The infinite sum is (first term) divided by (1 minus the common ratio). The first term is 6(1/4) = 3/2; the common ratio is 1/4:
[tex]S=\frac{\frac{3}{2} }{1-\frac{1}{4} } =\frac{\frac{3}{2} }{\frac{3}{4} } =(\frac{3}{2} )*(\frac{4}{3} )=2[/tex]
The terms after n=16 are tiny and will certainly bring the sum down only a tiny bit.
So to the nearest whole number the sum of the finite geometric series is 2.
2 more than the difference between 8 and h

7x+4y=
16 42x+24y
=110
Answer:
No solution (C)
Step-by-step explanation:
System of Linear Equations given :
[1] 7x + 4y = 16
[2] 42x + 24y = 110
Solve by Substitution :'
// Solve equation [2] for the variable y
[2] 24y = -42x + 110
[2] y = -7x/4 + 55/12
// Plug this in for variable y in equation [1]
[1] 7x + 4•(-7x/4+55/12) = 16

A swimming pool has a length of 28 feet, a width of 16 feet, and a depth of 7 feet.
How much water can the swimming pool hold?
Answer:
The pool can hold 3,136 cubic feet of water
Step-by-step explanation:
To know how much water the pool can hold, we need to find the volume of this swimming pool, because the volume is how much a container can hold.
The formula for volume is L*W*H (length times width times height)
Let's multiply!

The equation having a sum that is a whole number is 0/5 + 1/5 + 2/5 + .... + 5/5
What is an whole number?A whole number means a number that does not include any fractions, negative numbers or decimals.
Given that, number sentences show a pattern in the sum of the fractions from 0 to 1 for different denominators,
1) 0/5 + 1/5 + 2/5 + .... + 5/5 =
1/5(0 + 1 + 2 + 3 + 4 + 5) = 1/5(15) = 3 [whole number]
2) 0/6 + 1/6 + 2/6 + .... + 6/6 =
1/6(0 + 1 + 2 + 3 + 4 + 5 + 6) = 21/6 = 7/2 [fraction]
3) 0/8 + 1/8 + 2/8 + .... + 8/8 =
1/8(0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8) = 36/8 = 9/2 [fraction]
4) 0/12 + 1/12 + 2/12 + .... + 12/12 =
1/12(0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12) = 78/12 = 13/2 [fraction]

please help me with this
When a line increases as you read it from left to right, the slope of the line is negative.
When the slope of a line is negative, the y-values decrease as the x-values increase.
The slope of a line is always positive.
The slope of a line is never 0.

please PLEASE help me!!! Write an expression that can be used to produce vector r from vectors p and q. Explain how you determined that expression
Answer:
r = p - q
Step-by-step explanation:
Write the two given vectors using i and j components.
i = unit vector in x direction
j = unit vector in y direction
p = -i - 3j
q = 3i - 4j
Now how can you combine these two vectors and get r when
r = -4i + j?
Adding p and q gives this:
p + q = -i - 3j + 3i - 4j = 2i - 7j
That is not r, so the addition of the vectors p and q does not work.
How about subtraction?
Start with -i from p and subtract 3i from q. You do get -4i which is the x-component of r.
Then start with -3j from p and subtract -4j from q. You get -3j - (-4j) = -3j + 4j = j which is the y-component of r.
That subtraction works.
p - q = -i - 3j - (3i - 4j) = -i - 3j - 3i + 4j = -4i + j which is exactly what r is.
Answer: r = p - q

¿Cuál es la quinta parte de dos terceras de 180? HELP!!
Answer:
24 is the answer
Step-by-step explanation:
To solve this problem, we first do two thirds of 180, and then we do one fifth of the solution you got for "two thirds of 180"
[tex]\mathrm{Two\:thirds\:of\:180 = (\frac{2}{3}) 180\:\:or\:\:\frac{2}{3}\times180}[/tex]
[tex]\mathrm{Turn\:\frac{2}{3}\:into\:a\:decimal,\:by\:dividing\:2\:by\:3}[/tex]
[tex]\mathrm{0.6666666666666667\times180}[/tex]
[tex]\mathrm{Multiply\:0.6666666666666667\:and\:180}[/tex]
[tex]\mathrm{120}[/tex]
Now we do one fifth of 120
[tex]\mathrm{One\:fifth\:of\:120 = (\frac{1}{5})120\:or\:\frac{1}{5}\times120}[/tex]
[tex]\mathrm{Turn\:\frac{1}{5}\:into\:a\:decimal,\:by\:dividing\:1\:by\:5}[/tex]
[tex]\mathrm{0.2\times120}[/tex]
[tex]\mathrm{Multiply\:0.2\:and\:120}[/tex]
[tex]24[/tex]
So the answer to "What is one fifth of two thirds of 180", would be 24
By multiplying the number by the corresponding fractions, we can see that the fifth part of two-thirds of 180 is 24.
How to get the fifth part of two thirds of 180?The fifth part of two-thirds of 180 is 24.
To calculate it:
Step 1: Find two-thirds of 180, Just multiply the fraction 2/3 by the number
(2/3) * 180 = 2 * 180 / 3 = 360 / 3 = 120
Step 2: Find the fifth part of the result from Step 1, similar like we did above, multiply the number by the fraction 1/5.
(1/5) * 120 = 120 / 5 = 24
So, the fifth part of two-thirds of 180 is 24.

Step-by-step explanation:
When evaluating a piecewise function, the fist step is to determine the applicable domain. Then the function defined for that domain is the one that is used for the evaluation.
A.x = 0 is in the domain x < 5, so the applicable function is f(x) = x+4.
f(0) = 0 +4 = 4

B.x = 6 is in the domain 5 ≤ x < 7, so the applicable function is f(x) = 8.
