The inequality sign is greater than or equal to, which means the line would be solid and the shaded portion would be to the right of the line.
The correct graph would be A.
Answer:
96
lower right
Step-by-step explanation:
Part 1
Givens
a1 = - 20
d = +4
n = 30
Equation
a30 = a1 + (n - 1)d
Solution
a30 = -20 + (30 - 1)*4
a30 = -20 + 29*4
a30 = - 20 + 116
a30 = 96
=====================
Part 2
Formula
Sum = (a1 + L)*n/2
n = 30
So only the two on the right can be considered
a1 = -20
L = 96
Sum = (-20 + 96)30/2 is the bottom right. D if you think of it that way.
<u>Answer:</u>
If x-2 is a factor of p(x) = x^{4} - 3 x^{2} + 2 x - 8 ,then p(x) = 0
<u>Solution:</u>
According to factor theorem of polynomials,
x-a is a factor of polynomial p(x), if and only p(a)=0
<u>Step 1:</u>
Since x-2 is factor of p(x),
x - 2 = 0
x = 2
<u>Step 2:</u>
By substituting x = 2 in equation 1,
p(x) = 16 - 3(4 ) + 4 -8
p(x) = 16 - 12 - 4
p(x) = 16 - 16
p(x) = 0
Since x - 2 is a factor of p(x) , we get p(x)=0
