Mathematics

arsen [322]3 years ago

Answer:

No

Step-by-step explanation:

If the lines are perpendicular then they will be the negative reciprocals of each other.

Calculate the slope using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = P(- 8, - 10) and (x₂, y₂ ) = Q(- 5, - 12)

m_{PQ} = \frac{-12+10}{-5+8} = - \frac{2}{3}

Repeat the process with

(x₁, y₁ ) = R(9, - 6) and (x₂, y₂ ) = S(17, - 5)

m_{RS} = \frac{-5+6}{17-9} = \frac{1}{8}

The slopes are not the negative reciprocal of each other, thus they are not perpendicular.

A craftsman is making a dulcimer with the same dimensions as the one shown. The surface shown requires a special, more durable t
Bogdan [553]

Answer:

\displaystyle A=\frac{3h^2}{2}+h

Step-by-step explanation:

<u>Area of trapezoid</u>

Given a trapezoid shape whose parallel sides measure b1 and b2 and whose height (perpendicular to the base) is h, then the area of the trapezoid is given by

\displaystyle A=\frac{b_1+b_2}{2}\cdot h

The dulcimer has the following dimensions

b_1=2h+1

b_2=h+1

and height h

Thus

\displaystyle A=\frac{2h+1+h+1}{2}\cdot h=\frac{3h+2}{2}\cdot h

Operating

\displaystyle A=\frac{3h^2+2h}{2}=\frac{3h^2}{2}+h

\boxed{A=\frac{3h^2}{2}+h}

Is the required polynomial

(Algebra II) Extra points!!Determine whether y varies directly with x
ludmilkaskok [199]

Answer:

  • k = 1.6
  • y = 1.6x

Step-by-step explanation:

If the variation is proportional dividing the y-value by the x-value will give the same result for all table entries. That quotient is the constant of variation (k).

Here 6.4/4 = 11.2/7 = 16/10 = 20.8/13 = 1.6

The value of y varies directly as x, and the constant of variation is 1.6. The equation is ...

  y = 1.6x

lakkis [162]

Answer:

\frac{x}{3}  + 4 =  \frac{4x - 1}{5}  \\  \\  \frac{x}{3}  +  \frac{12}{3}  =  \frac{4x - 1}{5}  \\  \\  \frac{x + 12}{3}  =  \frac{4x - 1}{5}  \\  \\ 3(4x - 1) = 5(x + 12) \\  \\ 12x - 3 = 5x + 60 \\  \\ 12x - 5x = 60 + 3 \\  \\ 7x = 63 \\  \\ x =  \frac{63}{7}  \\  \\ x = 9
