Answer:

<em>5.33 secs</em>

Step-by-step explanation:

Given the equation of the height modeled by the equation/

h(t) = -3.2 + 12.5t + 24.8

The object strikes the ground when the height h(t) is zero

Substituting h(t) = 0 into the expression

h(t) = -3.2t² + 12.5t + 24.8

0 =  -3.2t² + 12.5t + 24.8

-3.2t² + 12.5t + 24.8 = 0

Multiply through by minus sign

3.2t² - 12.5t - 24.8 = 0

From the expression a = 3.2, b = -12.5 and c = -24.8

t = -(-12.5)±√(-12.5)²-4(3.2)(-24.8)/2(3.2)

t = 12.5±√156.25+317.44)/6.4

t = 12.5±√473.69/6.42

t = 12.5±21.76/6.42

t = 12.5+21.76/6.42

t = 34.26/6.42

t = 5.33secs

<em>Hence the object strike the ground after 5.33 secs</em>

mylen [45]

Answer:

3.8m

Step-by-step explanation:

Since Lara is putting lace trim around the border of a circular tablecloth, by the time she finishes she has covered the circumference.

The circumference of a circle is calculated using:

C=\pi \: d

where d is the diameter of the circle.

It was given that the diameter of the circular table cloth is 1.2 meters.

C=3.14 \times 1.2

C=3.768

Therefore the length of the lace she needed is 3.8m
