Step-by-step explanation:

Answer:

The rocket will reach its highest point about 2.04 seconds.

Step-by-step explanation:

The function:

[tex]f(t)=-4.9t^2+20t[/tex]

Models the relationship between the height of the rocket and the time after launch t in seconds.

Since this is a quadratic function, the rocket will reach its highest point at its vertex. The vertex of a quadratic is given by:

[tex]\displaystyle \Big(-\frac{b}{2a}, f\Big(-\frac{b}{2a}\Big)\Big)[/tex]

In this case, a = -4.9, b = 20, and c = 0. Thus:

[tex]\displaystyle t=\frac{-(20)}{2(-4.9)}=\frac{10}{4.9}\approx 2.04[/tex]

The rocket reaches its maximum height after 10/4.9 or about 2.04 seconds.

Further Notes:

Then the maximum height of the rocket will be f(10/4.9):

[tex]\displaystyle f\Big(\frac{10}{4.9}\Big)=-4.9\Big(\frac{10}{4.9}\Big)^2+20\Big(\frac{10}{4.9}\Big)\approx20.41\text{ feet}[/tex]

Answer:

.47

Step-by-step explanation:

9 gumballs in all

7 of them are not green

'ng' = not green

P(ng,ng,ng) = 7/9 x 7/9 x 7/9 = .47

The probability will be 0.87.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that,

Number of Pink gumballs = 3,

Number of Red gumballs = 4,

Number of Green gumballs = 2,

Now,

Total number of gumballs = 3 + 4 + 2 = 9,

Thus, total number of ways of selecting 3 gumball

= 9 x 9 x 9

= 729

Number of Green gumballs = 2

Number of gumballs other than green = 9 - 2 = 7

So, Number of ways to draw 3 gumballs other than green is;

= 7 x 7 x 7

= 243

And, Number of ways to draw one green and two other gumballs in 3 draw = 2 x 7 x 7 + 7 x 2 x 7 + 7 x 7 x 2

       = 294

( Since the green gumballs can be drawn in 1st, 2nd, and 3rd draw.)

Thus, The probability of not drawing all 2 green gumballs is;

= 343 + 294 /729

= 637/729

= 0.87

So, The probability will be 0.87.

Answer:

Option A

Step-by-step explanation:

Number of components assembled by the new employee per day,

N(t) = [tex]\frac{50t}{t+4}[/tex]

Number of components assembled by the experienced employee per day,

E(t) = [tex]\frac{70t}{t+3}[/tex]

Difference in number of components assembled per day by experienced ane new employee

D(t)= E(t) - N(t)

D(t) = [tex]\frac{70t}{t+3}-\frac{50t}{t+4}[/tex]

      = [tex]\frac{70t(t+4)-50t(t+3)}{(t+3)(t+4)}[/tex]

      = [tex]\frac{70t^2+280t-50t^2-150t}{(t+3)(t+4)}[/tex]

      = [tex]\frac{20t^2+130t}{(t+3)(t+4)}[/tex]

      = [tex]\frac{10t(2t+13)}{(t+4)(t+3)}[/tex]

Therefore, Option A will be the answer.

Answer:

Area= 70x^3y^2

Perimeter = 20x^2 + 14 xy^2

Step-by-step explanation:

Area is just multiplying the length and width, I multiplied the constants first which gets us 70 then multiplied the variables, they combine however only the x's can be multiplied to each other which results in 70x^3y^2 .  The perimeter you just multiply the length by two and the width by two, they are separate because the variables when added to each other do not combine.
