Answer:
Step-by-step explanation:
y = 3(4x + 1)^1/2 - 2x
dy/dx = 3*1/2(4x + 1)^-1/2 * 4 - 2
= 4 * 1.5 (4x + 1)^-1/2 - 2
= 6(4x + 1)^-1/2 - 2
= [6/√(4x + 1)] - 2
y = 3(4x + 1)^1/2 - 2x
∫3(4x + 1)^1/2 - 2x . dx
= 3 * 1/4 * (4x + 1)^3/2 / 3/2 - x^2 + C
= 3/4 * 2/3 (4x + 1)^3/2 - x^2 + C
= 1/2((4x + 1)^3/2 - 2x^2) + C.

Find the measure of b.
A. 70
B. 110
C. 75
D. 100
Answers
Answer: C. 75
Concept:
Here, we need to know the idea of quadrilaterals in a circle.
The opposite angles of quadrilaterals in a circle (cyclic quadrilaterals) are supplementary, meaning they add up to 180°
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
Given information
The opposite angle of b = 105°
Given expression
b + opposite angle of b = 180°
Substitute values into the expression
b + 105 = 180
Subtract 105 on both sides
b + 105 - 105 = 180 - 105
b = 75°

Find three consecutive integers that have the sum of -402
Answers
Answer:
-135, -134, -133
Step-by-step explanation:
Hi there!
Let x be equal to the first integer in the set of three consecutive integers.
Let x+1 and x+2 be the consecutive integers.
We're given that they have a sum of -402.
We can construct an equation:
[tex](x)+(x+1)+(x+2)=-402[/tex]
Combine like terms:
[tex]x+x+1+x+2=-402\\x+x+x+1+2=-402\\3x+3=-402\\3x=-405\\x=-135[/tex]
Therefore the first integer is -135.
The next two consecutive integers after -135 is -134 and -133.
Therefore, the three consecutive integers are -135, -134 and -133.

If 2x - 4= 16 for some value of x, then
what is the value of x + 2 for the same
value of x?
Answers
Answer:
12
Step-by-step explanation:
2x - 4= 16
Divide by 2
2x/2 -4/2 = 16/2
x -2 = 8
Add 4 to each side
x-2+4 = 8+4
x+2 = 12
Step 1:
2x - 4 = 16
+4 = +4
2x = 20
2x/2 = 20/2
x = 10
Step 2:
x + 2
10 + 2 = 12
So your answer is 12.

A line is parallel to the x-axis and passes through the point (-5,4)
What is the equation of that line, the slope of that line, and what would be the slope of a line perpendicular to that given line?
Answers
9514 1404 393
Answer:
y = 4slope: 0slope of perpendicular: undefinedStep-by-step explanation:
The x-axis is a horizontal line. As such, it has a slope of zero. The equation of a horizontal line is ...
y = constant
__
For the line through (-5, 4), the constant must match the y-coordinate: 4. The equation is ...
y = 4
As we said above, the slope of that horizontal line is zero.
The perpendicular line will be a vertical line of the form x=constant. The slope of a vertical line is undefined.

The ratio of vowels to Constance to a paragraph is 3:5 there are 280 letters in the paragraph how many are vowels how many are consonant
Answers
Answer:
280/8 = 35 "sets"
35*3 = 105 Constance
35*5 = 175 vowels
Step-by-step explanation:
There are 105 consonants and 175 vowels in a paragraph.
What is vowels and consonants?Vowels (such as a, e, I o, and u) and consonants combine to form words (the rest of the alphabet). The letter "y" is a little odd since it can function as a vowel or a consonant depending on the context. Spelling will be made easier for you if you understand how vowels and consonants combine to form words and sounds.
a speaking sound made by people when their teeth, tongue, or lips obstruct the breath from leaving their mouths. grammar. Except for the English vowels a, e, I o, and u, a consonant is a letter that represents a sound made in this way.
Given:
The ratio of vowels to Constance to a paragraph is 3:5 there are 280 letters in the paragraph.
First to find the number of sets in the paragraph as
[tex]\frac{280}{3+5} = \frac{280}{8} = 35[/tex]
Therefore, there are 35 sets in the paragraph.
So, 35 x 3 = 105 are consonants and
35 x 5 = 175 are vowels.

a. What would her machine do to an input of 5? What about -1? What about x?
b. Write an equation for Terri's machine
Answers
Answer:
a) An input of 5 gives an output of 14. An input of -1 gives an output of -4.
An input of x gives an output of 3x - 1
b) y = 3x - 1
Step-by-step explanation:
The pattern is that you multiply the number by 3 then subtract 1.
3*3 - 1 = 9 - 1 = 8
10 * 3 - 1 = 30 - 1 = 29
20 * 3 - 1 = 60 - 1 = 59
So:
a)
For an input of 5,
5 * 3 - 1 = 15 - 1 = 14
For an input of -1:
-1 * 3 - 1 = -3 - 1 = -4
For an input of x:
x * 3 - 1 = 3x - 1
So the equation is
b) y = 3x - 1
where x is the input value.

solve for x in the problem below and show all work
7x - 5x/3 (20/x - 8) -48=0
Answers
Let’s work this out step by step.
The first thing you want to do is move that 48 to the other side. To do that, add 48 to both sides:
7x-5x/3(20x-8)=48
Now, the equation isn’t equal to zero… so it is solvable! Remember in order of operations: PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction. So, let’s start by multiplying the (-5x/3) by the components inside the parentheses to get rid of the parentheses altogether!
7x-100x/3x+40x/3=48
Since both the numerator and denominator have an “x” in them in “100x/3x”, you can cancel out the “x”s to just get 100/3, which is 33.333333
7x-100/3+40x/3=48
Let’s get rid of that 100/3 by adding it to both sides.
7x+40x/3=81.33333333333
Transform 7x to a fraction that can be added to 40x/3 (common denominators)
7x=7x/1
7x/1* (3/3)= 21x/3
Now, add the two fractions together
21x/3+40x/3= 61x/3
61x/3=81.333333333
Get rid of the 3 by multiplying on both sides:
61x= 244
Divide by 61 to get x
X=4
