Leonard made the 3-d shape below for an art project. He wants to paint it blue.
tia_tia [17]

Answer:

90 cm^{2} of blue paint

Step-by-step explanation:

From the given diagram, the sides have the same dimensions and the shape of a triangle.

Area of a triangle = \frac{1}{2} x base x height

Given that, the base of each side = 6 cm, and the height = 10 cm.

Then,

Area of each side of the shape = \frac{1}{2} x 6 x 10

                                              = 30 cm^{2}

Since Leonard wish to paint only the 3 sides and not the bottom part of the shape, the amount of paint required can be determined as;

3 x area of each side = 3 x 30

                                   = 90 cm^{2}

Leonard would need 90 cm^{2} of paint to paint the sides of the shape.

Where do (3/2,-7) and (-4,5) intercept
Vinil7 [7]

Answer:

The intercept of the given points is -  \frac{41}{11}

Step-by-step explanation:

Given points as :

( x_1 , y_1 ) = ( \frac{3}{2} , - 7 )

( x_2 , y_2 ) = ( - 4 , 5 )

Now, slope of line using given points can be written as :

Slope = m = \dfrac{y_2 - y_1}{x_2 - x_1}

or. m = \dfrac{5 - ( - 7 )}{( - 4 ) -  [tex]\frac{3}{2}}[/tex]

or, m = \dfrac{12}{( - 4 ) -  [tex]\frac{3}{2}}[/tex]

or, m = \frac{12}{\frac{- 8 - 3}{2}}

Or, m =  \frac{12}{\frac{- 11}{2}}

∴   m = \frac{-24}{11}

So, The slope of the line using points = m = \frac{-24}{11}

now, equation of line in slope intercept form can be written as

y - y_2 = m × ( x - x_2 )

or, y - 5 =  \frac{-24}{11} × ( x - ( - 4 ) )

or, y - 5 =  \frac{-24}{11} × ( x + 4 )

Or, 11 × ( y - 5 ) = - 24 × ( x + 4 )

Or, 11 y - 55 = - 24 x - 96

Or, 11 y = - 24 x - 96 + 55

Or, 11 y = - 24 x - 41

∴  y = \frac{-24}{11} x -  \frac{41}{11}

Now, comparing with slope intercept equation

I.e y = m x + c           , where c is the intercept

So, The intercept of points is  -  \frac{41}{11}

Hence The intercept of the given points is -  \frac{41}{11} Answer
