Answer:
<h3>The common ratio is 2</h3>
Step-by-step explanation:
To find the common ratio of the geometric sequence divide the previous term by the next term
That's
0.9 / 0.45 = 2
1.8 / 0.9 = 2
Therefore the common ratio is 2

Answer: a) √50
b) n = 1 + 7i
Step-by-step explanation:
first, the modulus of a complex number z = a + bi is
IzI = √(a^2 + b^2)
The fact that n is complex does not mean that n doesn't has a real part, so we must write our numbers as:
m = 2 + 6i
n = a + bi
Im + nI = 3√10
Im + n I = √(a^2 + b^2 + 2^2 + 6^2)= 3√10
= √(a^2 + b^2 + 40) = 3√10
a^2 + b^2 + 40 = 3^2*10 = 9*10 = 90
a^2 + b^2 = 90 - 40 = 50
√(a^2 + b^2 ) = InI = √50
The modulus of n must be equal to the square root of 50.
now we can find any values a and b such a^2 + b^2 = 50.
for example, a = 1 and b = 7
1^2 + 7^2 = 1 + 49 = 50
Then a possible value for n is:
n = 1 + 7i
Answer:
Joshua's account had a greater change.
Step-by-step explanation:
Both accounts had $100
Joshua's account now has $67.25 which means he used $32.75
Crystal's account now has $131.97 which means he saved $31.97.
Joshua had a greater change of balance.
