Answer:
<em>Domain:</em> -3 < x <2
<em>Range:</em> -4 < y < 5
<em>Is the graph a function?</em> No the graph isn't not, since the graph fails the <em>vertical line test</em>
Answer:
12 meters
Step-by-step explanation:
Looking at the problem we can see that it typifies a right angled triangle. The rope running from the top of the flagpole to the hook on the ground is the hypotenuse of the triangle. Let us call this hypotenuse c. Let the distance between the hook and the foot of the flagpole be b. Let the height of the flagpole be a.
From Pythagoras theorem;
c^2 = a^2 + b^2
a^2= c^2 - b^2
a= √c^2-b^2
From the question
c= 13 metres
b= 5 metres
a= the unknown
a= √c^2-b^2
a= √(13)^2 - (5)^2
a= √169 - 25
a= √144
a= 12 meters
Answer:
z = 9/2
Step-by-step explanation:
1/2z = 9 1/4?
z = 9/2
Explanation:
Simplify
9 x 1/4 → 9/4
Multiply 2 to both sides to cancel out the 2
1z = 9/4
Note: 1z is just z
