The dollar value of a car is a function, f, of the number of years, t, since the car was purchased. The function is defined by the equation f(t)=12,000(3/4)^t.
A. How much was the car worth when it was purchased? Explain how you know.
B. What is f(2)? What does this tell you about the car?
C. About when was the car worth $6,000? Explain how you know.
Answer:
1.) 12000
2.) 6750
3.) 2.41
Step-by-step explanation:
Given the Equation :
f(t)=12,000(3/4)^t. ; where, t = time ; f(t) = worth of car at time, t
When, car was purchased, t = 0
t = 0
f(0) = 12000(3/4)^0
= 12000 * 1
= 12000
2.)
f(2) ; this mean the worth of the car after 2 years :
f(2)=12,000(3/4)^t.
12000(3/4)^2
12000 * 0.5625
= 6750
When car will be worth 6000
f(t) = 6000
f(t)=12,000(3/4)^t.
6000 = 12,000(3/4)^t
6000 / 12000 = (3/4)^t
1/2 = (3/4)^t
Take the log of both sides :
Log(0.5) = log(0.75)^t
log(0.5) = tlog(0.75)
- 0.301029 = - 0.124938t
t = - 0.301029 / - 0.124938
t = 2.4094
t = 2.41 years

Find the y-intercept of the parabola y = x2 + 6x.
Can somebody help?
Given:
The equation of the parabola is:
[tex]y=x^2+6x[/tex]
To find:
The y-intercept of the parabola.
Solution:
We have,
[tex]y=x^2+6x[/tex]
Putting [tex]x=0[/tex] in the given equation, we get
[tex]y=(0)^2+6(0)[/tex]
[tex]y=0+0[/tex]
[tex]y=0[/tex]
Therefore, the y-intercept of the parabola is 0. It means the y-intercept of the given parabola is at point (0,0).

Owen and Jesse go to a restaurant for breakfast. A 7% sales tax is applied to their $21.60 bill. If Owen and Jesse add a 15% tip after the tax is applied, what is the total cost, including tip?
Answer:
The total cost is 26.6 dollars
Step-by-step explanation:
Given
The total bill of the breakfast = $ 21.60
Sales tax = 7% of the total bill value
Total bill after adding the 7% sales tax
$ 21.60 + 7% of $ 21.60
[tex]21.60 + \frac{7}{100} * 21.60\\21.60 + 1.512\\23.112[/tex]dollars
After adding 15% of the tip values to the payable amount of $ 23.112, the total bill becomes
$ 23.112 + 15% of $ 23.112
[tex]23.112 + 3.4668 = 26.5788[/tex]
The total cost is 26.6 dollars
The approximate molar concentration of several chemicals are given. Find the pH of each use the calculator and round to the nearest 10th if necessary. Here is the photo of the question
Answer:
[tex]pH = 13[/tex] --- Oven Cleaner
[tex]pH = 6.2[/tex] --- Water
[tex]pH =7.4[/tex] --- Blood
[tex]pH = 2.2[/tex] --- Vinegar
Step-by-step explanation:
The given molar concentration are:[Missing from the question]
Oven Cleaner: [h+] = [tex]10^{-13}[/tex]
Water: [h+] = [tex]0.0000007[/tex]
Blood: [h+] = [tex]0.00000004[/tex]
Vinegar: [h+] = [tex]0.0063[/tex]
Required
Determine the pH
pH is calculated using:
[tex]pH = -\log(h+)[/tex]
So, we have:
Oven Cleaner:
[tex]pH = -\log(10^{-13})[/tex]
Using a calculator, we have:
[tex]pH = 13[/tex]
Water:
[tex]pH = -\log(0.0000007)[/tex]
Using a calculator, we have:
[tex]pH = -1*-6.2[/tex]
[tex]pH = 6.2[/tex]
Blood:
[tex]pH = -\log(0.00000004)[/tex]
Using a calculator, we have:
[tex]pH = -1 * -7.4[/tex]
[tex]pH =7.4[/tex]
Vinegar:
[tex]pH = -\log(0.0063 )[/tex]
Using a calculator, we have:
[tex]pH = -1 * -2.2[/tex]
[tex]pH = 2.2[/tex]

Si se lanzan 2 dados ¿ cuantas posibilidades hay de que las caras hacia arriba sumen un numero menor que 7?
Answer:
P = 15/36 = 0.4166...
Step-by-step explanation:
Cada dado tiene 6 caras, con los números entre 1 y 6.
Entonces tenemos dos eventos, con 6 posibles resultados cada uno.
El número total de resultados para el evento de lanzar los dos dados, es el producto de los números de resultados para cada dado, entonces tenemos:
C = 6*6 = 36 posibles resultados.
Ahora tenemos que contar el número de resultados en donde la suma es menor a 7.
Usando la notación:
(resultado del dado 1) y (resultado del dado 2) = suma
Esos son:
1 y 1 = 2
1 y 2 = 3
1 y 3 = 4
1 y 4 = 5
1 y 5 = 6
2 y 1 = 3
2 y 2 = 4
2 y 3 = 5
2 y 4 = 6
3 y 1 = 4
3 y 2 = 5
3 y 3 = 6
4 y 1 = 5
4 y 2 = 6
5 y 1 = 6
Hay 15 resultados donde la suma de los resultados individuales es menor a 7.
Entonces de un total de 36 posibles resultados, 15 cumplen lo que queremos, asi que la probabilidad de que las caras hacía arriba sumen un número menor que 7 son de 15 entre 36, o:
P = 15/36 = 0.4166...

What is the distance between the points (5, -1) and (5,
3)
By using distance formula (which is attached below), you can solve this problem:
√(x2-x1)^2+(y2-y1)^2
(5, -1) and (5, 3)
√(5-5)^2+(3-(-1))^2
√0^2+4^2
√0+16
√16
4
The distance between the two points is 4.
