Answer:
2+3n
Step-by-step explanation:
This question is based on a topic called sequence and series,under which we have the arithmetic progression
The formula for arithmetic progression is a+(n-1)d
In which a is the first number,n is the nth term and d is the difference
Back to the question
a=5,n=it's not given,d=3
Using the general formula
a+(n-1)d
5+(n-1)3
Open the bracket first
5+3n-3
Collect like terms
5-3+3n
2+3n
The answer is 2+3n
And it can be solved further only if we are given the value of n...the question even stated that we should solve in terms of n
Therefore the answer is 2+3n
Here, you do the same as the previous one, keeping in mind that X cuts TW in a 2:1 ratio.
Answer:
7:16 P.M.
Step-by-step explanation:
24/90=4/15. There are 60 minutes in an hour, so we have 240/15=16.
Answer:
(x-5)² + (x-6)² = 9
Step-by-step explanation:
Remember that the equation of a circle is (x - h)² + (x - k)² = r², with <em>r </em>being the radius and <em>(h,k) </em>being the center point of a circle.
Since we are already given <em>r </em>and <em>(h,k)</em>, all we need to do is plug them into the formula to find our equation.
Answer:
Step-by-step explanation:
According to congruent chords and arcs theorem, if 
then 
.
This means that 
Thus:
(full circle = 360°)
Plug in the values into the equation
Add like terms
Subtract 36 on both sides
Divide both sides by 12
