About 104 ft

To find out how tall the tree is, you can draw a diagram to help you picture it.

Picture the tree and you as a triangle. You are 55 ft from the tree. That means that the base of your triangle is 55 ft. The opposite side is the straight side you are trying to find. Let's say that value is x. Then, you have the angle of elevation from your eyes to the top of the tree, which is 61˚.

Tangent ratio = opposite side/adjacent side. These are the sides we have, so we are going to use them by using a tangent ratio.

So, now we have arrived at our equation: tan 61 = x/55

We can simplify this easily by multiplying 55 on both sides. x ÷ 55 = tan 61. x ÷ 55 • 55 = 55 • tan 61. So, x = 55 • tan 61 ≈ 99.2 ft

But, we still have to account for the height of your eyes. To do this, we just add 4.5 ft to 99.2 ft = 103.7 ≈ 104, so the tree is about 104 ft tall

The following tables each show the inventory of a warehouse and the number of orders for four different products which have been
snow_lady [41]
Orders: x
Inventory: y

1) First table
x2-x1=6-3→x2-x1=3
y2-y1=1920-1960→y2-y1=-40

x3-x2=9-6→x3-x2=3=x2-x1
y3-y2=1900-1920→y3-y2=-20 different to y2-y1=-40. The table does not represent a linear relationship.

2) Second table
x2-x1=7-5→x2-x1=2
y2-y1=1860-1900→y2-y1=-40

x3-x2=9-7→x3-x2=2=x2-x1
y3-y2=1820-1860→y3-y2=-40=y2-y1

x4-x3=11-9→x4-x3=2=x3-x2
y4-y3=1780-1820→y4-y3=-40=y3-y2

x5-x4=13-11→x5-x4=2=x4-x3
y5-y4=1740-1780→y5-y4=-40=y4-y3

The table represents a linear relationship.

3) Third table
x2-x1=2-1→x2-x1=1
y2-y1=1000-2000→y2-y1=-1000

x3-x2=3-2→x3-x2=1=x2-x1
y3-y2=500-1000→y3-y2=-500 different to y2-y1=-1000. The table does not represent a linear relationship.

4) Fourth table
x2-x1=6-4→x2-x1=2
y2-y1=1640-1840→y2-y1=-200

x3-x2=8-6→x3-x2=2=x2-x1
y3-y2=1360-1640→y3-y2=-280 different to y2-y1=-200. The table does not represent a linear relationship.

Answer: The second <span>table best represents a linear relationship.</span>

Someone please help <br> WILL GIVE BRAINLIEST
Flauer [41]

Answer:

y=3x+1

Step-by-step explanation:

I'm very bad at explaining things so im sorry if this doesn't make any sense

the y axis goes up

the x axis goes sideways

to fill in the "y = ____x+_____"

you find a point on the line, see how far up it is from 0,0 and put that in the first blank space, in this case its 3. then you find how much it goes over on the x axis. in this case its 1 over. so you would put 1.
