Answer:
y=-16^a/x^2 + 4
Step-by-step explanation:
Answer:
it's angle 1.
Reason:
vertically opposite angles are equal
1) This sequence of numbers is arithmetic, because each number is the previous one divided by two.
2) the next number in the sequence is 125/2, which is 62.5
6. The lengths of two tangent lines to a circle are equal, which can be proved using similar triangles. The perimeter is 2*(3+2+5)=10.
14. c=40 degrees, since c and the given 40 angle correspond to the same arc on the circle. b=40, since b and the given angle are alternate interior angles of two parallel lines. d=180-40-40=100 degrees. a=180-d=180-100=80 degrees.
18. a is two times the given angle according to the inscribed angle theorem. a=2*20=40. b=180-a=140. c=90 since the tangent line is perpendicular to the diameter of the circle.
19. b=85, a=95. Connect the two points on the circle near 45 degrees on the diagram. b is the sum of the two angles formed (b is the exterior angle of the small triangle), and the sum is half the central angles they correspond to, which is 360-145-45=170. So b=170/2=85, and a=180-85=95 degrees.
20. Use power of a triangle. 5*(10+5)=6(6+x), x=6.5.
Answer:
Length 100 m, width 85 m.
Step-by-step explanation:
If the perimeters are equal then the sum width + length has to be the same as 70 + 115 = 185.
The area of the given field = 115 * 70 = 8050 m^2.
Lets try length 100 and width 85 .This gives an area of 8500 so that would fit.
hope this helped pls see the comment i gave to u about my question help a friend thx :)
