23. Find the perimeter and area of the rectangle below. 10x^2 7xy^2

Answers

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.

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:

f(- 2) = 8

Step-by-step explanation:

To evaluate f(- 2) , substitute x = - 2 into f(x) , that is

f(- 2) = 3(- 2)² + (- 2) - 2 = 3(4) - 2 - 2 = 12 - 4 = 8

A model rocket is launched directly upward at a speed of 20 meters per second from the ground. The function f(t)=−4.9t2+20t, models the relationship between the height of the rocket and the time after launch, t, in seconds. When, in seconds after launch, will the rocket reach its highest point? Round to two decimal places.

Answers

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]

Question
A bag contains 3 pink gumballs, 4 red gumballs, and 2 green gumballs. Find the probability that you do not draw all green
gumballs if there are 3 drawings that occur and the gumballs are replaced after each draw. Round your answer to two
decimal places.
Provide your answer below

Answers

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.
