Answer:

Step-by-step explanation:

Draw a picture.

θ = 81.7°

tanθ = height/121.6

height = 121.6tanθ ≅ 833.5

The building is 833.5 ft high.

:::::

When shadow is 2×121.6 = 243.2 ft long, tanθ = height/243.2

θ = arctan(height/243.2) ≅ 73.7°

Twenty one is no less than the sum of a number and -2

Gala2k [10]

$x+(-2)=21
$
get rid of -2 by subtracting it from 21
$x+(-2)=21-(-2)$
Now you get your answer
$x=23$
Hope this helps! :)

Find the taylor polynomial t3(x) for the function f centered at the number

Vlad [161]

$e^{-3x}=\displaystyle\sum_{n=0}^\infty\frac{(-3x)^n}{n!}=1-3x+9x^2+\cdots$
$\sin2x=\displaystyle\sum_{n=0}^\infty\frac{(-1)^n(2x)^{2n+1}}{(2n+1)!}=2x-\dfrac{4x^3}3+\cdots$

$e^{-3x}\sin2x=\left(1-3x+9x^2+\cdots\right)\left(2x-\dfrac{4x^3}3+\cdots\right)$
$\approx T_3(x)=(1-3x+9x^2)\left(2x-\dfrac{4x^3}3\right)$
$T_3(x)=2x-6x^2+\left(18-\dfrac43\right)x^3$
$T_3(x)=2x-6x^2+\dfrac{50}3x^3$

Find the length here

Vera_Pavlovna [14]

Answer:

The correct answer is

D) 66.35

The sine of the angle = the length of the opposite side. the length of the hypotenuse.

The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.

The tangent of the angle = the length of the opposite side. the length of the adjacent side.

So in shorthand notation:

sin = o/h cos = a/h tan = o/a
