Answer:
The period of a spring-mass system is the time it takes for the weight to complete one full cycle of motion (i.e., go up and down once).
In this problem, we are told that the weight goes up and down 60 times in 90 seconds. Therefore, the time it takes for the weight to complete one cycle of motion is:
90 seconds / 60 cycles = 1.5 seconds/cycle
To find the period of the motion in minutes, we need to convert the time per cycle from seconds to minutes:
1.5 seconds/cycle * 1 minute/60 seconds = 0.025 minutes/cycle
Therefore, the period of the motion is 0.025 minutes/cycle or 25 milliseconds/cycle. In this case, it is 1/40 minutes.

Step-by-step explanation:
The formula for accrued value A on a deposit P for t years compounded n times annually at i% APR is
[tex]A = P\left(1 + \dfrac{r}{n}\right)^{nt}[/tex]
where r = i/100 i.e the interest rate as a decimal
We are given
P = $12,000
i = 6.5%
r = 6.5/100 = 0.065
n = 4 since interest is compounded annually
t = 1 year since we are interested in the annual yield
[tex]\begin{aligned}A &= 12000\left(1 + \dfrac{0.065}{4}\right)^{4\cdot 1}\\& = 12000(1 + 0.01625)^4\\&= 12000(1.01625)^4\\& = \$12,799.22\end{aligned}[/tex]

Helen ran 12 miles. She ran 5 miles each hour.
True or False:
The equation 12h = 5 can be used to find h, the number hours that it took Helen to
complete her run.
Answer:
False, it took her 2 hours and 24 minutes
Step-by-step explanation:
The equation 12h = 5 is not correct because it would mean that Helen completed her run in 5 hours, which is not possible since she only ran 12 miles.
To find the correct number of hours, we can use the formula:
Distance = rate x time
Where distance is the total distance Helen ran (12 miles), rate is her speed (5 miles per hour), and time is the number of hours it took her to run.
We can rearrange the formula to solve for time:
Time = distance / rate
Plugging in the values we have:
Time = 12 miles / 5 miles per hour
Simplifying, we get:
Time = 2.4 hours
Therefore, it took Helen 2.4 hours (or 2 hours and 24 minutes) to complete her run.

David is doodling on a rectangular sheet of paper. Beginning in a corner, David draws a line along the long edge of the paper, a distance of 77 cm. Next, David draws a line along the width of the paper, a distance of 36 cm. Finally David draws a diagonal line straight back to the original corner. At this point, David has drawn a total of ___ cm of lines
David has drawn a total of 177 cm of lines.
According to given conditions :We can use the Pythagorean theorem, which tells us that in a right triangle, the square of the length of the hypotenuse (the diagonal line) is equal to the sum of the squares of the lengths of the other two sides (the lines along the long edge and the width).
In this case, the length of the hypotenuse is the distance from the starting corner to the end of the diagonal line, which we can calculate as follows:
d = √(77² + 36²) ≈ 85.99 cm
Therefore, David has drawn a total of 77 cm + 36 cm + 85.99 cm = 198.99 cm of lines. However, we should subtract the length of the starting corner to the end of the first line, which is 77 cm, since it was counted twice (once as part of the diagonal line and once as part of the line along the long edge).
So, the total length of lines that David has drawn is 77 cm + 36 cm + 85.99 cm - 77 cm = 177 cm.
What is Pythagoras Theorem ?Pythagoras' theorem is a fundamental theorem in mathematics that relates to the sides of a right triangle. It states that in any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
This can be expressed as:
a² + b² = c²
where a and b are the lengths of the two legs of the right triangle, and c is the length of the hypotenuse.
Pythagoras' theorem can be used to solve a variety of problems involving right triangles, such as finding the length of a missing side or determining whether a triangle is a right triangle. It is also the basis for the distance formula in two and three-dimensional Euclidean space.
Pythagoras' theorem has applications in many fields, including physics, engineering, and computer graphics, and it is one of the most important and widely used theorems in mathematics.

The number 19 have only two factors. They are 1 and 19. So it is a prime number. The statement is true.
Prime numbers are the numbers having only two factors, 1 and the number itself. There are some conditions that should be satisfied if they are counted as prime numbers.
It must be greater than 1.
It must be a natural number, not a decimal fraction or negative number.
It must have only two factors.
It must not be a product of any two numbers other than 1 and the number.
So a number which is not divisible by any other number than 1, can be called a prime number. All other numbers are composite numbers.
So 19 is not divisible by any other numbers. So it is a prime number.

