Answer:
Your answer should be D. $48,856.11
Step-by-step explanation:
This formula is for Compound Continuously.
[tex]A=P*e^{rt}[/tex]
P = 40,000
e = 2.71...
r = 2.5% = 0.025

Solve this trig identity step by step
The trigonometric identity (cos⁴θ - sin⁴θ)/(1 - tan⁴θ) = cos⁴θ
How to solve the trigonometric identity?
Since (cos⁴θ - sin⁴θ)/(1 - tan⁴θ) = [(cos²θ)² - (sin²θ)²]/[1 - (tan²θ)²]
Using the identity a² - b² = (a + b)(a - b), we have
(cos⁴θ - sin⁴θ)/(1 - tan⁴θ) = [(cos²θ)² - (sin²θ)²]/[1 - (tan²θ)²]
= (cos²θ - sin²θ)(cos²θ + sin²θ)/[(1 - tan²θ)(1 + tan²θ)] =
= (cos²θ - sin²θ) × 1/[(1 - tan²θ)sec²θ] (since (cos²θ + sin²θ) = 1 and 1 + tan²θ = sec²θ)
Also, Using the identity a² - b² = (a + b)(a - b), we have
(cos²θ - sin²θ) × 1/[(1 - tan²θ)sec²θ] = (cosθ - sinθ)(cosθ + sinθ)/[(1 - tanθ)(1 + tanθ)sec²θ]
= (cosθ - sinθ)(cosθ + sinθ)/[(cosθ - sinθ)/cosθ × (cosθ + sinθ)/cosθ × sec²θ]
= (cosθ - sinθ)(cosθ + sinθ)/[(cosθ - sinθ)(cosθ + sinθ)/cos²θ × 1/cos²θ]
= (cosθ - sinθ)(cosθ + sinθ)cos⁴θ/[(cosθ - sinθ)(cosθ + sinθ)]
= 1 × cos⁴θ
= cos⁴θ
So, the trigonometric identity (cos⁴θ - sin⁴θ)/(1 - tan⁴θ) = cos⁴θ

Matthew picks flowers and sells them to tourists. the function s(t) approximates how many flowers matthew picks per hour. the function w(h) represents how hours per week matthew spends picking flowers. what are the units of measurement for the composite function s(w(h))?
Flowers/week is the unit of measurement for the composite function s(W(h)).
Given that the function w(h) indicates the number of hours per week that Matthew spends picking flowers and the function s(t) approximates how many flowers he collects every hour.
The process of combining two or more functions into one function is known as the composition of functions. The output of the function enclosed in parenthesis becomes the input of the function outside of them in a composition of functions.
Hours of flowers is the unit of function s(t).
Additionally, consider that W(h) denotes the number of hours per week that Matthew spends gathering flowers.
W(h) = hours/week as a unit.
The unit of the composite function s(W(h)) will be = (Flowershours)(hoursweek) = Flowersweek.
Hence, the units of measurement for the composite function s(W(h))where the function s(t) approximates how many flowers Matthew picks per hour and the function w(h) represents how hours per week Matthew spends picking flowers is flowers/week.

The time to hit the ground is 1.9 seconds
How to determine the time?The height equation is given as:
d = -16t^2 + h0
A stone thrown from 60 feet has an initial height of 60.
This means that:
h0 = 60
So, we have:
d = -16t^2 + 60
When the stone hits the ground, d = 0
So, we have:
-16t^2 + 60 = 0
Evaluate the like terms
-16t^2 = -60
Divide by -16
t^2 = 3.75
Evaluate the square root
t = 1.9
Hence, the time to hit the ground is 1.9 seconds
