Answer:
X : Z = 6 : 5
Step-by-step explanation:
X : Y = 3 : 1
Double both sides
X : Y = 6 : 2
Y : Z= 2 : 5
Combined
X : Y : Z = 6 : 2 : 5
Therefor
X : Z = 6 : 5
Answer:
The first choice
Step-by-step explanation:
Perpendicular lines intersect to form right angles, like the x- and y-axis on a coordinate plane.
Answer:
Los triangulos son iguales porque tienen dos lados y el angulo comprendido respectivamente iguales, por tanto
Answer:
x = 1/64
Step-by-step explanation:
2x = 1/32
Divide both sides by 2.
Simplify, and you will get 1/64.
Answer:
an = −1,171,875(1/5)^n-1
Step-by-step explanation:
The given sequence is geometric sequence since they have the same common ratio r. The nth term of a geometric sequence is expressed as;
an = ar^n-1
n is the number of terms
r is the common ratio
a is the first term
From the sequence;
a = −1,171,875
r = −234,375 /−1,171,875 = -46,875/−234,375 = 0.2
r = 1/5
Substitute the values in the formula;
an = −1,171,875(1/5)^n-1
Hence the required explicit formula is an = −1,171,875(1/5)^n-1