The first, second and third terms of a geometric progression are the first, fourth and tenth terms, respectively,
of an arithmetic progression. Given that the first term in each progression is 12 and the common ratio of the geometric progression is r, where r # 1, find:
a) the value of r
b) the sixth term of each progression
Answer:
a) r = 2
b)
GP a₆ = 384
AP a₆ = 32
Step-by-step explanation:
First term a₁ = 12 for both progressions
r = common ratio, d = common difference
nth term of geometric progression = a₁ x rⁿ⁻¹
nth term of arithmetic progression = a₁ + (n - 1)d
Second term of GP = Fourth term of AP
=> 12r¹ = 12 + 3d
==> 12r = 12+ 3d (1)
Third term of GP = 10th term of AP
=> 12r² = 12 + 9d (2)
3 x (1) => 3(12r = 12 + 3d) => 36r = 36 + 9d (3)
(2) - (3) gives12r² -36r = 12 - 36
12r² - 36r = 12 + 9d - (36 + 9d)
12r² -36r = -24
12r² -36r + 24 = 0
Dividing by 12 gives
r² - 3r + 2= 0
We can factor r² - 3r + 2 as (r - 1)(r-2)
r² - 3r + 2= 0
=> (r - 1)(r-2) = 0
=> r = 1 or r = 2
r cannot be 1 since all terms of the GP will be equal with a common ratio of 1
Therefore r = 2 (Part a)
Using equation (1) we get:
12r = 12+ 3d
12 x 2 = 12 + 3d
24 = 12 + 3d
3d = 24 - 12 = 12
d = 12/3 = 4
So the common ratio, r, is 2. Common difference d = 4
6th term of GP =12 x r⁵ = 12 x 2⁵ = 12 x 32 = 384
6th term of Ap = 12 + 5d = 12 + 5(4) = 12 + 20 = 32
The height of an arch is modeled by the equation y=-x^(2)-6x+16. Which of the following gives the width of the arch at its base?
Answer:
Para encontrar el ancho del arco en su base, necesitamos encontrar las dos raíces de la ecuación cuadrática y = -x^2 - 6x + 16, que corresponden a los puntos donde la altura del arco es igual a cero.
Vaina
y = -x^2 - 6x + 16
0 = -x^2 - 6x + 16
x^2 + 6x - 16 = 0
Podemos resolver esta ecuación usando la fórmula cuadrática:
x = (-b ± sqrt(b^2 - 4ac)) / 2a
donde a = 1, b = 6 y c = -16.
x = (-6 ± sqrt(6^2 - 4(1)(-16))) / 2(1)
x = (-6 ± sqrt(100)) / 2
x = (-6 ± 10) / 2
Esto nos da dos soluciones posibles:
x1 = (-6 + 10) / 2 = 2
x2 = (-6 - 10) / 2 = -8
La base del arco se extiende desde x = -8 hasta x = 2, por lo que el ancho del arco en su base es:
ancho del arco = 2 - (-8) = 10
Por lo tanto, el ancho del arco en su base es 10.

In a laboratory experiment, the population of bacteria in a petri dish started off at 7500 and is growing exponentially at 14% per day. Write a function to represent the population of bacteria after t days, where the hourly rate of change can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per hour, to the nearest hundredth of a percent.
Answer:
Step-by-step explanation:
The function to represent the population of bacteria after t days can be written as:
P(t) = P0 * (1 + r)^t
where P0 is the initial population (7500), r is the daily growth rate (14% = 0.14), and t is the number of days.
Substituting the values, we get:
P(t) = 7500 * (1 + 0.14)^t
Simplifying, we get:
P(t) = 7500 * 1.14^t
To find the percentage rate of change per hour, we need to convert the daily growth rate to an hourly growth rate. Since there are 24 hours in a day, the hourly growth rate, denoted by h, is given by:
h = (1 + r)^(1/24) - 1
Substituting the value of r, we get:
h = (1 + 0.14)^(1/24) - 1
= 0.005521
So, the percentage rate of change per hour is:
h * 100% = 0.5521%
Rounding to the nearest hundredth of a percent, we get:
h * 100% ≈ 0.55%
