If the cost, C. for manufacturing x units of a certain product is given by C = x2 + 35x + 35, find the number of units manufactured at a cost of $10,235.
Answer: 85 units
Step-by-step explanation:
x^2 +35x + 35 = 10235
-10235 on both sides
x^2 + 35x -10200
Now Factor
( x - 85 ) ( x + 120 )
Now plug in for x using 85 or -120
(85)^2 + 35(85) + 35
7225 + 2975 + 35 = 10235
So 85 is the right answer

integral of x+2/
[tex] \sqrt{x { + 2x + 3}^{2} } [/tex]
Looks like the integral should be
[tex]\displaystyle\int\frac{x+2}{\sqrt{x+(2x+3)^2}}\,\mathrm dx[/tex]
Expand the denominator:
[tex]\displaystyle\int\frac{x+2}{\sqrt{4x^2+13x+9}}\,\mathrm dx[/tex]
Notice that
[tex]u=4x^2+13x+9\implies \mathrm du=(8x+13)\,\mathrm dx[/tex]
In order to use this substitution, expand the integral as
[tex]\displaystyle\frac18\int\frac{8x+13}{\sqrt{4x^2+13x+9}}\,\mathrm dx+\frac38\int\frac{\mathrm dx}{\sqrt{4x^2+13x+9}}[/tex]
In the first integral, use the previously mentioned substitution:
[tex]\displaystyle\frac18\int\frac{8x+13}{\sqrt{4x^2+13x+9}}\,\mathrm dx=\frac18\int\frac{\mathrm du}{\sqrt u}=\frac14\sqrt u[/tex]
[tex]=\dfrac14\sqrt{4x^2+13x+9}[/tex]
In the second integral, complete the square in the denominator:
[tex]4x^2+13x+9=4\left(x+\dfrac{13}8\right)^2-\dfrac{25}{16}[/tex]
Now substitute
[tex]x=\dfrac58\sec t-\dfrac{13}8\implies\mathrm dx=\dfrac58\sec t\tan t\,\mathrm dt[/tex]
so that
[tex]\sec t=\dfrac{8x+13}5[/tex]
Then
[tex]4x^2+13x+9=\dfrac{25}{16}(\sec^2t-1)=\dfrac{25}{16}\tan^2t[/tex]
and the integral becomes
[tex]\displaystyle\frac{\frac{15}{64}}{\frac54}\int\frac{\sec t\tan t}{\sqrt{\tan^2t}}\,\mathrm dt=\frac3{16}\int\sec t\,\mathrm dt[/tex]
[tex]=\dfrac3{16}\ln|\sec t+\tan t|[/tex]
[tex]=\dfrac3{16}\ln\left|\dfrac{8x+13}5+\dfrac{\sqrt{(8x+13)^2-25}}5\right|[/tex]
So, the integral is
[tex]\dfrac14\sqrt{4x^2+13x+9}+\dfrac3{16}\ln\left|\dfrac{8x+13}5+\dfrac{\sqrt{(8x+13)^2-25}}5\right|+C[/tex]

The ratio of the width to the length of a rectangle is 1:3. Which of the following ratios represents a rectangle with:______.
a) 5:7.
b) 6:9.
c) 33:100.
d) 21:63.
The question is incomplete. Here is the complete question
The ratio of the width to the length of a rectangle is 1:3. Which of the following ratios represents a rectangle with this same ratio?
Answer:
21:63
Step-by-step explanation:
The ratio of the width to the rectangle is 1:3
= 1/3
= 0.333333
From the options given we have the following ratios
=5:7
= 5/7
= 0.71428
= 6:9
= 6/9
= 0.666666
= 33:100
= 33/100
= 0.33
= 21:63
= 21/63
= 0.3333333
Hence the ratio which represents the rectangle given above is 21:63

Favorite type of music, choose the correct level of measurement
Answer:
The answer is "Nominal"
Step-by-step explanation:
Some of the data is missing which is defined in the attached file. please find it.
The standard measuring degree is nominal for the favorite type of music because the type of music it can be listening for depends on a variety of factors, like age, social or local environment, etc, and the wrong choice can be defined as follows:
It is wrong because the Ordinal does have a nominal or measuring element, however, the name system allows a ranked or a specific series of variables for all the variables to also be organized. The ratio has the structure infections rate property, as well as the quantities ranges of the variable, provide value, that's why it is incorrect. It is wrong because the internal has the property of ordinal level rate as well as the vector values have significance.3/7➗4/5= How do you solve this problem, step by step?

