Answer:
I think it's a because when if the graph was actually able to pass the y axis before the x axis it would be ( 10, 0) however since it's the x axis coming first and it is negative it is going to be ( 0 , -10 )
Answer:
7.5
Step-by-step explanation:
= 0.5477225575
Multiply it by 5
= 2.738612788
Square it
7.5 ![ft^{2}](https://tex.z-dn.net/?f=ft%5E%7B2%7D)
Hope this helped. :)
Answer:
z = 28
Step-by-step explanation:
Let's try this first:
6 = something - 1
Something = 7
Next:
We know that "something" is 1/4z
1/4z = 7
Divide both sides by 1/4 to isolate z
z = 28
Hope this helps :)
Have an awesome day!!

<h3><u>Given </u><u>:</u><u>-</u></h3>
- <u>We </u><u>have </u><u>given </u><u>in </u><u>the </u><u>question </u><u>that</u><u>, </u><u> </u><u>Robin </u><u>is </u><u>flying </u><u>a </u><u>kite</u><u>. </u>
- <u>She </u><u>ties </u><u>the </u><u>5</u><u>0</u><u> </u><u>foot </u><u>kite </u><u>string </u><u>to </u><u>the </u><u>ground </u><u>.</u>
- <u>The</u><u> </u><u>kite </u><u>is </u><u>flying </u><u>at </u><u>4</u><u>0</u><u> </u><u>feet </u><u>high </u>
<h3><u>To </u><u>Find </u><u>:</u><u>-</u></h3>
- <u>We </u><u>have </u><u>to </u><u>find </u><u>the </u><u>measure </u><u>of </u><u>the </u><u>angle </u><u>the </u><u>string </u><u>forms </u><u>with </u><u>the </u><u>group </u><u>that </u><u>is </u><u>angle </u><u>of </u><u>elevation</u><u>. </u>
<h3><u>Let's </u><u>Begin </u><u>:</u><u>-</u></h3>
<u>According </u><u>to </u><u>the </u><u>given</u><u> </u><u>question</u><u>, </u>
- Hypotenuse AC ( Distance of string from the ground) = 50 ft.
- Perpendicular height AB ( Distance of the kite from the ground) = 40 ft.
<h3><u>Therefore</u><u>, </u></h3>
<u>By </u><u>using </u><u>trigonometric </u><u>ratios</u><u>,</u><u> </u>
{ ![\bold{\pink{ Sin Φ = }}{\bold{\pink{\dfrac{Perpendicular}{Hypotenuse }}}}](https://tex.z-dn.net/?f=%5Cbold%7B%5Cpink%7B%20Sin%20%CE%A6%20%3D%20%7D%7D%7B%5Cbold%7B%5Cpink%7B%5Cdfrac%7BPerpendicular%7D%7BHypotenuse%20%7D%7D%7D%7D)

}
<u>The </u><u>Angle </u><u>of </u><u>elevation </u><u>will </u><u>be </u>
<u>[</u><u> </u><u>The </u><u>angle </u><u>that </u><u>is </u><u>formed </u><u>between </u><u>the </u><u>line </u><u>of </u><u>sight </u><u>and </u><u>base </u><u>of </u><u>the </u><u>triangle </u><u>is </u><u>called </u><u>angle </u><u>of </u><u>elevation </u><u>]</u>
![\bold{\pink{Sin Φ = }}{\bold{\pink{\dfrac{AB}{AC }}}}](https://tex.z-dn.net/?f=%5Cbold%7B%5Cpink%7BSin%20%CE%A6%20%3D%20%7D%7D%7B%5Cbold%7B%5Cpink%7B%5Cdfrac%7BAB%7D%7BAC%20%7D%7D%7D%7D)

![\sf{ Sin Φ = }{\sf{\dfrac{4}{5}}}](https://tex.z-dn.net/?f=%5Csf%7B%20Sin%20%CE%A6%20%3D%20%7D%7B%5Csf%7B%5Cdfrac%7B4%7D%7B5%7D%7D%7D)
![\sf{ Sin Φ = 0.8 }](https://tex.z-dn.net/?f=%5Csf%7B%20Sin%20%CE%A6%20%3D%200.8%20%7D)
![\bold{\green{ Φ = 45.83° }}](https://tex.z-dn.net/?f=%5Cbold%7B%5Cgreen%7B%20%20%CE%A6%20%3D%2045.83%C2%B0%20%7D%7D)
Hence, The measure of the angle the string forms with the ground is 45.83° .
