Answer
Explanation:
Step1: Determine the applicable function
Since ( t = -10 ) and the first piece of the piece - wise function is defined for ( t\leq - 10 ), we use the function ( f(t)=t^{2}-5t ) when ( t = - 10 ).
Step2: Substitute ( t=-10 ) into the function
Substitute ( t=-10 ) into ( f(t)=t^{2}-5t ). We get ( f(-10)=(-10)^{2}-5\times(-10) ).
First, calculate ( (-10)^{2}=100 ) and ( 5\times(-10)=- 50 ), so ( - 5\times(-10) = 50 ).
Then, ( f(-10)=100 + 50=150 ).
Answer:
( 150 )
