Answer:
3.5°/hour
Step-by-step explanation:
Rate of change of temperature=change in temperature/Change in time
Change in temperature
=82° - 54°
=28°
Change in time=3:00pm - 7:00am
=8:00 hours
Rate of change of temperature=28°/8 hours
=3.5°/hour
(n^4 - 1) = (n^2 - 1) (n^2 +1) = (n - 1) (n + 1) (n^2 + 1)
His score is 50
How to:
First test grade:0
Second test grade:50
Third test grade: 100
Add all three and divide by 3
Answer:
The answer to your question is: third option, it's a parabola
Step-by-step explanation:
f(x) = (x + 4)²
f(x) = x² + 4
f(x) = (x - 4)² I think this is the right answer, because when get the vertex, the signs are changed, if the -4 is negative, it means that the graph must be located in +4.
f(x) = x² - 4
Answer/Step-by-step explanation:
An expression is a series of number without any signs so expression would be the first one.
Inequality would be when they do a sign like > or <, etc. so it would be the 2nd one.
Equation would be when they have an equal sign which would be the 3rd one.
Simple Ex.
Expression : 2 + 66 / 11 - 3 x 2
Inequality : g + h > f
Expression : 4j - 3 = j
Hope this helps :)
