Answer:
B. 2
Step-by-step explanation:
1) all the perpendicular lines are: y=x+C, where C - number;
2) in order to calculate C: to substitute (2;4) into the equation y=x+C:
4=2+C; ⇒ C=2;
3) finally, the required equation is: y=x+2.
The answer is B. 2.
An+1= 3n+3 +2
An+1 - An = <span>3n+5 -3n-2=3
An is aa arithmetic sequence
its sum is given by:
A0 +A1 +A2 + . . . + An = N(Ao + An) /2
where N = n-0=n
</span><span>S50= A0 +A1 +A2 + . . . + A50 = 50(Ao + A50) /2
</span>
S50 = 50(Ao + A50) /2
Ao=2, A50=150+2=152
S50= <span>50(Ao + A50) /2
</span>
finally
<span>S50=25*154=3850</span>
Answer:
7) Similar; 8) not similar; 9) ⅔; 10) ⅘
Step-by-step explanation:
Two polygons are similar if
- their corresponding angles are congruent and
- the ratios of their corresponding sides are equal
7) Trapezoids
Corresponding angles are congruent.

Corresponding sides are in the same ratio, so the trapezoids are similar.
8) Rectangles
Corresponding angles are congruent.

The ratios are different, so the rectangles are not similar.
In similar polygons, the ratio of the lengths of their corresponding sides (the scale factor) is the same.
9. Quadrilaterals

10. Trapezoids
