Please help me with this! Picture is provided and only answer is you know it!
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.
Can a triangle have three acute angles? Justify your answer
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
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.

please help me with roots
Answer and Step-by-step explanation:
There aren't any real roots.
This is because the equation isn't factorable. You would have to use the quadratic formula to find the roots, which would be imaginary roots, and not real roots.

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

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.
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]

The probability that a seed will germinate is 0.65. Find the probability that a seed selected at a random will not germinate. *
Answer:
0.35 or 35%
Step-by-step explanation:
The probability that any seed will germinate is said to be 0.65 (or 65%) in the question. This means that the remaining percentage is the probability that the randomly selected seed will not germinate. This is because there is only two possible outcomes to that given scenario, which is it will germinate or not. Meaning that the remaining percentage/probability is that it will not germinate
1 - 0.65 = 0.35 or 35%
