Answer:
Step-by-step explanation:
hello :
the general term is : An =A1×r^n when A1 =30 r=1/2
the fourth term is :A4 when n = 4
A4= 30×(1/2)^4 = 30/16 = 15/4
A) 4*c + 2*D = 78
B) C + D =27
Multiplying B) by -2 equals
B) -2 C -2 D = -54 then adding equation A)
A) 4*c + 2*D = 78
2C = 24
Cows = 12
Ducks = 15
********************************** DOUBLE CHECK
B) C + D =27
12 + 15 = 27
Correct!
Answer:
I think 8/5
Step-by-step explanation:
from X=2 to X=10 its 8 spaces and from Y=2 to Y=7 its 5 spaces, not 100% sure of this but seems right. :)
This is in the 3rd quadrant, so -12 is the adjacent side of the 5,12,13 triangle.
Cot(theta) = -12/(-13) = 12/13
I believe the correct answer is the second option. The correct despcription of the said figure would be a rectangle since from the choices it is the only shape where all angles are the same value which is 90. A kite can have different angles at each corner. A rhombus has two pairs of different angle measurements as well as a trapezoid.
