Find the inequality represented by the graph - khan academy<br> PLEASE HELP

Andru [333]

Answer:

y ≤ x - 1

Step-by-step explanation:

The slope is 1 (every unit for x, there is a unit for y, rise/run is 1/1). The y-intercept is -1, because the line crosses the y-axis at -1. The graph is shaded below the line, and the line is solid, meaning that y is less than or equal to x -1, or y ≤ x - 1.

If F(x)= x2+2x-3 and g(x)=x2-9 , find (f/g)(4) and(f+g)(4) .(f/g)(4) is , and (f+g)(4) is .

Alexandra [31]

F(x) = x2+2x-3 = 1
g(x) = x2-9 = -7

(f/g)(4) = (1/-7)(4) = (-0.14)(4) = -0.57
(f+g)(4) = (1+(-7))(4) = (-6)(4) = -24

What is (f-g)(x)?<br><br> question equation show in picture

likoan [24]

Answer:

(f-g)(x) = x^4 - x^3 - 4x^2 - 3

Step-by-step explanation:

(f-g)(x) = x^4 - x^2 + 9 - (x^3 + 3x^2 + 12)

(f-g)(x) = x^4 - x^2 + 9 - x^3 - 3x^2 - 12

(f-g)(x) = x^4 - x^3 - 4x^2 - 3

a pole that is 3.3 M tall casts a shadow that is 1.22 M long at the same time a nearby Tower cast a shadow that is 50.75 M long

jenyasd209 [6]

Since there is no distance between the pole and the base of the tower, we can assume that the pole is at the base of the tower.
We can create a right triangles between the pole and its shadow and between the tower and its shadow as shown in the figure. Let $x$ be the height of the tower. Since our triangles are similar the ratio between its sides is going to be proportional, so we can establish a proportion to find $x$ :
$\frac{x}{3.3} = \frac{50.75}{1.22}$
$x= \frac{(50.75)(3.3)}{1.22}$
$x=137.27$

We can conclude that the tower is 137.27 meters tall.
