Answer:

[tex]\frac{2+\sqrt{3} }{4}[/tex]

Step-by-step explanation:

We can use the identity [tex]Cos^2(x)=\frac{1}{2}+\frac{1}{2}Cos(2x)[/tex] to write it as:

[tex]Cos^2(\frac{\pi}{12})=\frac{1}{2}+\frac{1}{2}Cos(2(\frac{\pi}{12}))\\=\frac{1}{2}+\frac{1}{2}Cos(\frac{\pi}{6})\\=\frac{1}{2}+\frac{1}{2}(\frac{\sqrt{3} }{2})\\=\frac{1}{2}+\frac{\sqrt{3} }{4}\\=\frac{2+\sqrt{3} }{4}[/tex]

Note: The value of [tex]Cos(\frac{\pi}{6})[/tex]  is  [tex]\frac{\sqrt{3} }{2}[/tex]

The answer is the 2nd one, [tex]\frac{2+\sqrt{3} }{4}[/tex]

Answer:

Step-by-step explanation:

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

b - y-intercept → (0, b)

We have the points J(-4, -5) and K(-6, 3).

The points J, K and y-intercept A(0, b) are collinear. Therefore the slope of JA and KA are the same.

We have the equation:

[tex]\dfrac{b-(-5)}{0-(-4)}=\dfrac{b-3}{0-(-6)}\\\\\dfrac{b+5}{4}=\dfrac{b-3}{6}\qquad\text{cross multiply}\\\\6(b+5)=4(b-3)\qquad\text{use the distributive property}\\\\6b+30=4b-12\qquad\text{subtract 30 from both sides}\\\\6b=4b-42\qquad\text{subtract 4b from both sides}\\\\2b=-42\qquad\text{divide both sides by 2}\\\\b=-21[/tex]

Answer:

y = 40

Step-by-step explanation:

Isolate the variable (y). Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides.

y - 4 = 36

y - 4 (+4) = 36 (+4)

y = 36 + 4

y = 40

Check. Substitute 40 for y.

Plug in 40 for y.

y - 4 = 36

(40) - 4 = 36

36 = 36 (True).

Answer:

6³/₁₀

Step-by-step explanation:

Number of bits = Total amount/Size of each bit

                         = (4⅕)/(⅔)

Convert the mixed number to an improper fraction

No. = (²¹/₅)/(⅔)

Invert the denominator and change division to multiplication

No. = ²¹/₅ × ³/₂

Multiply numerators and denominators.

No. = ⁶³/₁₀

Convert the improper fraction to a mixed number.

No. = 6³/₁₀

It takes 6³/₁₀ ⅔s to make up 4⅕.

That decimal would be -.875

Hey there!

In order to find the decimal divide the numerator (top number) from the denominator (bottom number)

~ -7 ÷ 8 = 0.875 (as a decimal)

~ Thus your answer will most likely be, -0.875

Good luck on your assignment and enjoy your day!

Answer:

Step-by-step explanation:

The standard form of an equation of a line:

[tex]Ax+By=C[/tex]

We have the equation in point-slope form:

[tex]y+7=-\dfrac{2}{5}(x-10)[/tex]

Convert it to the standard form:

[tex]y+7=-\dfrac{2}{5}(x-10)[/tex]     multiply both sides by 5

[tex]5y+35=-2(x-10)[/tex]         use the distributive property a(b + c) = ab + ac

[tex]5y+35=(-2)(x)+(-2)(-10)[/tex]

[tex]5y+35=-2x+20[/tex]          subtract 35 from both sides

[tex]5y=-2x-15[/tex]            add 2x to both sides

[tex]2x+5y=-15[/tex]

in degrees the answer is 30° since a full rotation is 360°, divide by 12 and 1/12 of a full rotation is 30°

1/12 of a full rotation in mathematics refers to an angle of 30 degrees. This is calculated by dividing the full rotation (360 degrees) by 12. For example, each hour on a clock represents 1/12 of a full rotation.

In Mathematics, a full rotation is defined as 360 degrees. Therefore, to find 1/12 of a full rotation, you would divide 360 by 12. This results in 30 degrees. Hence, 1/12 of a full rotation refers to an angle of 30 degrees in a circular motion. This concept is often applied in geometry and other mathematical applications. For instance, imagining a clock, where each hour signifies 1/12 of a full rotation. The difference in the angle from 12 to 1 on the clock is therefore 30 degrees.

Answer:

Step-by-step explanation  

The first step you have to get it into this form

a[tex]x^{2}[/tex] + bx + c

So that would be

3x[tex]x^{2}[/tex] + 1x + c

we do not know what c is

we have to get x by it self from 3x[tex]x^{2}[/tex] so first you have to square it now we are at 9x

    9x divided by 9 that would leave us with x

so our finished product is x + 1x + c  

we have to get x by itself from 1x so we do exactly what we just did 1x divided by 1x would leave us with x

x + x=[tex]x^{2}[/tex] + x

[tex]x^{2}[/tex] + c is the finished product which is your answer

Answer:

[tex]V = 25d ^ 3 + 275d ^ 2 + 250d[/tex]

Step-by-step explanation:

If the pool has a rectangular shape then its volume can be written as:

V = Width * Length * Depth

Let's call:

w = width

l = length

d = depth.

