Answer:

Step-by-step explanation:

-t²+4t+5=0

t²-4t-5=0

t²-5t+t-5=0

t(t-5)+1(t-5)=0

(t-5)(t+1)=0

t=5,-1

when t=0,d=5

actual time it it is in air=5-1=4 seconds.

Answer:

Step-by-step explanation:

A. 2 meters to centimeters

1 m = 100 cm

$2 m = 2 \times 100 \\2 m = 200 cm = 2 \times 10^2$

B)108 centimeters to meters

100 cm =1 m

$1 cm = \frac{1}{100} m \\108 cm = \frac{108}{100}=108 \times 10^{-2} m$

C)2.49 meters to centimeters

1 m = 100 cm

$2.49 m = 2.49 \times 100 = \frac{249}{100} \times 100 = 249 cm$

D)50 centimeters to meters

100 cm = 1m

$1 cm = \frac{1}{100} m \\50 cm = \frac{50}{100}= 5 \times 10^{-1} m$

E)6.3 meters to centimeters

1 m = 100 cm

$6.3 m = 6.3 \times 100=\frac{63}{10} \times 100 = 630 cm$

F)7 centimeters to meters

100 cm = 1 m

$1 cm = \frac{1}{100} m\\\\7 cm = \frac{7}{100} = 7 \times 10^{-2} m$

a)4 meters to millimeters

1 m = 1000 mm

$4 m = 4000 = 4 \times 10^3 mm$

b)1.7 meters to millimeters

1 m = 1000 mm

$1.7 m = 1.7 \times 1000= \frac{17}{10} \times 1000=17 \times 10^2 mm$
