Find the sum of 0.482 and 482.3152

ANSWER

D. x=55

EXPLANATION

The given radical equation is

[tex] \sqrt{x - 6} + 3 = 10[/tex]

Add -3 to both sides

[tex] \sqrt{x - 6} = 10 - 3[/tex]

[tex] \sqrt{x - 6} =7[/tex]

Square both sides.

[tex] { (\sqrt{x - 6})}^{2} = {7}^{2} [/tex]

[tex]x - 6 = 49[/tex]

Solve for x to get:

[tex]x = 49 + 6 = 55[/tex]

Answer:

C, [tex]4e^{i(7\pi/4)}[/tex]

Step-by-step explanation:

To remind you, Euler's formula gives a link between trigonometric and exponential functions in a very profound way:

[tex]e^{ix}=\cos{x}+i\sin{x}[/tex]

Given the complex number [tex]2\sqrt{2}-2i\sqrt{2}[/tex], we want to try to get it in the same form as the right side of Euler's formula. As things are, though, we're unable to, and the reason for that has to do with the fact that both the sine and cosine functions are bound between the values 1 and -1, and 2√2 and -2√2 both lie outside that range.

One thing we could try would be to factor out a 2 to reduce both of those terms, giving us the expression [tex]2(\sqrt{2}-i\sqrt{2})[/tex]

Still no good. √2 and -√2 are still greater than 1 and less than -1 respectively, so we'll have to reduce them a little more. With some clever thinking, you could factor out another 2, giving us the expression [tex]4\left(\frac{\sqrt{2}}{2} -i\frac{\sqrt{2}}{2}\right)[/tex] , and now we have something to work with.

Looking back at Euler's formula [tex]e^{ix}=\cos{x}+i\sin{x}[/tex], we can map our expression inside the parentheses to the one on the right side of the formula, giving us [tex]\cos{x}=\frac{\sqrt2}{2}[/tex] and [tex]\sin{x}=-\frac{\sqrt2}{2}[/tex], or equivalently:

[tex]\cos^{-1}{\frac{\sqrt2}{2} }=\sin^{-1}-\frac{\sqrt2}{2} =x[/tex]

At this point, we can look at the unit circle (attached) to see the angle satisfying these two values for sine and cosine is 7π/4, so [tex]x=\frac{7\pi}{4}[/tex], and we can finally replace our expression in parentheses with its exponential equivalent:

[tex]4\left(\frac{\sqrt2}{2}-i\frac{\sqrt2}{2}\right)=4e^{i(7\pi/4)}[/tex]

Which is c on the multiple choice section.

Answer:

Step-by-step explanation:

[tex]4y^2-37=27\qquad\text{add 37 to both sides}\\\\4y^2=64\qquad\text{divide both sides by 4}\\\\y^2=16\to y=\pm\sqrt{16}\\\\y=-4\ or\ y=4[/tex]

To solve for 'y' in the equation 4y^2 - 37 = 27, you isolate y^2, take the positive square root, and find that the positive value of y is y = 4.

To find the positive value of 'y' from the equation 4y^2 - 37 = 27, we first need to isolate y. Starting with 4y^2 - 37 = 27, add 37 to both sides to get 4y^2 = 64. Divide both sides by 4 to isolate y^2, leading to y^2 = 16. Finally, take the square root of both sides. Remember that the square root of a number gives both positive and negative solutions. However, because the question asks for the positive value, we ignore the negative root. Thus, the positive value of y is y = 4.

Hope this helped!

~Just a girl in love with Shawn Mendes

Answer: Option D

The inequality that represents the  situation is:

[tex]\frac{3}{5}(x-5)\leq 27[/tex]

following situation

Step-by-step explanation:

Suppose an unknown number X.

That number minus 5 is:

[tex]x-5[/tex]

Now, [tex]\frac{3}{5}[/tex] times the unknown number minus 5 is:

[tex]\frac{3}{5}(x-5)[/tex]

We know that all this expression is not greater than 27.

Then we use the symbol "less or equal than" ([tex]\leq[/tex]) to represent the situation

[tex]\frac{3}{5}(x-5)\leq 27[/tex]

If the diameter of a circle is 50 yards the radius must be 25 yards.

This is because the radius is always half the diameter of the circle. Since we know the diameter is 50 yards, half of 50 is 25 so the radius must be 25 yards.

Have a great day!

The radius of the circle is 25 yards.

A circle is a round shaped figure which has all its points in one plane and the distance between all the points on its circumference to the center of the circle is equal .