So we know from the statement of the problem that:

[tex]d = d[/tex]

[tex]w = 5 + 5d[/tex]              (5 feet more than 5 times the depth)

[tex]l = 50 + 5d[/tex]              (50 feet more than 5 times the depth)

Then, the volume can be written according to the depth as:

[tex]V = d(5 + 5d)(50 + 5d)[/tex]

[tex]V = d[250 + 25d + 250d + 25d ^ 2][/tex]

[tex]V = 25d ^ 3 + 275d ^ 2 + 250d[/tex]

The volume of the swimming pool is represented by the expression V = (5d + 50)(5d + 5)(d), where d is the depth of the pool.

The student is asked to find a simplified expression to represent the volume of the swimming pool, with the pool's depth given as d feet. To calculate the volume, we need to find the dimensions for the width and length of the pool. The width is described as 5 feet greater than 5 times its depth, which translates to

5d + 5 feet.

The length is 50 feet greater than 5 times its depth, so it will be

5d + 50 feet. The volume (V) of a rectangular solid is given by the product of its length (L), width (W), and depth (D), so the volume of this swimming pool is

V = LWD = (5d + 50)(5d + 5)(d).

Answer:

[tex]y - 3 = \frac{1}{4}(x+2)[/tex] or choose any line with slope 1/4

Step-by-step explanation:

The slope of this line is -4. The slope of the line perpendicular to this line will be the negative reciprocal or 1/4.

Write the equation using the slope m=1/4 and the point slope form.

[tex]y-y_1=m(x-x_1)\\y-3=\frac{1}{4}(x+2)[/tex]

This is the equation of the line that is perpendicular and passes through the same point (-2,3) as the equation listed.

Answer:

[tex]y=\frac{1}{4} x+c[/tex]   where [tex]c[/tex] can be any number.

Step-by-step explanation:

First we need to clear for y:

[tex]y-3 =-4(x+2)\\y=-4(x+2)+3\\y=-4x-8+3\\y=-4x-5[/tex]

and now we have an equation of the form:

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept.

in this case [tex]m=-4[/tex] and [tex]b=-5[/tex]

to find and equation perpendicular to this line, the following must be true:[tex]m*m_{1}=-1[/tex]

where m is the slope of the original line that i just mentioned, and [tex]m_{1}[/tex] is the slope of the new line. Substituting [tex]m=-4[/tex]

[tex]-4*m_{1}=-1[/tex]

clearing for [tex]m_{1}[/tex]

[tex]m_{1}=\frac{-1}{-4} \\m_{1}=\frac{1}{4}[/tex]

thus, the new perpendicular line must have the form:

[tex]y=m_{1}x+c\\y=\frac{1}{4}x+c[/tex]

where the y-intecept [tex]c[/tex] can be any number, some examples are:

[tex]y=\frac{1}{4}x+3\\y=\frac{1}{4}x-8[/tex]

and so on, the important thing to be a perpendicular line is that the slopes are related to the equation [tex]m*m_{1}=-1[/tex].

Final answer:

To surround a circular garden with a 150-ft radius every 3 inches with flowers, calculate the garden's circumference using the formula C = 2πr, convert it to inches and divide by the spacing. You'd need approximately 3,768 flowers.

Explanation:

To calculate the number of flowers needed to surround a circular garden with a 150-ft radius spaced every 3 inches, you have to find the circumference of the garden and then determine how many 3-inch spaces fit along that circumference.

First, find the circumference (C) of the garden using the formula C = 2πr, where π (pi) is approximately 3.14 and r is the radius. In this case:

Convert 942 ft into inches because the spacing is in inches:

Now, divide the circumference in inches by the spacing to get the number of flowers:

Therefore, you would need 3,768 flowers to surround the garden spaced every 3 inches.

We can simplify this as:

[tex]\sqrt{169*x^5} \\=\sqrt{169} \sqrt{x^5}[/tex]

Now we can use the property of radicals,  [tex]\sqrt[n]{x^a} =x^{\frac{a}{n}}[/tex]  , to write as:

[tex]\sqrt{169} \sqrt{x^5} \\13*x^{\frac{5}{2}}[/tex]

D is right answer.

Answer:

d. [tex]13x^{\frac{5}{2}}[/tex]

Step-by-step explanation:

The given expression is

[tex]\sqrt{169x^5}[/tex]

We can rewrite this as

[tex]\sqrt{169}\times \sqrt{x^5}[/tex]

We rewrite as a rational exponent to obtain;

[tex](13^2)^{\frac{1}{2}}\times (x^5)^{\frac{1}{2}}[/tex]

Recall that;

[tex](a^m)^n=a^{mn}[/tex]

[tex]13^{(2\times \frac{1}{2})}\times (x)^{5\times \frac{1}{2}}[/tex]

[tex]13^1 (x)^{\frac{5}{2}}[/tex]

The correct choice is D

[tex]13x^{\frac{5}{2}}[/tex]
