Answer:
The nth term can be represented by;
Tn = 5n- 1
Step-by-step explanation:
In this question, we are concerned with finding an expression in terms of n for then the term of the sequence.
Mathematically, the nth term of a sequence Tn can be represented by the formula;
Tn = a + (n-1)d
where a is the first term in the sequence which is 4 , and d is the common difference which is the difference between 2 consecutive terms which is 9-4= 5
our n is n, since we do not know the number of terms we are finding for
Plugging these values, we have;
Tn = 4 + (n-1)5
Tn = 4 + 5n -5
Tn = 5n- 1
Answer:
2. 19.47 in
3. 153.86 square centimeters
Step-by-step explanation:
2. The circumference of a circle is π times the diameter, so in this case it is 6.2 * 3.14 = 19.47 in (rounding to nearest hunderdth).
3. The area of a circle is π/4 times the diameter squared, so in this case it is 14^2 * 3.14 / 4 = 153.86 square centimeters.

Answer:
x = 15
Step-by-step explanation:
<u>If angles are complimentary, they add up to 90 degrees</u>
<u />
<u>Step 1: Make an equation</u>
<em>x + (3x + 30) = 90</em>
<em />
<u>Step 2: Solve for x</u>
x + (3x + 30) = 90
x + 3x + 30 = 90
4x + 30 - 30 = 90 - 30
4x / 4 = 60 / 4
<em>x = 15</em>
<em />
Answer: x = 15
Standard formula: Ax + By = C
y = 3x -3 + 2
y - 3x = -1 is the answer
hope this helps
