Lerok [7]

Answer:

$14,030.48

Step-by-step explanation:

We can use the following formula to solve:

A=P(1-r)^t

<em>P = principal value </em>

<em>r = rate (decimal) </em>

<em>t = time (years)</em>

<em />

First, lets change 7.3% into a decimal:

7.3% -> \frac{7.3}{100} -> 0.073

Next, plug in the values:

A=19,000(1-0.073)^4

A=14,030.48

The value will be $14,030.48

<h3>Answer:  B) 4</h3>

This is because the z coordinate is -4. So we move down 4 units on the z axis. The z axis is basically a vertical pole planted in the ground, and the xy plane is the flat floor.

It's a bit tricky to visualize so try to imagine that you're in this 3D space personally.

Or you could imagine that something like z = -4 means you are in basement level 4 of a building (say a parking garage) and something like z = 6 means you're on the 6th floor above the ground.

WILL GIVE BRAINLIEST IF CORRECT
Ivahew [28]

Answer:

The second answer.

Step-by-step explanation:

Tim is correct. Absolute value is just the distance away from 0. In this case, both P and Q are 3/8 away from zero, even though they have opposite signs. In fact, opposites signs of the same number will always have the same absolute value because they are the same distance from 0.

So, it is the second one.

Hope this helps!

Find the width of rectangle if it's area is (3x^2 + 9xy + 6y^2 ) square centimeters .
Juli2301 [7.4K]
Given:
Length = 3x + 6y cm
Area = 3x² + 9xy + 6y²

Because Area = Width * Length, therefore
Width = Area/Length
           = (3x² + 9xy + 6y²)/(3x + 6y).

Width = Width= \frac{3( x^{2} +3xy+2 y^{2}) }{3(x+2y)}
Width=\frac{(x+y)(x+2y)}{x+2y} =x+y

Answer:  x+y
