Answer:
the two roots are x = 1 and x = 4
Step-by-step explanation:
Data provided in the question:
(x³ − 64) (x⁵ − 1) = 0.
Now,
for the above relation to be true the following condition must be followed:
Either (x³ − 64) = 0 ............(1)
or
(x⁵ − 1) = 0 ..........(2)
Therefore,
considering the first equation, we have
(x³ − 64) = 0
adding 64 both sides, we get
x³ − 64 + 64 = 0 + 64
or
x³ = 64
taking the cube root both the sides, we have
∛x³ = ∛64
or
x = ∛(4 × 4 × 4)
or
x = 4
similarly considering the equation (2) , we have
(x⁵ − 1) = 0
adding the number 1 both the sides, we get
x⁵ − 1 + 1 = 0 + 1
or
x⁵ = 1
taking the fifth root both the sides, we get
also,
1 can be written as 1⁵
therefore,
or
x = 1
Hence,
the two roots are x = 1 and x = 4
Answer:
the probability is 69.15%
Step-by-step explanation:
We have that the mean is 38 inches (m) and the standard deviation is 2 inches (sd), so we are asked:
P (x <39)
P ((x - m) / sd <(39 -38) /2)
P (z <0.5)
If we look in the normal distribution table we have to:
P (x <39) = 0.6915
That is, the probability is 69.15%
Answer:
y = -⅓x - 9⅓
Step-by-step explanation:
-14 = -⅓[14] + b
-4⅔
-9⅓ = b
y = -⅓x - 9⅓
* Parallel lines have SIMILAR <em>RATE OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so -⅓ remains the way it is.
