Mathematics

bixtya [17]3 years ago

The zeros of a quadratic function are found where the graph intersects the x-axis. If the graph interects the x-axis in 2 places, we have 2 real solutions; if the graph intersects--or just touches--the x-axis in one place we have one real solution multiplicity 2; if the graph doesn't go through the x-axis at all we have 2 imaginary solutions. Ours goes through the x-axis in 2 places so we have 2 real solutions. Choice A.

A golf ball is hit from the ground, and its height in feet above the ground is modeled by the function h(t) = -16t^2 + 180t, whe
Aloiza [94]
The time that the ball is in the air is 2x the time that it takes to reach the maximum value.

In order to find the time at the max value you use the equation -b/2a where b is the value attached to the t and a is the value attached to t^2. 

therefore, the time at the max value is -180/(2)(-16)=5.625 seconds

Total time= (5.625)(2)=11.25

A researcher is interested in the relationship between leisure time physical activity, diet, extracurricular activities and hour
Vaselesa [24]

Answer:

The only dependent variable in this research work is the cardiovascular fitness.

The independent variables include leisure time, physical activity, diet, extracurricular activities and hours of sleep.

The relationship or difference between them is simple, the researcher believes that the cardiovascular fitness depends on all of the other variables described above.

Step-by-step explanation:

In an experiment, the independent variable is the variable whose values or qualities are not determined by any of the other variables present in the experimental study.

While a dependent variable is the variable whose values or qualities are determined by one or more other variables present in the experimental setup.

Dependent variables depend on the independent variables.

Just like here, the researcher hopes to learn how much dependence of cardiovascular fitness (dependent variable) is on leisure time, physical activity, diet, extracurricular activities and hours of sleep (the independent variables whose values or qualities are not determined by any other variable in the study).
