Answer:
The answer is B because if you take the line of y=-x (which you can look up on desmos if you don't know what y=-x looks like) and reflect over that line you can see that when the dot reflects over the line y=-x it goes to points (0,2)
Step-by-step explanation:
The first term, a, is 2. The common ratio, r, is 4. Thus,
a_(n+1) = 2(4)^(n).
Check: What's the first term? Let n=1. Then we get 2(4)^1, or 8. Is that correct? No.
Try this instead:
a_(n) = a_0*4^(n-1). Is this correct? Seeking the first term (n=1), does this formula produce 2? 2*4^0 = 2*1 = 2. YES.
The desired explicit formula is a_(n) = a_0*4^(n-1), where n begins at 1.
It would be 82 2/3 since 1/3 minis 2/3 would equal -1/3 you subtract that from 83 and get 82 2/3
Answer:
m∠3 = 70°
Step-by-step explanation:
By the properties of a parallelogram,
- Opposite angles of a parallelogram are equal in measure.
- Adjacent angles of a parallelogram are supplementary angles.
m∠2 = m∠4 and m∠1 = m∠3
4x + 30 = 2x + 70
4x - 2x = 70 - 30
2x = 40
x = 20
Therefore, m∠2 = m∠4 = 110°
Since, m∠2 + m∠3 = 180°
110° + m∠3 = 180°
m∠3 = 180° - 110°
m∠3 = 70°
Answer:
Step-by-step explanation:
Scale= 1:1,000,000
Scaled distance = 1.8 dm
Actual distance = 1.8*1,000,000 = 1,800,000 dm
