Euler's formula for Vertices, Edges and faces is V-E+F = 2
Replace the letters with the given information and solve for the missing one.
From the problem V ( Vertices) = 11 and F (faces) = 15.
11 - E + 15 = 2
11 + 15 = 26
26 - E = 2
E = 26-2
E = 24
The answer is b. 24
elg=124°
eld=2x
elg+eld=180°=>eld=180°-124°=56°/eld=2x=56°=>x=56°/2=28°
eld+dlh=180°=>dlh=180°-56°=124°
hlg+dlh=180°=>hlg=180°-124°=56°
Answer: 0.99
Step-by-step explanation: sin 90 Divided by 85 = sin x divided by 13
sin x =13x sin 90 divided by 85
sin x = 13divided by 85
sin x = .152941176
arc sine of .152941176= 8.79741071 degrees
cos 8.79741071 = .988235294
.99
Answer:
first angle of tht side is 90
n then the whole cirlcle is 360 so~
Step-by-step explanation:
If it looks like this
y = 161*(0.725)^t then it's a decay. Reason: the base is under 1. Try a couple of values for t say 0,1,2
y = 161 * (0.725)^0
y = 161
y = 161 * (0.725)^1
y = 161 * 0.725
y = 116.7
y = 161 * (0.725)^2
y = 161 * (0.5256
y = 84.63
You can see that the function is steadily getting smaller. Remember if the base is under 1 and more than 0 the function decays. If it is greater than 1 then the function grows.
Just to make sure we understand what I'm saying
0 < base < 1
y = a ( base)^power.
