Answer:
y = -0.5x + 3
Step-by-step explanation:
The equation of a linear model is generally represented as;
y = mx + b
where m
is slope and b is the y-intercept
We can get slope by using the slope equation
m =
(y2-y1)/(x2-x1)
(x1,y1) = (-4,5)
(x2,y2) = (4,1)
m = (1-5)/(4 + 4) = -4/8 = -0.5
The equation is thus;
y = -0.5x + b
to get b, we substitute any of the two points coordinates
1 = -0.5(4) + c
1 = -2 + c
c = 2 + 1
c = 3
Use the Pythagorean theorem. a^2+b^2=c^2
16^2+31^2=x^2
Then take the square root. You cannot do this theorem without squaring all of the numbers and taking the square root.
The area of the sector is 86.81π mm²
<u>Explanation:</u>
Given:
Radius of the sector, 25mm
Angle, α = 50°
Area of the sector, A = ?
We know:
Area of the sector =
On substituting the value, we get:
Therefore, the area of the sector is 86.81π mm²
Answer:
32 extra goodie bags mark brainlist pls
Step-by-step explanation:
You do 120x4=480
then do 25x3=75
then add 480+75=555
then do 635.00- 555= 80
then do 80 divided by 2.50= 32
