i don't get it (solve)
write the domain and the range of the function as an inequality, using set notation, and using interval notation. also describe the end behavior of the function
the graph of the quadratic function f(x) = -x^2 is shown
When the domain of the function is continuous, a different approach may well be required, although even here we note that in practice, optimization problems are usually solved using a computer, so that in the final analysis the solutions are represented by strings of binary digits (bits).

Answer:
[tex]x=2[/tex]
Step-by-step explanation:
So we have the equation:
[tex]5^x+5^{x+1}=150[/tex]
First, separate the second term:
[tex]5^x+(5\cdot5^x)=150[/tex]
Let u equal 5ˣ. So:
[tex]u+5u=150[/tex]
Combine like terms:
[tex]6u=150[/tex]
Divide both sides by 6:
[tex]u=25[/tex]
Substitute back u:
[tex]5^x=25[/tex]
Take the base 5 logarithm of both sides:
[tex]\log_5(5^x)=\log_5(25)[/tex]
The left cancels:
[tex]x=\log_5(25)[/tex]
Evaluate the right:
[tex]x=2[/tex]
So, our answer is 2.

Bob is hiking down a 12-mile country trail. He could hike at 3 mph for the first two hours and then go the rest of the way at 5 mph or he could just go the whole way at 4 mph. How long would each of these options take? Which option is the faster?
Answer:
The first option will take a total of 3.2 hours while the second option will take just 3 hours
This shows that the second option is faster
Step-by-step explanation:
Here, we want to compare two hiking options and see the one which is faster.
At any point in time;
Distance = speed * time
In the first option, he could hike at 3 mph for two hours.
Total distance covered would be 3 * 2 = 6 miles
Distance left = 12 miles - 6 miles = 6 miles
Time taken to hike 6 miles at 5 mph will be ; 6/5 = 1.2 hours
Total time for the first type hiking = 1.2 hours + 2 hours = 3.2 hours
For the second option;
Time = distance/speed = 12 miles/4 mph = 3 hours
We can see that the second option is faster
Here, we are required to determine how long each of the options take and which of the 2 options is faster .
Therefore;
Therefore;Option 1: 3.2hours
Therefore;Option 1: 3.2hoursOption 2: 3hours.
Therefore;Option 1: 3.2hoursOption 2: 3hours.Ultimately, since option 2 takes 3hours and option 1 takes 3.2hours to hike down the distance respectively, Option 2 is faster.
Total hiking distance = 12 milesFor first option;
He could hike at 3 mph for the first two hours and then go the rest of the way at 5 mph. The statement above suggests that after the first 2 hours, 6 miles will have been covered and the remaining 6 miles can be covered at 5mph in (6/5)hours = 1.2hours.Therefore, the total time taken using this option is;(2 + 1.2) hours = 3.2hours.For second option;
He could go the whole way at 4mph.At this pace, he is able to travel the whole 12mile hiking distance in (12/4)hours.Therefore, the total time taken using this option is; 3hours.Therefore;
Option 1: 3.2hoursOption 2: 3hours.Ultimately, since option 2 takes 3hours and option 1 takes 3.2hours to hike down the distance respectively, Option 2 is faster.

Clara says that if you square the number 4 and then divide the result by 2, you end up with 4. Is Clara correct? Explain. Please help.
Answer:
She is incorrect
Step-by-step explanation:
If you square 4 you get 16 and divide 16 and 2 you get 8 so shes wrong.
Answer: Clara is incorrect
Step-by-step explanation:
The square root of 4 is 2
2 ÷ 2 = 1
You end up with 1 not 4, therefore, Clara is wrong.
Edit: Look at the other answer, I sadly made a mistake thinking the question said square root but it said square I apologize .
"the product of a number and 4"
Answer:
X * 4
Product means the answer after multiplying the factors.
evaluate 207.3×0.04
Let's first just do the multiplication and ignore the decimal points.
2073 x 4 = 8292.
Now there are 3 decimal points we need to consider. So, that gives us an answer of 8.292

If an object travels for 10 seconds at a velocity of 50 feet per second, how far did it travel?
Answer:
500
Step-by-step explanation:
50x10 = 500
50 feet per second so we multiply 50 (the speed per second) by 10 (the time given). You can also use a formula like this:
S x T
S= Speed
T= Time

Three girls-- Kali, Annie, and Xiaoling -- go on a trip with their youth orchestra. The three girls share the cost of the hotel. The bill comes to $295.48. It includes $13.25 for some food that Annie orders and $14.00 for cleaning Xiaoling's uniform. What is the dollar amount of each girl's share of the hotel bill?
Answer:
About $107.57
Step-by-step explanation:
if you add up the bill cost and the 13.25 for the food and 14.00 for cleaning Xialing's uniform its $322.73 divide that between the 3 girls and you get about 107.57
Each girl would pay Kali = $89.41
Annie = $102.66
Xiaoling = $103.41
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
Foe example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Total bill amount = $295.48
Now, the amount excluding the amount of food ordered by Annie
= 295.48 - 13.25
= $282.23
and, the amount excluding Cleaning amount
= 282. 23 - 14
= $268.23
So, Each Girl would pay
Kali = $ 268.23 / 3 = $89.41
Annie = 89.41 + 13.25 = $102.66
Xiaoling = 89.41 + 14 = $103.41

The required equations are 2x − 3=11 and 2x − 3=−11. Option C is correct.
Given that,
To determine what are the two equations to set up to solve the equation |2x−3|=11.
The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The given equation,
| 2x − 3| = 11
2x - 3 = ± 11
Taking (+)
2x - 3 = 11 - - - - - - - (1)
