professor190 [17]
The first one would be approximately -0.8. It has a negative slope and the data points are fairly close together. The second one is almost a straight line so it would be very close to 1. I would say 0.97 The closer the data is to a straight line the closer the r value is to 1 or negative 1. Hope this helps.

Identify the 42nd term of an arithmetic sequence where a1 = -12 and a27 = 66
Dmitry_Shevchenko [17]
The arithmetic formula is expressed as an = a1 + d *(n-1)where n is an integer. Substituting from the given a1 = -12 and a27 = 66, 66 = -12 + d *(27-1). hence  , d is equal to 3. a42 thus using the formula is equal to 111. The final answer to this problem is 111.

DF^2=DH^2+HF^2

DF=√DH^2+HF^2

DF=√2(DH^2) {AS IT IS A CUBE THEN ALL SIDES ARE EQUAL}

DF=√2*11^2 {ALL SIDES OF A CUBE ARE EQUAL}

DF=√2*121

DF=√242

DF=15.555
