Answer:
see explanation
Step-by-step explanation:
An open circle indicates that x cannot equal that value
A closed circle indicates that x can equal that value.
(i)
An open circle at x = - 1 and arrow pointing right
x > - 1
(ii)
An open circle at x = - 1.5 and arrow pointing right
x > - 1.5
(iii)
A closed circle at x = 4 and arrow pointing left
x ≤ 4
(iv)
A closed circle at 0.5 and arrow pointing left
x ≤ 0.5
Answer:
The answer to your question is:
5) slope = 0
6) slope = 0.7
7) slope = 0.04
8) slope = 21.7
Step-by-step explanation:
Slope is the tangent of the angle form between a line and the x-axis.
So
15)
there is no slope, then m = 0
16)
Here we have the legs of a right triangle so we can find the tangent
tangent = opposite leg / adjacent leg
tangent = 70 / 100 = 0.7
17)
Also here, we can imagine a right triangle
tangent = 15 / 384 = 0.04
18) Also here we have a right triangle
tangent = 13000 / 600 = 21.7
Answer:
b. -79.8.
Step-by-step explanation:
We calculate what's in the brackets first:
46 - 65
= -19
Now multiply by 4.2:
-19 * 4.2
= -79.8.
We know the opposite and adjacent sides of angle B, so we can use the inverse tangent to solve for its value.
tan(B)^-1 = 3/4
B = 64.4 degrees
