Which of the following recursive formulas represent the same arithmetic sequence as the explicit formula an=5+(n-1)2

sergey [27]

Answer:

Choice A:

$a_1=5$

$a_{n}=a_{n-1}+2$

Step-by-step explanation:

$a_n=5+(n-1)2$

means we looking for first term 5 and the sequence is going up by 2.

In general,

$a_n=a_1+(n-1)d$

means you have first term $a_1$ and the sequence has a common difference of d.

So it is between the first two choices.

The explicit form of an arithmetic sequence is: $a_n=a_1+(n-1)d$

An equivalent recursive form is $a_n=a_{n-1}+d \text{ where } a_1 \text{ is the first term}$

So d again here is 2.

So choice a is correct.

$a_1=5$

$a_{n}=a_{n-1}+2$

Select the correct answer from each drop-down menu. The base of pyramid A is a rectangle with a length of 10 meters and a width

ASHA 777 [7]

Step-by-step explanation:

The formula of a volume of a pyramid:

$V=\dfrac{1}{3}BH$

B - base area

H - height

H - height of pyramids

Pyramid A:

$B=(10)(2)=200\ m^2$

$V_A=\dfrac{1}{3}(200)H=\dfrac{200}{3}H\ m^3$

Pyramid B:

$B=10^2=100\ m^2$

$V_B=\dfraC{1}{3}(100)H=\dfrac{100}{3}H\ m^3$

$V_A>V_B\\\\V_A=2V_B$

The volume of the pyramid A is twice as large as the volume of the pyramid B.

The new height of pyramid B: 2H

The new volume:

$V_{B'}=\dfrac{1}{3}(100)(2H)=\dfrac{200}{3}H\ m^3$

The volume of the pyramid A is equal to the volume of the pyramid B.

(-x+4y = 10 ( x — Зу = 11 using substitution

Basile [38]

Answer:

x=74, y=21. (74, 21).

Step-by-step explanation:

-x+4y=10

x-3y=11

-------------

y=21

x-3(21)=11

x-63=11

x=11+63

x=74