A marble is selected at random from a jar containing 5 red marbles, 2 yellow marbles & 3 green marbles. What is the probability that a)the marble is red
b)the marble is not yellow
c)the marble is either red or green

Graph the image of the given triangle under a dilation with a scale factor of –4 and center of dilation (0,0).
Step-by-step explanation:
Hey there!
The coordinates of a triangle are;
A (1,2)B (1,-2)C (-2,-2)Scale factor = -4 and centre at (0,0)Now, We have;
P(x,y)----------- P'(kx, ky)
Keep formula;
A(1,2)---------- A'(-4×1 ,-4×2)
= A'(-4, -8)
B(1,-2)------------- B'(-4,8)
C(-2,-2)-------------C'(8,8)
[ The A' should be kept in (-4,-8). There was no place in this graph so, i kept it just below -7. Please while plotting remember to keep it on "-8".]

Melissa used her credit card to buy a $745 refrigerator. She kept the refrigerator for exactly nine years, during which time it consumed an average of $0.19 of electricity every day. Melissa’s credit card has an APR of 16.84%, compounded monthly. Melissa paid off her refrigerator by making identical monthly payments for four years. If she made no other purchases with her card, what percentage of the lifetime cost of the refrigerator did the electricity make up? (Assume that two of the years were leap years, and round all dollar values to the nearest cent.) a. 59.17% b. 18.48% c. 66.99% d. 37.77%
Answer:
37.77
Step-by-step explanation:
P= PV x i / 1- (1+i)^-n
PV = 745
I = .1684 / 12 = .01403
N = 4 x 12 = 48
.19 x (365 x 9) = 624.53
21.4338469 x 48= 1028.12
624.53 / (624.53+1028.12) = 37.77
The percentage of the lifetime cost of the refrigerator did the electricity make up is : d. 37.77%.
Percentage of the lifetime costUsing this formula
P= Pv x i / 1- (1+i)^-n
Where:
Present value = 745
Interest= .1684 / 12 = .01403
Number of months = 4 x 12 = 48
Hence:
Percentage=.19 x (365 x 9)/(.19 x (365 x 9)+(21.4338469 x 48)
Percentage=624.53 / (624.53+1028.12)
Percentage= 37.77%
Inconclusion the percentage of the lifetime cost of the refrigerator did the electricity make up is : d. 37.77%.

Which of the following represents the solution to the inequality 4x - 2 ≤ 10?
Answer:
Step-by-step explanation:
Okay so solving an inequality is essentially the same as solving an expression, just with a different symbol.
We can first separate the x to the left and whole numbers to the right side.
TIP INPORTANT: Put your variable numbers on the left side and your whole numbers which are the numbers without variables on the right side
so,
4x ≤ 10 + 2
which is,
4x ≤ 12, therefore,
x ≤ 3.
Hope this helps!
The solution is x ≤ 3
What is an Inequality Equation?
Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. Where as in an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
4 x - 2 ≤ 10
Adding 2 on both sides , we get
4 x ≤ 12
Divide by 4 on both sides , we get
x ≤ 3
Hence , the solution is x ≤ 3

I need to find the surface area of the square pyramid!
(I know I'm stupid lol)
Answer:
L = 260 cm^2
Step-by-step explanation:
height h = 12 cm
slant height s = 13 cm
side length a = 10 cm
lateral edge length e = 13.928388277184 cm
1/2 side length r = 5 cm
volume V = 400 cm^3
lateral surface area L = 260 cm^2
base surface area B = 100 cm^2
total surface area A = 360 cm^2
Genda: h = height
s = slant height
a = side length
e = lateral edge length
r = a/2
V = volume
L = lateral surface area
B = base surface area
A = total surface area

Answer the question marks, and tell me what sequence number 8 is.
Answer:
f[1] = 60; f[n+1] = f[n] -30f[n] = 60 -30(n-1)Step-by-step explanation:
You observe that each term is 30 less than the previous one. This is the recursive rule. It also means the sequence is arithmetic with a common difference of -30.
Recursive equation
f[1] = 60; f[n+1] = f[n] -30
__
Explicit equation
The general form of the explicit equation is ...
f(n) = f(1) +d(n -1)
Here, we have f(1) = 60 and d = -30, so your equation is ...
f(n) = 60 -30(n -1)
