infinite geometric series where a1 = 30 and the common rati o is two fifths. Write the sum in sigma notation and calculate the sum that will be the upper limit of this population.
1 answer:
Answer:
The answer is the summation of 30 times two fifth of the i minus 1 power from equation equals to 1, the sum is 50.
Explanation:
S = a ÷ (1-r)
S = 30 ÷ (1- (2÷5))
S = 50.
The sum is 50.
By sigma notation verifies 30.

Answer: A) y= -1/2x+5
Step-by-step explanation: If the line is perpendicular to the original, the new "m" (coefficient of x) has to be the negative reciprocal of the original "m"
y = 2 - x
y(-3) = 2 - (-3) = 2 + 3 = 5
y(0) = 2 - 0 = 2
y(5) = 2 - 5 = -3
