Use the Fundamental Theorem of Calculus to find y′ pls help me
Answer:
Convert to the form of fundamental theorem
[tex]y = \int_{1-6x}^1 \frac{u^3}{1+u^2}du= -\int\limits^{1-6x}_1 {\frac{u^3}{1+u^2} } \, du[/tex]
Step-by-step explanation:
Now, you can apply the theorem, that is [tex]y'= f(1-6x) \times (1-6x)' = -6 \frac{(1-6x)^3}{(1+(1-6x))}[/tex]

Solve and check answer 3(4-5x)=3(4x+3)
Hey there!
3(4 - 5x) = 3(4x + 3)
3(4) + 3(-5x) = 3(4x) + 3(3)
12 - 15x = 12x + 9
-15x + 12 = 12x + 9
SUBTRACT 12x to BOTH SIDES
-15x + 12 - 12x = 12x + 9 - 12
SIMPLIFY IT!
-27x + 12 = 9
SUBTRACT 12 to BOTH SIDES
-27x + 12 - 12 = 9 - 12
CANCEL out: 12 - 12 because it gives you 0
KEEP: 9 - 12 because it helps solve for the x-value
NEW EQUATION: -27x = 9 - 12
SIMPLIFY IT!
-27x = -3
DIVIDE -27 to BOTH SIDES
-27x/-27 = -3/-27
CANCEL -27/-27 because that gives you 1
KEEP: -3/-27 because it helps solve for the x -value
NEW EQUATION: x = -3/-27
SIMPLIFY IT/REDUCE the FRACTION!
x = 1/9
Therefore, your answer is: x = 1/9
Good luck on your assignment and enjoy your day!

The slope is the number in front of the x. And the y-intercept is the number after the x.
A negative y-intercept would be subtracted from the equation.
Answer is B. Y = 7.5x - 2

y = 7.5x - 2
The slope is 7.5
y- intercept is -2
-8 = m/3 + 2
Solve the equation.
m=?
Please explain using 2-step version
-8 = m/3 + 2
Subtract 2 from both sides
-10 = m/3
Multiply both sides by 3
M = -30
Answer:
[tex]m=-30[/tex]
Step-by-step explanation:
[tex]-8=\frac{m}{3}+2[/tex] <-- Given equation
[tex]3(-8)=3(\frac{m}{3}+2)[/tex] <-- Step 1: Multiply both sides by 3 to eliminate the fraction
[tex]-24=m+6[/tex]

Find the measure of angle m
Answer:
36
Step-by-step explanation:
Any triangle have 180 degrees in total.
So 60 + 84 + angle M = 180
144 + angle M = 180
180 - 144 = angle M
angle = 36
let f(x)=3x-2, g(x)=5x+1
fogof(2)
Answer:
f(g(2)) = 29
Step-by-step explanation:
First of all we write the new function defined as the composite function of f and g: f(g(x)) = 3(5x+1) - 2 = 15x + 3 - 2 = 15x -1
Now we can simply "plug in" 2 instead of the x in the function we just obtained: f(g(2)) = 15*2 - 1 = 29
What is 25+25-100+25+25
Answer: 0

Find the quotient 12÷3/8
Answer:
32
Step-by-step explanation:
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator
Thus, the answer to 12 divided by 3/8 in fraction form is:
96 /3
To make the answer to 12 divided by 3/8 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
96 / 3 = 32
The answer is rounded to the nearest two decimal points if necessary.
96/3 can be simplified to 32/1.
32/1 is an improper fraction and should be written as 32.
Hope this helps <3

