Given:

The height of ball is represented by the equation is

[tex]h=-16t^2+6t+4[/tex]

To find:

The time taken by ball to hit the ground.

Solution:

First we need to find the zeroes of the given equation. So, for zeroes h=0.

[tex]-16t^2+6t+4=0[/tex]

Here, [tex]a=-16,b=6,c=4[/tex]. Usingquadratic formula, we get

[tex]t=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]t=\dfrac{-6\pm \sqrt{6^2-4(-16)(4)}}{2(-16)}[/tex]

[tex]t=\dfrac{-6\pm \sqrt{36+256}}{-32}[/tex]

[tex]t=\dfrac{-6\pm \sqrt{292}}{-32}[/tex]

[tex]t=-\dfrac{-6+ 17.088}{-32},\dfrac{-6+ 17.088}{-32}[/tex]

[tex]t=0.7215,-0.3465[/tex]

Time cannon be negative. So, at t=0.7215 the ball will hit the ground. Time taken by ball to hit the ground is

[tex]t=0.7215-0[/tex]

[tex]t=0.7215[/tex]

Round your answer to the nearest hundredth.

[tex]t\approx 0.72[/tex]

So, the ball will hit the ground after 0.72 seconds.

Therefore, the correct option is A.

0.72

Answer:

x = 4f/nz

Step-by-step explanation:

nxz - f = 3f  solve for x

    nxz =  3f+f

Factor of nxz is x(nz)

  x(nz) = 3f+f

  x(nz) = 4f

MUltiply both side with 1/nz and you get

 x =  4f/nz

Answer:

m = 0, y = -6

Step-by-step explanation:

using point slope form :

[tex]y - y_{1} = m(x - x_{1})[/tex]

y-y1=m(x-x1) ; initial point (x1,y1) = (4,-6), final point (x,y) = (7,-6).

one substituted, it should look like this:

-6--6 = m(7-4),

-6+6= m(7-4)

0 = m(7-4)

0 = 3m

0/3 = 3/3m

0 = m

m = 0/3 = 0

Answer:

a)   Number of laundry he can do with this box  = 78 laundries.

b)   Price he paying for each load =  0.256 $

Explanation:

Total scoop contained in detergent box = 195 scoops.

Scoops used by each load of laundry =  scoops = 2.5 scoops

Number of laundry he can do with this box = 195/2.5 = 78 laundries.

Price of detergent box = 19.99 $

Price he paying for each load = Total price/ Number of loads

                                                  = 19.99/78

                                                  = 0.256 $

Answer:

95

Step-by-step explanation:

Let 2x be how many red/green marbles there are,

let 5x be how many blue marbles there are, and

let 7x be how many white marbles there are.

2x + 2x + 5x + 7x = 304

16x = 304

x = 19

As 5x is defined as how many blue marbles there are, we could just plug x for 19:

5*19 = 95

I hope this helped, and if it did please consider giving me brainliest :)

Answer:

95

Step-by-step explanation:

Let r, g, b, w be the number of red, green, blue, and white marbles, respectively. Since r : g : b : w = 2 : 2 : 5 : 7, there is some value of x for which r = 2 x, g = 2x, b = 5x, and w = 7x. Then, we have

                                      304 = r + g + b + w

                                      = (2x) + (2x) + (5x) + (7x)  

                                                              = 16x

Dividing both sides of 16x = 304 by 16 gives x=19. This gives us r = 38, g = 38, b = 95, w = 133, so I have 95 blue marbles.

Answer:

Hope This Helps :)

Answer:  y= 9x+ 25

Step-by-step explanation:

to calculate the slope, rise/run   rise is difference in y-values 25 -(-2) =27

run is difference in x-values  0-(-3) = 3 .  27/3 = 9

b= y-intercept   Given: 25

We want to graph a line with a slope of -5 that contains the point (-3, -4), the graph can be seen at the end.

We first need to get the equation of the line that we must graph.

The general line equation is:

y = a*x + b

Where a is the slope and b is the y-intercept.

Here we know that the slope must be -5, so we have:

y = -5*x + b

And we know that it must contain the point (-3, -4), then we can replace these values for x and y in the equation and solve it for b:

-4 = -5*-3 + b

-4 = 15 + b

-4 - 15 = b

-19 = b

Then the linear equation is:

y = -5*x - 19

To graph this you just need to find two points on the line and then connect them with a line, we already know one (-3, -4). To get another we can evaluate the equation in any value of x, for example with x = 0 we get:

y = -5*0 - 19

y = -19

Then the other point is (0, -19)

With these two points you will get the graph below:

[tex]\displaystyle 5x + y = -19\:or\:y = -5x - 19[/tex]

Step-by-step explanation:

Plug the information into the Slope-Intercept Formula:

[tex]\displaystyle y = mx + b \\ \\ -4 = -5[-3] + b \hookrightarrow -4 = 15 + b; -19 = b \\ \\ y = -5x - 19[/tex]

Suppose you need to write this equation in standard form. You would follow these procedures:
