Environmentalists estimate an annual population decrease of giraffes in the wild of 3.5% due to development. This can be modeled by the function p(x) = 140,000(0.965)^x, where x is the number of years of tracking the populations. Conservationists have developed a sanctuary that has shown the ability to increase the population by 0.85% per year. The increase can be modeled by the function S(p) = p(1.0085)^x.
Which function represents S(p(x)), rounded to the nearest ten thousandth?
A. S(p(x)) = 135,100(0.9732)^x
B. S(p(x)) = 135,100(1.9735)^x
C. S(p(x)) = 140,000(0.9732)^x
D. S(p(x)) = 140,000(1.9735)^x
Answer:
S(p(x)) = 140,000(0.9732)^x
Step-by-step explanation:
Given the population functions:
ENVIRONMENTALIST: decline by 3.5% annually
p(x) = 140,000(0.965)^x
CONSERVATIONISTS: Increase by 0.85% annually ;
S(p) = p(1.0085)^x
Formulate S(p(x)) rounded to the nearest ten thousand
p(x) = 140,000(0.965)^x
S(p) = p(1.0085)^x
S(p(x)) = p(1.0085)^x
Where p(x) = 140,000(0.965)^x
S(p(x)) = 140,000(0.965)^x(1.0085)^x
S(p(x)) = 140,000(0.9732025)^x
S(p(x)) = 140,000(0.9732)^x

You go to the store and notice the people standing in line. 7 adults and 4 children. If this ratio stays the same and there 55 people in the store. how many would be children?
Answer:
20
Step-by-step explanation:
7+4=11
11*5= 55
4*5=20 :)
The number of children and adults will be 35 and 20, respectively.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
You go into the store and observe the folks in queue. There are 7 adults and 4 children. If this ratio remains constant and there are 55 people in the store.
7x / 4x = constant
Then the equation is given below.
7x + 4x = 55
11x = 55
x = 11
Then the number of adults is given as,
7x = 7 (5) = 35
Then the number of children is given as,
4x = 4 (5) = 20
The number of children and adults will be 35 and 20, respectively.
More about the ratio and the proportion link is given below.

Anne owns a used car lot and in order to get cars to sell, she buys used cars at an
auction place. It costs $200 to attend the auction and she buys used cars at
$2,000 each. Last Tuesday, she purchased 10 cars. Which of the following
functions correctly represents this situation in function notation?
f(x) = 10x + 200
f(x) = 200x + 2,000
f(x) = 2,000x + 10
f(x) = 2,000x + 200
Answer:
It would be 2,000x+200
Step-by-step explanation:
okay it costs $200 to attend so that's a cost you are going to have to pay regardless. The $2,000 depends on how many cars you buy. So it would be 2,000 (times how ever many cars you buy) plus the $200.

Answer:
58
Step-by-step explanation:
Step-by-step explanation:
AD=DC
So angle A is equal to angle C
Let Angle A be x
And angle ABD is equal to 90 degree
So in triangle ADB
90+32+x=180 (angle sum property)
x=180-122
x=58
As angle A and angle C are equal
So angle C=58 degrees
