Answer:
The slope is: 
Step-by-step explanation:
The equation for slope is:
Point 1: -3=
, -2=
Point 2: 5=
, 4=
4-(-2)=6
5- (-3)=8
6/8=3/4
The correct answer is the second one, I already answered it.
Answer:
128°
Step-by-step explanation:
x + 154° + 78° = 360° {being complete turn}
x + 232° = 360°
x = 360° - 232°
x = 128°
Answer:
Step-by-step explanation:
<u>Given function:</u>
The base of the exponent is 0.92. This represents a decay as 0.92 is less than 1. It would be a growth function is the base was greater than 1.
<u>The rate of decrease is </u>
<u>Percent decrease is </u>
Answer:
18+12.125π units²
Step-by-step explanation:
The diameter of the semicircle can be found by the use Pythagoras theorem.
Δx²+Δy²=d²
Δx=3--1=4
Δy=3--6=9
d²=4²+9²
d=√(16+81)
Area=πr²/2
=π×(√(16+81)/2)²÷2
=[π×(97)/4]/2
=97π/8
=18+12.125π units²
97π/8 is equivalent to 18+12.125π units²
