Answer:
a)
Step-by-step explanation:
x/5 = $8.96/7 a)
Step-by-step explanation:
Close. You correctly set up the integrals. When integrating e²ˣ:
∫ e²ˣ dx
½ ∫ 2 e²ˣ dx
½ e²ˣ + C
So the coefficient should be ½, not 2.
[eˣ − ½ e²ˣ]₋₁⁰ + [½ e²ˣ − eˣ]₀¹
[(e⁰ − ½ e⁰) − (e⁻¹ − ½ e⁻²)] + [(½ e² − e) − (½ e⁰ − e⁰)]
1 − ½ − e⁻¹ + ½ e⁻² + ½ e² − e − ½ + 1
-e⁻¹ + ½ e⁻² + ½ e² − e + 1
Answer:
Step-by-step explanation:
There are two conditions that need to be in place.
- The sum of the angles must equal 180
- There must be exactly 3 angles.
A has too many angles. The answer is not A.
B same as A
C same as A
D doesn't add to 180. Not D
You have no answer unless there is another choice.
