Why is radian measure used in Geometry?

1 answer:

Vladimir [108]3 years ago

3 0

The infinite series description of trig functions is much neater when the argument is radians. For example, for small angles, sin(x) ≈ x when x is in radians. You could say that radians is the "natural" measurement unit for angles, just as "e" is the "natural" base of logarithms.

If the angle measure were degrees or grads or arcseconds, obnoxious scale factors would show up everywhere.

Given: 2x^2+3x-5, g(x)=x+9. Find: (fg)(3)

Svetradugi [14.3K]

Answer:

264

Step-by-step explanation:

$f(x)=2x^2+3x-5$

$g(x)=x+9$

$(fg)(x)=f(x) \times g(x)$

$\implies (fg)(x)=(2x^2+3x-5)(x+9)$

$(fg)(3)=(2(3)^2+3(3)-5)(3+9)$

$\implies (fg)(3)=22 \times 12$

$\implies (fg)(3)=264$

if a town with a population of 500 doubles in size ever 9 years, what will the population be 36 years from now?

s344n2d4d5 [400]

The population of the town in 36 years would be 8000.

<h3>What would be the population of the town in 36 years?</h3>

The formula that can be used to determine the town's population is:
FV = P (1 + r)^n

Where:

FV = Future value
P = Present value
R = rate of growth = 100%
N = number of years = 36/9 = 4

500 x 2^4 = 8000
