Answer:
Angle BOY, why? because the lines indicate that the triangles are congruent
Step-by-step explanation:
From F.S 1, consider this series : 8, 1, 8, 8, 64, 64*8.
Again, consider the series 2, 1/4, 1/2, 1/8, 1/16, 1/(8*16). Clearly, the difference of the 6th and the 3rd term is different for them. Insufficient.
<span>From F.S 2, let the series be </span><span><span>a,b,ab,a<span>b2</span>,<span>a2</span><span>b3</span>,<span>a3</span><span>b5</span></span><span>a,b,ab,a<span>b2</span>,<span>a2</span><span>b3</span>,<span>a3</span><span>b5</span></span></span><span>. Now we know that </span><span><span>a<span>b2</span>=1</span><span>a<span>b2</span>=1</span></span>. The required difference =<span><span><span>a3</span><span>b5</span>−ab=ab(<span>a2</span><span>b4</span>−1)=ab[(a<span>b2</span><span>)2</span>−1]</span><span><span>a3</span><span>b5</span>−ab=ab(<span>a2</span><span>b4</span>−1)=ab[(a<span>b2</span><span>)2</span>−1]</span></span><span>= 0.Sufficient.</span>
Answer:
150 square meters
Step-by-step explanation:
Assuming that this field is triangular, we can multiply the two shortest sides together, and then divide by 2, because that is the formula for the area of a right triangle.
So 15 times 20 is 300
300 divided by 2 is 150
So we can estimate the area to be 150 square meters.
(Upon solving further, we realize that this is a right triangle, so our initial estimation is the exact area)
Answer:
See below.
Step-by-step explanation:
The domain and range are correct.
The relation is a function because no x value is used more than once.
