The Square root function is written in the form of f(x) = √x .
The Square Root function is defined as the function in which the parent function is written in the form of f(x) = √x .
and the inverse of the Square root function is square function , f(x) = x² .
The Domain and range of the root function is [0 , ∞) .
which means the range is the set of all positive real numbers and
hence in the square root function, result is always positive.
Some Examples of Root Functions are , √2 , √3 , √8 etc. .

It takes you 3 hours to drive to a concert 135 miles away. You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads. Write a system of linear equations that represents this equation. Use x to represent the number of hours driving on a highway and y to represent the number of hours driving on other roads.
Answer:
x + y = 3 (1)
55x + 40y = 135 (2)
Step-by-step explanation:
Since x to represent the number of hours driving on a highway and y to represent the number of hours driving on other roads and the total time for driving is 3 hours,
x + y = 3 (1)
Also, You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads, the distance moved on highways is 55x and the distance moved on the rest of the roads is 40y (since distance = speed × time).
Since the total distance moved is 135 miles, we have
55x + 40y = 135 (2)
So, the system of linear equations that represent the situation is
x + y = 3 (1)
55x + 40y = 135 (2)

An architect has designed a new hotel shaped like a giant rectangular pyramid. The base of the model for this hotel measures 20 inches by 30 inches, and is 25 in. tall. What is the volume of the pyramid?
Answer:
Volume of pyramid = 5000 cubic inches.
Step-by-step explanation:
Given the following data;
Length = 20 inches
Width = 30 inches
Height = 25 inches
To find the volume of pyramid;
Mathematically, the volume of a pyramid is given by the formula;
[tex] Volume = \frac {1}{3} * base \; area * height [/tex]
First of all, we would determine the base area;
Base area = length * width
Base area = 20 * 30
Base area = 600 in²
Substituting into the formula, we have;
[tex] Volume = \frac {1}{3} * 600 * 25 [/tex]
[tex] Volume = 200 * 25 [/tex]
Volume of pyramid = 5000 cubic inches.
1. Jemima wants to make chocolate chip walnut brownles. Chocolate chips come in a 12oz bag that costs $3. Walnuts
come in a 4oz bag that costs $2. If Jemima needs three pounds of chocolate chips and walnuts combined, and has $15
to spend, how many bags of each can she buy?
Answer:
4 bags of chocolate chips and 1 bag of walnuts.
Step-by-step explanation:
Find how many ounces are in 3 pounds:
16 oz = 1 lb
16 oz × 3 = 3 lbs
48 oz = 3 lbs
Variable x = number of chocolate chips
Variable y = number of walnuts
4x + 1y = 15
Keep in mind it must equal up to 48 oz and be $15 or under.
4 bags × 12 oz = 48 oz
1 bag × 4 oz = 4 oz
48 oz + 4 oz = 52 oz > 48 oz
4 bags × $3 = $12
1 bag × $2 = $2
$12 + $2 = $14 < $15
Both requirements have been met.

Moosa's sister is six years younger than 3 times his age. The sum of their ages is 30. How old is Moosa?
Suppose Moosa is ( x ) years old ,
Thus Moosa's sister is ( 3x - 6 ) years old .
The sum of their ages is 30 :
( x ) + ( 3x - 6 ) = 30 ==》 4x - 6 = 30
==》 4x = 36
==》 x = 9
So Moosa is 9 years old .

If y varies directly with x and y = 84 when x = 12, find y when x = 11.
Answer:
y= 77
Step-by-step explanation:
Write down the equation for direct proportion.
y= kx, where k is a constant.
Find the value of k.
When x= 12, y= 84,
84= k(12)
12k= 84
k= 84 ÷12
k= 7
Substitute the value of k into the equation.
y= 7x
When x=11,
y= 7(11)
y= 77

On day 3, he will hike directly from Point C to Point A.
We have to determine the distance Jeremy will need to travel between Point C and Point A.
What is the distance formula?
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]
d = distance
(x_1, y_1) = coordinates of the first point
(x_2, y_2) = coordinates of the second point
(4,9)=(x_1,y_1)
(-4,-9)=(x_2,y_2)
[tex]d = \sqrt{(-4 - 4)^2 + (-9-9)^2}\\d=\sqrt{(8)^2+(18)^2} \\d=2\sqrt{97}\\ d=19.69[/tex]