are:
132114132113111221
AND
11131221141113122113312211
Step-by-step explanation:
I shall explain the pattern below:
431 (just the digits 4, 3, and 1)
141311 (one 4 becomes 14, one 3 becomes 13, one 1 becomes 11 -> looking at each digit of the previous number, 431)
1114111321 (one 1 becomes 11, one 4 becomes 14, one 1 becomes 11, one three becomes 13, two consecutive 1s becomes 21 -> looking at each digit of the previous number, 141311)
311431131211 (three consecutive 1s becomes 31, one 4 becomes 14, 3 more consecutive 1s becomes 31, one 3 becomes 13, one 2 becomes 12, and one 1 becomes 11 -> looking at each digit of the previous number, 1114111321)
NEXT TWO NUMBERS:
one 3 (13), two consecutive 1s (21), one 4 (14), one 3 (13), two consecutive 1s (21), one 3 (13), one 1 (11), one 2 (12), two consecutive 1s (21)
that makes: 132114132113111221
one 1 (11), one 3 (13), one 2 (12), two consecutive 1s (21), one 4 (14), one 1 (11), one 3 (13), one 2 (12), two consecutive 1s (21), one 3 (13), three consecutive 1s (31), two consecutive 2s (22), one 1 (11)
that makes: 11131221141113122113312211
The rule is that the next number is essentially the previous number with the number of times each digit appears consecutively before each digit of the previous number. I know that sounds convoluted. Hopefully it makes enough sense. Let me know if I should explain more fully.
During a sale, a store offered a 10% discount on a stereo system that originally sold for $810. After the sale, the discounted price of the stereo system was marked up by 10%. What was the price of the stereo system after the markup? Round to the nearest cent.

Answer:
$801.9
Step-by-step explanation:
10% of 810 is 81
810-81 = 729
10% of 729 is 72.9, so add that back to get the extra 10%
729+72.9 = 801.9

Find m
∠
K
M
L
∠KML.
Answer:
m∠KML = 35°
Step-by-step explanation:
This is an isosceles triangle because 2 of the sides are equal so we know the 2 unknown angles are equal. The 3 angles of any triangle always add up to 180° so since we know 1 angle is 110° then the 2 unknown angles must add up to 70° (because 180° minus the known 110° leaves us with 70°). Since we know the 2 unknown sides are equal 70° ÷ 2 = 35°. So, m∠KML = 35°

x²- 8x-9=0 i need some help over here
Answer:
(x+1)(x-9)
Step-by-step explanation:
Break the equation: x²- 8x-9=0 into groups:
([tex]x^{2}[/tex]+x)+(-9x-9)
Factor X out of [tex]x^{2}[/tex]+x: x(x+1)
Then Facor -9 out of (-9x-9): -9(x-1)
This means that you can simplify these 2 equations: (x-9) & (x+1)
So your answer is: (x+1)(x-9)
My daughter is having a hard time trying to figure this problem.
Hey there! :-)
First, let's find the slope of the line.
We can do that by using this formula:
Slope=Rise/Run
Where
Rise=how many units we move up
Run=how many units we move left or right.
We move 5 units up and 8 units to the right.
Therefore, the slope is 5/8.
The y-intercept (where the line touches the graph) is -9/8.=
Therefore, the equation of the line is y=5/8x-9/8.
Hope this helps you daughter. Use the comment section to clarify any doubts.

Good luck.
Answer:
a - y=5/8x - 9/8
Step-by-step explanation:
firstly, work out the gradient between those two coordinates
[tex]gradient = \frac{change \: in \: y}{change \: in \: x} [/tex]
[tex]gradient \: = \frac{ - 3 - 2}{ - 3 - 5} = \frac{ - 5}{ - 8} = \frac{5}{8} [/tex]
now, use formula y=mx+c where y is the y coordinate, m is the gradient, x is the x coordinate and c is the y intercept
use any of the two coordinates in the graph. I'll use (5,2)
[tex]y = mx + c[/tex]
[tex]2 = \frac{5}{8} (5) + c[/tex]
[tex]2 = \frac{25}{8} + c[/tex]
[tex]therefore \: c \: is \: - \frac{9}{8} from \: doing \: 2 - \frac{25}{8} [/tex]
now we have the gradient and y intercept
so the equation is
[tex]y = \frac{5}{8} x - \frac{9}{8} [/tex]
