The general solution of the given non homogeneous
equation is
y(t)=c₁[tex]e^{-t}[/tex] +c₂[tex]e^{t}[/tex] - t
A non-homogeneous system of equations is a system in which the vector of constants on the right-hand side of the equal sign is non-zero.
Given:-General solution for the equation: [tex]y^{"} - y^{'} = t[/tex], [tex]y_{p} (t) = - t[/tex]
Explanation:-Consider the equation [tex]y^{"} - y^{'} = t[/tex] . The corresponding homogeneous equation has the associated auxiliary equation [tex]r^{2} -1 =0[/tex] which has [tex]r^{} =-1[/tex] and [tex]r^{} =1[/tex] as solutions.
The solution of an n-order differential equation depends on an algebraic equation of degree n called the characteristic equation (or auxiliary equation) in mathematics.
Hence the general solution for a homogeneous equation is
y(t) = [tex]-t[/tex]+[tex]c[/tex]₁[tex]e^{t}[/tex]+[tex]c[/tex]₂[tex]e^{-t}[/tex]
Combining the general solution [tex]y(t)=c[/tex]₁[tex]e^{t}+c[/tex]₂ [tex]e^{t}[/tex] with the particular solution of [tex]y_{p} (t) =-t[/tex] of [tex]y'-y"=t[/tex], we find that the general solution to[tex]y"-y'=t[/tex] is [tex]y(t)=c[/tex]₁[tex]e^{-t}+c[/tex]₂[tex]e^{t}[/tex]
The general solution of the given non homogeneous equation is
y(t)=c₁[tex]e^{-t}[/tex] +c₂[tex]e^{t}[/tex] - t

En Cartagena de cada 10 personas 4 tienen una enfermedad, a este ritmo ¿cuántas personas se contagiarán si son 400 personas?
porfa para ya
ayudaaaaaaa
Answer:
Se contagiarian 160 personas.
Step-by-step explanation:
Para este problema debenos usar la siguiente regla de tres:
[tex]\frac{10(personas)}{4(enfermas)}=\frac{400(personas)}{x(enfermas)}[/tex]
Ahora, debemos despejar x de la ecuacion de arriba.
[tex]x=\frac{400(personas)*4(enfermas)}{10(personas)}[/tex]
[tex]x=160(enfermas)[/tex]
Por lo tanto, se contagiarian 160 personas.
Espero te haya sido de ayuda!
HELP, thanks, If a triangle has a side length of 8 inches, and another side length of 5 inches, which of the
following choices for the third side length will make a triangle?
a. 7 inches
b. 2 inches
c. 13 inches
d. 15 inches
Answer:
a. 7
Step-by-step explanation:
So a triangle a two sides that will always sum up to be greater than the third side.
Meaning:
a + b > c
a + c > b
b + c > a
So here, we're given a and b:
8 + 5 > c
8 + c > 5
5 + c > 8
Plug in the values:
13 > 7
15 > 5
12 > 8
These are all true, so it's probably 7.
13 > 2
10 > 5
7 > 8 This one is not true, so not 2.
13 > 13 This is not true, so not 13.
If not 13, we can't go any higher and so it can't be 15.

Step-by-step explanation:
Donna borrowed $10, 500 at a simple interest rate of 4% for 3 years to buy her new car. How much interest would Donna pay and how much is the car altogether?
Donna borrowed $10,500 at a simple interest rate of 4% for 3 years to buy her new car. How much interest would Donna pay and how much is the car altogether ?
Answer:-Given:-[tex] \bullet [/tex] Principal (P) = $10,500
[tex] \bullet [/tex] Rate of interest (r) = 4%
[tex] \bullet [/tex] Time (t) = 3 years
To Find:-Interest of Donna and amount of car altogether.
Solution:-We know,
[tex] { \boxed{\rm \red {I \: = \frac{Prt}{100}}}} [/tex]
[tex] \therefore [/tex] I = [tex] \frac{10,500 \: × \: 4 \: × \: 3}{100} [/tex]
I = [tex] \frac{126,000}{100} [/tex]
I = $1260
Now,
Amount of the car = $ (10,500 + 1260)
= $ 11,760
$1260 interest would Donna pay and $11,760 is the car altogether. [Answer]Step-by-step explanation:
We know that Interest = Principal×Rate×Time/100
So,
10,500×4×3/100
= 10,500×3/25 (by cancelling 100 by 4)
=31500/25
= 1260
Therefore,

