#11: First term is 2. Formula for the (n+1)th term is (previous term) + 3.

Thus, we have 2, 5, 8, 11, 14, ... This is an arithmetic sequence with common difference 3.


#12 First term is -4. Formula for the (n+1)th term is (previous term) + n^2.

Second term (n=2): -4 + (2^2) = 0

Third term (n=3) : 0+3^2 = 9

Fourth term (n=4): 9 + 4^2 = 25

Fifth term (n=5) : 25 + 5^2 = 50

Phil is riding his bike. He rides 42 miles in 4 hours, 52.5 miles in 5 hours, and 63 miles in 6 hours. Find the
kvasek [131]

If we take 42/4, or any other of the sets, you will get 10.5, which is k.

10.5 is the amount of miles travelled in 1 hour.

Since we just multiply time and miles to get y, our equation will just be in y=kx format. 10.5 * time is the same as writing 10.5x since x is the hours. y would be miles.

Constant of proportionality: k = 10.5

The equation: y = 10.5x

What is the value of y? ​
olganol [36]

Answer:

26

Step-by-step explanation:

We know that the entire angle measures 66 degrees.

Therefore, angle y plus 40 degrees must equal 66.

In an equation:

y+40=66

To solve for y, subtract 40 from both sides:

y=26\textdegree

So, the measure of angle y is 26 degrees.

And we're done!
