Answer:
The answer is 5 5/8.
The correct answer is not in the options
Answer:
c
Step-by-step explanation:
From the graph as x gets larger and becomes positive f(x) approaches 0 so the answer is C.
Since C is 2mi east of A and 2mi south of B, the shortest distance from A to B would be a straight line which is equal to the hypotenuse of a right triangle with a base of 2mi and a height of 2mi..
d^2=x^2+y^2
d^2=2^2+2^2
d^2=4+4
d^2=2*4
d=√(2*4)
d=2√2 mi (exact)
d≈2.83 mi (to nearest hundredth of a mile)
|-1/5| < |-1/3| < |-7|
Your answer:
B. y = -1/5 x^2; y = -1/3 x^2; y = -7x^2
Look at the picture.
Ed : (0,205)(4,197)
slope(m) = (197 - 205) / (4 - 0) = -8/4 = -2
y = mx + b
slope(m) = -2
(0,205)...x = 0 and y = 205
time to sub
205 = -2(0) + b
205 = b
equation is : y = -2x + 205...so Ed loses 2 lbs per week
Eric :
y = -1.5x + 200...so Eric loses 1.5 lbs per week
when they started, Ed weighed 205 lbs and Eric weighed 200 lbs
* of the two, Eric loses fewer lbs per week. When the two began their respective weight-loss programs, Ed was heavier by 5 lbs.
