Answer:

Step-by-step explanation:

Given that a rocket path is given by

h(x) = -4x^2 + 16x

When it hits the ground h(x) =0

Hence we get

-4x^2 + 16x=0\\x=0, 4

i.e. after 4 minutes the rocket hits the ground

2) Given that

s(t) = -16t^2 + 48t + 280.

We have to find time t when height >280

s(t) = -16t^2 + 48t + 280>280\\\\t=0, 3

Between 0 and 3 seconds the object would be above the building.

1.) You plug a number into the variable x. Then you will solve the equation for h(x) to find the time it takes for the rocket to travel the path given.

Solve for Inequality
uysha [10]

Answer:

x > -1

Step-by-step explanation:

Divide the whole inequality by 9.

(\frac{x}{3}+1)>\frac{6}{9}

Subtract 1.

\frac{x}{3} > \frac{2}{3} - 1

\frac{x}{3} > -\frac{1}{3}

Multiply by 3.

x > -1

Answer:

 y = -1/3x + 3 2/3

Step-by-step explanation:

step 1. find the slope of the given line

y2-y1/x2-x1          2 - 4/ 3 + 3 = - 1 / 3

take the opposite of that and there is your slope

step 2. plug in the values to the following equation using the given point:

y - y1 = m ( x - x1 )          y - 4 = - 1/3 ( x + 1 )

step 3. solve for y

y-4 = -1/3(x+1)

-1/3(x) and -1/3(1)  ----> y-4 = -1/3x-1/3

y-4+4 = -1/3x-1/3+4  ---->  y = -1/3x + 3 2/3

<em>hope this helps. if you need more help lmk in the comments. i am in algebra two so you can trust me. Happy holidays</em>

On 12/31/18, Hite Industries reported retained earnings of $475,000 on its balance sheet, and it reported that it had $135,000 o
olganol [36]

Answer:

Dividends = $105000

So option (c) will be correct answer

Step-by-step explanation:

We have given that Retained earning on 12/31/18 is $475000

And retained earning on 12/31/18 is $445000

Net income = $135000

Change in retained income = $475000-$445000 = $30000

We have to find dividends

We know that dividends is given by

Dividends = net income - change in retained income = $135000-$30000 = $105000

So option (c) will be correct answer

Help me plz<br> thank u!
viktelen [127]

Answer:

x = 41

y = 65

z = 107

Step-by-step explanation:

y and 65 are vertically opposite angles. Vertically opposite angles are equal.

y = 65

74 + y + x = 180

74 + 65 + x = 180

139 + x = 180

x = 180 - 139

x = 41

z is the exterior angle, whereas 66 and x are interior angles in a triangle.

Formula : -

Exterior angle = Sum of two interior angles

z = 66 + x

  = 66 + 41

z = 107
