If he maintained a steady speed, he would drive 3 kilometers far after 3 hours.
<h3>What is steady speed?</h3>
Uniform or steady speed refers to a body's motion in a given direction without acceleration.
Since steady speed means a constant speed in changing time intervals, we would consider he speed as 1 km/h.
Time for which he is maintaining the steady speed is 3 h.
We know by the formula, Distance = Speed × Time
Therefore, putting the values given we get
Distance = 1 × 3 kilometers
Hence, distance travelled by he after 3 hours of maintaining steady speed is 3 kilometers.

Answer:
I = ∫₀¹ eˣ dx
I = ∫₀¹ e⁻ˣ dx
Step-by-step explanation:
Trapezoidal rule will be an overestimate if the function is concave up.
We can determine this by looking at the graph, or by evaluating the second derivative. If the second derivative is positive on the interval, the function is concave up.
f(x) = eˣ
f'(x) = eˣ
f"(x) = eˣ
On the interval [0, 1], f(x) is concave up.
f(x) = e⁻ˣ
f'(x) = -e⁻ˣ
f"(x) = e⁻ˣ
On the interval [0, 1], f(x) is concave up.
f(x) = √x = x^½
f'(x) = ½ x^(-½)
f"(x) = -¼ x^(-³/₂)
On the interval [0, 1], f(x) is concave down.
f(x) = sin x
f'(x) = cos x
f"(x) = -sin x
On the interval [0, 1], f(x) is concave down.
Answer: 97/20 or 4 17/20
Step-by-step explanation:
5/1 - 3/20 = 97/20, to an improper fraction gives 4 17/20
Answer:
m+n=140
Step-by-step explanation:
So the angles in a triangle always add up to 180. We already know that the first angle in the triangle is 40 degrees because it's shown in the angle below the triangle. So we have 140 degrees left since 40 is taken up. That eans m+n=140
