Answer:
Step-by-step explanation:
A. Yes it repeats
Simply change 1/4 to a decimal
1/4 = 0.25
now we can multiply 0.25 and 32
lets do the math:)
0.25 x 32 = 8
your answer = 8
When in doubt, eat a pineapple :)
Answer:
Tn = -n^2 - n + 21 is the formula for the nth term.
Step-by-step explanation:
The second differences are all equal in this quadratic sequence.
Now, the quadratic sequence has a formula of Tn = an^2 + bn + c
Find the value of a in an^2 by dividing the difference by 2:
-2/2 = -1
a = -1
Since T1 is 19 and T2 is 15 we can put that into the equation and simplify:
b + c = 20
2b + c = 19
Thus, b = -1 , c = 19 and the general formula for the nth term is Tn = -n^2 - n + 21
Answer:
10π
Step-by-step explanation:
The circumference of a circle is the distance of the outside of the circle. The formula for circumference is C=2πr.
In the question, you are given the diameter. Diameter is the radius times 2. So, to find the radius you can divide the diameter by 2. Since, 10cm/2 is 5 cm, 5cm is the radius.
Then, plug this information into the formula to solve for C.
This means that, in terms of pi, the circumference is 10π cm.
Answer:
y = (3/2)x -3
Step-by-step explanation:
y = mx + b, where m = slope and b = y-intercept
The slope is 3/2 and the y-intercept is (0, -3)
y = (3/2)x -3
