A landscape architect submitted a design for a triangle shaped flower garden with side lengths of 21ft, 37ft, and 15ft to a cust

ollegr [7]

For a triangle, there is a proven inequality that states that, the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side

21 + 37 >= 15
58 >= 15

21 + 15 >= 37
36 >= 37

37 + 15 >= 21
52 >= 21

We can see that the second inequality doesn't comply, thus there is not such triangle.

Find (g*f)(3) f(x)=|x+2| g(x)=-x^2 a. -25 b. 1 c. d. -15

Musya8 [376]

$(g\cdot f)(x)=g(x)\cdot f(x)\\\\f(x)=|x+2|,\ g(x)=-x^2\\\\(g\cdot f)(3)=g(3)\cdot f(3)\\\\\text{Put the value of x = 3 to the equations of a functions:}\\\\f(3)=|3+2|=|5|=5\\\\g(3)=-3^2=-9\\\\(g\cdot f)(3)=(-9)(5)=-45\\\\Answer:\ \boxed{-45}$
