Step-by-step explanation:
Let y = x² In(x).
dy/dx the lesson is differentiate products
Answer:
dy/dx = x(1+2lnx)
Step-by-step explanation:
Given y = x² In(x).
dy/dx = Udv/dx + Vdu/dx
Let U = x², V = lnx
du/dx = 2x
dv/dx = 1/x
Substitute into the formula;
dy/dx = x²(1/x) + lnx(2x)
dy/dx = x + 2xlnx
dy/dx = x(1+2lnx)
A rectangular prism has a length of 7 cm, a width of 4 cm, and a height of 2 1/2cm.
The prism is filled with cubes that have edge lengths of 1/2 cm.
How many cubes are needed to fill the rectangular prism?
Enter your answer in the box.
To fill the rectangular prism,
cubes are needed.
Answer:
560 cubes
Step-by-step explanation:
Volume of prism: lwh, 7*4*2.5, 70cm!
Volume of cubes: lwh, 0.5*0.5*0.5, 0.125cm!
70cm/0.125cm=560 cubes.
Answer:
560 cubes
Step-by-step explanation:
first solve the volume of the rectangular prism
V = l x w x h
where l is the length
w is the width
h is the height
V = 7 x 4 x 2.5
v = 70 cu cm
then solve the volume of the box
v = e^3
v = 0.5^3
v = 0.125
number of cubes = 70 / 0.125
number of cubes = 560 cubes

Tony is trying to find the solutions to the quadratic equation 3x2 + 24x - 15 = 0 by factoring and
has come to you for help. Explain why Tony would need to use a method other than factoring to find
the solutions to this equation.
DO NOT SOLVE and be specific in your explanation.
В І у
0 / 1000 Word
Answer:
You would either need to complete the square, use the quadratic equation, or another method because when reduced by the common factor, the constant term c is prime which means that it is only divisible by one and itself. Because the possible rational factors determined by c do not add up to the b term, it cannot be factored.
Explanation:
3x² + 24x - 15 = 0
3(x² + 8x - 5) = 0
[find the greatest common factor between each term and move the coefficient outside of the expression; in this case it's 3 since 3 fits into numbers 3, 24, and -15 so that it cannot be reduced further]
Then you can either use the box or pq method (since a is 1) to find working factors.
x² + bx + c → (x + p)(x + q).
p + q = b.
pq = c.
In this case with 3(x² + 8x - 5), b is 8 and c is -5.
This means we need two numbers that add up to 8 and multiply to -5.
Since -5 is prime, our only options are ±1 for p and ∓5 for q. This is because these are the only factors which multiply to -5.
1 + -5 = -4 ≠ 8
-1 + 5 = 4 ≠ 8.
Since we cannot find rational solutions, this cannot be factored, and so we must use another method.
Why is m..?
somebody help please
Answer:
The last one
Step-by-step explanation:
The fast reason why - all the other scenarios require 3 lines: 2 lines both parallel to a 3rd, or 2 lines cut by a transversal line, etc. The diagram only shows 2 lines. So the right answer must be the one that doesn't require a third line to be present. :)
The longer answer why - See how angles 2 & 3 have the same style of arc? That is telling you they are of equal measure. So together they are a straight angle, 180°. And they are equal to each other, so 2x = 180° --> each one must be a 90° angle.
Wherever two lines cross, if one angle is a right angle, all 4 angles at the intersection also must be right angles, so everything is perpendicular.

You know that a rope is no more than 100 feet long. You need to cut the rope into three pieces the second piece is to be three times as long as the first piece, and the third piece must be 18 feet long. What is the maximum length of the second piece?
Answer:
hi
Step-by-step explanation:
The rope is originally 100 ft. long. The first piece is 32 ft., leaving 100–32, or 68 ft.
Let n be the second piece, and n-30 be the third piece. Then:
n+n-30=68
2n=98
n=49
n-30=19
The second piece is 49 ft. long; the third piece is 19 ft. long ……..

23rd term of -11,-7,-3 in arithmetic sequence
Answer:
The 23rd term for the sequence is -99
Step-by-step explanation:
We can use an explicit rule to find the 23rd term.
Given Info:
=> Sequence: -11,-7,-3
=> f(1) = -11
=> Common difference (d) = -4
Explicit rule: f(1) + d(n-1)
So,
-11 -4 (n-1)
Substitute 23 for n
=> -11 - 4(23-1)
=> -11 - 4(22)
=> -11 - 88
=> -99
hope this helps and is right :)

Describe the slope of the line.
The slope is
Find the slope.
m =
help please
Step-by-step explanation:
In order to find the slope, we must know the formula needed.
[tex]\frac{y2}{x2} -\frac{y1}{x1} =m[/tex]
Using 2 given points, we can subtract both and receive our final answer.
Points that are provided:
(4, 3)(1, -1)Substitute the given points into the formula format.
Then, solve.
[tex]\frac{3}{4} -\frac{-1}{1} =\frac{4}{3}[/tex]
m = 4/3
The slope is positive. Meaning that the slope is increasing for the value of y.

9514 1404 393
Answer:
1. 6.1 to 10.3
2. 9.6 hours
3. 7.5 hours
Step-by-step explanation:
1. The empirical rule or the supplied chart will tell you that μ ±3σ of the distribution is within 99.7% of the mean. Here, that is ...
8.2 ±3(0.7) = 8.2 ±2.1 = [6.1, 10.3]
The range of hours is 6.1 to 10.3 hours.
__
2. 2.5% of the distribution is above μ +2σ, or ...
8.2 +2(0.7) = 9.6 . . . hours
__
3. The bottom 16% of the distribution is below μ -σ, or ...
8.2 -0.7 = 7.5 . . . hours
You have a restaurant bill of $46.32. If you are taxed 7 1/2 and decide to tip your server 20%, how much is your total?
a.
$59.75
b.
$59.05
c.
$58.92
d.
$58.87
Answer:
The correct answer is B. $59.05.
Step-by-step explanation:
Given that I have a restaurant bill of $ 46.32, if I am taxed 7 1/2 and decide to tip my server 20%, to determine how much is my total, the following calculation must be performed:
1/2 = 0.5
46.32 + (46.32 x 0.075) + (46.32 x 0.2) = X
46.32 + 3.474 + 9.264 = X
49.79 + 9.26 = X
59.05 = X
Thus, the total amount that I must pay is $ 59.05.
