Hello,
Radius= √((4-0)²+(5-0)²)=√41
Equation of the circle : x²+y²=41
You would set it up: .5/100 = x/490 and then cross multiply .5 time 490 and 100 times x, and end up with: 245=100x. divide by 100, and get 2.45
Answer:8498
Step-by-step explanation:
(7*1000)+(7*200)+(7*10)+(7*4)
7000+1400+70+28

Answer:
y = 0.87x + 0.02
Step-by-step explanation:
Euros as a function of dollars means that euros is y and dollars are x.
We are given 2 points: (4, 3.5) and (10, 8.72)
slope = (8.72 - 3.5)/(10 - 4)
slope = 5.22/6 = 0.87
y = 0.87x + b
3.5 = 0.87(4) + b
b = 0.02
y = 0.87x + 0.02
Speed=distance/time
distance=176km
time=2hr
speed=176km/2hr=88km/1hr
88kmph
