What is the sum of a geometric sequence 1,3,9,... if there are 14 terms
Maksim231197 [3]
1, 3, 9, 27, 81, 243, 729, 2187, 6561, 19683, 59049, 177147, 531441, 1594323.
If this is the proper sequence pattern, we add up all the numbers to get a sum.
The total sum is 2391457.

Brianna bought snacks for her team's practice. She bought a bag of oranges for $2.72 and a 20-pack of juice bottles. The total c
posledela

Answer:

each bottle was $2.12 :P

Step-by-step explanation:

➼start by making an equation to find the price of the juice pack, in this case x would be the price of the juice pack because its unknown, the juice pack price(x) added to the price of the oranges(2.72) and equal the total(45.12), the before tax part is not needed info

2.72 + x = 45.12

➼now our aim to get x alone to find out its worth so we will have to do the opposite and subtract 2.72 from everything, since its positive

2.72-2.72=0 crosses out

45.12-2.72=42.4

➼which gets us x = 42.4 so one 20 pack is 42.40 dollars but we arent done yet, to find out the price of EACH bottle we must divide 42.4 by 20!

42.4/20=2.12

➼so to sum it up, each bottle is $2.12 :)

The first steps in writing f(x) = 4x2 + 48x + 10 in vertex form are shown. f(x) = 4(x2 + 12x) + 10 (twelve-halves) squared = 36
brilliants [131]

Answer:

f(x)=4(x+6)^2-134

Step-by-step explanation:

We are required to write the functionf(x) = 4x^2 + 48x + 10 in vertex form.

First, bring the constant to the left-hand side.

f(x) -10= 4x^2 + 48x

Factorize the right hand side.

f(x) -10= 4(x^2 + 12x)

Take note of the factored term(4) and write it in the form below.

f(x) -10+4\Box= 4(x^2 + 12x+\Box)

\Box = (\frac{\text{Coefficient of x}}{2} )^2\\\\\text{Coefficient of x}=12\\\\\Box = (\frac{12}{2} )^2 =6^2=36

Substitute 36 for the boxes.

f(x) -10+4\boxed{36}= 4(x^2 + 12x+\boxed{36})

f(x) -10+144= 4(x^2 + 12x+6^2)

f(x) +134= 4(x+6)^2\\f(x)=4(x+6)^2-134

The function written in vertex form is f(x)=4(x+6)^2-134
