The end of the long hand of the clock travels about 78.54 inches (25π) in 2 1/2 hours.
What is clock ?
Clock can be defined as a machine in which a device that performs regular movements in equal intervals of time is linked to a counting mechanism that records the number of movements
The long hand of the clock completes one full revolution in 12 hours. Therefore, in one hour, it travels a distance equal to the circumference of a circle with a radius of 5 inches, which is given by 2πr = 2π(5) = 10π inches.
In 2 1/2 hours, the long hand of the clock travels a distance equal to (2 1/2) x 10π = 25π inches.
So, the end of the long hand of the clock travels about 78.54 inches (25π) in 2 1/2 hours.

This question is incomplete
Complete Question
A baker uses 5.5 Ibs of flour daily
The baker's recipe for a loaf of bread calls for 12 oz of flour. If he uses all of his flour to make loaves of bread, how many loaves can he bake in seven days?
Answer:
51.3 loaves of bread
Step-by-step explanation:
Converting 5.5 Ibs to oz (ounces)
1 Ibs =>12 oz
5.5 Ibs => x
Cross Multiply
12 × 5.5 => 88 oz
1 loaf of bread =>12 oz
Hence, in 1 day
12 oz =>1 loaf of bread
88 oz => x
x =>88 oz/ 12 oz
x => 7.3333333333 loaves of bread
Hence, he can make 7.3333333333 loaves of bread in 1 day
Hence, in 7 days
1 day => 7.3333333333 loaves
7 days => x
x => 7 × 7.3333333333 loaves
x => 51.333333333 loaves of bread
Approximately => 51.3 loaves of bread

A bacterial culture grows with a constant relative growth rate. After 2 hours there are 400 bacteria, and after 8 hours the count is 50,000 . (a) Find the initlal population. P(0)= bacteria (b) Find an expression for the population after t hours. P(t)= (c) Find the number of cells after 3 hours. (Round your answer to the nearest integer.) P(3)= bacteria (d) Find the rote of growth (in bacteria/hour) after 3 hours. (Round your answer to the nearest integer.) rho′(3)= bacteriafhour (e) After how many hours will the population reach 200,000 ? (Round your answer to one decimal place.) t= ____ hours
The initial population is 50 bacteria. The expression for the population after t hours is P(t) = 50 * e^(2 * ln(80)) * t. The number of cells after 3 hours is 16,000. The rate of growth after 3 hours is 12,000 bacteria/hour. The population will reach 200,000 after 10.3 hours.
Let P(t) be the number of bacteria after t hours. We know that P(2) = 400 and P(8) = 50,000. We can use these two equations to find the initial population P(0) and the constant relative growth rate k.
P(0) * e^(2k) = 400
P(0) * e^(8k) = 50,000
Dividing these two equations, we get:
e^(6k) = 125
e^k = 5
Therefore, P(0) = 50 and k = ln(5).
The expression for the population after t hours is:
P(t) = P(0) * e^(kt) = 50 * e^(ln(5) * t) = 50 * e^(2 * ln(80)) * t
The number of cells after 3 hours is:
P(3) = 50 * e^(2 * ln(80)) * 3 = 16,000
The rate of growth after 3 hours is:
rho'(3) = P'(3) = 50 * e^(2 * ln(80)) * 2 * ln(80) = 12,000
The population will reach 200,000 after:
t = ln(200,000) / (2 * ln(80)) = 10.3 hours

determine the value of k if g(x) =4x+k is a tangent to f(x)= -x² +8x +20
Answer:
22
Step-by-step explanation:
222
The value of k in the given functions is; 24
What is the value of the function to the tangent?
We are given the functions;
g(x) = 4x + k as a tangent to f(x) = -x² +8x +20
For f(x) = -x² +8x +20
=> f'(x) = -2x + 8
Thus, slope of tangent at ( x , y) = -2x + 8
For g(x) = 4x + k
g'(x) = 4.
Thus, slope is 4
Therefore;
-2x + 8 = 4
-2x = -4
x = 2
Putting 2 for x in f(x) gives;
f(2) = -2² + 8(2) + 20
f(2) = 32
Thus, it is at (2 , 32)
Thus, (2 , 32) lies on g(x) = 4x + k
4(2) + k = 32
k = 32 - 8
k = 24

The production function Yt =A[αK tv v−1+(1−α)N tv v−1] v−1v does not exhibit constant returns to scale.
What is constant returns to scale?The concept of constant returns to scale is a property of production functions. It refers to a situation in which an increase in inputs such as labor, capital, or both results in a proportionate rise in output.
How to determine whether a production function has constant returns to scale?The production function Y = f(K, N) exhibits constant returns to scale if, for all values of K and N, there is a scalar λ such that Y(λK, λN) = λY(K, N)
If this condition holds, then we can say that the production function exhibits constant returns to scale.
Does the production function Yt =A[αK tv v−1+(1−α)N tv v−1] v−1v exhibit constant returns to scale?
Let us determine whether the production function
Yt =A[αK tv v−1+(1−α)N tv v−1] v−1v
exhibits constant returns to scale using the definition above.
Y(λK, λN) = A[α(λK) v (v−1) + (1−α)(λN) v (v−1)] v−1vY(λK, λN)
Y(λK, λN) = A[λvαK v (v−1) + λv(1−α)N v (v−1)] v−1vY(λK, λN)
Y(λK, λN) = A[λvαK v (v−1)v−1v + λv(1−α)N v (v−1)v−1v]Y(λK, λN)
Y(λK, λN) = λvA[αK v−1 + (1−α)N v−1] v
Since λ appears outside the bracket, the production function does not satisfy the condition of constant returns to scale because λ is not eliminated on both sides of the equation.
Therefore, we can conclude that the production function Yt =A[αK tv v−1+(1−α)N tv v−1] v−1v does not exhibit constant returns to scale.

