Answer:
The terms are {81, 27, 9, 3}
Step-by-step explanation:
A recursive formula uses the previous number in a sequence to find the new number. The given formula just divides the previous term by 3.
So:
Term 1: 81
Term 2: 81/3 = 27
Term 3: 27/3 = 9
Term 4: 9/3 = 3
Answer:
<h2>m∠2 = m∠1</h2><h2>m∠1 = 75°</h2>
Step-by-step explanation:
Look at the picture.
Vertical angles, corresponding angles, alternate exterior angles are congruent.
Supplementary angles add up to 180°.
Answer:
Answer is A - (1, 3) and (2, 6)
Step-by-step explanation:
(1, 3) • 2
= (1 • 2, 3 • 2)
= (2, 6)
Ratio: 2/2, 6/2
Therefore, the answer is A.
So the angle of elevation to the light source is:
tanα=h/x
α=arctan(h/x)
α=arctam(50/75)°
α≈33.69°
Answer:
16:1
Step-by-step explanation:
The ratio of the surface areas of the similar solids is the square of the lengths.
(4:1)²
4²:1²
⇒ 16:1
