The value of 0e^0d0 is -1 if the integral in this exercise converges after applying limit.
What is convergent of a series?A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums getting closer and closer to a certain number.
We are assuming the:
[tex]=\int\limits^0_{-\infty} {\theta e^{\theta}} \, d\theta[/tex]
Applying limit;
[tex]=\lim_{n \to \infty} \int\limits^0_{-n} {\theta e^{\theta}} \, d\theta[/tex]
After solving the integral:
[tex]=\lim_{n \to \infty} (e^{\theta})|^0_-_p[/tex]
= -(1-0)
= -1
Thus, the value of 0e^0d0 is -1 if the integral in this exercise converges after applying limit.

Step-by-step explanation:
Demand and supply in a market are described by the following equations: qd = 66-3p qs = -4 2p find the equilibrium price and quantity
The equilibrium price is $14 and the quantity is 24.
What is the equilibrium price?Equilibrium is the place in the market where there is no trend for change.
Buyers’ and sellers’ plans accord, and consequently quantity demanded equals quantity supplied.
The equilibrium price occurs when the quantity demanded equals the quantity supplied.
The demand and supply functions are, respectively:
Demand and supply in a market are described by the following equations: QD = 66-3p and qs = -4 + 2p.
The equilibrium price and quantity are;
QD = QS
66-3p = -4 + 2p
66 + 4 = 2p + 3p
70 = 5p
p = 70/5
p = 14
QD = 66-3p
QD = 66-3 × 14
QD = 66- 42
QD = 24
Hence, the equilibrium price is $14 and the quantity is 24.

the length of the hypotenuse of a 45°-45°-90° triangle with a leg of 12, what the length
Answer:
The length of the other two legs are 6√2.
since the hypotenuse is one of the legs multiplied by √2.
dividing the hypotenuse by √2 will get the length of one leg. since it is a 45 45 90 triangle, the length of the two legs are the same.
12/√2= 12√2/2= 6√2
Use DESMOS: What is the equation
that represents a line that is
perpendicular to the graphed line and
passes through the point (-6, 6)?
y=mx+c
I picked the points (0, -4) and (-2,-10) to find the gradient of the line
M= rise/run
= 6/2
=3
Y-intercept is at - 4
Y= 3x - 4 is equation of the line given
Reciprocal of 3 is 1/3
(m1 x m2 = - 1)
So, to make - 1, our second gradient should be negative.
Gradient of the perpendicular line will be - 1/3
Y= - 1/3x + c
Substitute value of x & y into the equation
(-6,6) means x = - 6, y = 6
y = - 1/3x +c
6 = - 1/3 x - 6 + c
6 = 2 + c
-2
4 = c
Thus, final equation we're after will be:
y= - 1/3x + 4

A filing cabinet measures 5 feet is 18 inches wide and 2 feet deep what is the volume of the filing cabinet
Answer:
15 feet
Step-by-step explanation:
From the question above,we are asked to find the volume of a cabinet with the following dimensions:
Height is five feet
Width is eighteen inches
And a depth of two feet.
Here it is quite obvious that we ate dealing with a cuboidal object since its dimensions differ from one another.
So volume of a cuboid as we all know is :
Length multiplied by width and then height
We should head straight away to the calculations, but we need to remember that the width is in inches and needs to be converted to feet
1 inch = 1/12 feet
18 inches = 18× 1/12
= 1.5 feet
L×W×H
= 1.5×5×2
= 15 feet