Consider the exponential function with equation A = P(1+r)t
a. Name the independent and dependent variables.
b. What is the growth factor?
The given exponential function equation is A = P(1+r)t, where P represents the principal amount, A represents the final amount, r represents the annual interest rate, and t represents the time in years.a.
The independent variable is t (time in years) while the dependent variable is A (final amount).b. The growth factor can be obtained by dividing A by P. Therefore, Growth factor = A/PLet us assume P=100, r=20%, and t=1. Then we can find A as follows:A = P(1+r)tA = 100(1+0.2)1A = 100(1.2)A = 120Therefore, the growth factor is:A/P = 120/100 = 1.2If we assume P=150, r=5%, and t=2, thenA = P(1+r)t = 150(1+0.05)2= 150(1.1025)= 165.375The growth factor is:A/P = 165.375/150 = 1.1025

Answer:
x = 28/97
y = 532/
Step-by-step explanation:
x + 5y = 20x + 3y
=> 5y - 3y = 20x - x
=> 2y = 19x
=> y = (19x)/2
x + 5y = 14
=> x + 5((19x)/2) = 14
=> x + (95x)/2 = 14
=> (2x + 95x)/2 = 14
=> 97x = 14(2)
=> 97x = 28
=> x = 28/97
=>y = (19x)/2 = (19(28))/(97(2)) = 532/194

if f and g are continuous functions of t on the interval I, then the set of ordered pairs (f(t), g(t)) represent a parametric equation: *x= f(t) and y= g(t) are parametric equations *t is the parameter, I is the parameter interval
The set of ordered pairs (f(t), g(t)) represents a parametric equation where x = f(t) and y = g(t) are the parametric equations and t is the parameter. The interval I represents the parameter interval, within which the parameter t can vary.
In mathematics, parametric equations are a way to represent curves or surfaces by expressing the coordinates of points in terms of one or more parameters. In the context of a plane, a parametric equation consists of two functions, typically denoted as x = f(t) and y = g(t), where t is the parameter and f(t) and g(t) are continuous functions defined on a given interval, I.
By varying the parameter t within the interval I, we can generate a set of ordered pairs (x, y) that correspond to points on the curve or surface defined by the parametric equations. Each value of t determines a specific point (x, y) on the curve, allowing us to trace out the entire shape.
The interval I represents the range of values for the parameter t. It determines the extent over which the curve or surface is defined. By choosing different intervals for t, we can control the portion of the curve or surface that is represented by the parametric equations.
Overall, parametric equations provide a flexible and powerful way to describe curves and surfaces, allowing for a wide range of shapes to be represented and analyzed in mathematics and other fields.

Let f(x) = x2 – 4, x < 0. What is f-1?
the inverse of the function f(x) = x^2 - 4, x < 0, is f^-1(x) = -√(x + 4), x < 4.
To find the inverse of a function, we need to swap the input and output variables and then solve for the output variable.
Let y = f(x) = x^2 - 4, x < 0.
Swapping the input and output variables, we get x = y^2 - 4, y < 0.
Solving for y, we add 4 to both sides and take the square root:
x + 4 = y^2
y = ±√(x + 4)
Since the domain of the original function is x < 0, the range of the inverse function is y < 0. Therefore, we take the negative square root:
f^-1(x) = -√(x + 4), x < 4.

The equation of the line that is parallel to y=-5x+6 and passes through the point (-4,-1) is y = -5x-21.
How do you find slope through given points?Given the coordinates of two points on the line, use the slope formula to get the slope of the line. The slope formula, or the ratio of the change in the y values to the change in the x values, is m=(y2-y1)/(x2-x1). The initial point's coordinates are x1 and y1, respectively. The second points' coordinates are x2, y2.The slope formula rise/run is all that is required to determine slope between two places. With various forms of accessible information about the line, there are many formulas to determine the slope. When two points on the line are known, the formula for finding the slope from two points is particularly utilized.Given data :
Here, given equation of line is y = -5x+6
Required line is parallel to this given line, so we can say that the slope is same for the lines.
General equation of a line be y = mx+c , where m is the slope
Comparing given equation with this equation we get,
m = -5
The required line also passes through the point (-4, -1)
Now, we know that,
m = (y2-y1)/(x2-x1).
⇒ -5 = (-1 - Y ) / ( -4 - x )
⇒ -5 = y + 1 / x + 1
