El primer término de una progresión geométrica es 3 y el séptimo 12 288. Hallar la suma de los siete términos.
Answer:
16383
Step-by-step explanation:
El primer término de la progresión geométrica es 3 y lo llamaremos [tex]a[/tex].
Se tiene que una progresión geométrica es de la forma:
[tex]a, ar, ar^2, ar^3, ar^4, \cdot \cdot \cdot[/tex]
Donde [tex]r \neq 0[/tex] y es la proporción es común. Por lo tanto si el séptimo número de la sucesión es 12.288 este se puede re-escribir como:
[tex]ar^6 = 12.288[/tex]
Si se resuelve la ecuación para hallar [tex]r[/tex] se tiene
[tex]r = \sqrt[6]{\frac{12.288}{a} } = \sqrt[6]{\frac{12.288}{3} } = \sqrt[6]{ 4096} = 4[/tex]
Ahora se halla cada número de la progresión geométrica entre 1 y 7 para finalmente sumarlos
[tex]ar^0+ar^1+ar^2+ar^3+ar^4+ar^5+ar^6[/tex]
[tex]3+12+48+192+768+3072+12288[/tex] = 16383
Por lo tanto la sumatoria de los primeros [tex]7[/tex] términos de la sucesión son 16383

The function f(x) = -2x^5 + x^3 - 7x is an odd function. Which rule is satisfied by this function?
A. f(x) = f(-x)
B. f(x) = -f(x)
C. -f(x) = f(-x)
D. f(x) = f(x)^-1
[tex]f(x) = -2x^5 +x^3 -7x \\\\-f(x) =-(-2x^5 +x^3 -7x) = 2x^5 -x^3 +7x = x(2x^4 - x^2 +7)\\\\f(-x) = -2(-x)^5 + (-x)^3 -7(-x) = 2x^5 -x^3 +7x = x(2x^4 -x^2 +7) \\\\\\\text{Hence,} ~ -f(x)=f(-x)[/tex]

Step-by-step explanation:
Hope this helps!
The tile "type of industry" matches with "retail", "purpose of the business" matches with" sell beautiful, low priced furniture", "how the business can increase profits" matches with "lower operational costs".
What is operational cost?Operational cost is the amount of expenditure done by the company or a firm on its day to day operations or in its manufacturing related activities.
How to identify statements?First tile says "type of industry". In the options there are two options with which it can match one is "retail" and other one is "sell beautiful,low priced furniture".But the second one is related to cheap pricing which may may be just a segment in an industry, that's why the most important option which matches with it is "retail". Second tile matches with "sell beautiful , low priced furniture" because there is a possibility that the business wants to just working for poor or middle class people. For third tile there is not any option present. Fourth tile matches with "lower operatonal costs" because when the cost of the company reduces it automatically increases the profits of the company.

In △ABC, m∠A = 75° and m∠C = 20°, What is m∠B?
Answer:
30 degree ok please make me brainliest
Answer:
∠ B = 85°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , that is
∠ A + ∠ B + ∠ C = 180° , substitute values
75° + ∠ B + 20° = 180°
∠ B + 95° = 180° ( subtract 95° from both sides )
∠ B = 85°

p2q+2q=11
Question 5 options:
Combine p2q+2q
Divide the whole equation by 11.
Divide the first term by p2
Factor a q out of p2q+2q
Answer:
D: Factor a q out of p^2 q+ 2q
Step-by-step explanation:
I took the test. Hope it was helpful! :)
The first step in solving this equation p²q+2q=11 for q will be to factor q out of p²q+2q. Option D is correct.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, the equation is,
p²q+2q=11
Take q common from the L.H.S as
q(p²+2)=11
The value of q is obtained by rearranging the equation as,
q=11/(p²+2)
The value of q obtained after solving the equation p²q+2q=11 will be q=11/(p²+2).
Thus, the first step in solving this equation p²q+2q=11 for q will be to factor q out of p²q+2q. Option D is correct.

On a busy construction site at 1:00 p.m. the sound level is 124 dB, while at 4:00 p.m. it is 100dB. How
many times as intense as the sound of the construction site at 4:00 p.m. is the sound at 1:00 p.m.?
Answer:
1.24 times as intense
Step-by-step explanation:
The intensity of the sound decreases by 24% at construction site from 4:00 p.m. to 1:00 p.m.
What is the average rate of change?Let the function y = f(x).
Then the average rate of change will be
Average rate of change = (y₂ - y₁) / (x₂ - x₁)
On a busy construction site at 1:00 p.m. the sound level is 124 dB, while at 4:00 p.m. it is 100dB.
Then the intense as the sound of the construction site at 4:00 p.m. is the sound at 1:00 p.m. will be
⇒ (100 – 124) / 100
⇒ -0.24
Then the intensity of the sound decreases by 24% at construction site from 4:00 p.m. to 1:00 p.m.

(2x - 4)^2 can be looked at like this (2x - 4)(2x - 4) which can then be foiled
4x^2 -8x + 16, I presume that there is no equals zero so I don't think I can use the quadratic formula.

What is unit conversion?
Unit conversion is the process of changing a physical quantity from one unit of measurement to another. For example, converting kilometers to miles, Celsius to Fahrenheit, or liters to gallons. The process involves multiplying or dividing the original measurement by a conversion factor, which is a ratio of equivalent units
To convert miles to yards, we need to multiply by the conversion factor of 1 mile = 1760 yards.
15 miles * 1760 yards/mile = 26,400 yards
So, the electrician will use 26,400 yards of cable.
Hence, 26400 yards of cable is used.
the answer is B) 26,400

Step-by-step explanation:
Answer:
The first and second one is no
Step-by-step explanation:
(1/5) to the second power is 1/25 and adding 25/25 gets 26/25 which is not equal to 24/25
1 to the second power is still one and (1/4) to the second power is 1/16. 16/16 plus 1/16 is 17/16 which is not equal to 25/26
Towns A, B, C, and X are located along a straight highway. Town B is between A and C, and the distance from A to C is
41 miles. BC is 2 miles more than twice AB.
Town X is between A and B, 6 miles from A. Find XC.
a. 13 miles
c. 41 miles
b. 28 miles
d. 35 miles
Answer: 35 miles, but this is not an answer option.
Step-by-step explanation:
A X B C
AC = 41 miles
BC = 2AB + 2
AX = 6
AX + XC = 41 [This is the key equation. We want XC and AX is given as 6]
6 + XC = 41
XC = 35 miles
None of the answer options show this value.
I don't know why, since:
a. "the distance from A to C is 41 miles." means AC = 41, and
b. "Town X is between A and B, 6 miles from A" means AX = 6
If we say that AX + XC = 41, then 6 + XC = 41 and XC = 35
I don't know why this would be incorrect, so I'll leave it to someone else to spot the problem.
