given the following table with selected values of f(x) and g(x) evaluate f(g(1))
The value of f(g(1) from the table of functions is given as 1.
What is Functions ?Each element of X receives precisely one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.
A function is a procedure or a relation that links each element of a non-empty set A, at least one element of another non-empty set B, to another element of the first non-empty set A. In mathematics, a relation f between two sets, A and B, is referred to as the function's domain and co-domain.
A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a connection between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input.
when x = 1
g(x) = 3
or f(g(1) = f(3) = 1
The value of f(g(1) from the table of functions is given as 1.

The short leg of a right triangle is 10 meters and the acute angles measure 25° and 65°. find the measures of the longer leg of the right
triangle.
When the short leg of a right triangle is 10 meters long and the sharp angles are present, the right triangle's longer leg has a measurement of 21.45 meters.
what is right angle ?Right angles are created when two straight lines cross at a 90° angle or are perpendicular to one another at the intersection. The sign stands for a right angle. Different right angle formations can be seen in the above image. The proper angles can be found in shapes. Right triangles are triangles with one of the internal angles at a right angle of 90 degrees. Since a triangle's three interior angles sum up to 180 degrees, a right triangle's three interior angles must always add up to 90 degrees since one of them is always 90 degrees.
given
x / sin 65° = 10 / sin 25°
x = 10 sin 65°/ sin 25°
x = 21 .45 meters
as law of sine
a / sinA = b / sinB = c / sinC
When the short leg of a right triangle is 10 meters long and the sharp angles are present, the right triangle's longer leg has a measurement of 21.45 meters.

3. Students from 4 classes at Franklin Elementary School are going on a field trip to the theater. Each
class has 30 students. There will also be 6 teachers and 14 parents on the trip. There are 20 seats in
each row at the theater. How many rows should be reserved for the field trip?
A 2
B 7
C 74
D 140
Answer:
B) 7
Step-by-step explanation:
Given information:
Number of classes = 4Number of students in each case = 30Number of teachers = 6Number of parents = 14Number of seats per row = 20If there are 30 students in each class, and there are 4 classes, the total number of students is:
[tex]\begin{aligned}\implies \textsf{Total students}&=\textsf{Students per class} \times \textsf{Number of classes}\\&=\sf 30 \times 4\\&=\sf 120\end{aligned}[/tex]
Therefore, the total number of people going on the trip is:
[tex]\begin{aligned}\implies \textsf{Total number of people}&=\sf Students+Teachers+Parents\\&=\sf 120+6+14\\&=\sf 140\end{aligned}[/tex]
As there are 20 seats in each row at the theater, to calculate how many rows should be reserved for the trip, divide the total number of people by the number of seats per row:
[tex]\begin{aligned}\implies \textsf{Rows to reserve}&=\sf \dfrac{\sf Total\;people}{\sf Seats\;per\;row}\\\\&=\sf\dfrac{140}{20}\\\\&=\sf 7\end{aligned}[/tex]
Therefore, 7 rows should be reserved for the field trip.

The length in feet of the longest part of the garden would be = 6ft
What is a garden?A garden is defined as an area that is prepared and set aside for the purpose of growing various flowers, shrubs and grasses.
The area of the given triangle = 54in²
The perimeter of the given triangle = 36 in.
Using the formula for area of a triangle ;
Area = ½ base(b) ×height(h)
where base = 9 in
54 = 1/2 × 9 × h
Make h the subject of formula;
h = 54×2/9
h = 108/9
h = 12
But the perimeter = sum of the whole sides of the triangle
perimeter = 36
side a = 9
side b = 12
side c = X
that is , 36 = 9+12+X
make X the subject of formula;
X = 36-21
X = 15in
Therefore, 15 in when converted to feet;
2 ft = 5 in
X ft = 15 in
