The probability that two batteries used sequentially will remaining greater than 4 years is about 6.95%.
The time to failure of a single rechargeable battery is exponentially distributed with a median of three years. which means that the opportunity that a single battery will ultimate more than 4 years is given via:
P(X > 4) = e^(-4/3) ≈ 0.2636
Wherein X is the time to failure of a single battery.
Assuming that the two batteries are used sequentially and independently, the chance that each batteries will remaining more than four years is given by means of the made from their man or woman probabilities:
P(X1 > 4 and X2 > 4) = P(X1 > 4) * P(X2 > 4)
For the reason that two batteries are used successionally, the probability of the alternate battery lasting further than 4 times is analogous to the chance of the first battery lasting redundant than 4 years
P(X1 > 4 and X2 > 4) = P(X > 4)^2 ≈ 0.0695
Consequently, the probability that two batteries used sequentially will remaining greater than 4 years is about 0.0695 or 6.95%.

Write a rule for describing the total rate r as a function of the total miles m.
What is the taxi rate for 12 miles?
Answer:
r = 5.1666...
Step-by-step explanation:
4.25 + 1.5r = m
4.25 + 1.5r = 12
1.5r = 12 - 4.25
1.5r = 7.75

the shop advertises a sale. customers can rent one bicycle at the regular hourly rate and rent a
second bicycle at 1.2 the regular hourly rate.
what is the total cost to rent two bicycles for 4 hours by using this pricing? explain how you know.
The total cost to rent two bicycles for 4 hours using this pricing is $44.80.
To determine this, we can first calculate the cost of the first bicycle at the regular hourly rate:
Cost of first bicycle = regular hourly rate * number of hours = $10 * 4 = $40
We can then calculate the cost of the second bicycle at 1.2 times the regular hourly rate:
Cost of second bicycle = (regular hourly rate * 1.2) * number of hours = ($10 * 1.2) * 4 = $48
The total cost to rent both bicycles is the sum of the costs of the individual bicycles:
Total cost = cost of first bicycle + cost of second bicycle = $40 + $48 = $88
However, the shop is advertising a sale, so we need to divide the total cost by 2 to get the final cost:
Final cost = total cost/2 = $88/2 = $44
Rounded to the nearest cent, the final cost is $44.80. This is the total cost to rent two bicycles for 4 hours using the pricing advertised in the sale.

rewrite the following radical expression in rational exponent form.
(underroot x)5
The given radical expression is (√x)^5. To rewrite it in rational exponent form, we need to express the square root (√) as a fractional exponent.
The square root (√) of x can be written as x^(1/2).
To raise x^(1/2) to the power of 5, we can multiply the exponents: (x^(1/2))^5 = x^(5/2).
Therefore, the radical expression (√x)^5 can be rewritten as x^(5/2) in rational exponent form.
In summary, (√x)^5 is equivalent to x^(5/2) in rational exponent form.

Jenny has only 3 1/2 cups of flour in her house. She needs 1 5/8 cups for a brownie recipe. Her sister Jody needs 1 3/4 cup flour for her cookie recipe. Will there be enough flour for both recipes?
Answer:
Yes, with 1/8 cup left over
Step-by-step explanation:
First, we are going to convert the fractions to a common denominator. You can see all the numbers are a factor of 8, so 8 will be our common denominator.
Converting 3 1/2: Let's ignore the 3 and only pay attention to the fraction.
1/2 * 4/4 = 4/8, so our new fraction is 3 4/8
Converting 1 3/4: We ignore the whole number (1) and pay attention to 3/4.
3/4 * 2/2 = 6/8, so our new fraction is 1 6/8
Now that we have the correct fractions to make it easy to subtract, we make our equation:
1 5/8 + 1 6/8 = 2 11/8, simplified: 3 3/8
We know that in total, Jenny has 3 4/8 cups and she used 3 3/8 cups in total, so yes, there will be enough with 1/8 cup left over.

After t seconds a ball tossed In the air from the ground level reaches a height and of h feet given by the function h(t)=144t-16t^2
1) When will the ball reach the maximum height?
Answer:
Check the explantion
Step-by-step explanation:
H(t) represent the height of the ball after t seconds.
1)
In order to figure the maximum height of the ball we must minupulate this equation into a form where we can easily find the maximum height.
We can also see this parabola will be downward concaved because it has a negative coefficent for the t^2 term.
a) Let's Manipulate!
Vertex form is a form where we can easily tell the maximum and minimum points. To get in into Vertex form we just need to complete the sqaure.
Lets reanrage the terms
h(t)= -16t^2+144t
Undo the distrubitive propety
h(t)= -16(t^2-9t+20.25)+324
Add and subtract 324.
h(t) = -16(t-4.5)^2+324
COmplete the square.
b) Almost done!
We can now see that the stuff with the brackets is always positive/zero because any real number sqaured is a positive/zero. But than we multiply the positive stuff by a negative number (-16) so its now all negative.
The only exception is when its zero.
And off course if we add 324 to zero its always going to be greater than 324 + a negative number. To get the first term to be zero we can have t = 4.5.
c) Proove it!
h(4.5) = -16(4.5-4.5)^2+324
=324
d) Double Check by graphing!
(Its a attach screenshote by the way)
e) Answer:
The ball will reach its maximum height after 4.5 seconds.

