An acorn falls from the branch of a tree to the ground 25 feet below. The distance, S, that the acorn is from the ground as it f

Hunter-Best [27]

Answer:

$0$

Step-by-step explanation:

We are given that,

The fall of the acorn is represented by the function,

$S(t) =-16t^2+25$

Equating S(t) to 0 gives,

$0=-16t^2+25$

i.e. $16^2=25$

i.e. $t^{2}=\frac{25}{16}$

i.e. $t=\pm \frac{5}{4}$

Since, time cannot be negative.

So, $t=\frac{5}{4}$ i.e. 1.25 seconds is the time when the acorn will reach the ground.

Thus, from the figure below, we see that,

The interval in which the acorn is in the moving air is $0$ .

Answer:

AE = 60 units

Step-by-step explanation:

GE is one third the length of AE so...

GE = 1/3(AE)

20 = 1/3x

3(20) = (1/3x)3/1

60 = x

x = 60

AE = 60 units

Solve each inequality. Then compare the solutions.<br><br> 3x +4> 16<br> - 2x + 19< 11

Makovka662 [10]

Answer:

$3x + 4 > 16 \\ 3x > 16 - 4 \\ \frac{3x}{3} > \frac{12}{3} \\ x > 4 \\ \\ - 2x + 19 < 11 \\ - 2x < 11 - 19 \\ - 2x < - 8 \\ \frac{ - 2x}{ - 2} > \frac{ - 8}{ - 2} \\ x > 4 \\ \\ comparing \\ 4 < x > 4$
