Answer:
13 years the value of the car is 7700 dollars.
Step-by-step explanation:
Your search - { Present Volue = initial value (1-7.5%) t t is the years
∴7700 = 22300 (1-7,5%)^t
= $10.925 ) t = [tex]\frac{7700}{23300}[/tex] = 0.345 t=13
Supplement:
I year.
P value = 22300- 22300.7.5%
2 years
p value = (122300 - 22300. 7.5% ) - (22300-223107.5%)
= (22300 - 12300.7.5% ) (1-7.5%)
= 22300 (1-7.5%)(1-7.5%).
so t years :
p value = 22300 (1-7.5%)^t
the sum of two natural numbers is 28 the product if these numbers is three times the square of the smaller numbers, Find these numbers
Answer:
21 and 7
Step-by-step explanation:
I sort of just used trial and error, but i started with numbers that had a significant difference, like 20, and 8, or 22 and 6
The natural numbers are 7 and 21 if the sum of two natural numbers is 28 the product of these numbers is three times the square of the smaller numbers.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
The sum of two natural numbers is 28 the product of these numbers is three times the square of the smaller numbers
Let x and y be the numbers and x is the smaller number
x + y = 28
xy = 3x²
Plug y = 28 - x in the second equation:
x(28 - x) = 3x²
3x² -28x + x² = 0
4x² -28x = 0
4x(x - 7) = 0
x = 0 or x = 7
y = 28 or y = 21
The natural numbers are 7 and 21
Thus, the natural numbers are 7 and 21 if the sum of two natural numbers is 28 the product of these numbers is three times the square of the smaller numbers.

what will be the nature of roots of quadratic equation 2x²+4x-7=0?
Let us consider a quadratic equation αx² + βx + c = 0, then nature of roots of quadratic equation depends upon Discriminant (D) of the quadratic equation.
If Discriminant, D > 0, then roots of the equation are real and unequal.If Discriminant, D = 0, then roots of the equation are real and equal.If Discriminant, D < 0, then roots of the equation are unreal or complex or imaginary.Where,
[tex]\quad\red{ \underline { \boxed{ \sf{Discriminant, D = β² - 4αc}}}} [/tex]
Given Equation:-[tex]\red{\leadsto}\: \sf{2x^2 + 4x -7= 0} [/tex]
α = 2β = 4c = -7Now,
[tex]\quad\green{ \underline { \boxed{ \sf{Discriminant, D = β² - 4αc}}}} [/tex]
[tex]\begin{gathered}\begin{gathered}\implies\quad \sf D = 4^2-4\times 2\times ( - 7) \end{gathered} \end{gathered} [/tex]
[tex]\begin{gathered}\begin{gathered}\implies\quad \sf D = 16-( - 56)\end{gathered} \end{gathered} [/tex]

[tex]\begin{gathered}\begin{gathered}\implies\quad \sf D = 72 \end{gathered} \end{gathered} [/tex]
Since, Discriminant, D > 0, then roots of the equation are real and distinct.

If f(x) = x + 4 and g(x) = x3, what is (gºf)(-3)?
Answer:
(g ￮ f)(- 3) = 1
Step-by-step explanation:
evaluate f(- 3) then substitute the value obtained into g(x)
f(- 3) = - 3 + 4 = 1 , then
g(1) = 1³ = 1

Escribe la función que representa cada situación:
Utilizando los graficos, veremos que las dos funciones proporcionales son:
y = 3*xy = (3/2)*x¿Como escribir las funciones proporcionales?
Recordamos que una relación proporcional es de la forma:
y = k*x
Donde k es la constante de proporcionalidad.
Para el primer reto, simplemente debemos encontrar un par de valores (x, y) que pertenezca a la linea. Por ejemplo, podemos usar el par (1, 3).
Reemplazando eso en la relación proporcional, tenemos:
3 = k*1
3/1 = k = 3
Entonces la primera función es:
y = 3*x
Para el segundo reto hacemos lo mismo, primero debemos encontrar un par que pertenezca a la linea. Podemos usar el par (2, 3), reemplazando eso en la relación proporcional obtenemos:
3 = k*2
3/2 = k
Entonces la segunda función sera:
y = (3/2)*x.

Step-by-step explanation:
The equation of a line that passes through the point (-5,-1) and has a gradient of −1/2. Leave your answer in the form y=mx+c
The number of advance tickets sold was 52.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 8 is an equation.
We have,
Advance tickets x = $5.00
Tickets purchased the night of the concert cost y = $10.50
Total number of tickets = 78
The total cost of the tickets = $533
Now,
x + y = 78
x = 78 - y
Substituting
5x + 10.50y = 533
5 (78 - y) + 10.50y = 533
390 - 5y + 10.50y = 533
5.50y = 533 - 390
5.50y = 143
y = 26
Now,
x = 78 - y
x = 78 - 26
x = 52
Thus,
52 advance tickets were sold.

oh and how do we check the leaderboard
[tex]12s-4s+2=10 \\ 8s = 10 - 2 \\ 8s = 8 \\ \cancel8 s = \cancel8 \\ s = 1[/tex]
Solution:
We know that:
Given equation: 12s - 4s + 2 = 10Step-1: Combine like terms
12s - 4s + 2 = 10s(12 - 4) + 2 = 10s(8) + 2 = 10Step-2: Subtract 2 both sides
s(8) + 2 - 2 = 10 - 2s(8) = 8Step-3: Divide 3 both sides
s(8)/8 = 8/8s = 8/8 = 1Thus, the value of s is 1.

Solution:
In the table, we can see that as each round pass, the number of games is being halved.
This means that:
⇒ Round 4 = (Round 3)/2 = 16/2 = 8 games⇒ Round 5 = (Round 4)/2 = 8/2 = 4 games⇒ Round 6 = (Round 5)/2 = 4/2 = 2 gamesHence, in round six, two games will be played.
