Ahat [919]

Answer: $\bold{a)\quad 51, 54, 57\qquad a_n=a_{n-1}+3}$

$\bold{b)\quad 250, 625, 1562.5\qquad a_n=(2.5)a_{n-1}}$

Step-by-step explanation:

a) This is an arithmetic sequence where 3 is added to the previous term.

48 + 3 = 51

51 + 3 = 54

54 + 3 = 57

The recursive formula for this sequence is: $a_n = a_{n-1}+3$

*****************************************************************************************

b) This is a geometric sequence where 2.5 is multiplied to the previous term.

100(2.5) = 250

250 (2.5) = 625

625(2.5) = 1562.5

The recursive formula for this sequence is: $a_n=(2.5)a_{n-1}$

If the length of a rectangular television screen is 20 inches and its height is 15 inches,

scoundrel [369]

Use the Pythagorean theorem:

C = √[a^2 + b^2] 
C = √[(20^2 + 15^2] 
C =√[400 + 225] 
C = √(625) 
C = 25 inches 

Answer: 3.25 inches ✔️

Answer:

0.15-0.75p? YES

-0.45-0.6+0.75P? NO

-3(-0.05+0.25p)? YES

-3(0.15)+(-3)(0.2)+(-3)(0.25p)? NO

Step-by-step explanation:

-3(0.15-0.2+0.25p)

=-0.45+0.6-0.75p

=0.15-0.75p

1. 0.15-0.75p=0.15-0.75p? YES

2. -0.45-0.6+0.75P=0.15-0.75p?

-1.05+0.75p=0.15-0.75p? NO

3. -3(-0.05+0.25p)=0.15-0.75p?

0.15-0.75=0.15-0.75p? YES

4. -3(0.15)+(-3)(0.2)+(-3)(0.25p)=0.15-0.75p?

-0.45-0.6-0.75p=0.15-0.75p?

-1.05-0.75p=0.15-0.75p? NO
