Quadrilaterals Q and P are similar. What is the scale factor of the dilation that takes Q to P
aalyn [17]

Answer:

0.8

Step-by-step explanation:

The scale factor that takes Q to P

Here, we want to go from Q to P

To get this, we simply divide what we have in P by what we had in Q

Hence, what we do here is;

2/2.5 or 4/5 = 0.8

There are no results for The impedance Z in an AC (alternating current) circuit is a measure of how much the circuit impedes (hi
Semmy [17]

Answer:

Step-by-step explanation:

If the impedance is related to the voltage and the current by the formula V = IZ where;

V is the voltage

I is the current

Z is the impedance

Given

I = 0.4+3i

V = 0.3-2i

Voltage V = (0.4+3i)(0.3-2i)

V = 0.4(0.3)-0.8i+0.9i-6i²

V = 0.12+0.1i -6i²

Since i² = -1

V = 0.12+0.1i-6(-1)

V = 0.12+0.1i+6

V = 6.12+0.1i.

Hence the impedance is 6.12+0.1i

MariettaO [177]

Hello from MrBillDoesMath!

Answer:

The side length is at most 7 inches.

Discussion:

A regular hexagon is a 6-sided polygon where the length of each  side is the same. Let this length be L. Then the problem states that 6L < 42, so L < 7
