Answer:
The inverse of x² +1 is:
[tex]\sqrt{x-1},\:-\sqrt{x-1}[/tex]
Step-by-step explanation:
Given
y = x² + 1, x>0
We know that A function g is the inverse of a function f if for y = f(x), x = g(y)
y = x² +1
Replace x with y
x = y² + 1
solve for y
y² = x - 1
Taking square root
[tex]y=\:\sqrt{x-1},-\sqrt{x-1}[/tex]
Thus, the inverse of x² +1 is:
[tex]\sqrt{x-1},\:-\sqrt{x-1}[/tex]

Two planes travel at a constant speed. Plane A travels 2,800 miles in 5 hours. Plane B travels 3,885 miles in 7 hours.
1. Which plane is faster?
Answer: First.
Step-by-step explanation:
Let's find the speed of the first airplane:
2800 ÷ 5 = 560 (miles per hour)
Let's find the speed of the second plane:
3885 ÷ 7 = 555 (miles per hour)
Thus, the first plane flies faster than the second.

The dimensions of a triangular prism are shown.
What is the surface area of the triangular prism?
A.20.5 square inches
B.29 square inches
C.32 square inches
D.14.5 square inches
Answer:
C
Step-by-step explanation:
To find surface area you find all the areas of the sides and add them up. We can start by setting up our equations.
A = L x W
For both the sides ——> 2(5 x 0.5) = 5
For both the triangle parts ——> bh/2 ———> (4 x 6)/2 times 2 = 24
For the bottom part ——> 6 x 0.5 = 3
Now to add everything up: 24 + 3 + 5 = 32
what is 3/4 multiplied by 16 (3/4 x 16)
4 goes into itself 1 and into 16 4 times then u just multiply the 3 x 4 which is equal to 12 ;)
Write a rule for the linear function in the table.
f(x) = 4 – x
f(x) = x + 4
f(x) = x – 4
f(x) = 4x
Answer: BRAINLY
f(x)=x-4 is the answer i believe
Answer :
The function is
Step-by-step explanation:
Given values in table :
x f(x)
3 -1
4 0
5 1
6 2
Here we see there is a difference of 4 in the values of x and f(x)
i.e. 3-(-1)=4
or 4-0=4
Similarly 5-1=4
6-2=4
So x-F(x)=4
Adding F(x) -4 both sides
x-F(x) +F(x) -4=4+F(x) -4
We have F(x)= x-4

Solve: 2x + 3y = 1
y = -23 +11
Answer:
x = 18.5
y = -12
Step-by-step explanation:
First, solve y:
y = -23 + 11
y = -12
Then, solve the main problem:
2x + 3y = 1
(Substitute y)
2x + -36 = 1
2x - 36 = 1
2x = 1 + 36 = 37
x = 37 / 2
x = 18.5
(Need help ASAP) In a research experiment, the population of a colony of bacteria doubles every hour. The population, f(x), of the colony after x hours can be modeled by the function f(x)=25 ⋅ 2x. What values for the domain are reasonable in the given context?
1. all real numbers
2. all real numbers greater than 0
3. all real numbers greater than or equal to 0
4. all real numbers greater than or equal to 25
Answer:
Step-by-step explanation:
The answer is 3
The reasonable domain is all real numbers greater than or equal to 0.
What is domain?The collection of all conceivable independent values that a function or relation may take is known as its domain.
Given:
In a research experiment,
the population of a colony of bacteria doubles every hour.
Here, we can use exponential growth function.
The population, f(x), of the colony after x hours can be modeled by the function f(x)=25 ⋅ 2ˣ.
The value of x can not be negative because it represents time.
The domain of the function is all achievable values.
So, the domain is all real numbers greater than or equal to 0
Therefore, the domain is all real numbers greater than or equal to 0.

One tract of land contains 25 acres. An adjoining tract of land is 1 square mile. The owners agreed to sell for $1,500 per acre. What was the total price of the 2 lots?
Answer:
$997,500
Step-by-step explanation:
Tract 1 = 25 acres
Tract 2 = 1 square mile
Cost of land per acre = $1500
Number of acres per square mile = 640 acres
Total number fo acres :
(Tract 1 + Tract 2)
(25 + 640) acres
= 665 acres
Total cost :
665 * $1500
= $997,500

A store makes 20% profit on the total price of all the items they sell.
let t represent the total price of all items sold in dollars, and let p represent the profit in dollars.
1) WRITE AN EQUATION TO REPRESENT THE RELATIONSHIP BETWEEN THESE VARIABLES:
Pls help! I don’t understand!! :/
Answer:
p=1/5t
Step-by-step explanation:
Since t is 100% of the items sold and p is 20% of that, the profit, p is 20% of t, or 1/5t.
Answer:
p = t(0.2)
Step-by-step explanation:
The profit is 20% of the total price. So if you multiply the total price by 0.2, you will get 20% of the total price which is the profit.
