Height at an instance of time is given by :
h(t) = -4( t - 2 )² + 5 .....1
Differentiating above equation with respect to t .
[tex]\dfrac{dh}{dt}= -4\times ( -2 ) ( t - 2 ) \\\\\dfrac{dh}{dt}= 8(t-2)[/tex]
Now, for maximum , [tex]\dfrac{dh}{dt} = 0[/tex] .
8( t - 2 ) = 0
t = 2
Putting value of t = 2 in given equation, we get :
h( 2 ) = -4( 2 - 2 )² + 5
h( 2 ) = 5 m
Therefore, maximum height rocket can reach is 5 m.
What is the answer.........
Answer:
1 is correct
2 is correct
3 is incorrect
4 is incorrect
5 is correct
Step-by-step explanation:
1 is correct because the statue lies the same distance from both entrances.
2 is correct because B is also the same distance from both entrances.
3 is the opposite of 2, saying that B is not equal distance from both entrances, making it false.
4 is incorrect because a is closer to the upper entrance.
5 is correct because it is basically the same question as 2, saying b is the same distance from both entrances.

A shopkeeper buys 10 television sets from a retailer at a rate of Euro 15,000 per set. He sells half of them at a profit of 25 % and rest half at a loss of 20%. Find the overall profit/loss faced by the shopkeeper.
Answer: Profit of $3,750
Step-by-step explanation:
Sold half of the sets at a profit of 25%;
= (15,000 * 5 sets) * 25%
= $18,750
Sold the other half at a loss of 20%;
= (15,000 * 5) * 20%
= $15,000
Profit (loss) = 18,750 - 15,000
= $3,750
Please help me with this
Answer:
The length= 16cm
The width= 6cm
The two long sides are 8cm both so 8 + 8 = 16
And the two short sides are 3cm both so 3 + 3 = 6
So your length should be 16cm and your width 6cm

The elevations of four points above sea level there are -47 ft, -20 ft,-8 ft, and -18 ft. The elevation of the point closest to sea lvl (level) is _____ ft, and the elevation of the point farthest from sea lvl is _____ ft. (FILL IN THE BLANKS PLS HELP)
Answer:
The elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.
Step-by-step explanation:
Let's assume the elevation above the sea level is on a number line, then we have to arrange the given number from lowest to highest. These are the numbers in ascending order.
–42ft, –20ft, –18ft, –8ft.
From here we see that, the elevation closest to the sea level is –42ft and the elevation farthest from the sea level is –8ft.
Which linear inequality is represented by the graph?
Answer:
The answer would be the last option. y<2/3x-1
Step-by-step explanation:
The slope is 2/3 and the line crosses the y axis at -1. Since the shaded part is below the line it would make the sign less than (<)
