The range of the function f(x) : is y > 0.
The correct option is (A)
The definition of range is the set of all possible values that the function will give when we give in the domain as input.
Given function is :
If we draw the graph for this, then we can see that the horizontal asymptote is 0.
So, the range is real numbers higher than 0.
Hence, the range should be y > 0.

The measure of angle ABC tangent chord angle is 117°.
Tangent of a circle is defined as the line that passes through exactly one point on the circle.
Chord is the line segment that has it's two end points on the circle.
A chord AB is drawn.
AXB is one of the arc which measures 234°.
We have to find the angle that a tangent through B makes with chord AB.
This measure will be half of the arc measure.
Angle ABC = 234° / 2 = 117°
Hence the measure of the angle ABC is 117°.

3 hours and 15 minutes
3 hours and 45 minutes
4 hours, and 15 minutes
The elapsed time between 4:25 and 7:40 is 3 hours and 15 minutes.
Given that two times 4:25 and 7:40, we need to calculate the time elapsed between these two.
To calculate the elapsed time between 4:25 and 7:40, you need to subtract the starting time from the ending time.
First, let's calculate the difference in hours. From 4:25 to 7:40, we can see that the hours have changed from 4 to 7, which means 3 hours have passed.
Next, let's calculate the difference in minutes. From 4:25 to 7:40, the minutes have changed from 25 to 40.
This means that an additional 15 minutes have passed.
Therefore, the elapsed time between 4:25 and 7:40 is 3 hours and 15 minutes.

The price of the car goes down or will decrease in order to increase the demand of the supplied cars.
It is given that:
A car manufacturer rolled out a new car priced at $10,000, but not many people bought it.
So, in context of the supply and demand if the the demand decreases the price of the item also decreases and hence by doing so if the price of an item decreases the demand again will increase.
Hence, with the decrease in demand:
The price of the car will decrease.
choosing ten students from a box that contains the names of the entire group
choosing five students each from seventh and eighth grade
choosing five female students and five male students
Answer:
Choosing ten students from a box that contains the names of the entire group
Step-by-step explanation:
If each and every unit has equal chance of being selected in a sample then it is called Random Sampling. Here choice of sample should be unbiased and independent.
Option (a) is incorrect because here selection of student is not independent as only those students are choosing who also participate in music class.
Option (b) is correct option as selection of students are independent and unbiased. Also here each student has equal chance of being selected in sample.
Option (c) can't be chosen as selection of student is done from particular cluster.
Option (d) is also incorrect as here we put condition of male and female students.
