I thought I saw this one earlier and there were people answering. Guess not.
h(t) = 5 + 98t - 4.9t²
h(0) = 5 meters
h(5) = 5 + 98(5) - 4.9(5)² = 372.5 meters
h(10) = 5 + 98(10) - 4.9(10)² = 5 + 980 - 490 = 495 meters
h(15) = 5 + 98(15) - 4.9(15²) = 372.5 meters
h(20) = 5 meters
I'll leave the graphing to you, plot those points
(0,5), (5,372,5),(10,495),(15,372.5) (20,5)
and connect the dots
It's coming down pretty fast at 5 feet up 20 seconds. That last bit is 5/495 or 1% of the trip, so probably double the average speed of around 50m/s so 100msec or .05 sec to go 5 meters.
So it's in the ground at about 20.05 seconds after launch.
Answer: 20.05 meters
Answer:
Correct option is
C
(2,0)
5x−3y=10
=>5x−3×0=10
=>5x=10
=>x=2
Graph of the equation 5x−3y=10 cuts the x-axis at the point (2,0)

The answer is going to be 6 1/12 ft. hope that helped
The area of the portion of the rectangular field that has crops growing is 4.7 x 10² ft².
<h3>
Area of the rectangle</h3>
The area of the rectangle is calculated as follows;
Area of rectangle = L x b
where;
- L is length of the rectangle
- b is the breadth of the rectangle
Given parameters;
- Length of the rectangle = 3.5 x 10 ft = 35 ft
- Breadth of the rectangle = 2.7 x 10 ft = 27 ft
Area = 35 ft x 27 ft
Area = 945 ft²
<h3>Area of the portion of the field that has crops growing</h3>
Area = ¹/₂ x 945 ft²
Area = 472.5 ft²
Area = 4.7 x 10² ft² (2 significant digits)
The two significant digits was chosen based on the number of significant digits of the rectangle dimensions (that is, the length and breadth are given in 2 significant digits, so the area has to be in 2 significant digits to maintain consistency).

I put 0.75 because it is 25% discount which means you need to subtract it from 100.the rest is there.hope this helps if it does please mark brainliest
