What is (x+3i)(x-3i)(x+1)(x-1) multiplied out?
morpeh [17]
We can start with the first two sets

(x+3i)(x-3i) = x²-9i² then simplify it to x²+9

multiply the next two

(x+1)(x-1) = x²-1

then multiply those two together

(x²+9)(x²-1) = x∧4-x²+9x²-9

combine like terms x∧4+8²-9

that is your answer

Points P and Q belong to segment AB . If AB = a, AP = 2PQ = 2QB, find the distance: midpoints between AP QB
Digiron [165]

Answer: The distace between midpoints of AP and QB is \frac{a}{8}.

Step-by-step explanation: Points P and Q are between points A and B and the segment AB measures a, then:

AP + PQ + QB = a

According to the question, AP = 2 PQ = 2QB, so:

PQ = \frac{AP}{2}

QB = \frac{AP}{2}

Substituing:

AP + 2*(\frac{AP}{2}) = a

2AP = a

AP = \frac{a}{2}

Since the distance is between midpoints of AP and QB:

2QB = AP

QB = \frac{AP}{2}

QB = \frac{a}{2}*\frac{1}{2}

QB = \frac{a}{4}

MIdpoint is the point that divides the segment in half, so:

<u>Midpoint of AP</u>:

\frac{AP}{2} = \frac{a}{2}*\frac{1}{2}

\frac{AP}{2} = \frac{a}{4}

<u>Midpoint of QB</u>:

\frac{QB}{2} = \frac{a}{4}*\frac{1}{2}

\frac{QB}{2} = \frac{a}{8}

The distance is:

d = \frac{a}{4} - \frac{a}{8}

d = \frac{a}{8}

Brainliest and 50 points! Data picture is added below
Semmy [17]

Answer/Step-by-step explanation:

A. The cluster is where the 100 is to the 235. The outlier is 1,110 cause it is way out in the open alone almost 300 numbers away from its nearest number

B. For the correlation if you notice how it goes from 200... > 400...> 600...>800...it kinda like a pattern of  adding 200

C. The independent variable  is temperature and the dependent is sales. since the amount of money made depends on the temperature.
