It should've been:
(6.2-1.6)-4.4+7.8
6,2-1.6-4.4+7.8=4.6-4.4+7.8=0.2+7.8=8
Here, Vertices: A(-4, 0) B(-1, 6) C(3, -1)
Length of AB = √(6 - 0)² + (-1 + 4)²
= √6² + 3²
= √45
Length of BC = √(-1-6)² + (3+1)²
= √-7² + 4²
= √65
Length of AC = √(0+ 1)² + (-4 - 3)²
= √1² + 7²
= √50
Perimeter = sum of all sides:
So, P = √45 + √65 + √50 = √160 = 4√10
In short, Your Answer would be 4√10 units
Hope this helps!
Answer:
a) C
b) A
Step-by-step explanation:
The wingspan is the dependent variable while the bird height is the independent variable.
a) Since R2 is the dependent variable, it can be expressed by the independent variable. An R2 of 93% represents 93% of the variation in the wingspan which can be explained by using the birds height. This means that the appropriateness of the model should not be determined by R2 but by using a scatter plot.
b) The model predicts the value of wingspan using the value of bird height. We cannot say that the bird 10 inches tall has a wingspan if 17 inches instead, we say that the wingspan of the bird which is 10 inches tall is 17 inches.
It is therefore possible that the wing span is not exactly 17 inches
Answer:
x = 29
Step-by-step explanation:
The three angles of a triangle add to 180
x+90+61 = 180
Combine like terms
x+151 = 180
Subtract 151 from each side
x+151-151 = 180-151
x = 29
The answer is A 4,3 is the coordinates at Which the two lines meet
