A ferry takes several trips between points A and B. It moves at a constant speed of 0.35 miles/minute and takes the same route o
Fofino [41]

The answer is  -|0.35 t -14| +14

<u>Step-by-step explanation</u>:

The problem statement is asking for an expression for distance in miles, so the constants in the expression will be miles. In the time it takes to get to point B (40 minutes), the ferry has gone (0.35 mi/min)×(40 min) = 14 mi. Hence the maximum value of the function must be 14. The only function with that characteristic is the one of selection D.

Answer:

The answer is "99.82% and 86.99%".

Step-by-step explanation:

In point a:

=P(X < 45)\\\\= P(Z < \frac{45-29.09}{5.46}) \\\\=P(Z < 2.9139)\\\\=0.9982\\\\=99.82\%

In point b:

=P(X >17)\\\\= P(Z > \frac{17-22.37}{4.77}) \\\\=P(Z > -1.1258)\\\\=0.8699\\\\=86.99\% \\\\

Answer:

(x,f(x)) = (-1,8) -- Another point

a = 8

Step-by-step explanation:

Given

f(x) = a|x|

(x,f(x)) = (1,8)

Solving (a): Another point

Substitute 1 for x and 8 for f(x) in f(x) = a|x|

8 = a|1|

Remove absolute bracket

8 = a*1

8 = a

a = 8

Substitute 8 for a in f(x) = a|x|

f(x) = 8|x|

Let x = -1

f(x) = 8|-1|

Remove absolute bracket

f(x) = 8*1

f(x) = 8

So, another point is:

(x,f(x)) = (-1,8)

Solving (b): The value of a

This has been solved in (a) above

a = 8
