Answer: Here is the answer.
Step-by-step explanation:
Remark
What value of k will make the entire polynomial = 0 when k is meant to be a factor? In brief, solve the polynomial when f(-3) is substituted into the right hand side.
f(x) = 2x3+x2+kx+18
f(-3) = 2x3+x2+kx+18
f(-3) = 2(-3)^3 + (-3)^2 - 3k + 18 = 0
-54 + 9 - 3k + 18 = 0
-54 + 9 + 18 - 3k = 0
-27 - 3k = 0
- 3k = 27
k = 27/ - 3 = - 9
Answer
k = -9
Check
2x^3 + x^2 - 9x + 18 = 0
2(-3)^3 + (-3^2) - 9(-3) + 18 = 0
-54 + 9 + 27 + 18 = 0 Just as it should be.
He makes 1,172.50. you find this by dividing 2345 by 2 (since that’s his BI weekly salary which means every 2 weeks he gets paid) when you divide by 2 you get 1,172.50
Answer:
Step-by-step explanation:
Triangle ABC is an equilateral triangle, then:
=> angle ABC = angle BAC = angle ACB = 60 deg
AB // CE, according to alternative interior pair of angles theorem:
=> angle ACE = angle BAC = angle ABC = 60 deg (1)
B, C, and D are colinear, then:
angle ECD + angle ACE + angle ACB = 180 deg
=> angle ECD = 180 - angle ACE - angle ACB = 180 - 60 - 60 = 60 deg (2)
From (1) and (2):
=>angle ACE = angle ECD = 60 deg
Answer:
Opposite of -88 feet
Step-by-step explanation:
the opposite of -88 is positive 88, which means its coming off of the ground. negative would go into the ground.
