The coordinates of point r(-8,0).
<h3>What is midpoint formula in coordinate geometry?</h3>
The coordinates of the point r(x,y) which divides the line segment joining the points p(
,
) and q(
,
) internally in the ratio :
are
Given that,
Two end points on the line q(-14,0) and s(2,0). point r(x,y) is the partition of the line segment from q to s in a ratio 3:5
= 3 and = 5
By using the midpoint formula
Hence, The coordinates of point r(-8,0).

The x-value corresponds to a y-value of 1 is π
Step-by-step explanation:
The given is:
- y = - cos x
- y = 1
- 0 < x < 2π
We need to find x when y is 1
∵ y = - cos x
∵ y = 1
∴ 1 = - cos x
- Multiply both sides by -1
∴ -1 = cos x
- Switch the two sides
∴ cos x = -1
- Use the inverse of cos to find x
∴ x = 
∵ cos(π) = -1
∴ x = π
The x-value corresponds to a y-value of 1 is π
Look to the attached graph for more understand
<em>The graph of y = 1 intersects the graph of y = - cos x at x = π from 0 to 2π</em>

Answer:
The model and the actual building would be similar
Step-by-step explanation:
Answer:
The triangles are similar
Step-by-step explanation:
We are given and two angles so by default we know the third angle. We know the three angles are the same, so the triangles are similar by AAA. We do not about conqruency without a side length.