the vertex of triangle DEF are D(1,3) ;E(-1,0) ;F(2,-1) find the coordinate of orthocenter for this triangle
please with clear explanation I will give brainliest
Answer:
[tex]\sf \left(\dfrac{1}{11},\dfrac{3}{11}\right)[/tex]
Step-by-step explanation:
The orthocenter is the point of intersection of the altitudes of a triangle.
(The altitude is the line that passes through the vertex and is perpendicular to the side opposite the vertex).
**Refer to attached diagram**
DC, EA and FB are the perpendicular lines drawn from the three vertices D, E and F.
[tex]\sf Let\:(x_1,y_1)=D\implies(x_1,y_1)=(1,3)[/tex]
[tex]\sf Let\:(x_2,y_2)=E\implies (x_2,y_2)= (-1,0)[/tex]
[tex]\sf Let\:(x_3,y_3)= F\implies (x_3,y_3)=(2,-1)[/tex]
G (x, y) is the intersection point of the three altitudes of the triangle, i.e. the orthocenter.
To find the point of intersection (orthocenter), we need to create linear equations for the altitudes, then equate them to find the point of intersection.
We only need to work with 2 altitudes.
Calculate the slopes of two sides of the triangle.
[tex]\sf \implies Slope\:of\:EF=\dfrac{y_3-y_2}{x_3-x_2}=\dfrac{-1-0}{2-(-1)}=-\dfrac{1}{3}[/tex]
[tex]\sf \implies Slope\:of\:DF=\dfrac{y_3-y_1}{x_3-x_1}=\dfrac{-1-3}{2-1}=-4[/tex]
As the slopes of the altitudes are perpendicular to the slopes of the sides:
[tex]\textsf{Slope of DC}=\sf \dfrac{-1}{\textsf{slope of EF}}=\dfrac{-1}{-\frac{1}{3}}=3[/tex]
[tex]\textsf{Slope of EA}=\dfrac{-1}{\textsf{slope of DF}}=\sf \dfrac{-1}{-4}=\dfrac{1}{4}[/tex]
Using point D (1, 3) and the slope of DC to create a linear equation for DC using the point-slope form of a linear equation:
[tex]\sf \implies y-y_1=m(x-x_1)[/tex]
[tex]\sf \implies y-3=3(x-1)[/tex]
[tex]\implies \sf y=3x[/tex]
Using point E (-1, 0) and the slope of EA to create a linear equation for EA using the point-slope form of a linear equation:
[tex]\sf \implies y-y_1=m(x-x_1)[/tex]
[tex]\sf \implies y-0=\dfrac{1}{4}(x-(-1))[/tex]
[tex]\sf \implies y=\dfrac{1}{4}x+\dfrac{1}{4}[/tex]
To find the x-value of the point of intersection (the orthocenter), equate the equations and solve for x:
[tex]\implies \sf 3x=\dfrac{1}{4}x+\dfrac{1}{4}[/tex]
[tex]\implies \sf \dfrac{11}{4}x=\dfrac{1}{4}[/tex]
[tex]\implies \sf 11x=1[/tex]
[tex]\implies \sf x=\dfrac{1}{11}[/tex]
To find the y-value of the point of intersection (the orthocenter), substitute the found value of x into the equation for line DC:
[tex]\implies \sf y=3\left(\dfrac{1}{11}\right)[/tex]
[tex]\implies \sf y=\dfrac{3}{11}[/tex]
Therefore, the orthocenter is at point:
[tex]\sf \left(\dfrac{1}{11},\dfrac{3}{11}\right)[/tex]
In an isosceles triangle the length of the base is 10 cm
The computation shows the radius of the circle that is inscribed in the isosceles triangle will be 3.33cm.
How to calculate the radius?From the information given, the isosceles triangle the length of a base is 10 cm and the length of a leg is 13 cm.
Let A = area of the triangle
Let S = semi perimeter of the triangle.
The radius will be: = A/S
where,
[tex]S = \dfrac{(a + b + c)}{2} = \dfrac{(13 + 13 + 10)}{2} = 18[/tex]
The radius will be:
[tex]=\dfrac{(\sqrt{18} - \sqrt{13})(\sqrt{18} - \sqrt{13})(\sqrt{18} - \sqrt{10})} { 18}[/tex]
= 3.33cm
In conclusion, the radius is 3.33cm.

The lines that appear tangent are tangent. What is the value of x, to the nearest tenth.
Answer:
x ≈ 10.7
Step-by-step explanation:
Is given in the picture that x is the radius of the circle.
The radius of a circle and the tangent line to the circle form a right angle, therefore our triangle is a right triangle.
We can apply the Pythagorean Theorem to find one equation that will have one unknown x.
(x+12)² = x² +20² , use that (a+b)² = a²+b²+2ab
x²+12²+2·x·12 = x² +20², subtract x² from both sides of the equation
12² + 24x = 20², subtract 12² from both sides of the equation
24x = 20²-12², raise to power and combine like terms
24x = 256, divide by 24 both sides of the equation
x = 10.6666666..., round to the nearest tenth

Scott is reading two books at the same time to prepare for a report he is writing. So far, he has read 407 of the total number of 557 pages, which is Three-fifths of the shorter book and StartFraction 5 Over 6 EndFraction of the longer book. Which system of equations can be used to determine the total number of pages in the shorter book, x, and the total number of pages in the longer book, y?
x + y = 557 and Three-fifths x + five-sixths y = 407
x + y = 407 and Three-fifths x + five-sixths y = 557
x + y = 557 and Five-sixths x + three-fifths y = 407
x + y = 118 and StartFraction 4 Over 9 EndFraction x + two-thirds y = 118
An equation is formed of two equal expressions. The correct option is x+y=557 and Three-fifths(x)+five-sixths(y)=407.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the total number of pages in the shorter book be represented by x, and the total number of pages in the longer book be represented by y.
Given the total number of pages of the shorter book and the longer book is 557. Therefore, the equation can be written as,
x+y =557
Also, Scott reads Three-fifths of the shorter book and StartFraction 5 Over 6 EndFraction of the longer book, which is equal to 407 pages. Therefore,
(3/5)x + (5/6)y = 407
Hence, the correct option is x+y=557 and Three-fifths(x)+five-sixths(y)=407.
