So for this, our equation is gonna be $(f-g)(x)=3x^{-4}-(x+2)$

Firstly, reverse the signs in (x+2) $(f-g)(x)=3x^{-4}-x-2$

Next, change 3x^-4 to 3/x^4, and your answer will be $(f-g)(x)=\frac{3}{x^4}-x-2$

The sides of the triangle occur in a ratio of 4 : 7 : 2, so if x is some positive number, then we can write each side's length in terms of x as 4x, 7x, and 2x.

The perimeter is 299 yd, so

4x + 7x + 2x = 299 yd

13x = 299 yd

x = (299 yd) / 13

x = 23 yd

Then the sides of the triangle have lengths of

4x = 4 • 23 yd = 104 yd

7x = 7 • 23 yd = 161 yd

2x = 2 • 23 yd = 46 yd

"Median" here refers to the side length between the shortest and longest sides, so the answer would be 104 yd.

A sail is in the form of a right triangle that is four times as high as it is wide. the sail is made from 18 square meters of ma

Lilit [14]

Answer:

Area = 1/2 b x h

18 = 1/2 ((x) x 4x)

18 =1/2 4x^2

36 = 4x^2

36/4 = x^2

9 = x ^2

x = 3

Base = 3 m

Height = 4 x base = 4 x 3 = 12 m
