Identify the function's local and absolute extreme values, if any, saying where they occur. f(x) = x^3 + 4x^2 - 3x - 4 A) local maximum at x = -1/3; local minimum at x = 3 B) local maximum at x = -1; local minimum at x = 1 C) local maximum at x = -3; local minimum at x 1/3 D) local maximum at x = -1; local minimum at x = 1
Answer: C) local maximum at x = -3; local minimum at x = 1/3
Step-by-step explanation:
Given the function:
f(x) = x^3 + 4x^2 - 3x - 4
Set f'(x) = 0
f'(x) = 3x² + 8x - 3
f'(x) = 0
3x² + 8x - 3 = 0
Using the quadratic function calculator :
x = - 3 or x = 1/3
Critical points = - 3 ; 1/3
To find the maximum and minimum points :
f''(x) = 6x + 8
Substitute the values of X in
At x = - 3
6(-3) + 8
-18 + 8 = - 10
At x = 1/3
6(1/3) + 8
2 + 8 = 10
Value of f''(x) at - 3 is negative, hence - 3 is the maximum point
Value of f''(x) at 1/3 is positive , hence 1/3 is the minimum point

A class of 128 students from civil, mechanical and electrical engineering backgrounds is divided into 2 sections (sections A and B). Section A contains of 18 civil engineers and a total of 50 students. Section B contains 44 mechanical engineers. There are a total 40 civil engineers and 60 mechanical engineers in the class. What is the probability that a random electrical engineering student is from section A
Answer:
The probability is 0.5714
Step-by-step explanation:
This is a probability question. We are interested in calculating the probability that a random electrical engineering student is from section A.
Mathematically the probability will be;
Number of electrical engineering students in section A/ Total number of electrical engineering students in both sections
Total number of electrical engineering students = 128 - 60 -40 = 28
Now let’s calculate the number of electrical students from section A
Number of mechanical and electrical = 50-18 = 32
Now, there are a total of 60 mechanical engineers and 44 in B; So the number of mechanical engineers in A = 60-44 = 16
So the number of electrical engineers in A = 32-16 = 16
So the probability will be;
16/28 = 4/7 = 0.5714

A shopper paid 11/100 of a dollar for 1/16 of a kilogram of nails. What was the rate in dollars per
kilograms?
Answer:
[tex]Rate = \$1.76/kg[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{16}kg[/tex] of nails costs [tex]\$ \frac{11}{100}[/tex]
Required
Determine the rate
The rate, in this case, will be calculated as:
[tex]Rate = \frac{amount}{weight}[/tex]
[tex]Rate = \frac{\frac{11}{100}}{\frac{1}{16}}[/tex]
This gives
[tex]Rate = \frac{11}{100}/\frac{1}{16}[/tex]
[tex]Rate = \frac{11}{100} * 16[/tex]

Two balls are to be pulled from a vase that contains 7 red balls 9 green balls and 2 black balls. After the first ball Is drawn, it is not the replaced. What is the probability that two black balls are chosen from the vase?
Answer:
[tex]\frac{1}{153}[/tex]
Step-by-step explanation:
There are a total of 7 + 9 + 2 = 18 balls in the vase, therefore, when not replacing the first ball, there would be 18 · 17 = 306 ways to pull 2 balls. There are 2 ways to choose the first black ball and then 1 way to choose the second black ball so there are 2 · 1 = 2 ways to choose 2 black balls. Therefore, the probability is 2 / 306 = [tex]\frac{1}{153}[/tex].
0.4x+3=0.2(3x+1)−x someone plz help
Answer:
x =-3.5
Step-by-step explanation:
0.4x+3=0.2(3x+1)−x
Distribute
.4x +3 = .6x+.2 -x
Combine like tersm
.4x+3 = -.4x+.2
Add .4x to each side
.4x+3 +.4x = -.4x +.2 +.4x
.8x +3 =.2
Subtract 3 from each side
.8x+3-3 = .2-3
.8x = -2.8
Divide each side by .8
.8x/.8 = -2.8 /.8

The lesser milk the mother had made her chocolate more chocolatery, and you can see that she has a 0.2 more than the father
Answer:
The correct answer is Nell's mom.
Step-by-step explanation:
Nell's mom makes chocolate syrup with 30 ml for every chocolate syrup for every 2 ounces of milk.
Nell's dad adds 65 ml of chocolate syrup for every 5 ounces of milk.
To compare who makes a more chocolaty drink we need to have same amount of milk.
Least common multiple of 2 and 5 is given by 10.
Thus in 10 ounces of milk, Nell's mom adds 30 × 5 = 150 ml of chocolate syrup.
In 10 ounces of milk, Nell's dad adds 65 × 2 = 130 ml of chocolate syrup.
Thus on comparison we can say Nell's mom adds more chocolate syrup and hence makes a more chocolaty milk.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.
Here are the total working hour,
= 4:00 + 4:45
= 8:45 hours or (8 + 3/4) hours
Wage per hour = $13/hour
