Suzi starts her hike at 275 feet below sea level. When she reaches the end of the hike, she is still below sea level at −135 feet. What was the change in elevation from the beginning of Suzi's hike to the end of the hike?
Answer:
Have a nice day!
Step-by-step explanation:
Answer:
140
Step-by-step explanation:
Hi there!
This problem may seem tricky because of the negative sea level, os let’s set up an equation.
[tex]-275+x=-135[/tex] where x = the change in elevation.
Using orders of operations, add 275 to both sides and you will end with
x = 140
Her change in elevation is 140 feet.
I hope this helps!

Find the height of an equilateral triangle with side length 8.
Answer:
U need to just do
[tex] \sqrt{3 \div 4} a {}^{2} [/tex]
Answer:
4[tex]\sqrt{5}[/tex]
Step-by-step explanation:
The segment from a vertex to the side opposite is a perpendicular bisector.
The equilateral Δ is divided into 2 right triangles with legs 8 and 4
let height be h, then using Pythagoras' identity
h² = 4² + 8² = 16 + 64 = 80 ( take the square root of both sides )
h = [tex]\sqrt{80}[/tex] = 4[tex]\sqrt{5}[/tex] ← exact value

The equation y = 3.5x represents the total cost y in dollars of buying x pounds of cheddar cheese at Art’s Deli. The graph below shows the total cost y in dollars of buying x pounds of cheddar cheese at Jon’s Deli. What conclusion can you draw about the cost of cheddar cheese at these delis? Cheddar cheese costs $4 more per pound at Jon’s Deli than Art’s Deli. Cheddar cheese costs $0.50 more per pound at Jon’s Deli than Art’s Deli. Cheddar cheese costs $3.50 less per pound at Art’s Deli than Jon’s Deli. You pay the same price per pound for cheddar cheese at both delis.

f(x)=6x+4. Find the inverse of f(x).
Answer:
c
Step-by-step explanation:
f(x)=6x+4
y=6x+4
x=6y+4
6y=x-4
y=(x-4)/6
f^-1(x)=(x-4)/6
Answer is Option-C
How to find Inverse Function:
1. First, replace f(x) with y. This is done to make the rest of the process easier.
2. Replace every x with a y and replace every y with an x.
3. Solve the equation from Step 2 for y.
(Here), Given
f(x) = 6x + 4
Let's inverse function be y.
y = 6x + 4
First step is to switch the positions of x and y.
Inverse: x = 6y + 4
x - 4 = 6y
=> y = (1/6) * (x - 4)
Option-C

If your good at math plz help me
i think this is the answer, hope A(-3)=n-5
==================================================
Work Shown:
[tex]a_1 = -3 = \text{ first term}\\\\d = -5 = \text{ common difference}\\\\a_n = a_1 + d(n-1) = \text{ nth term}\\\\a_n = -3 + (-5)(n-1)\\\\a_n = -3 -5n + 5\\\\a_n = -5n + 2\\\\[/tex]
The common difference is due to us adding -5 to each term to get the next one. Example: -3+(-5) = -8, or -8+(-5) = -13.
--------------------
As a way to check if we have the correct nth term formula, plug in values of n to see if we get the correct sequence value
For instance, if n = 1, then
[tex]a_n = -5n+2\\\\a_1 = -5(1)+2\\\\a_1 = -5+2\\\\a_1 = -3\\\\[/tex]
Which matches with the first term given to us.
Or if n = 2, then,
[tex]a_n = -5n+2\\\\a_2 = -5(2)+2\\\\a_2 = -10+2\\\\a_2 = -8\\\\[/tex]
That matches the second term given to us. I'll let you check the others.
f(x) =2x squared - 5x - 3 g(x) = x squared + 6x - 1 what is h(x), if h(x) = g(x) - f(x)
Answer:
-2x^2 + x^2 +11x +2
Step-by-step explanation:
f(x) = 2x^2-5x -3
g(x) = x^2 + 6x -1
h(x) = g(x) - f(x)
x^2 + 6x -1 - 2x^2 +5x +3
-2x^2 + x^2 +11x +2

What are the interest cost and the total amount due on a six-month loan of $1,800 at 14.4 percent simple annual interest
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Principal (P)= $1,800
Number of periods (t)= 6 months
Monthly interest rate (r)= 0.144/12= 0.012
To calculate the interest to be paid and the total amount due, we need to use the following formula:
I= P*r*t
I= 1,800*6*0.012
I= $129.6
Total amount= $1,929.6

Answer:
Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.
Width = 55ft
Area = 4950 sq ft
Cost = $9900
Step-by-step explanation:
Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.
You have to convert the yards to ft to add it to the other ft.
1 Yard = 3 ft
So the width is 18 yards 1 ft = 54ft + 1ft = 55ft
To calculate the area is L x W
The length is 30 yards. Convert that to ft = 90ft
So 90 x 55 = 4950 sq ft
At $2 per sq ft, you multiply the 4950 sq ft by $2
2 x 4950 = $9900

What will be the return value of =SUM({10;15;20;25;30})?
Answer:
The return value is 100
Step-by-step explanation:
Given
[tex]=SUM({10;15;20;25;30})[/tex]
Required
Determine the return value
In Microsoft Office Excel, the sum of values is represented as:
[tex]=SUM({a_1;a_2;a_3;.....;a_n})[/tex]
This is interpreted as:
[tex]SUM= a_1;a_2+a_3+.....+a_n[/tex]
So, in the case of:
[tex]=SUM({10;15;20;25;30})[/tex]
The return value is:
[tex]Value= 10 + 15+ 20 + 25 + 30[/tex]
[tex]Value= 100[/tex]
Hence, the return value is 100