Answer:
18.87 square cm.
Step-by-step explanation:
The area of the rectangle will be (4 + 4) * 4, since the length of the rectangle would be the diameter of the circle, and the width of the rectangle would be the radius. (4 + 4) * 4 = 8 * 4 = 32 square cm.
Then, we can calculate the area of the semicircle. The area of a circle is pi * r^2, so the area of a semicircle will be half of that. pi * (4^2) / 2 = pi * 16 / 2 = 8pi. 8 * 3.14159265 = 25.1327412 square cm.
The shaded area of the middle of the shape will then be 32 - 25.1327412 = 6.8672588 square cm.
The two triangles will have the same area. Their bases will be 14 minus the diameter of the circle, then divide that by 2 to get each separate base. 14 - 8 = 6 / 2 = 3. The heights of the triangles will be the radius of the circle, or 4 cm.
1/2 * 3 * 4 = 1/2 * 12 = 12/2 = 6. That is the area of one triangle, so the area of both triangles would be 6 * 2 = 12 square cm.
6.8672588 + 12 = 18.8672588, or 18.87 square cm.
Hope this helps!
Answer:
(44 - 8(pi)) cm^2 Exact area
18,9 cm^2 Approximate area
Step-by-step explanation:
The shaded area is the area of the trapezoid minus the area of the semicircle.
area of trapezoid = (b1 + b2)h/2
area of semicircle = (pi)(r^2)/2
The triangles at both sides are right triangles. Each of the horizontal legs has length (14 cm - 8 cm)/2 = 3 cm. Each of the vertical legs is congruent to the radius of the semicircle.
b1 = lower base = 14 cm
b2 = upper base = 14 cm - 3 cm - 3 cm = 8 cm
shaded area = (b1 + b2)h/2 - (pi)(r^2)/2
= (14 cm + 8 cm)(4 cm)/2 - (pi)(4 cm)^2 / 2
= 44 cm^2 - 8(pi) cm^2
= (44 - 8(pi)) cm^2 Exact area
= 18.9 cm^2 Approximate area

Step-by-step explanation:
The formula for future value is ...
FV = P(1 +r/n)^(nt)
for principal P at annual interest rate r compounded n times per year for t years.
This formula is built in to most spreadsheet programs, which can be usefully used to calculate its value for different values of the variables. The spreadsheet function needs the interest rate per period (r/n) and the number of periods (nt).
Continuous compounding can be reasonably approximated by compounding 100 million times per year. Or the continuous compounding formula can be used:
FV = Pe^(rt)
The attached spreadsheet shows the values for these problems, and it shows the formula used to obtain them.
_____
Additional comment
Spreadsheet functions often work in terms of cash flow. A payment has one sign, and a value received has the opposite sign. Here, we have shown -FV( ) in the spreadsheet, because the given arguments would otherwise show the FV as negative. (More properly, the last function input would be the opposite of the principal value, as it is a payment being made.)
chipotle mexican grill inc. issues a 6 percent coupon bond with 19 years maturity and $1,000 face (par) value. if the current market price of this bond is $986, find its yield to maturity.
To find the yield to maturity (YTM) of the bond, we need to solve for the interest rate that equates the present value of the bond's cash flows to its current market price.
The cash flows of the bond consist of the periodic coupon payments and the final principal repayment. In this case, the bond has a 6% coupon rate and a 19-year maturity with a $1,000 face value.
The YTM can be calculated using financial functions or by using an iterative approach. Here, I will demonstrate the iterative approach using the Newton-Raphson method to solve for YTM:
Step 1: Set the parameters and initial guess
Face value (F) = $1,000
Coupon rate (C) = 6% = 0.06
Maturity (N) = 19 years
Market price (P) = $986
Initial guess for YTM (r) = 0.06 (6%)
Step 2: Set up the equation to solve
The present value of the bond's cash flows can be calculated as follows:
P = C * (1 - \((1 + r)^{(-N)}\)) / r + F / \((1 + r)^N\)
Step 3: Iterate to find the YTM
Use the Newton-Raphson method to iteratively solve for YTM until the equation is satisfied.
Repeat the following steps until convergence is achieved:
Calculate the present value of the bond's cash flows using the current YTM guess.
Calculate the derivative of the equation with respect to YTM.
Update the YTM guess using the formula:\(r_new = r - (P - calculated_present_value) / derivative\)
Continue iterating until the difference between the current and previous YTM guesses is negligible (i.e., convergence is achieved).
After performing the calculations, the yield to maturity (YTM) of the bond is approximately 6.11%.

dos numeros estan en la misma proporcion que los numeros 2 y 5. si se aumenta 75 a uno de ellos y 15 al otro. se obtendrian cantidades iguales. ¿cual es el menor?
The proportion based on the Smallest number is 40.
The smallest number, let's set up the proportion based on the given information. Let's assume the two numbers are represented by x and y.
The given proportion is:
x/y = 2/5
According to the problem, if we add 75 to one number and 15 to the other, the resulting amounts would be equal. This can be expressed as:
(x + 75) = (y + 15)
To find the smallest number, we can solve this system of equations. We can rearrange the second equation to isolate y:
y = (x + 75) - 15
y = x + 60
Now we can substitute this expression for y in the first equation:
x/(x + 60) = 2/5
To solve for x, we can cross-multiply:
5x = 2(x + 60)
5x = 2x + 120
3x = 120
x = 40
Now that we have the value of x, we can substitute it back into the second equation to find y:
y = x + 60
y = 40 + 60
y = 100
Therefore, the smallest number is 40.
