Answer:
n = 25
Step-by-step explanation:
The smallest perfect square larger than 144 = 12² is 169 = 13². As it happens, the difference of these squares is 25, a number divisible by 5.
So n=25 will make all of the expressions have values that are natural numbers.
_____
n = 0 would make all of them integers, but 0/5 = 0 is not a natural number.

A = [tex]\frac{1}{2}[/tex]h(B + b) Solve for B.
(area of a trapezoid)
A = 1/2h(B+b)
Multiply both sides by 2:
2A = h(B+b)
Divide both sides by h:
2A/h = (B+b)
Subtract b from both sides:
2A/h - b = B
Switch the equation so B is on the left side:
B = 2A/h - b
Step-by-step explanation:
[tex]a = \frac{1}{2} h( \beta + b) \\ 2a = h( \beta + b) \\ \frac{2a}{h} = \beta + b \\ \frac{2a}{h} - b = \beta \\ thank \: you[/tex]

Answer:
D cos (1/2 x )
Step-by-step explanation:
y = cos (x/2)
because from the graph x = 2pie
= cos pie = -1
The function whose graph is given by; cos (1/2 x )
What is graph?A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For example, if the graph of a function is rising upwards after a certain value of x, the function must be having increasingly output for inputs greater than that value of x.
If the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
The function that we are given graphed has the point (0,1), this means whichever function f(x) it represents f(0) = 1.
Now, only the cosine function has the property that cos(π) = -1, thus
y = cos (x/2)
because from the graph x = 2π
The function whose graph is given by; cos (1/2 x )

the object is dropped from the height of 100 m.reached to ground in 10 seconds. find the acceleration of falling object.
======================================================
Work Shown:
The given values are
vi = 0 = initial velocity (meters per second)d = 100 = distance traveled (in meters)t = 10 = time in secondsPlug those items into the equation below. Solve for 'a'
d = vi*t + (1/2)*a*t^2
100 = 0*10 + (1/2)*a*10^2
100 = 0 + 50a
100 = 50a
50a = 100
a = 100/50
a = 2
The object is falling with an acceleration of 2 m/s^2
This is far below the acceleration of gravity on earth (which is roughly 9.81 m/s^2), so perhaps this object is being dropped on a smaller planet.

A composite function is the combination of two or more functions to create another function. The value of (f o g)(1) is 126
Given that:
[tex]f(x) = 2x^2 + 4x + 15[/tex]
[tex]g(x) = 2x^2 + 4x[/tex]
[tex](f\ o\ g)(x)[/tex] is calculated as:
[tex](f\ o\ g)(x) = f(x) \times g(x)[/tex]
So, we have:
[tex](f\ o\ g)(x) = (2x^2 + 4x + 15) \times (2x^2 + 4x)[/tex]
Substitute 1 for x
[tex](f\ o\ g)(1) = (2 \times 1^2 + 4 \times 1 + 15) \times (2 \times 1^2 + 4 \times 1)[/tex]
[tex](f\ o\ g)(1) = (21) \times (6)[/tex]
[tex](f\ o\ g)(1) = 126[/tex]
Hence, the value of (f o g)(1) is 126

The value of 0.16 x 42.1 x 8.73 after multiplying is 58.80528.
Given,
(0.16)(42.1)(8.73)
We need to multiply the decimal numbers.
How do we multiply decimal numbers?When we multiply decimal numbers the decimal point should be placed after the number of counts from the right side.
The number of counts is the sum of the counts of numbers before the decimal point of each decimal number from the right side.
Example:
1.23 x 134.5
Here,
In 1.23 there are two numbers before the decimal point.
In 134.5 there is one number before the decimal point.
So the count = 2 + 1 = 3
So,
There should be three numbers after the decimal point in 1.23. x 134.5.
1.23. x 134.5 = 165.435
Find 0.16 x 42.1 x 8.73 by multiplying.
We see that,
There are two numbers after the decimal point in 0.16
There are one numbers after the decimal point in 42.1
There are two numbers after the decimal point in 8.73
So,
2 + 1 + 2 = 5 numbers
There should be 5 numbers after the decimal point in 0.16 x 42.1 x 8.73
Now,
0.16 x 42.1 x 8.73 = 58.80528.
Thus the value of 0.16 x 42.1 x 8.73 is 58.80528.
