All Real Numbers that are NOT Rational Numbers; cannot be expressed as
fractions, only non-repeating, non-terminating decimals
−√2 , −√5 3 , √21, √81 3 , √101
*Even roots (such as square roots) that don’t simplify to whole numbers are irrational.
Answer:
series is 15, 75, 375, 1875, 9375, 46875, 234375
Step-by-step explanation:
r=5
an = 234,375
n = 7
a1 = ?
a1 = an /rn-1
a1 = 234,375 /57-1
a1 = 15
a2 = 15*5 = 75
a3 = 15*25 = 375
a4 = 15*125 = 1875
a5 = 15*625 = 9375
a6 = 15*3125 = 46, 875
a7 = 15*15,625 = 234,375
Hence series is 15, 75, 375, 1875, 9375, 46875, 234375
Answer:
558.036 lb
Step-by-step explanation:
Let x is the amount of the sea water to collect 125 lb of sea salt
As given: 64 lb/ft³ has 0.0035 dissolved salt by weight
So the formula to find out the amount of the sea water is:
64 lb/ft³ * 0.0035 *x ft³ = 125 lb
<=> x = = 558.036 lb
Hope it will find you well.
Answer:
Using point-slope formula, if you're trying to find a parallel or perpendicular line to it.
Step-by-step explanation:
Step-by-step explanation:
well, it is supposed to be -3.
but you are right. something is wrong or missing here.
5x + 3 = 4x
x + 3 = 0
x = -3
maybe a "+ 1" is missing on the right side ?
5x + 3 = 4x + 1
gives us
x = -2
