A baseball player throws a baseball from a height of 1 m above the ground and its height is given by the equation h= -3.2^2+ 12.

Bingel [31]

Answer:

4.1 sec

Step-by-step explanation:

h(t)=-3.2t^2+12.8t+1

h(t)=-3.2(t^2-4t)+1

h(t)=-3.2(t^2-4t+4-4)+1

h(t)=13.8-3.2(t-2)^2

For the ball to touch ground, h(t)=0.

13.8-3.2(t-2)^2=0

(t-2)=2.0766

t=4.07≈4.1 sec.

I need to know the answer I’m working on rational numubers

lesya [120]

Answer:

Fraction Form: $\frac{11}{24}$

Decimal Form: 0.4583

Step-by-step explanation:

Apply the fraction rule: $\frac{-a}{b} = - \frac{a}{b}$

$\frac{-5}{12} = - \frac{5}{12}$

$- \frac{5}{12} + \frac{7}{8}$

Least Common Multiple (LCM) of 12 and 8: 24

$- \frac{5}{12} x \frac{2}{2} = - \frac{10}{24} \\\\\frac{7}{8} x \frac{3}{3} = \frac{21}{24} \\\\- \frac{10}{24} + \frac{21}{24}$

Apply the fraction rule:

$\frac{a}{c} + \frac{b}{c}= \frac{a + b}{c}\\\\\frac{-10 + 21}{24} \\\\-10 + 21 = 11\\\\\frac{11}{24}$