It is given that

Diameter of a circle is 50 yards.

Radius of a circle =  Diameter of circle / 2

Radius of the circle = 50/2 = 25 yards

Therefore the radius of the circle is 25 yards.

Answer: Whats the whole question?

Step-by-step explanation:

To find the measure of ∠ONK in rectangle MPKN with given conditions, it's determined through the congruency of triangles and properties of a rectangle that ∠ONK is 72°.

The question involves finding the measure of ∠ONK in rectangle MPKN, where the diagonals intersect at point O, and a line segment OA is an altitude of triangle MOP with m∠AOP = 18°. Given the properties of a rectangle, we know that its diagonals bisect each other and are equal in length. Therefore, triangles MOP and NOP are congruent.

Because OA is the altitude to hypotenuse MP of triangle MOP, it creates two right triangles, OAM and OAP. The angle ∠AOP is given as 18°, which means ∠MOA = 90° - 18° = 72° since triangle OAM is a right-angled triangle. Because the diagonals of the rectangle bisect each other at O, triangle ONP is congruent to triangle OMP, and hence ∠ONK (which is also ∠ONP) is equal to 72° as angle ∠ONP is supplementary to ∠MOA in rectangle MPKN.

Hence

log [tex]x^{4}[/tex] - log x³

= 4 log x - 3 log x

=log x

The value of logx⁴ - logx³ will be logx.

The exponent indicates the power to which a base number is raised to produce a given number called a logarithm.

In another word, a logarithm is a different way to denote any number.

If you want to write 1 in logarithm then it will be log(base).

The first method →

Given,

Answer:

The correct option is C.

Step-by-step explanation:

If a line passing through two point then the equation of line is

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

From the given graph it is clear that the line of best fit passing through the points (0,0) and (14,45). So, the equation of line of best fit is

[tex]y-0=\frac{45-0}{14-0}(x-0)[/tex]

[tex]y=\frac{45}{14}x[/tex]

The equation of line of best fit is [tex]y=\frac{45}{14}x[/tex], therefore the correct option is C.

y = 218.2. The lenght of side y by  trigonometry is 218.2.

In order to solve this problem we are going to use the angles and sides of a right triangle and its relation by expressions that we call trigonometric ratios.

In the image we can see that the lenght of the opposite leg is 141 , we do not know the lenght of the adjacent leg y and the hypotenuse x. The key to solve this problem is to use trigonometric ratios and the equation tan θ = sin θ/cos θ = opposite leg/adyacent leg = 141/y

Clear for y for the equation tan θ = sin θ/cos θ = 141/y, we obtain:

y = arctan θ (141)

y = arctan (43°)(141) = 218.2

Answer: The answer is 15 * 14

Step-by-step explanation:

You start with 15 people to choose from to select a president, so you have 15. After removing one person 15-1,=14 you have fourteen people to choose from, to select a vice president. This gives you 15*14.

The expression that can be used to represent the number of ways that a president and a vice-president can be chosen out of a group of 15 people is 15×14 or ¹⁵P₂.

Permutation helps us to know the number of ways an object can be arranged in a particular manner. A permutation is denoted by 'P'.

[tex]^nP_r = \dfrac{n!}{(n-r)!}[/tex]

where,

n is the number of choices available,

r is the choices to be made.

The number of people that are available for the post of the president is 15, while the number of people that are available for the post of vice-president after the president is selected is 14. Therefore,

Number of ways in which president and vice-president can be selected

= ¹⁵P₂

= 15 × 14

Hence, the expression that can be used to represent the number of ways that a president and a vice-president can be chosen out of a group of 15 people is 15×14 or ¹⁵P₂.

To subtract the given expressions, first, simplify each expression separately by combining like terms. Then subtract the second expression from the first expression by distributing a negative sign and adding it to the first expression.

To subtract the given expressions, (2x^3+7x^2-4) - (2x^2+4x-10), we need to simplify each expression separately and then subtract them. First, combine like terms within each expression. Then, subtract the terms of the second expression from the first expression. This can be done by distributing a negative sign to each term in the second expression and then adding it to the first expression.

So, (2x^3+7x^2-4) - (2x^2+4x-10) = 2x^3+7x^2-4 - 2x^2-4x+10.

Combining like terms, we get 2x^3+(7x^2-2x^2)+(-4-4x)+(10). Simplifying further, we have 2x^3 + 5x^2 - 4x + 6. Therefore, the result of the subtraction is 2x^3 + 5x^2 - 4x + 6.
