Answer:
y²+5y+4=y²+4y+y+4=y(y+4)+1(y+4)=
<u>(y+4)(y+1)</u>
Answer:
1/5 + 2/5 i sqrt(6) = .2 + .98i
1/5 - 2/5 i sqrt(6) = .2 - .98i
Step-by-step explanation:
5z^2−9z=−7z−5
We need to get all the terms on one side (set the right side equal to zero)
Add 7z to each side
5z^2−9z+7z=−7z+7z−5
5z^2−2z=−5
Add 5 to each side
5z^2−2z+5=−5 +5
5z^2−2z+5=0
This is in the form
az^2 +bz+c = 0 so we can use the quadratic formula
where a = 5 b = -2 and c = 5
-b± sqrt(b^2-4ac)

2a
-(-2)± sqrt((-2)^2-4(5)5)
-------------------------
2(5)
2± sqrt(4-100)

1/5 ± 2/5 i sqrt(6)
Splitting the ±
1/5 + 2/5 i sqrt(6) = .2 + .98i
1/5 - 2/5 i sqrt(6) = .2 - .98i
Answer:
D.
Step-by-step explanation:
You got the answer right it D
(0.03) multiplied by (0.004) is 0.00012
Multiply 3 by 4 and add all the zeros together
So 0.00012
Answer:
$1930
Step-by-step explanation:
770 + 24.64 (48-1)
there are 4 quarters in a year so you do 48 terms instead of 12.
Answer:
= 2
Step-by-step explanation:
# g(x) = x^2 + 3 hence g(-2) = (−2)2+3=4+3=7
and so f(g(-2)) = f(7) = 7 - 5 = 2
