Answer:

The other endpoint is (-27,1)

Step-by-step explanation:

The midpoint is (x1+x2)/2 , (y1+y2)/2 = -22, -7

-22 = (x1+x2)/2

One of the endpoints is (-17,-15)

-22 = (-17+x2)/2

Multiply by 2

-22*2 = -17+x2

-44=-17+x2

Add 17 to each side

-44+17 = -17+17+x2

-27 = x2

-7 = (y1+y2)/2

One of the endpoints is (-17,-15)

-7 = (-15+y2)/2

Multiply by 2

-7*2 = -15+y2

-14 = -15+y2

Add 15 to each side

-14+15 = 15-15+y2

1 = y2

The other endpoint is (-27,1)

What is the surface area for this?
IrinaK [193]

Answer:

143 cm²

Step-by-step explanation:

There are 3 pairs of sides to this shape,

1 pair is the top and bottom pieces, each has an area of 4(3) = 12 cm², so there are 24 cm² from this pair.

the second pair is the front and back pieces, each has an area of

4(8.5) = 34 cm², so there are 68 cm² from this pair.

the third pair are the side pieces, each has an area of

3(8.5) = 25.5 cm², so there are 51 cm² from this pair.

Al together there are 24 + 68 + 51 = 143 cm²

2/9 - 7/12

First, multiply to find a common denominator. Multiply both pieces of the left fraction by 12, and both pieces of the right fraction by 9.

24/108 - 63/108 = -39/108 = -13/36

a= -13
b= 36

A student wants to determine the coefficients of static friction and kinetic friction between a box and a plank. She places the
Arturiano [62]

Answer:

the coefficients of static friction is 0.577

the coefficients of fkinetic friction is 0.54

Step-by-step explanation:

given information

θ = 30°

S = 2.5 m

t = 4 s

- Static friction

F - F(friction) = 0

W sin θ = μs W cos θ  

μs = sin θ/ cosθ

   = tan θ

   = tan 30°

   = 0.577

- kinetic friction

S = v_{0} t + \frac{1}{2} at^{2}

v_{0} t = 0

S = \frac{1}{2} at^{2}

a = \frac{2S}{T^{2} } = \frac{2 x 2.5}{4^{2} }

  = 0.3 m/s^{2}

F - F(friction) = m a

W sin θ - μ W cos θ  = m a

mg sin θ - μk mg cos θ  = m a

g sin θ - μk g cos θ  = a

μk = g sin θ  - a / g cos θ

    = 9.8 sin 30° - 0.3 / 9.8 cos 30°

    = 0.54
