Answer:
a) -1
Step-by-step explanation:
Slope is also known as the gradient
1. assign a value to x and solve for y:
when x = 2, y = 2
when x = 4, y = 0
2. Next, use the equation of a straight line to find the gradient
y = mx + c
y is the y-coordinate, m is the gradient, x is the x-coordinate, c is the point where the line crosses the y-axis, which is found by equating y to 0 and solving for x
so y = mx + c becomes 2 = m*2 + 4, which then becomes 2 = 2m + 4
2m = -2 (take 4 away from 2)
<u>m = -1 </u>
Question 1 demonstrates the Commutative Property.
Answer:
the length of an arc = 10π ft.
Step-by-step explanation:
The length of an arc with angle Θ and radius r will be equal r * Θ
note the angle must be in radian
Given: Θ = 180° = π and radius = r = 10 ft.
<u>So, the length of the arc = π * 10 = 10π ft.</u>
Answer:
sum of interior angles of the octagon is 1080 degree
Step-by-step explanation:
forluma:
(n-2)*180 degree
since octagon has 8 sides
(8-2)*180 degree
6*180
1080 degree
