Answer: around 0.0064
i rounded it to the nearest hundred thousandth because the number will keep going on forever.
Answer:
(0.118, 4.882)
Step-by-step explanation:
If a motorist drives for m hours at 120km/hr, then the Distance of the motorist is expressed as;
Distance = Speed * time
da = 120m
If he drives n hours at 18km/hr;
db = 18 * n
db = 18n
Speed of the motorist altogether is expressed as;
Speed =78km/5hrs
Speed = 15.6km/hr
SInce the total distnce is 78km
120m + 18n = 78 ....1 ..... * 1
If total time is 5hrs
m + n = 5....2 ...*18
Solve simultaneously
120m + 18n = 78
18m + 18n = 90
Subtract
120m - 18m = 78-90
102m = -12
m = 0.118 hrs
m =
Since m + n = 5
n = 5 - m
= 5 - 12/102
n = 4.882
Hence (m,n) is (0.118, 4.882)
They have the same measurements but they are turned different ways
Coefficient of x i.e a is negative so parabola will open downwards
Graph attached
First you find what fits the qualifications of the function.
Part 1: f(0) fits with x<= 1, so you simply plug in 0 for that function.
(0)^2 = 1
Part 2: f(x) = 1
That means there is a horizontal straight line intersecting (0,1)
