Answer:
16.78 seconds
Step-by-step explanation:
speed = Distance Traveled / time
thus speed =29.79 Km/sec
time =distance Traveled/speed (from above formula)
time taken=500 km ÷ 29.79 Km/sec
∴time taken=16.78 seconds

Option (2) and Option (3) is the correct answer .
<u>Requ</u><u>ired</u><u> </u><u>Ex</u><u>plaination</u><u> </u><u>:</u>
Scenario 2 : The height of a stone shot by a catapult reaches a maximum height and then falls on the ground.
- The graph of this scenario is a downward parabola. Therefore option 2 is correct.
Scenario 3 : The sale of product increases at first and then decreases.
- The graph of this scenario is a downward parabola. Therefore option 3 is correct.

Answer:
- small prism: 630 m²
- large prism: 2520 m²
Step-by-step explanation:
The total surface area of the prism is the sum of the base area and the lateral area. The base area is made up of two right triangles, so will be the product of the triangle leg dimensions. The lateral area is made up of three rectangles whose width is that of the prism and whose equivalent length is the perimeter of the triangle base.
For the smaller prism, the area is ...
(20 m)(21 m) +(3 m)(20 m + 21 m + 29 m) = 420 m² +210 m² = 630 m²
The larger prism is similar, with a scale factor of 2, so its area will be 2² = 4 times that of the smaller prism:
4×630 m² = 2520 m²
__
In summary, the total surface area of each prism is ...
- small prism: 630 m²
- large prism: 2520 m²
