Answer:
Step-by-step explanation:
So, the point of this is to make x the only thing on one side, so we can see what x is!
Okay so first subtract 8 on both sides...
5x= 25
Now we need to divide on both sides!
That equals...
x=5
So now we know that x=5!
Hope this helped!! :D

Answer:
Below in bold.
Step-by-step explanation:
y = -4x2 + 8x - 13
Divide first 2 terms by -4:-
y = -4(x^2 - 2x) - 13
Convert to vertex form by completing the square:
y = -4[(x - 1)^2 - 1] - 13
y = -4(x - 1)^2 + 4 - 13
y = -4(x - 1)^2 - 9 <---------- Vertex form
y = a(x - j)^2 + k <---------- General form with vertex = (j, k).
So comparing, we see that the vertex is (1, -9).
Step-by-step explanation:
Part A, Option 1 is a exponential function while option is a linear equation.
Part B, Let y=b*a^(x) be the function for option 1. At x=1, y=1100 and at x=2, y=1210. 1100=b*a and 1210=b*a^2. Dividing them both we get, b=1.1 and a=1000. y=1000*(1.1)^(x). For option 2, it's a linear equation with a function y(x)=1000+100x.
The 20 year difference would be immense. With option 1, Belinda will get $6727.5 whereas with option 2, they will end up with $3000
Answer:
20
Step-by-step explanation:
Let = the number of problems Anna completed
<u>Using ratios</u>
5 : 8 = : 32
Cross multiply: 5 x 32 = x 8
160 = 8
Divide both sides by 8: 20 =
Therefore, Anna completed 20 problems.
Fermi Paradox depends most directly on (C) extraterrestrial technology would develop at roughly the same rate as a human technology.
<h3>
What is Fermi Paradox?</h3>
- The Fermi paradox refers to the disagreement between the lack of clear, obvious evidence for extraterrestrial life and various high estimates for its existence.
- According to a 2015 article, "If life is so easy, someone from somewhere must have called by now."
- Enrico Fermi, an Italian-American physicist, is associated with the paradox as a result of a casual conversation with fellow physicists Edward Teller, Herbert York, and Emil Konopinski in the summer of 1950.
- Walking to lunch, the men talked about recent UFO sightings and the possibility of faster-than-light travel.
To find the correct option:
- "According to Fermi's argument, it is extremely unlikely that many other civilizations discovered science at the same time we did.
- If they had discovered science even a thousand years before us, they could be so far ahead of us that they are already colonizing our solar system." -
- This statement from the first passage implies that the Fermi Paradox's basic assumption is that extraterrestrial technology will develop at the same rate as our technology.
- Fermi's argument maintains the above-quoted claim that extraterrestrial technology develops at the same rate as a human technology.
- As a result, C is the best option.
Therefore, Fermi Paradox depends most directly on (C) extraterrestrial technology would develop at roughly the same rate as human technology.
