Answer:
Y is 150° and x is 30°
Step-by-step explanation:
i think its because the bottom angle near to 150° is a vertically opposite angle so yeah
Im not so sure myself
Answer:
![y=-40x+300](https://tex.z-dn.net/?f=y%3D-40x%2B300)
Step-by-step explanation:
Let x be the time (in hours) and y be the distance from Denver (in miles).
When car begins, it is 300 miles from Denver, so x = 0 hours and y = 300 miles.
After 3 hours, it is 180 miles from Denver, then x = 3 hours and y = 180 miles.
Write the equation of the line passing through the points (0,300) and (3,180). The slope of this line is
![\dfrac{180-300}{3-0}=\dfrac{-120}{3}=-40](https://tex.z-dn.net/?f=%5Cdfrac%7B180-300%7D%7B3-0%7D%3D%5Cdfrac%7B-120%7D%7B3%7D%3D-40)
y-intercept is at (0,300), hence the equation of the line is
![y=-40x+300](https://tex.z-dn.net/?f=y%3D-40x%2B300)
15*19=285
base times height is the formula
Answer:
12920
Step-by-step explanation :
distance covered = d = ∫![\int\limits^a_b ({sqrt{f'(t)^{2} +g'(t)^2\\}}) \, dt](https://tex.z-dn.net/?f=%5Cint%5Climits%5Ea_b%20%28%7Bsqrt%7Bf%27%28t%29%5E%7B2%7D%20%2Bg%27%28t%29%5E2%5C%5C%7D%7D%29%20%5C%2C%20dt)
a = t = 20
b = t = 0
f'(t) = 646 : f'(t)² = 417316
g'(t) = 5 : g'(t)² = 25
d = ![\int\limits^a_b {646} \, dt](https://tex.z-dn.net/?f=%5Cint%5Climits%5Ea_b%20%7B646%7D%20%5C%2C%20dt)
t = 20 & t = 0
d = 646t
d = 646*20 = 12920
