Temperature at 9:00PM was 15° By 5 AM the temperature had dropped 20° what was the temperature at 5 PM
Arisa [49]
From 9 P.M. to 5 A.M. the temperature dropped 20°, making the rate over 8 hours, -2.5° Per Hour. By 5 A.M., the temperature is -5° since we had to do 15 - 20. From 5 AM to 5 P.M. is 12 hours so -2.5 x 12 = -30 making 30 how much the temperature dropped between 5 A.M. to 5 P.M. Finally, our last equation is -5 - 30 making -35 our answer.

Evaluate f(t)=-2t2+ 1 for f(-3).
podryga [215]

Answer:

7

Step-by-step explanation:

First, plug-in f(-3) into t in the function:

f(-3)=-2(-3) +1

Second, multiply -2 and -3 to get 6:

f(-3)=-2(-3)+1⇒f(-3)=6+1

Third, add 6 and 1 to get your answer:

f(-3)= 6+1⇒f(-3)=7
