(3x + 2y^2)(9x^2 - 6xy^2 + 4y^4)
A heart only has one line of symmetry-down the middle-
7,800 in expanded form would be 7,000 + 800.
Hope this helps!
The object's maximum height is the same as the y-coordinate of the vertex.To find that, first, finds the x- coordinate(t).You can find it by:
first identifying a,b and c.Multiply the b by negative 1 or simply change its sign and divide it by 2a.Afterward, plug the answer in the equation to find y, your answer.
(ax+bx²+c=-16t²+64t+80). Therefore, a=-6, b= 64 and c=80
-64/2(-16)=-64/-32=2
-16(2)²+64(2)+80=144 ft
So the maximum height of the object, when launched 64ft/sec from a platform that is 80 ft high, is 144 ft
Hope this helps(there are other methods)
Answer:
-27
Step-by-step explanation:
Multiply -3 times 9 to get -27. Check it by dividing -27 by -3. If you get 9 your correct.
