All are congruent. Congruent means identical in size or shape. the different markings on the two shapes show that they are congruent. I can’t fully see number 10 so I can’t say it that one is or not

Answer:

a ) x = - 3, y = 5

x = 0, y = 2

x = 5, y = - 3

b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.

Step-by-step explanation:

y = 2 - x

When x = - 3,

y = 2 - x

= 2 - ( - 3 )

= 2 + 5

y = 7

When x = 0,

y = 2 - x

= 2 - 0

y = 2

When x = 5,

y = 2 - x

= 2 - 5

y = - 3

b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.

HELPPPPP! WILL Give BRAINLIEST! 100 POINTS! Please get it correct!

Answer:

11.26 cm²

Step-by-step explanation:

The shaded region is the difference of areas of semicircle AB and triangle ABC.

ABC is right triangle as AB is diameter, so C is right angle.

Area of semicircle:

A = 1/2πr² = 1/2*3.14*4² = 25.12 cm²

Area of triangle:

A = 1/2BC*AC = 1/2*4* $\sqrt{8^2-4^2}$ = 2 $\sqrt{48}$ = 13.86 cm²

Shaded are is:

25.12 - 13.86 = 11.26 cm²

Solution

write the division as a fraction = 12y^4-4y^3 - 6y^2 + 36y - 22 over y-3 multiplied by r over y-3

r ×(2y^4 - 4y^3- 16y^2 + 36y- 22) over (y-3)^2

2ry^4 - 4ry^3 - 16ry^2 + 36ry - 22r over (y-3)^2

Method of Least Squares, Evaluation of Cost Equation Lassiter Company used the method of least squares to develop a cost equatio

maksim [4K]

Solution :

1). The cost of the formula is given as :

$ 19,350 + $12 x

2). 95% $\text{confidence interval}$ for the prediction is :

$21430 - 1.96 \times 220 < \text{Yf} < 21430+1.96 \times 220$

$20998.8 < \text{Yf} < 21861.2$

$20999 < \text{Yf} < 21861$ (rounding off)

3). r = 0.92

Therefore, $r^2 = 0.8464$

That is 84.64 % of the variability in the moving cost is best explained by the number of moves.
