Answer:
a = -8 + sqrt(10)/ 10
Step-by-step explanation:
-4log(a+8)=2
Divide each side by -4
-4/-4log(a+8)=2/-4
log (a+8) = -1/2
Raise each side to the power of 10
10 ^ log(a+8)= 10^-1/2
a+8 = 1/ sqrt(10)
Subtract 8 from each side
a +8-8 = -8 + 1 /sqrt(10)
a = -8 + 1/sqrt(10)
We do not like sqrt's in the denominator
a = -8 + sqrt(10)/ 10
Without the graph to look at, there is no way to answer that question. Good luck to you.
Answer: Grand Canyon
Step-by-step explanation: Grand Canyon is a proper noun that should be capitalized. The other options are just nouns that don't need to be capitalized.
All triangles have 180o in them when the 3 angles making them up are added together.
Givens
F = 90
E = 29
D = ???
Equation
<D + <E + <F = 180
Substitute and solve
<D + 90 + 29 = 180
<D + 119 = 180
<D = 180 - 119
<D = 61
