The function h(t) = 2.3 + 50t - 1.86t^2 models the height of an arrow shot from a bow on Mars, where h(t) is the height in metres and t is time in seconds. How long does the arrow stay in flight?

The arrow stay in flight for 26.92 seconds

Step-by-step explanation:

We are given that  the height of an arrow shot from a bow on Mars is modeled by equation:

Where h(t) is the height of arrow

t is the time in seconds

Now we are supposed to find How long does the arrow stay in flight?

Substitute h(t)=0

So,

t=-.04 , 26.92

Since the time cannot be negative

So,the arrow stay in flight for 26.92 seconds

correct answers below:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
