When comparing x^2 + 10 and x + x + x equals to:
x^2 +10 is greater than x + x + x when x = -5
Because -5^2 + 10 = 25 + 10 = 35
and -5 + -5 + -5 = -15
So, 35 > -15

Answer:

1, 2, 8, 128, 32768

Step-by-step explanation:

$recursive \: formula: \\ a _{n} = 2. {( a_{n - 1} )}^{2} \\ \\ a _{1} = 1...(given) \\ \\ a _{2} = 2. {( a_{2 - 1} )}^{2} = 2 {(a _{1} )}^{2} = 2 {(1)}^{2} \\ \\ a _{2} = 2\\ \\a _{3} = 2. {( a_{3 - 1} )}^{2} = 2 {(a _{2} )}^{2} = 2 {(2)}^{2} \\ \\ a _{3} = 8\\ \\a _{4} = 2. {( a_{4 - 1} )}^{2} = 2 {(a _{3} )}^{2} = 2 {(8)}^{2} \\ \\ a _{4} = 128\\ \\a _{5} = 2. {( a_{5 - 1} )}^{2} = 2 {(a _{4} )}^{2} = 2 {(128)}^{2} \\ \\ a _{5} = 32,768\\ \\$

Thus the first five terms are: 1, 2, 8, 128, 32768.

At 1:00, the minute and hour hands form a 30º angle. What is the measure of the angle at 8:00, in degrees?

Anvisha [2.4K]

The angle would be obtuse. So it would be over a 90* angle.
•1= 30*
•2= 60*
•3=90*
•4=120*
•5=150*
•6=180*
•7=210
•8=230*
