. City workers recorded the number of squirrels in a park over a period of time. At the first count, there were 15 pairs
1 answer:
Answer:
Exponential
P(X) = P_0 (2)^{2x}
Step-by-step explanation:
Given that at the first count, there were 15 pairs
of male and female squirrels (30 squirrels total). After 6 months, the city workers recorded a total of 60 squirrels,
and after a year, there were 120.
i.e. every 6 months population of squirrel is doubling.
a) Function is exponential since every time of 6 months population is doubled
b) The function that represents the population of squirrels recorded over x number of years.
We know that every 1/2 year it doubles. Hence initially if P0 is started with in 1/2 year it would be 2P0 and in 1 year it would be 4P0 and so on.
In other words, the model would be
where x = no of years

Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are scalene, acute, obtuse, isosceles, equilateral and right angled triangle.
A right angled triangle is a triangle with one angle equal to 90 degrees. The longest side of a right angled triangle is known as the hypotenuse. Trigonometric identities is used to show the relationship between the angles and sides of a right angled triangle, i.e.:
sinθ = opposite/hypotenuse; cosθ = adjacent / hypotenuse; tanθ = opposite / adjacent
From the image:
let the distance from jack to the base of the building be x, hence:
tan60 = x / 60
x = 60 * tan60 = 104 ft.
Answer:
C
Step-by-step explanation:
The secant- tangent angle MLK is half the difference of the intercepted arcs, that is
(KN - KM) = 70° ( multiply both sides by 2 to clear the fraction )
KN - KM = 140°
KN - 61° = 140° ( add 61° to both sides )
KN = 201° → C
