Here you would want to use the sine function, since it’s making a triangle with the ground, and length of the string, the height to the kite. This can be found by 65sin(70°) which is ≈ 61.08 meters
Answer:
y=2x-8
Step-by-step explanation:
<em>Slope-Intercept Form </em>
<em>y=mx+b where y and x are variables, m is the slope, and b is the y-intercept</em>
<u>1. Find slope using the slope formula </u>![\frac{y_{2}-y_{1} }{x_{2}-x_{1}}](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
![\frac{2-4}{5-6} =\frac{-2}{-1} =2](https://tex.z-dn.net/?f=%5Cfrac%7B2-4%7D%7B5-6%7D%20%3D%5Cfrac%7B-2%7D%7B-1%7D%20%3D2)
You now have
y=2x+b
<u>2. Plug in one of the given points into the equation and solve for b</u>
y=2x+b
2=2(5)+b
2=10+b
-8=b
<u>Final Answer:</u>
y=2x-8
4x means "x" times the number 4. You can rewrite 4x as:
x + x + x + x
x^4 (x to the 4th power) means "x" times itself, 4 times. You can rewrite x^4 as:
x × x × x × x
