3√10^4x is equivalent to -√10 3/4^x and -4√10^3x they are all equivalent
Answer:
The first one is -2x^2 - 21x + 4, the second one is -15 (I think, not 100% sure), the third one is 4xyz + 3yz + 5x - 4 (also not 100% on this one)
Travel distance by light in a second = 3*10^5 kms
Travel distance by light in 60 seconds =
3*10^5 * 60
180 * 10^5
1.8 * 10^7 kms
Answer:
A
Step-by-step explanation:
Discriminant= 8^2-4(16)(1)
=0
FUTURE VALUE = PRESENT VALUE * (1 + r)^t
PV = 220,000
r = 3%
t = 7 years
FV = 220,000 * (1 + 3%)^7
FV = 220,000 * (1.03)^7
FV = 220,000 * 1.22987386542487
FV = 270,572.25
