Can somebody help me with my geometry?
ahrayia [7]
The slope of AC is -0.4

Proof:
In triangles ABC and DBE,
∠DBE is common to both triangles.
AB = 2DB (D is the midpoint of the interval AB)
Also, BC = 2BE (E is the midpoint of the interval BC)

Thus triangles ABC and DBE are similar in the ratio 2:1

Since, they are similar, ∠BDE must equal ∠BAC (corresponding angles in similar triangles)

If ∠BDE = ∠BAC, DE must be parallel to AC (corresponding angles are equal along parallel lines)
Thus, the slope of AC = the slope of DE
Thus, the slope of AC is -0.4

Use the formula below to find the value of $1300 invested at 4.2% interest compounded continuously for 5 years 9 months. Round y
iren2701 [21]
Hi there

The formula of compounded continuously is
A=pe^rt
A future value?
P present value 1300
E constant
R interest rate 0.042
T time 5years+9/12=5+9/12=5.75years
So
A=1,300×e^(0.042×5.75)
A=1,655.10 round your answer to get
A=1655

Good luck!

4+10(5-3) = 4 +62 is what?<br> O 18<br> O 42<br> O 21<br> O45
Shtirlitz [24]

Hey there!

4 + 10(5 - 3) = 4 + 62

4 + 10(5) + 10(-3) = 4 + 62

4 + 50 - 30 = 4 + 62

54 - 30 = 4 + 62

24 = 4 + 62

24 = 66

24 ≠ 66


OR

4 + 10(5 - 3) = 4 + 62

4 + 10(2) = 4 + 62

4 + 20 = 4 + 62

24 = 4 + 62

24 = 66

24 ≠ 66


Thus, this statement is FALSE because both of your numbers aren’t equivalent to each other.


But, let’s try this method

4 + 10(5 - 3) = 4 + 62

4 + 10(2) = 4 + 62

4 + 20 = 4 + 62

24 = 66

24 ≠ 66

66 - 24 = 42

Thus, if this is what your question is asking it would be: Option B. 42


Good luck on your assignment and enjoy your day!