Can you solve the inequalities 9.50(70+x)≥1000
Answer: x_>(70+x_>)1000
Step-by-step explanation:
Answer:
35.26315789
Step-by-step explanation:
Question: 9.5(70+x)≥1000
70+x≥1000/9.5
(divide by 9.5 into both sides)
70+x≥105.2631579
x≥105.2631579-70
(minus 70 into both sides)
x≥670/19
x≥35.26315789

Marcello sells coupon books to his neighbors. 4 neighbors each buy 2 coupon books. There are 8 coupons in each book. What is the total number of coupons that all of his neighbors will get? Enter your answer in the box.
Answer:
64
Step-by-step explanation:
Marcello sells coupon books to his neighbors
4 neighbors each buy 2 coupon books
Each book have 8 coupons
Therefore the total number of coupons that all neighbors will get can be calculated as follows
Each neighbor will get 16 coupon
Hence the whole neighbors will get
16×4
= 64 coupons
solve for x by finding the missing side of the triangle. Round your answer to the nearest tenth
Answer:
i thought i had the answer but then i got it wrong im sorry
Step-by-step explanation:
Answer:
Step-by-step explanation:
Remark
The side opposite (the side not connected to the angle) and the hypotenuse relate the sine
Equation
Sin(y) = opposite / hypotenuse
Solution
y = 41 degrees
hypotenuse = 12
x = ?
Sin(41) = x / 12 Multiply both sides by 12
12 Sin(41) = x
Sin(41) = 0.6561
12 * 0.6561 = x
x = 7.8727

The work of a student to solve the equation 2(4x - 4) = 8 + 4x + 4 is shown
below:
Step 1. 2(4x - 4) = 8 + 4x + 4
Step 2. 6x - 6 = 12 + 4x
Step 3. 6x - 4x = 12 + 6
Step 4.2x = 18

Answer:
Step-by-step explanation:
To get the correct answer, you can count the total number of shaded tenths and the total number of shaded hundredths and then regroup.
There are 9 shaded tenths and 18 shaded hundredths. Regroup 10 hundredths into 1 tenth to get 10 tenths and 8 hundredths. Then regroup the 10 tenths in one whole, giving you 1 whole and 8 hundredths. The product is 1.08.
Another way to get the answer is to count the total number of shaded hundredths. There are 108 hundredths. Regroup 100 of them as one whole, giving you 1 whole and 8 hundredths.

Answer and Step-by-step explanation:
The answer to this question is 21.
We can easily find the height of the triangle by going to the bottom point of the triangle and counting up each line.
The height is equal to 6.
When we create this line for the height, it sections off two triangle, one with a side of 4 and the other with a side of 3.
To find the area of a triangle, we must Multiply the side lengths together, then Divide by 2.
Triangle 1
4 × 6 = 24
24 ÷ 2 = 12
Triangle 2
3 × 6 = 18
18 ÷ 2 = 9
Now, we add together the areas to get the area of the full triangle.
12 + 9 = 21.
The area of the triangle is 21 [tex]cm^2[/tex].

PLSS HELP ME I AM GOING TO CRY IF I DONT GET THIS ANSWER PLSS HELP ME What is the slope-intercept equation of the line below?
Answer:
y = -3x + 4
Step-by-step explanation:
Hey!
==================================================================
Slope-Intercept Form: y - mx + b, where m is the slope and b is the y-intercept (point where x =0).
Since we know that the slope is -3, we substitute that in for m.
⇒y = -3x + b
Now, we know the y-intercept is 4, so we substitute that in for b:
⇒y = -3x + 4

The correct answer is B Fitteen is less than r
To translate that into a numerical inaquiltiy, that is 15<r but the answer to the question is B.
Hope this helps!
Brainliest would be nice!
Answer:
B
Step-by-step explanation:
Hello There!
An inequality must include < or > which means greater than or less than
This meaning that the inequality when shown by using words must include the is less than or more (sometimes greater) than
The answer would be B because it uses the expression is less than which can be represented by the inequality sign <
15 is less than r
exchange the inequality sign with is less than
15 < r
they still have the same meaning and it is written as an inequality
Reasons why its not the other answer choices
For A:
Four times 0.45 plus x
written as an expression:
4(0.45+x)
the expression does not include < or > therefore the statement "Four times 0.45 plus x " cannot be written as an inequality
For C:
Half the product of 4 and s
written as an expression:
[tex]\frac{4s}{2}[/tex]
once again the expression does not include an inequality sign therefore C is not the answer.
For D:
eight times p is 20
written as an expression
8p = 20
Like the other answer choices the expression does not include an inequality sign therefore D is not the correct answer choice
