No, 39 is not a perfect square number because it can't be equal to square of any integer.

An integer that can be expressed as the square of another integer is called a perfect square. In other words, a perfect square is the square of an integer such as 1 = 1², 4 = 2², 9 = 3², 16= 4², , forward. Thus , perfect square formula is written as N = x², where x is any integer. I have the number 39 and I need to check if it is a perfect square. For this we can take the square root of this number. A number is a perfect square if its square root is an integer. So, √39 = √3×13

= 6.2449 ( using calculator)

Which is not an integer, so it is not a perfect square.

The value of √N is 3.16159

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².

Given here: A quadrilateral WXYZ with ∠Z=75 and ∠X=105

Let P be a point on ZW such that ZP=x and WP=4-x, then we form a right-angled triangle ΔZPY with tan 15°=x/PY

∴ PY=x/tan 15

       =3.732x

Now using Pythagoras' theorem we get ZY as

 [tex]\sqrt{13.927x^2+x^2} \\=\sqrt{14.92x^2}\\ =3.862641x[/tex]

Now let's connect the diagonal ZX we get the right triangle ZWX

Thus using Pythagoras' theorem we get

ZX=[tex]\sqrt{4^2+4^2}[/tex]

    =4√2

Again let Q be an extension such that YQ=4-x & ∠YXQ=75°

Thus Sin 75=4-x/√N

            √N=4-x/0.965923

squaring both sides we get N=(4-x)²/0.9330127........(1

Now using the Pythagoras theorem in ΔZYX we get

√N=

[tex]\sqrt{ZX^2-ZY^2} \\=\sqrt{32-14.92x^2} \\[/tex]

⇒N=32-14.92x²..,.......2)

Thus equation two values of N we get

(4-x)²/0.9330127=32-14.92x²

16-8x+x²=29.8564-13.920549x²

14.921x²-8x-13.856=0

Thus using the quadratic formula we get the value of x as

x= 8±29.85 /29.84

x=1.2684  (∵ Distance cannot be negative)

∴ Value of N=32-14.92×1.2684

                    N=13.075

                   √N=3.6159

Answer: -7/3

Step-by-step explanation:

y/3 - 8 = -15

y/3 = -7

y = -7/3

Answer:

A. See attached graph

B. [tex]\boxed{y = 0.12x^2+ 12}[/tex]

C. [tex]\boxed{160\;square\;feet}[/tex]

Step-by-step explanation:

Consider the figure which shows the cross-sectional view of the parabolic tunnel as viewed from the entrance

A. See attached graph

B. The parabola is drawn with the y-axis as the axis of symmetry.

The x-intercepts are at (-10, 0) and (10, 0)

The vertex is at (0, 12)

The vertex form equation for a parabola is
y = a(x - h)² + k

where (h, k) is the vertex - the (x, y) coordinates of the vertex

Here h = 0, k = 12

So the parabola equation is:

y = a(x - 0)² + 12

y = ax² + 12

To find a, plug in one of the x-intercepts, say (10, 0)

We get

0 = a(10)² + 12

0 = 100a + 12

100a = -12

a = -12/100 = -0.12

Therefore the equation of the parabola is
[tex]\boxed{y = 0.12x^2+ 12}[/tex]

C. The cross-sectional area is given by the formula:

D.  To find the area of the parabola between x = -10 and x = 10 which forms the base of the parabola, you can use the formula
[tex]A = \dfrac{2}{3}bh\\\\[/tex]

where b is the base length and h is the height

Using the values for b = 20 and h = 12 we get

[tex]A = \dfrac{2}{3}\cdot 20 \cdot 12 = 160 \textrm { square feet}[/tex]

Using the definite integral, let's find the area between x = -10 and x = 10

I am not going through every step but leading you to the final answer

[tex]\int _{-10}^{10}\left(\:-0.12x^{2\:}+\:12\right)dx\\\\\\\textrm{We have}\\\\0.12\cdot \int _{-10}^{10}x^2dx=0.12\left[\frac{x^3}{3}\right]_{-10}^{10}\\\\[/tex]

[tex]=0.04\left[x^3\right]_{-10}^{10}\\\\= 80\\\\[/tex]

Therefore
[tex]-0.12\cdot \int _{-10}^{10}x^2dx = -80[/tex]

[tex]\int _{-10}^{10}12dx = \left[12x\right]_{-10}^{10} = 240[/tex]

So total area = -80 + 240 = 160 square feet

Ans: Cross sectional area = [tex]\boxed{160\;square\;feet}[/tex]

Answer:

m = 24

Step-by-step explanation:

To solve the equation m/3-7 =1, we can start by isolating m on one side of the equation. To do this, we will add 7 to both sides of the equation:

m/3 - 7 + 7 = 1 + 7

m/3 = 8

The next step is to multiply both sides of the equation by 3 to get rid of the fraction:

m/3 * 3 = 8*3

m = 24

So the solution to the equation is m=24

Answer:

x = 100

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. In this case, you will add 10 to both sides of the equation, to isolate x:

x - 10 = 90

x - 10 (+10) = 90 (+10)

x = 90 + 10

x = 100

The difference between the smallest 6-digit number with five different digits and the greatest 5-digit number with four different digits is 358.

The aim is to find the largest 5-digit number with four different digits and the smallest 6-digit number with five different digits, and then we need to find how many numbers are between these two values.

Let's start by finding the smallest 6-digit number with five different digits.

We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit, 1; therefore, it can be used in the highest place value.

Thus, we can create the required 6-digit smallest number with 0 and 1.

Hence, the smallest 6-digit number is 100234.

Now, we will discover the largest 5-digit number.

As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 5-digit number with the digit 9.

Thus, the largest 5-digit number is 99876.

Now, calculate the difference between these two numbers.

So, we can determine the difference between the smallest 6-digit number and the largest 5-digit number by subtracting the smallest from the largest.

Thus, we get,

⇒100234 - 99876

⇒358

Hence, 358 is the difference between the smallest 6-digit with five different digits and the largest 5-digit number with four different digits.

Step-by-step explanation:

Salma's savings can be represented by the equation S = 35 + 8t, where t is the number of weeks after the beginning of the year.

Henry's savings can be represented by the equation H = 95 + 5t

To determine the number of weeks after the beginning of the year until Salma and Henry have the same amount of money saved, we need to set the two equations equal to each other and solve for t:

35 + 8t = 95 + 5t

3t = 60

t = 20

So it would take Salma and Henry 20 weeks after the beginning of the year to have the same amount of money saved.

Exponential functions and logarithmic functions are related but inverse of each other.

Exponential functions are used to model growth and decay, while logarithmic functions are used to model inverse growth and decay.

An exponential function is a function in the form of f(x) = b^x, where b is a positive constant called the base. The variable x is the exponent, and the value of the function is the result of raising the base to the power of x. For example, f(x) = 2^x is an exponential function. The graph of an exponential function is always increasing and never touches or crosses the x-axis, as long as b>1.

On the other hand, a logarithmic function is a function in the form of f(x) = log_b(x) or f(x) = ln(x), where b is a positive constant called the base (or e for natural logarithm) and x is the argument of the logarithm. The value of the function is the exponent to which the base must be raised to produce x. For example, f(x) = log2(x) is a logarithmic function. The graph of a logarithmic function is always decreasing and asymptotic to the x-axis.
