Answer:

The volume is 40ft^{3}

Step-by-step explanation:

We are able to solve this using the following equation

V = \frac{lwh}{3} = \frac{(5)(4)(6)}{3} = 40

Hope this helps!

Find the surface area of a pentagon-based pyramid with slant height of 11 m.
Ronch [10]

Answer:

108.75 square meter.

Step-by-step explanation:

<h3>Surface area of pentagon based pyramid:</h3>

   \sf \boxed{\text{\bf Surface area of pentagonal pyramid = $ \bf \dfrac{5}{2}*b*(a + s)$}}

  Here,  b is the base length of the pyramid. b = 3 m

              a is the apothem of the pyramid. a = 3.5 m

              s is the slant height of the pyramid. s = 11 m

     \sf Surface \ area = \dfrac{5}{2}*3*(11 + 3.5)

                         \sf = \dfrac{5}{2}*3*14.5\\\\     = 108.75 \ m^2

Eva draws a line that includes the points (2,0) and (-2,2). Which function gives all the points (x,y) on this line?
user100 [1]

Answer:

The function that gives all the points on the line is y = 1-0.5x

Step-by-step explanation:

To calculate the function, we need to give the equation of the straight line that joins the two points.

mathematically, we can represent the equation of a straight line as;

y = mx + c

where m is the slope and c is the y-intercept

Let’s first calculate the slope using the two points we have

mathematically

m = (y2-y1)/(x2-x1)

where (x1,y1) = (2,0) and (x2,y2) = (-2,2)

Plugging these values into the equation we have;

y = (2-0)/(-2-2) = 2/(-4) = -1/2 or simply -0.5

Now we need to get c

The equation in its current state is

y = -0.5x + c

we can use any of the points to get c.

Let’s use (2,0); here x = 2 and y = 0

0 = -0.5(2) + c

0 = -1 + c

c = 1

Thus our equation is;

y = -0.5x + 1

or simply

y = 1-0.5x
