This figure is not the best, but I'll try my best here
Since BC is parallel to BE (BC is part of BE) and BA is part of BD, two sides are parallel, making two angles congruent and the triangles therefore similar.
Since BA correlates to BD (they are parallel), we can use the knowledge that BA is 7 and BD is 42 to find the scaling factor to be 42/7 =6 from ABC to DBE. Since BC correlates to BE, BC = 10, and the scaling factor is 6, BC*6=BE= 60 = height
Answer:
f(3) = 36
Step-by-step explanation:
ƒ(x) = 5x^2 − 9x + 18
Let x =3
ƒ(3) = 5(3)^2 − 9(3) + 18
= 5*9 -27 +18
= 45 -27+18
=36
Answer:
D
Step-by-step explanation:
graph it
I think the answer is 2,612.48 because if you multiply the radius, 80 by itself you get 640. Then if you multiply 640 by 3.14 and then multiply the product by 1.3 you get 2,612.48.
