Answer:
x= 4
Step-by-step explanation:
2∧(x+1) = 32 = 2∧5
x+1 = 5
x= 4
Answer: 29.75%
Step-by-step explanation:
X/100 *80.33=23.90
80.33x=2390
X=2390/80.33 = 29.75
Answer:
No, it's false.
Step-by-step explanation:
Because 5.14>5.134.
Answer:
Step-by-step explanation:
Consider the quadratic expression
First, find its discriminant:
Note that 
then 
Use quadratic formula to find the roots:
Now, given quadratic expression is equivalent to
X^3 - 14x^2 + 49x = 0
Factor an x out:
x(x^2 - 14x + 49) = 0
Find two factors of 49 that add to -14 (-7 and -7). Convert the trinomial to two binomials:
x(x - 7)(x - 7) = 0
The zeros are:
x = 0 and x = 7.
7 occurs as a zero twice and therefore has a multiplicity of 2.
