the cost of a can of coca-cola in 1960 was $ 0.10 . the function that models the cost of a coca-cola by year is c ( t )
The cost of the Coca-Cola can will be $1 in the year 2000.
Given that the cost of a can of Coca-Cola can in 1960 = $0.10
The function which models the cost of a Coca-Cola by year 't' is
c(t) = [tex]0.10e^{0.0576t}[/tex].
Here, 't' denotes the number of years since 1960.
c(t) is an exponential function.
We have to find the year in which the cost of a can will be $1.
So substitute c(t) = 1, we get,
1 = [tex]0.10e^{0.0576t}[/tex]
⇒ [tex]10 = e^{0.0576t}[/tex]
We have, [tex]ln(e^x) = x[/tex] .
Taking logarithm on both sides, we get,
log(10) = 0.0576t
⇒ [tex]t=\frac{ln(10)}{0.0576}[/tex] = 39.97 ≈ 40 years .
Thus the cost of a can of Coca-Cola will be $1 in the year, 1960 + 40 = 2000.
The question was incomplete. Find the complete question at:
The cost of a can of Coca-Cola in 1960 , was $0.10. The function that models the cost of a Coca-Cola by year is C(t)=0.10e^(0.0576t) , where t is the number of years since 1960 . In what year is it expected that a can of Coca-Cola will cost $1.00 ?

money marilyn is going on a class outing to an amusement park. she has $40 to spend. the admission price is $20. she plans to buy a sandwich for $5. a cup of lemonade costs $3.00. write an inequality to show how many cups of lemonade, c, she can buy.
Money Marilyn can buy 1≤ x≤5 (more than or equal to one and less than or equal to five) cups of lemonade from the rest of the money.
Here we have,
Total money to spend= $40
Admission price= $20
Sandwich= $5
Add all expenses to find the money spent by Money Marilyn.
Total expense= admission price + sandwich
Total expense = $20 + $5 = $25
Amount left with her= $40-$25 = $15
The number of cups when each cup's cost is $3
Total lemonade(x) = $15/$3 = $5
In an equality,
Money Marilyn can buy 1≤ x≤5 (more than or equal to one and less than or equal to five) lemonades from the rest of the money.

Step-by-step explanation:
Very hard as problem.
1. we suppose 2 variables a and b.
we find that b=5a/6
2. One more variable c
we find c=13a/24
3. a must be a multiple of 24 and perimeter is 44*a/6 = 176a/24
Write the equation in standard form given the following information (with solutions please)
1. The roots are 1/2 and -1/2
The Quadratic equation in standard form given the following roots are
f(x) = 2x^2 - 3x + 1
The root 1 is associated with the factor (x - 1).
The root 1/2 is associated with the factor (x - 1/2), which in turn is equivalent to (2x -1)
The quadratic in question is f(x) = (x - 1)(2x - 1). To write this in standard form, perform the indicated multiplication:
f(x) = 2x^2 - 2x - x + 1, or f(x) = 2x^2 - 3x + 1
What is Quadratic equation?Any equation in algebra that can be written in standard form as where x is an unknown and a, b, and c denote known numbers, where a 0 is a quadratic equation.
An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as a[tex]x^{2}[/tex] + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.

Answer: 164.53%
Step-by-step explanation:
105.3/64=1.6453125
1.6453125*100=164.53125
164.53125=164.53%
Notice the answer is greater than 100 percent. This is because 105.3 is greater than 64, meaning that 105.3 is greater than 100% of 64, so 105.3 will have a greater percent value.

At the beginning of the day, the stock market goes down 70 1/2 points and stays at this level for most of the day. At the end of the day the stock market goes up 80 3/4 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
The change for the day is 10 1/4
In this problem, we are expected to calculate the change in the price of a particular stock
Given that the days high is 80 3/4
and also that the days low is 70 1/2
we can calculate the change by subtracting the days low from the days high
i.e 80 3/4- 70 1/2= 323/4-141/2= (323-282)/4= 41/4
hence the change for the day is 41/4 =10 1/4
Also we can calculate the percentage change as
%change = (high-low)/low*100
%change= 80 3/4- 70 1/2/70 1/2*100= 41/4/70 1/2 *100
%change= 41/4*2/141*100
%change= 0.00145=0.145%

arc xylocated on circle ahas a length of 40 centimeters. the radius of the circle is 10 centimeters. what is the measure of the corresponding central angle for xy⌢in radians?
We know that an arc is a part of the entire perimeter of a circle.
Radian is defined as a unit of plane angular measurement that is equal to the angle subtended by the circle at the center by an arc that is of the length equal to the radius
We also know that the circle as a whole contains 2π radians
Now first we are required to find the perimeter of the circle
Perimeter of the circle is given by the formula 2πr
Hence, perimeter of the circle = 2πr= 2π x 10 =20π=62.851cm
Hence value of arc in radians = 40/62.851 x 2π =0.636 x 2 π =1.272π
Radian can be converted to degree by multiplying the radian measure by 180/π
Therefore, angle subtended by arc in degrees =1.272 π x 180 /π =229.1 °
Hence the angle subtended by arc is 229.1°

if the least common multiple of $a$ and $b$ is $1575$, and the ratio of $a$ to $b$ is $3:7$, then what is their greatest common divisor?
The greatest common divisor of two given numbers is 15.
Given that, the least common multiple of A and B is 1575 and A: B=3: 7.
We need to find what is their greatest common divisor.
What is the least common multiple?The least common multiple is also known as LCM (or) the lowest common multiple in math. The least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.
We know that the product of the GCF and the LCM of two numbers is always the product of the two numbers.
Let the GCF of two numbers be x.
Then A×B=1575×x
Take A:B=3k:7k
Now, 3k×7k=1575×x
⇒21k²=1575x
⇒k²=75x
x must be expressed as a square divided by 75.
Now, 75=3×5×5
If we multiply 3 to the above product we get the perfect square number.
So, k²=225
⇒k=15
Now, 3k=45 and 7k=105
45=3×3×5 and 105=3×5×7
So, GCD=3×5=15
Therefore, the greatest common divisor of two given numbers is 15.

Your question is incomplete, probably the complete question/missing part is:
If the least common multiple of A and B is 1575, and the ratio A of B to 3 is 7 , then what is their greatest common divisor?
Answer: 75
Step-by-step explanation:
Since the ratio of A to B is 3:7:
There is an integer k for which A=3k and B=7k.
Moveover, k is the greatest common divisor of A and B, since 3 and 7 are relatively prime.
Recalling the identity lcm(A,B)*gcd(A,B)=AB, we find that 1575k=(3k)(7k), which implies k=1575/21=75.
