Answer:
x2 = -0.600000
x3 = -0.521600
Step-by-step explanation:
Given the formula;
xn+1 = (xn)³-5/10
x2 = (x1)³-5/10
Given x1 = -1
x2 = (-1)³-5/10
x2 = (-1-5)/10
x2 = -6/10
x2 = -0.600000
x3 = (x3)³-5/10
Given x3 = -0.6
x3 = (-0.6)³-5/10
x3 = (-0.216-5)/10
x3 = -5.216/10
x3 = -0.521600
Answer:
4.6
Step-by-step explanation:
5x +3 = 20
5x = 23
x = 4.6
Answer:
The answer is (x+y)^3
Step-by-step explanation:
using the division/subtraction law of indices
In indices division is equal to subtraction on powers
(x+y)^5 ÷ (x+y)^2
=(x+y)^5-2
=(x+y)^3
The ending time would be 3:01 p.m. You simply add 15 to 246 and configure it into the way a clock tells time!
Answer:
b)
Step-by-step explanation:
A is invertible if and only if det(A)≠0. Let's compute the determinant of A and find the values k for which it is nonzero.
Using Sarrus's rule, we obtain that

Note that the determinant is a quadratic equation on k, which can be factored as above.
Now the determinant is only zero if k=5 or k=2 (the zeroes of the quadratic polynomial). Therefore, if k≠2,5 the determinant is nonzero so A is invertible.
