Answer:
Josh is wrong.
Step-by-step explanation:
5^-x / 5^x = 5^(-x-x) = 5^-2x
= 1 / 5^2x
(you subtract the exponents when dividing )
So Josh is wrong ( he would be correct if we were multiplying)
Answer:
Yes, provided they are all the same size.
Step-by-step explanation:
4/5=0.8
1/2=0.5
3/4=0.75
0.8+0.5+0.75=n
8+5=13
0.8+0.5=1.3
1.3+0.75=2.05
Answer:
1) log7 (5*8)= log7(40)
2) log2(11) -log2(9)=log2(11/9)
3)2log9 2=log9(2^2)
Answer: C
Step-by-step explanation:
x = 2
- 6
x + 6 = 2
((x+6)/2 = )^2
(x+6/2)^2 = y+2
y = (x+6/2)^2 -2
y= 1/4x^2 +3x +7
Answer:
∠LPN = 57°
Step-by-step explanation:
arc LMN = 360° - 102° - 144° = 114°
∠LPN = 114°/2 = 57°
