What is the mechanical advantage of a hockey stick that is gripped at point D and hits the puck at point B?

Answer: Mechanical advantage = Effort distance/Resistance distance

Effort distance = D - Fulcrum = 0.5 m

Resistance distance = A - Fulcrum = 2.0 m

Then,

Mechanical advantage = 0.5/2 = 0.25

Hockey stick is an example of third class where mechanical advantage is less than one as the speed of the end of point A is critical.

Answer:

Mechanical advantage = Effort distance/Resistance distance

Effort distance = D - Fulcrum = 0.5 m

Resistance distance = A - Fulcrum = 2.0 m

Then,

Mechanical advantage = 0.5/2 = 0.25 

Hockey stick is an example of third class where mechanical advantage is less than one as the speed of the end of point A is critical.

help please! what is the equation of the line described below written in slope-intercept form? the line passing through point (4
Lunna [17]
For perpendicular lines, m1m2 = -1 or m2 = -1/m1; where m1 and m2 are the slopes of the lines.
Here line 1 is 2x - y - 7 = 0
y = 2x - 7; Hence m1 = 2
m2 = -1/2
Required equation y - y1 = m2(x - x1)
y - (-1) = -1/2(x - 4)
y + 1 = -1/2x + 2
y = -1/2x + 2 - 1
y = -1/2x + 1

Gnom [1K]

Answer:

m<1 = 175 degrees

Step-by-step explanation:

3x + 10 = 2x + 15

-2x - 10 = -2x - 10

x = 5

180 - 5 = 175 degrees

Multiply the polynomials.
dezoksy [38]

48x^3-4x^2+18x-40 \text{ is the product of } (8x^2+6x+8)(6x-5)

<em><u>Solution:</u></em>

Given that we have to multiply the polynomials

(8x^2+6x+8)(6x-5)

Multiplying polynomials is similar to multiplying numbers

When you multiply two terms together you must multiply the coefficient (numbers) and add the exponents

Let us multiply the given polynomials

\rightarrow (8x^2+6x+8)(6x-5)

Multiply each term in first bracket with each term in second bracket

\rightarrow (8x^2)(6x) -5(8x^2)+6x(6x)+6x(-5)+8(6x)+8(-5)

Add the exponents and multiply the coefficients

\rightarrow 48x^3-40x^2+36x^2-30x+48x-40

Combine the like terms -30x and 48x

\rightarrow 48x^3-40x^2+36x^2+18x-40

Combine the like terms -40x^2 \text{ and } 36x^2

\rightarrow 48x^3-4x^2+18x-40

Thus the polynomials has been multiplied
