$650 is invested in an account earning 8.6% interest (APR), compounded monthly. Write a function showing the value of the account after tt years, where the annual growth rate can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage of growth per year (APY), to the nearest hundredth of a percent.
Answers
Answer:
The value of the acount after t years is of [tex]A(t) = 650(1.0072)^{12t}[/tex]
The annual growth rate is of 0.72%.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
$650 is invested in an account earning 8.6% interest (APR), compounded monthly.
This means that [tex]P = 650, r = 0.086, n = 12[/tex]. So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(t) = 650(1 + \frac{0.086}{12})^{12t}[/tex]
[tex]A(t) = 650(1.0072)^{12t}[/tex]
The value of the acount after t years is of [tex]A(t) = 650(1.0072)^{12t}[/tex]
Annual growth rate
1.0072 - 1 = 0.0072 = 0.72%
The annual growth rate is of 0.72%.

Find an equation of a line of best fit shown in the figure given below.
Answers
Answer:
C
Step-by-step explanation:
So you can use two points on the line to find the gradient. I used K and G. B and D could've been easily eliminated since the line goes through the origin (0,0) so there's no y - intercept or b value.
M = (Y-y)/(X-x)
M = (8-4)/(14-7)
M = 4/7
And the equation of a line is y = mx + b. There's no b so it's just y = (4/7)x

Si la altura del triángulo es 4 cm cuántos centímetros cuadrados mediría el área del triángulo al ampliarlo usando el factor de escala de 4
Answers
Answer:
Para un triángulo de base B y altura H, el área se calcula como:
A = B*H/2
En este caso, tenemos un triángulo con altura igual a 4cm, entonces el área será:
A = (4cm)*B/2 = B*2cm
(Como no conocemos la base, no podemos obtener una respuesta exacta)
Si ampliamos el triángulo usando un factor de escala 4, entonces todas las medidas del triángulo son 4 veces más grandes, entonces la nueva altura es:
H' = 4*H = 4*4cm = 16cm
La nueva base será:
B' = 4*B
Entonces la nueva área es:
A' = (16cm)*4B/2 = (8cm)*(4B) = (4*2cm)*(4B) = (4*4)*(2cm*B) = 16*(2cm*B)
Y 2cm*B era el área original del triángulo, entonces:
A' = 16*A
Esto nos dice que la nueva área será 16 veces el área original.

d. calculate the P(X31) using the binomial formula or a cumulative table in excel e)
e. both b and care correct f)
f. both c and d are correct
Answers
Answer:
calculate P(X=1) + P(X=2) +...+ P(X=12) using the binomial formula or an individual table in excel
calculate the P(X ≥ 12) using the binomial formula or a cumulative table in excel
Step-by-step explanation:
For a binomial distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
n = number of trials = 12 ; x = number of successes
p = probability of success = 0.2% = 0.002
1 - p = 1 - 0.002 = 0.998
Probability that atleast 1 is broken ;
p(1) + p(2) + p(3) +... + p(12) ;
This can be calculated by summing the values obtained using the binomial formula or in excel.
Alternatively, using the binomial formular or excel, the cumulative probability could be obtained as P(x ≥ 1)

In a lab experiment, 80 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 16 hours. Write a function showing the number of bacteria after tt hours, where the hourly growth rate can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage of growth per hour, to the nearest hundredth of a percent.
Answers
Answer:
The hourly growth rate is of 4.43%.
The function showing the number of bacteria after t hours is [tex]P(t) = 80(1.0443)^t[/tex]
Step-by-step explanation:
Equation of population growth:
The equation for the population after t hours is given by:
[tex]P(t) = P(0)(1+r)^t[/tex]
In which P(0) is the initial population and r is the growth rate, as a decimal.
The conditions are such that the number of bacteria is able to double every 16 hours.
This means that [tex]P(16) = 2P(0)[/tex]. We use this to find r.
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]2P(0) = P(0)(1+r)^{16}[/tex]
[tex](1+r)^{16} = 2[/tex]
[tex]\sqrt[16]{(1+r)^{16}} = \sqrt[16]{2}[/tex]
[tex]1 + r = 2^{\frac{1}{16}}[/tex]
[tex]1 + r = 1.0443[/tex]
[tex]r = 1.0443 - 1[/tex]
[tex]r = 0.0443[/tex]
The hourly growth rate is of 4.43%.
80 bacteria are placed in a petri dish.
This means that [tex]P(0) = 80[/tex].
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]P(t) = 80(1+0.0443)^t[/tex]
[tex]P(t) = 80(1.0443)^t[/tex]
The function showing the number of bacteria after t hours is [tex]P(t) = 80(1.0443)^t[/tex]

Garth can row 5 miles per hour in still water. It takes him as long to row 4 miles upstream as 16 miles
downstream. How fast is the current?
Answers
Answer:
The speed of the current is 3 miles per hour
Step-by-step explanation:
The equations for rate (r), distance (d), and time (t) are ⇒ d = rt, r = d/t, = t = d/r
Let x = speed in still water
Let c = speed of the current
The main difference with these problems is rate needs to be expressed using two variables because moving upstream the current is against you and downstream it moves with you.
Distance Rate Time
Upstream x − c
Downstream x + c
The distance column with the numbers from the problem and the value for speed in still water for x.
Distance Rate Time
Upstream 4 5 − c
Downstream 16 5 + c
The column for time using the other two columns knowing that rate, distance ⇒ time = Distance Rate Time
Upstream 4 5 − c
5 − c
4
Downstream 16 5 + c
5 + c
16
“It takes as long …” from the problem means that the two times are equal to each other. So, the equation can be written as:
4/5− c = 16/5 + c ⇒ Solve by cross-multiplying ⇒ 5(4 + c) = 16 5( − c) ⇒ c = 3
