The sunflower is 2.387 meters tall.
The question is asking: which rounding will result in the greatest value?
To see, we need to round 2.387 to meter, tenth meter, and hundredth meter.
Meter - 2 meters
Tenth meter - 2.4 meters
Hundredth meter - 2.39 meters
As you see, rounding to the tenth meter gives the greatest value of 2.4. Therefore, Bahir should use a decimal rounded to the tenth meter.

Step-by-step explanation:
A) What is the speed of the pedestrian BC, CD, and DE?
Speed from B to C = distance/time = (40 - 20) / 4 = 20/4
= 5 km/h
Speed from C to D = distance/time = 0 / 2
= 0 km/h
Speed from D to E = distance/time = (20 - 0) / (10 - 6) = 20/4
= 5 km/h
B) After what time since the stop did he arrive at point E?
Since the stop at D, he arrived at E after (10 - 6) = 4 h
C) Write the formulas for function d(t) for sections BC, CD, and DE
For BC, d = 40 when t = 0 and d = 20 when t = 4
So d(t) = 40 - 5t
For CD, d = 20 when t = 4 and t = 6
So d(t) = 20
For DE, d = 20 when t = 6 and d = 0 when t = 10
So d(t) = 5 * (10 - t) or d(t) = 50 - 5t

10
Step-by-step explanation:
Answer: 4 / 5
Explanation:
1) For a right triangle, the ratio sine is defined as:
sin(x) = opposite-leg / hypotenuse
2) x is the angle. In this case: A
3) As per the figure, the opposite leg to tha angle A measures 28
4) As per the figure, the hypotenuse measures 35
5) Calculations:
sin(A) = 28 / 35
Simplify dividing both numerator and denominator by 7 => 28/35 = 4/5
In the given triangle, the verteces are A(-4, 1), B(-6, 5), C(-1, 2).
A refrection across the x-axis will result in A'(-4, -1), B'(-6, -5), C'(-1, -2)
A translation of 1 unit to the right will result in A"(-3, -1), B"(-5, -5), C"(0, -2)
A translation of 1 unit down will result in A"'(-3, -2), B"'(-5, -6), C"'(0, -3) which corresponds to points DEF.
Therefore, the series of transformation required to transform ABC to DEF are <span>a reflection across the x-axis followed by a translation of 1 unit right and 1 unit down.</span>
