-16t^2+16t+192= 0 (when the ball hits the ground, h will be zero)

Use the quadratic formula to solve the equation (If you don't know how to solve quadratic equations, just ping me dude and I'll try my best to help you)

We get x=-3 and 4

Now since time can't be negative, therefore the answer is after 4 seconds

Answer:

I believe the answer is- The mean and MAD can accurately describe the "typical" value in the symmetric data set.

Step-by-step explanation:

The other answers don't make sense because the mean and MAD are being used for symmetrical distributions and asymmetrical means uneven distributions.

NO LINKS!!! 14. Consider the table

iVinArrow [24]

Answer:

(a) rate of change = 8

(b) Function: y = 8x

Range: 0 ≤ y ≤ 16

Explanation:

Looks like a inverse variation sequence.

Inverse Variation formula: y = k(x)

Take two points: (1, 8), (2, 16)

Find the value of k which is constant also considered as rate of change.

Insert values:

8 = k(1)

k = 8

===========

16 = k(2)

k = 8

Equation: y = 8x

Domain lies in the x axis, Range lies in the y axis.

Here domain: 0 ≤ x ≤ 2

Here range: 0 ≤ y ≤ 16

You are choosing sprinklers for an irrigation system. One sprinkler that covers a full circle specifies a watering radius of 14

mihalych1998 [28]

Answer:

Area= 615 ft²

Step-by-step explanation:

Apply the formula for area of a circle to find the area watered when a sprinkler covers a full circle

Area of a circle= $\pi r^{2}$

r= 14ft

Area= 3.14 × 14²

Area=615.44 ft²

Area= 615 ft²

How many solutions do these equations have y= 3x+4 y+6=3x

Nataly [62]

Answer:

Step-by-step explanation:

hello :

the system is : y= 3x+4....(*)

y+6=3x....(**)

by (**) : y = 3x - 6

so : y= 3x+4

y= 3x - 6

means : 3x+4 = 3x - 6

4= -6.......(false)

conclusion : no reals solutions
