At the height of 2467.2 meters from the earths surface, the air pressure equals 50% of the air pressure at the surface of the Earth.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is that air pressure may be represented as a function of height (in meters) above the surface of the Earth, as shown below -
P(h) = P[tex]e^{-0.000122h}[/tex]
where {P} is the air pressure at the surface of the Earth, and his the height above the surface of the Earth, measured in meters.
For 50% of the air pressure at the surface of the Earth, we can write -
50P/100 = P[tex]e^{-0.000122h}[/tex]
1P/2 = P[tex]e^{-0.000122h}[/tex]
1/2 = [tex]e^{-0.000122h}[/tex]
- 0.000122h = log(1/2) = - 0.301
h = - 0.301/- 0.000122
h = 2467.2 meters
Therefore, at the height of 2467.2 meters from the earths surface, the air pressure equals 50% of the air pressure at the surface of the Earth.

Eduardo is in 8th grade and gets an allowance of $10 every week from his parents. He has saved up $110 so far in a savings account. He wants to buy some new clothes since his current wardrobe is getting worn out. He sets a budget of $250 for himself.
a: How much more money does Eduardo need before he can go shopping?
b: How many months will it take Eduardo to save this much money?
c: What trade offs might Eduardo need to make if he wants to buy the clothes in exactly 3.5 months?
Answer:
He has. saved up $110 so far in a savings account. He wants to buy some new clothes since his current wardrobe is getting worn out.
Step-by-step explanation:
a. Eduardo needs $140 more before he can go shopping.
b. 3.5 months will it take Eduardo to save this much money.
c. Eduardo will need to make thoughtful decisions about how he manages his money and balances his spending with his savings goal.
a. Here, we have to find out how much more money Eduardo needs before he can go shopping, we need to calculate the difference between his budget and the amount he has saved:
Remaining money needed = Budget - Saved amount
Remaining money needed = $250 - $110
Remaining money needed = $140
So, Eduardo needs $140 more before he can go shopping.
b. To determine how many months it will take Eduardo to save $140, we can divide the remaining amount by his weekly allowance:
Number of weeks to save $140 = Remaining money needed / Weekly allowance
Number of weeks to save $140 = $140 / $10
Number of weeks to save $140 = 14 weeks
Since there are approximately 4 weeks in a month, we can convert weeks to months:
Number of months = Number of weeks / 4
Number of months = 14 weeks / 4
Number of months = 3.5 months
c. If Eduardo wants to buy the clothes in exactly 3.5 months, he will need to consider some trade-offs to meet his savings goal on time:
Cutting Expenses: Eduardo might need to cut down on unnecessary expenses, like snacks or entertainment, to save more money each week.
Additional Income: He could explore opportunities to earn extra money, such as doing chores or odd jobs for neighbors, to supplement his allowance.
Delayed Purchases: Eduardo could delay spending money on non-essential items until he reaches his savings goal. This might mean postponing purchases that can wait.
Adjusting Budget: Eduardo could reconsider his budget to see if there are any areas where he can reduce spending further to meet his goal faster.
Savings Prioritization: Eduardo could prioritize his savings over other purchases and activities for the next 3.5 months.
Ultimately, Eduardo will need to make thoughtful decisions about how he manages his money and balances his spending with his savings goal.

Suppose that the function H is defined, for all real numbers, as follows.
By evaluating the piece-wise function we will see:
h(-4) = 3h(-1) = 4h(1) = -4.5How to evaluate the piecewise function?
To evaluate the function, we just need to replace the variable x by the given numbers.
First, we want to get x = -4, notice that when x ≠ -1, we use the above equation.
Then to evaluate in x = -4 we use:
[tex]h(-4) = \frac{1}{2}*(-4)^2 - 5 = 3[/tex]
Then we want to evaluate in x = -1, so we need to use the below equation:
[tex]h(-1) = 4[/tex]
Finally, we want to evaluate in x = 1, so we use the above equation:
[tex]h(1) = \frac{1}{2}*1^2 - 5 = -4.5[/tex]

Find area of the triangle formed by x− and y−intercepts of the parabola y=4x^2−8x−5.
Answer:
7.5 unit square
Step-by-step explanation:
7.5 unit²
Step-by-step explanation:
Refer to attached
Find the y-intercept:
x = 0 ⇒ y = 4*0 - 8*0 - 5 = - 5
Find the x-intercepts:
y = 0 ⇒ 4x² - 8x - 5 = 0
4x² - 8x + 4 - 9 = 0
4(x - 1)² = 9
(x - 1)² = 9/4
x - 1 = 3/2 ⇒ x = 2.5
x - 1 = - 3/2 ⇒ x = - 0.5
We have vertices of the triangle at:
(- 0.5, 0), (2.5, 0) and (0, -5)
Base of the triangle is:
2.5 - (-0.5) = 3
Height of triangle:
0 - (-5) = 5
The area is:
A = 1/2bh
A = 1/2*3*5 = 7.5
Answer:
7.5 unit²
Step-by-step explanation:
find x and y intercepts
x = 0 ⇒ y = 4*0 - 8*0 - 5 = - 5
y = 0 ⇒ 4x² - 8x - 5 = 0
4x² - 8x + 4 - 9 = 0
4(x - 1)² = 9
(x - 1)² = 9/4
x - 1 = 3/2 ⇒ x = 2.5
x - 1 = - 3/2 ⇒ x = - 0.5
We have vertices of the triangle at:
(- 0.5, 0), (2.5, 0) and (0, -5)
Base of the triangle is:
2.5 - (-0.5) = 3
Height of triangle:
0 - (-5) = 5
The area is:

The number of pavers is the count of pavers that fit the garden
Jayden should buy 1 paver
The dimension of the garden is given as:
Length = 8ft
Width = 2ft
So, the area is calculated as:
Area = Length x Width
This gives
Area = 8ft x 2ft
Area = 16 square ft
The dimension of the paver is given as:
Length = 4ft
So, the area is calculated as:
Area = Length x Length
This gives
Area = 4ft x 4ft
Area = 16 square ft
The number of pavers is calculated by dividing the area of the garden by the area of the pavers.
So, we have:
[tex]\mathbf{Number = \frac{Garden}{Pavers}}[/tex]
[tex]\mathbf{Number = \frac{16ft^2}{16ft^2}}[/tex]
[tex]\mathbf{Number = 1}[/tex]
Hence, he should buy 1 paver
