Option D. 17/10 or 1.7 is correct or 1 7/10 is also correct :)
Answer:
k = 3
Step-by-step explanation:
If p-1 is a factor of p⁴+p²+p-k, then we can express the polynomial in form
p⁴+p²+p-k = (p-1) * (ap³ + bp² + cp + d)
where a,b,c,d are constants. The important thing is that we can subst in p = 1 to make the polynomial zero. We can do this for original polynomial. WE must have to equal to 0 when we use p = 1 substitution...
1⁴+1²+1-k = 0
3 - k = 0
k = 3
C
because the units respond to the numbers
A = 225<span>°</span> in rectangular form
is written as x = cos (225) = -0.707
y = sin (225) = -0.707
The answer is y = x
This angle is in the third quadrant, x and y have the same amplitude and both are negative.
Variable: not consistent or having a fixed pattern liable to change. Or able to be changed or adapted.
Sorry that is all I know and I need a picture
