Find the 40th term of this arithmetic sequence.

1 answer:

5 0

199 is the answer because the equation you use is an=a1+d(n-1). Where an (the n is actually supposed to be smaller than the a) is the nth term (a40), a1 (1 smaller than a) is the first term (4), d is the difference (5), and n is the number of the term you're looking for (40)

ABCD is a rectangle. Find the length of each diagonal.ac=2(5a+1) bd=2(a+1).

Igoryamba

Rectangle diagonals are equal.

2(5a+1) = 2(a+1)
10a + 2 = 2a + 2
10a -2a = 2 - 2
8a = 0
⇒ a = 0

AC = 2(5a+1) = 2(5 × 0 +1)= 2(0 + 1) = 2 × 1 = 2 <span>
</span>BD = 2(a+1) = 2(0 + 1) = 2 <span>× 1 = 2
</span>
Ansver: AC = BD = 2

Help me , this is my homework (Geometry) . I really need help

8. Similar parts

$\dfrac{6}{18} = \dfrac{AQ}{12}$

$AQ = 12(6)/18=12/3=4$

Choice a

9. The Law of Sines says a:b:c and $\sin A : \sin B \sin C$ are the same ratio.

The sines will go in order for acute angles, we have to convert 120 to its supplement 60 and then the order is 29,31,"60" or opposite sides JK, KL, JL

choice b

10.

DEF and FEG are supplments, FEG=180-DEF=180-114=66

DEF and HEG are opposite angles, so congruent HEG=DEF=114

Answer:

Angle ZXY = 41 degrees.

Step-by-step explanation:

If WX is parallel to ZY then angle XZY = 71 degrees.

Angle ZXY = 180 - 68 - 71 = 41 degrees.
