Use the rule n ÷ 4, where n represents the position of a term in a sequence. Find the first four terms in the sequence.

Ne4ueva [31]

Answer:

a1 = 1/4

a2 = 1/2

a3 = 3/4

a4 = 1

Step-by-step explanation:

an = a/n

then when a= 1, 2, 3, 4

a1 = 1/4

a2 = 2/4 = 1/2

a3 = 3/4

a4 = 4/4 = 1

X+3y = 2

nalin [4]

Answer:

The value of "x" is 5.

Step-by-step explanation:

In order to solve this system of equations, we first have to take the first equation and use it to represent "y" in terms of "x". We do that in the following way...

$x + 3y = 2\\3y = 2 - x\\y = \frac{2}{3} - \frac{x}{3}$

Now, we need to take the second equation and substitute "y" for the equivalent value in terms of "x". After doing this we will get the following equation, which we can solve to get the value of "x".

$4x - 3y = 23\\4x-3(\frac{2}{3} - \frac{x}{3}) = 23\\4x - 2 + x = 23\\5x - 2= 23\\5x = 25\\x = 5$

Therefore, the value of "x" is 5.

Another plan to secure the roller coaster involves placing two concrete struts on either side of the center of the leg of the ro

skelet666 [1.2K]

Answer:

The beam should be placed 8 feet from the center.

Step-by-step explanation:

The struts are y = √(x + 8) and y = √(x − 4). The struts are 2 feet apart at the location of the beam:

√(x + 8) − √(x − 4) = 2

Solving:

√(x + 8) = 2 + √(x − 4)

x + 8 = 4 + 4√(x − 4) + x − 4

8 = 4√(x − 4)

2 = √(x − 4)

x − 4 = 4

x = 8
