Answer:
Angle <em>ADE</em> is an obtuse angle.
Step-by-step explanation:
An obtuse angle is an angle that "opens" greater than 90 degrees. The question asks which angle is an obtuse angle, so basically you follow the order of letters and see which one is greater than 90 degrees (btw, 90 degrees, also known as a right angle, looks like the corner of a square, and anything greater than that is an obtuse angle).
F(x) = 2(x-4)(x-5) does that seem right? ion know man, i got it off google. just trynna help doe
We are given that it takes 7 joules of heat to raise the
temperature of the bar by 1°C. Therefore this means that the heating capacity Cp
is:
Cp = 7 J / °C
The formula for the amount of heat required is:
heat = Cp (Tf – Ti)
where Ti is initial temperature = 25°C, and Tf is the
final temperature
When Tf = 26°C
heat = 7 (26 – 25) = 7 J
When Tf = 27°C
heat = 7 (27 – 25) = 14 J
When Tf = 28°C
heat = 7 (28 – 25) = 21 J
When Tf = 29°C
heat = 7 (29 – 25) = 28 J
When Tf = 30°C
heat = 7 (30 – 25) = 35 J
When Tf = 35°C
heat = 7 (35 – 25) = 70 J
