Use the net to find the surface area of the rectangular prism.

Komok [63]

Answer:

220

Step-by-step explanation:

The surface area is given by

SA = 2 ( lw+wh+lh) where l is length h is height and w is width

SA = 2(3*4 + 3*14+ 4*14)

= 2(12+42+56)

= 2(110)

= 220

F(n)=5.(-2)n-1<br>Complete the recursive formula of f(n).

Alex73 [517]

Answer:

a(n) = $(-2)(a_{n-1})$

$a_{1}=5$

Step-by-step explanation:

The given expression is in the form of the explicit formula of a geometric sequence.

f(n) = $a(r)^{n-1}$

Where 'a' = First term of the sequence

r = common ratio

Recursive formula of a geometric sequence is,

a(n) = $(a_{n-1}).(r)^{n-1}$

a(n) = $(-2)(a_{n-1})$

Where, $a_{1}=5$

So the recursive formula will be a(n) = $(-2)(a_{n-1})$

Find the number that makes the ratio equivalent 1:3 9:_

dimaraw [331]

Answer:

Step-by-step explanation:

If the ratio is 1:3 multiply that by 9:9 so you effectively get 9:9x3 = 9:27. Or, you can say to yourself if B (3) is 3 times greater than A (1) then B is 3 times greater than 9. So 9x3 = 27
