Answer:

n = 1

Step-by-step explanation:

This equation is just basic alegebra.  First, combine like terms to get

9 - n = 8n.  (Because 3 - 3 = 0, and -4n + 3n = -n.)  Now the equation is much simpiler;  add n to both sides to get 9 = 9n.  Divide 9 by both sides to get that n = 1.  

You can check your answer by plugging 1 in for n.  

9 - 4(1) + 3(1) = 8(1) + 3 - 3

9 - 4 + 3 = 8 + 3 - 3

5 + 3 = 11 - 3

8 = 8

Therefore, n is proven to equal 1.  

Hope this is helpful :)

Answer:

x = 14

y = 14√2

Step-by-step explanation:

This is an isosceles triangle so x = 14

This triangle is a special right triangle with angle measures of 45 ° 45° and 90°

and side lengths are represented by a, a, and a√2 since we know the value of x is = 14 then y = 14√2

Answer:

(x+10)² + (y-8)² = 41

Step-by-step explanation:

First, we find the length of the diameter.

from distance formula, d = SQR ROOT OF [(-14+6)² + (13-3)²]

diameter = SQR ROOT OF [8² + 10²] = √164 = √4√41 = 2√41

*****    so the radius is half that, r =√41

The center of the circle is at the midpoint of the diamater.

x = (1/2)(-6 + -14) = (1/2)(-20) = -10

y = (1/2)(3 + 13) = (1/2)(16) = 8

center (h,k) = (-10,8)

circle equation: (x-h)² + (y-k)² = r²

(x- -10)² + (y - 8)² = (√41)²

(x+10)² + (y-8)² = 41

Sorry it took a while.

Answer:

5

Step-by-step explanation:

square root q = 6 meaning that q is 36, when q/p = 4 you can plug in36 for q and divide by 4 getting 9 and now you have q = 36 and p = 9, and p+9=45 and 45/5=9 meaning that s is 5.

Answer:

temp after 13 minutes is 330 degrees

Step-by-step explanation:

70+(20/13)=260+70=330

Answer:

330 Degrees

Step-by-step explanation:

First, you will want to multiply 20 timesthe time 13. You would get 260, but don't forget about the initial temperaure of 70 so add that, and you will get 330 degrees. I hope this helps :)

Answer:

12x^227xy^2 - 20xy4y^3

Step-by-step explanation:

(-3x5y) (-4x9y^2)

first : -3x (-4x9y^2) = 12x^227xy^2

second: 5y(-4x9y^2) = -20xy45y^3

then we add them (12x^227xy^2) + ( -20xy45y^3)

= 12x^227xy^2 - 20xy45y^3

He would need to get a minimum of 28 questions correct.

Step-by-step explanation:

92% of 30 is 27.6 but you cant really get .6 of a question right, so you would need to round. Which makes it 28.

Answer:

264 sq. in.

Step-by-step explanation:

The easiest way to find the lateral surface area is to multiply the perimeter of the base times the height.

In your case the perimeter of the base is 2(8) + 2(3) = 16 + 6 = 22

The height is 12, so multiply 12 times 22 = 264 sq. in.

Table (C) represents the same slope -3 as the line y = 2 - 3x.

The value of the steepness or the direction of a line in a coordinate plane is known as the slope of a line, often known as the gradient. Given the equation of a line or the coordinates of points situated on the straight line, slope can be determined using a variety of techniques.

The formula for slope between two points (x₁, y₁) and (x₂, y₂) is,

m = (y₂ - y₁)/(x₂ - x₁)

The given equation is,

y = 2 - 3x

The slope of the equation m = -3.

To find the slope of the table, take any two points, because given line is straight line. Therefore, slope will be equal for every point.

(A)

Slope m = (5-2)/(1-0) = 3

(B)

Slope m = (8-10)/ 4-2 = -2 / 2 = -1

(C)

Slope m = (7-10)/1-0 = -3.

Hence, slope of table (C) is -3.

Answer:

The correct option is A: 4.29 N.

Step-by-step explanation:

The magnetic force is given by:

[tex] F = qv\times B = qvBsin(\theta) [/tex]

Where:

q: is the charge = 7.12x10⁻⁶ C

v: is the speed = c/2 = 1.5x10⁸ m/s

B: is the magnetic field = 4.02x10⁻³ T

θ: is the angle = 90° (the speed is perpendicular to the magnetic field)

Hence, the force on the charge is:

[tex]F = qvBsin(90) = 7.12 \cdot 10^{-6} C*1.5 \cdot 10^{8} m/s*4.02 \cdot 10^{-3} T = 4.29 N[/tex]

Therefore, the correct option is A: 4.29 N.

I hope it helps you!
