Answer:
−y−1=3
Step-by-step explanation:
Which equation can be used to find the solution of (1/4)^y+1=64?
This can be solved by power of indices
(1/4)^(y+1)=64
(4^-1)^(y + 1)= 4^3
Note
(x^a)^b = x^ab
Hence:
4^(-1)(y + 1)= 4^3
4^-y - 1 = 4^3
Divide both sides by 4
−y−1=3
Hence, the equation that can be used to find the solution of (1/4)^y+1=64 is
−y−1=3
I would go with C. because that is the closest average to the actual answer of 2 3/4 or 2.7575
3x2=6+1, 5x4=20+3, 7x6=42+5, 9x8=72+7, 10x9=90+?. Well it looks like the pattern is counting in odd numbers so I would say ?=9 so 10x9=90+9=99 :) hope this helps
Answer:
9.5
Step-by-step explanation:
Using the pythagorean theorem a^2+b^2=c^2, we can say that 3^2+b^2=10^2.
Simplify and you get 9+b^2=100. Subtract 9 from both sides and you get b^2=91. When you take the square root you get 9.53939... round to the nearest tenth and the missing side is 9.5.
