Answer:

Step-by-step explanation:

1. Un = 3^ n

U1 = 3, U2 = 9, U3 = 27, U4 = 81, U5 = 243

2. Un = (-2/5)^n

U1 = -2/5, U2 = 4/25, U3 = 8/125, U4 = 16/625, U5 = 32/3125

3. Un = sin npi/2

U1 = 1, U2 = 0, U3 = -1, U4 = 0, U5 = -1

4. Un = 3n/n+4

U1 = 3/5, U2 = 1, U3 = 9/7, U4 = 3/2, U5 = 5/3

5. Un =  (-1)^n+1(2/n)

U1 = 1, U2 = 2, U3 = -1/3, U4 = 3/2, U5 = -3/5

6. Un = 2 + 2/n - 1/n^2

U1 = 3, U2 = 11/4, U3 = 23/9, U4 = 39/16, U5 = 59/25

Arrange the following polynomial into descending order for x, then interpret the degree of the 2nd term.
igor_vitrenko [27]
For the answer to the question above,  the power of "y" doesn't influence descending order for x even if it is higher than power of x.

Unordered polynomial is 
7x3y3 + 4 - 11x5y2 - 3x2y

Polynomial in descending order  looks like this
-11x5y2 + 7x3y3 - 3x2y + 4

Degree of the second term is 5 ( because of x5 )

Given: A car travels at a distance of d km. The formula that relates d to t is d=kt

To find: kind of variation

Solution:

The formula that relates d to t is d=kt

Here, k is a constant of proportionality.

Constant of proportionality is also called as constant of variation.

d varies directly as t.

Therefore, this is a direct variation.

What is the answer to this
Arisa [49]

Answer:

x = 20, <S = 47 degrees, <P = 131 degrees

Step-by-step explanation:

27 + x + 119 + 63 + 3x + 71 = 360

4x + 280 = 360

4x = 80

x = 20

<S = 27 + x = 27 + 20 = 47 degrees

<P =  3x + 71 = 3(20) + 71 = 131 degrees

Which ordered pair is a solution of the system ?
drek231 [11]
Hello!

Since we already see an equation that equals y (-2x-4), we can plug that equation into the first to solve for x.

x+4(-2x-4)=19
x-8x-16=19
-7x=35
x=-5

Now that we know the value of x, we will plug it into the second equation to solve for y.

y=-2(-5)-4
y=10=4
y=6

This gives us the answer below

\left \{ {{x=-5} \atop {y=6}} \right.

The correct answer is A) (-5,6)

I hope this helps!
