An arithmetic sequence is a sequence of numbers with a common difference.
In the choices above, only A and D are arithmetic sequences.
<em>In A, the common difference is 2 while in D, it's 0 .1.
</em>
B can't be an arithmetic sequence since the number 1 is just being repeated many times, there's no progression.
C as well. Be observant of the pattern, it can be an arithmetic sequence only if it has 4 before 5.
E obviously is not an arithmetic sequence. If you try to find the difference between the consecutive terms, it's not common.
Answer:
2040 m3
Step-by-step explanation:
you see in the pic, the shape may cut into 2 pieces, this is 1/2 of the shape.
so we take (24*10*17)/2=2040 m3.
Hope it helps you
Answer:
x = 2.121
Step-by-step explanation:
1. sin 45° = x/3
2. x = sin45° × 3 = 2.121
Answer:
50% chance
Step-by-step explanation:
2/4 marbles = 0.50 = 50%
Answer:
Step-by-step explanation:
Remark
- x is opposite the 90 degree angle. It is the hypotenuse.
- 13 makes up the 57 degree angle. It is the side adjacent.
- The adjacent side and the hypotenuse define the cos(theta).
Formula
cos(theta) = adjacent side / hypotenuse
Givens
Theta = 57 degrees
Hypotenuse = x
Side adjacent = 13
Solution
- Cos(57) = 13 / x Multiply both sides by x
- x*cos(57) = 13 Divide by cos(theta)
- x = 13/cos(57)
- x = 13 / cos(57)
- cos(57) = 0.5446
- x = 13/ 0.5446
- x = 23.87
