Angle ADE = 59 degrees
(4x+15)+(13x+7)=90degrees
17x+22=90degrees
68=17x
4=x
Angle DBC= 59 degrees
Angle DCB = 90degrees
Triangle = 180degrees
90+59=149
180-149=31 degrees
Angle EDC = 31
90-31=59 degrees
Angle ADE = 59 degrees

Answer:

ADE=59º

Step-by-step explanation:

4x+15+13x+7=90

17x+22=90

17x=68

x=4

angle B=angle ADE so we plug in x=4 into 13x+7

13(4)+7=59º

Answer:

$24(f(n))$

Step-by-step explanation:

$f(n+3) = 3^{n+3}\\f(n+1) = 3^{n+1}$

$f(n+3) - f(n+1) = 3^{n+3} - 3^{n+1}$

$= 27(3^n) - 3(3^n)$

$= 24(3^n)$

$= 24(f(n))$

How much times does it take for the first black/clear part to fall through the photo gate timer, starting from the rest? Plastic

Alik [6]

I can figure out this is a frefall motion.

Starting from rest => Vo = 0

Then, use the equation: d = [1/2]gt^2 => t = √(2d/g)

d = width of a black/clear stripe pair = 5cm = 0.05m

g ≈ 10 m/s^2 (the real value is about 9.81 m/s^2)

t =√(2*0.05m/10m/s^2) = 0.1 s

Answer: approximately 0.1 s
