Answer:
28
Step-by-step explanation:
Since the triangle is a right triangle, we can use SOH CAH TOA to find ?. 10 is OPPOSITE to ? and 21 is HYPOTENUSE to ?, so we can use SIN to find ?.
SIN(?) = 10/21
? = ARCSIN(10/21)
? = 28.437
It is less because 8(2/8) would equal 2
Answer:
Correct answer: a = 3 · 4⁽ⁿ ⁻ ¹⁾
Step-by-step explanation:
Given:
Geometric sequence 3, 12, 48, 192, .....
First term a₁ = 3
Second term a₂ = 12
Third term a₃ = 48
Common ratio or quotient:
q = a₂ / a₁ = a₃ / a₂ = 12 / 3 = 48 / 12 = 4
q = 4
First term a₁ = 3
Second term a₂ = a · q
Third term a₃ = a₂ · q = a₁ · q²
Fourth term a₄ = a₃ · q = a₁ · q³
......................................................
n- th term aₙ = a₁ · q⁽ⁿ ⁻ ¹⁾
In this case aₙ = 3 · 4⁽ⁿ ⁻ ¹⁾

Answer:
YES
Step-by-step explanation:
Find each length using the distance formula,
✔️Distance between A(-4, 2) and B(1, 4):
Let,
✔️Distance between C(2, -1) and D(4, 4):
Let,
AB = CD = √29
Therefore, they both have the same length.
