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

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!

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:

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.

Answer:

[tex]14m^{2} + 6w^{2} + 18w +22[/tex]

Step-by-step explanation:

Break the function into pieces and combine like terms:

[tex](9m^{2}+5^{2})=14m^{2}[/tex]

[tex]6w^{2}[/tex]

[tex](14w+4w)=18w[/tex]

[tex](10+12)=22[/tex]

Now arrange the pieces in proper order (order of exponents)

The y-intercept of the exponent function is 4. Then the graph represents the equation y = 4(3)ˣ will be B.

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as

y = a(b)ˣ

The exponent equation is given below.

y = 4(3)ˣ

The value of the exponent function at x = 0 is calculated as,

y = 4(3)⁰

y = 4 × 1

y = 4

The y-intercept of the exponent function is 4. Then the graph represents the equation y = 4(3)ˣ will be B.

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:

7n+700≥1,150 and 65 shirts

Step-by-step explanation:

The answer is 65 instead of 64 because there is a decimal of .287...

This means we have to round up in order to be correct, not down because then it wouldn't be enough.

The inequality represents the minimum number of shirts, n, the band must sell to earn the remaining money is, 7n + 700 > 1150.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

From, The given information le the number of t-shirts be 'n'.

Therefore, The inequality representing the minimum number of shirts, n, the band must sell to earn the remaining money is,

7n + 700 > 1150.

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:

12565.11 teeth approximately cut cross the cutting surface per seconds.

Step-by-step explanation:

Since the diameter is 10inches, the circumference of the arm saw is 10π (circumference is πd where d is diameter).

The number of teeth on the cutting blade can be gotten by multiplying the diameter by 12 since we have 12 teeth per inch on the arm saw

Number of teeth on saw = 12 x 10π = 120π.

To get the number of teeth that cross the cutting surface in 2000rpm we multiple it by the total number of teeth in just one rpm.

So we have 2000 x 120π. But since we are asked to find it in revolution per seconds then 2000r/m = 2000r/60s ≈ 33.33

Therefore, we have

33.33 x 120π ≈ 12565.11 teeth
