2- recursive formula

1- common ratio

3- explicit formula

4- geometric sequence

5- preceding term

Step-by-step explanation:

1. The fixed amount multiplied by a term to get to the next term in a geometric sequence - Common ratio

2. Defines the next term in a sequence by using the proceeding term - Recursive formula

3. Defines the term with direct computation for any term in the sequence - Explicit formula

4. A sequence in which there is a common ratio between the terms - Geometric sequence

5. The term that is immediately before - Preceding term

A riverboat travels downriver (with the current) at a speed of 15 km/h. The current is 3km/h. To someone on the shore, how fast

Rom4ik [11]

Answer:

18km/h

Step-by-step explanation:

if the riverboat is already going 15 km/h and the current is 3km/h then you should add and you get 18 km/h

If x2=7 what is a value of x? A.√7 B.3.5 C.√49 D.14

ikadub [295]

Answer:

x = sqrt(7) or x = -sqrt(7) thus of the choices you have A:

Step-by-step explanation:

Solve for x:

x^2 = 7

Take the square root of both sides:

Answer: x = sqrt(7) or x = -sqrt(7)

Evaluate the following expression, when n=-3 and r=-8 −5 + 3(−2r + 4n) Pease answer ASAP

Hunter-Best [27]

Answer:

-8

Step-by-step explanation:

Given that,

n = -3

r = -8

Now we have to find the value of the given expression.

For that, you have to replace n and r with ( -3 ) and ( -8 ) respectively.

Let us solve now.

−5 + 3 ( −2r + 4n )

-5 + 3 ( -2 × -8 + 4 × -3 )

-2 ( 16 - 12 )

-2 × 4

-8

Let me know if you've any other questions. :-)

What is the recursive rule for this geometric sequence? 1/2, -2, 8, -32

Gnesinka [82]

Answer:

see explanation

Step-by-step explanation:

A recursive rule allows us to find the term in a sequence from the previous term.

From the given geometric sequence find r the common ratio

r = $\frac{-2}{\frac{1}{2} }$ = $\frac{8}{-2}$ = - 4

Hence recursive rule is

$a_{n+1}$ = - 4 $a_{n}$ ( a₁ = $\frac{1}{2}$ )
