Use the tangent ratio for the angle: tan 34 = b/16. Now multiply both sides by 16 to get 16 tan 34 = b or b = 10.79. Choice A above
So we look at the conditions
if x<1 and if x≥1
x<1 means x is less than 1
x≥1 means x is greater than 1 including 1
that includes all real numbers
so domain is all real numbers
range is (sart with top and go up, if x=1 then f(1)=7 so from 7 to infinity, then other one, x<1, -inifinity to 4 not including 4
so the range with interval notation is (-∞,4) U [7,∞)
graph is the graph of each, but pt together (see attachmetn)
Answer:
105°
Step-by-step explanation:
We are supposed to find the angle between the hour hand and the minute hand at a time of 2:30 in a 12 hour analog clock.
So, we have 12 segments in a clock , each segment corresponding to an hour.
Angle of each segment would be :-
At 2:30 the minute hand will be facing 6 hour direction and the hour hand between hours 2 and 3.
So the angle between them would be
So the angle between the hour and the minute hand at time 2:30 is 105°.
The value of:
4/5÷4/5
will be:
4/5÷4/5
Note that when you divide fractions you multiply the first fraction by the reciprocal of the second one.
=4/5×5/4
=1
