This section of a concrete skateboard ramp has the shape of a triangular prism. Find the volume of the triangular prism. Find the value of the concrete used in the ramp if the cost of concrete is $3.00 per cubic foot. 6ft 6ft 10.2ft

$550.80

Step-by-step explanation:

Value of concrete used = volume of the prism x cost per cubic foot

volume of the prism = base area x height

the base is in the shape of a triangle

Area of a triangle = (1/2) x base x height = 1/2 x 6 x 6 = 18

Volume of the prism = 18 x 10.2 = 183.6 ft^3

183.6 x 3 = $550.80

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
