Answer:
Answer is 2
Step-by-step explanation:
We know that average rate of change of a function f(x) in the interval (a,b) is
Using this we can say that
Using properties of integration we have
3 to 6 integral = 20-5 =15
0 to2 integral = -3=5 =-8
Thus integral form 0 to 6 would be = -8+15+5 = 12
Average rate of change form 0 to 6 =
Answer is 2
Answer:
Height of tree is <em>15 m.</em>
<em></em>
Step-by-step explanation:
Given that student is 20 m away from the foot of tree.
and table is 1.5 m above the ground.
The angle of elevation is: 34°28'
Please refer to the attached image. The given situation can be mapped to a right angled triangle as shown in the image.
AB = CP = 20 m
CA = PB = 1.5 m
= 34°28' = 34.46°
To find TB = ?
we can use trigonometric function tangent to find TP in right angled
Now, adding PB to TP will give us the height of tree, TB
Now, height of tree TB = TP + PB
TB = 13.72 + 1.5 = 15.22 <em>15 m</em>
If two events are independent, then
.
Use formulas for conditional probabilities:
.
For independent events these formulas will be:
.
Now in your case and
.
This shows that the only correct choice is A.
