Sam has 15 identical rectangular windows in his home. The length of each window is twice the width, and the area of each window

is 8 square feet. Sam wants to put weather stripping around the perimeters of all the windows. If the weather stripping costs $0.25 per foot, how much will he spend?

The answe would be 300 because, the perimeter of the windows is 12, then you have to multiply 25 to 12 then bam you get 300, yay!

Find the distance and displacement for the following figures :
Vinil7 [7]

The figure (i) have a distance of 15.996 meters and a displacement of 13.892 meters and (ii) a distance of 480 centimeters and a displacement of 339.411 centimeters

<h3>How to find the distance and displacement in each trajectory</h3>

The distance is the sum of the lengths that form a trajectory and the displacement is the distance between the <em>initial</em> and <em>final</em> point of a trajectory. Then, we have the following results for each case:

Case I

Distance

d = 5 m + 0.5π · (7 m)

d ≈ 15.996 m

Displacement

D = \sqrt{(12\,m)^{2}+(7 m)^{2}}

D ≈ 13.892 m

Case II

Distance

d = 8 · (60 cm)

d = 480 cm

Displacement

D =\sqrt{(240\,cm)^{2}+(240\,cm)^{2}}

D ≈ 339.411 cm

Can someone help me expand this in log: log_3 x^2 yz and the picture above
BigorU [14]

Answer:

log_4(\frac{xy}{3})=log_4(x) + log_4 (y) - log_4 (3)

Step-by-step explanation:

using the properties of logarithms, the log of a product gives the addition of logs, and the log of a quotient gives the subtraction of logs;

log_4(\frac{xy}{3})=log_4(x) + log_4 (y) - log_4 (3)

What is the slope of the line in this graph?
Nina [5.8K]

The slope of the line 5/7.

How do i know this?

Well the slope of a line is considered as rise/run.

So we start at the beginning and then go up until the line intersects a corner again. Then we mark that down.

Go back to the beginning and count how many times it takes to reach the height of the intersected corner. So it is 5.

Then we go to the right until we reach the point. And it takes 7 squares to reach it, so the slope it 5/7.

Your welcome! :D
