choli [55]
Draw a right triangle to represent the problem.
The vertical height of the triangle is 9 ft, and it represents the tree.
The horizontal length, at the bottom of the tree is ground level and has a length of 13 ft.

Let x =  angle of elevation.

By definition,
tan x = 9/13 = 0.6923
x = arctan(0.6923) = 34.7 deg. = 35 deg (approx)

Is 70 thousand written in standard form or word form ? Explain
Stolb23 [73]
<span>70 thousand is written in short word form, because its written as a combination of numbers and letters. Standard form would be to write the number easily using multiplication with 10. That woul be: 70000=7*10^4. It;s 10^4 because the decimal point has been 4 laces to the left to get the number to be 7. Word form can be obtain by writing the number using letters. Long word form is: seventy thousand. But because sevety is written with number (70), this is short word form of the number,</span>

Write an equation that gives the proportional relationship of the graph.
viktelen [127]

The required equation is: y= 7x

Option C is correct.

Step-by-step explanation:

The proportional relationship can be found using the equation: y=k\,x

where x and y are the points and k is the constant of proportionality.

We need to find k.

From the graph given, we can locate points x and y:

x=5, y= 35 then k would be:

y=kx\\k=y/x\\k=35/5\\k=7

x=10, y=70 then k would be:

y=kx\\k=y/x\\k=70/10\\k=7

For each values of x and y, the constant of proportionality k is 7

So, the required equation is: y= 7x

Option C is correct.
