Answer:
The residual of the point 
in the equation 
is 
Step-by-step explanation:
We have been given point where 
.
Now the equation is .
Plugging the value of in the equation of ,
we have to find the predicted value of y and 
.
So y predicted 
.
To find the residual point we have to subtract the actual value from the predicted value.
As actual value of 
along with the points .
Residual point = Actual value - Predicted value.
So the residual for the point is 
.
Answer:
The first step in simplifying this expression is to evaluate the terms within the parenthesis - starting with the multiplication and following the rules for operations in math.
The ratio of a 45-45-90 triangle is x-x-xrad2
So we can make the equation 44=xrad2
we can see that the answer is 22rad2 so the answer is b
Answer:
19) 28°
20) 60°
21) 17°
Step-by-step explanation:
19)
Supplementary angles:
(x + 12)º + 140º = 180º
x + 12 + 140 = 180
x = 180 - 140 - 12
x = 28º
20)
Angles at a point:
(- 24 + x)° + 24° + 300° = 360°
- 24 + x + 24 + 300 = 360
x = 360 - 300
x = 60°
21)
Vertically opposite angles:
(1 + 3x)° = 52°
1 + 3x = 52
3x = 52 - 1
3x = 51
x = 17°
Answer:
x = 4.17
Step-by-step explanation:
We can use a ratio to solve
4.2 k 2 k
---------------- = ---------------
8.76 x
Using cross products
4.2 * x = 2 * 8.76
4.2x =17.52
Divide by 4.2
x=4.17
