Answer:
875 square inches
Step-by-step explanation:
The lateral area of a triangular prism is the sum of the areas of the three rectangular faces:
13×25 +15×25 +7×25 = (13 +15 +7)×25 = 35×25
= 875 . . . square inches
_____
The area of a rectangle is the product of its length and width. As we have seen here, the lateral area is the product of the height of the prism and the perimeter of its base.
13.2*3=39.6= price of 3cds, which is also the price of 2 dvds
39.6/2=19.8= the price of 1 dvd
Answer:
g(x)=-8(3^x)
Step-by-step explanation:
Given: f(x)=3^x
Multiply by 8: f(x)=8(3^x)
Negate function: g(x)=-8(3^x)
Answer:
y is less than 3/4 x
Step-by-step explanation:
find the slope of line from the two points given. (0,0) and (4,3) which is y=3/4 x.
since the line is dashed, we know y cannot be equal to the values the line falls along, and since the shaded area is to the right, we know the values have to be less than.
