Answer:

{(1, 2), (3, 2), (5, 7)}

Step-by-step explanation:

A function has a one to one correspondence

Each x can go to only 1 y value

{(1, 2), (3, 2), (5, 7)} function

{(3, 5), (-1, 7), (3, 9)} 3 goes to more than 1 y value

{(1, 2), (1, 4), (1, 6)} 1 goes to more than 1 y value

Answer:

\huge \boxed{ \{(1, 2), (3, 2), (5, 7)\} }

Step-by-step explanation:

\sf A \ function \ is \ a \ relation \ if \ each \ x \ value \ is \ for \ each \ y \ value.

\{(1, 2), (3, 2), (5, 7)\} \ \sf represents \ a \ function.

\{(3, 5), (-1, 7), (3, 9)\} \ \sf does \ not \ represent \ a \ function.

\{(1, 2), (1, 4), (1, 6)\} \ \sf does \ not \ represent \ a \ function.

What is matrix X if 0.5X=A? Matrix A=[6 -12 4 6].
vladimir1956 [14]

Answer:

See attachment

Step-by-step explanation:

The given matrix equation is:

0.5X = A.

To find Matrix X, we need to multiply both sides of the equation by 2 to obtain:

2 \times 0.5X =2 \times  A

This simplifies to;

X = 2A

By scalar multiplication, we multiply each entry in the matrix A by to 2 to obtain matrix X.

Speed boat departed 1.75 hrs after steam boat1.8 hrs after speed boat departure, steam boat has sailed for a total: 1.8+1.75 = 3.55 hrssteam boat's speed is 36.8 km/hr, so it has traveled: 3.55*36.8 = 130.64 km
speed boat is 86.9 km behind steam boat. so it is 130.64-86.9 = 43.74 km from portspeed boat's speed = 43.74/1.8 = 24.3 km/hr
