A 6.5 ft. Tall car, parked next to a truck, casts a 33.2 ft. Shadow. If the truck casts a shadow that is 51.5 ft. Long then how tall is the truck? Round to the nearest tenth.

The truck is 10.0 ft tall.

Step-by-step explanation:

In a particular time ,

Shadow of an item is proportional to its height.

Equation of direct proportion:

Similarly,

Hence, the truck is 10.0 ft tall.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
