An object at rest begins to rotate with a constant angular acceleration.
An object at rest begins to rotate with a constant angular acceleration exhibits ANGULAR VELOCITY. This velocity can be estimated as angular displacement divided by the change in time.
Angular velocityAngular velocity refers to the time rate at which a particular object rotates on its own axis.
Angular velocity can be estimated as angular displacement and then divided by the change in time.
This measurement (angular velocity) can be considered a vector quantity because it has both magnitude and direction.

What is the equation of the quadratic function with a vertex at (2,–25) and an x-intercept at (7,0)? f(x) = (x – 2)(x – 7) f(x) = (x + 2)(x + 7) f(x) = (x – 3)(x + 7) f(x) = (x + 3)(x – 7).
Answer:
D. f(x) = (x + 3)(x – 7)
The equation of the quadratic function with a vertex at (2,-25) and an x-intercept at (7,0) is f(x) = [tex](x - 2)^2[/tex] - 25.
What is quadratic function?A quadratic polynomial in mathematics is a polynomial of degree two in one or more variables. The polynomial function defined by a quadratic polynomial is known as a quadratic function.
The vertex form of a quadratic function is f(x) = a[tex](x - h)^2[/tex] + k, where (h,k) is the vertex of the parabola.
Given that the vertex is (2,-25), we have h = 2 and k = -25. So, the quadratic function has the form:
f(x) = a[tex](x - 2)^2[/tex] - 25
We also know that the x-intercept is (7,0). This means that when x = 7, f(x) = 0. So we can substitute these values into the equation and solve for a:
0 = a[tex](7 - 2)^2[/tex] - 25
0 = 25a - 25
25a = 25
a = 1
Substituting a = 1, h = 2, and k = -25 into the vertex form equation, we get:
f(x) = [tex](x - 2)^2[/tex] - 25
Therefore, the equation of the quadratic function with a vertex at (2,-25) and an x-intercept at (7,0) is f(x) = [tex](x - 2)^2[/tex] - 25.

A researcher is interested in the effect of exercise on stamina in elderly patients. The patients are randomly assigned to be in a high-exercise or low-exercise training program for eight weeks. At the end of the program, their stamina is measured by seeing how long they can walk comfortably on a treadmill. In this study, the dependent variable is.
The dependent variable in this given study is; Stamina of the patients
Dependent and Independent VariablesA dependent variable is a variable that depends on the outcome of another variable whereas an independent variable doesn't depend on the outcome of another measured variable.
Now, in the question, we are told that the patients are selected randomly in a high-exercise or low-exercise training program for eight weeks.
This means that the independent variable is the exercise program as it doesn't depend on another measured variable.
However, the stamina being measured from the exercise program is the dependent variable as it depends on the exercise program results.

Chujai's weekly income allowance for snacks is 300 baht and she buys 5 bars of chocolate per week. When her income increases to 330 baht, chujai buys 6 bars per week. The income elasticity of chujai's demand for chocolate is about:.
The income elasticity of chujai's demand for chocolate is about 2, which shows that its a normal good.
What is Income Elasticity ?
Income elasticity of demand is defined as ratio of change in quantity demanded over changes in income.
Income elasticity of demand = Change in quantity demanded / Change in income
Change in quantity demanded =New qty- old qty/ old qty
=( 6 - 5 )/ 5
= 1 / 5
= 0.5
Change in income= New income - old income/ old income
= (330baht - 300baht) / 300baht
= 30 / 300
= 0.1
Therefore, Income elasticity of demand = 0.5 / 0.1 = 2
We can see that the income elasticity of demand is positive( +2)
We can conclude that the chocolate that Chujai spends on is a normal good.
