Answer:39+8r

Step-by-step explanation:

To find the answer you have to distribute the problem. To do this you do (4×5) and (4×8r). Whenever you do this you get 20+8r+19. You then need to add common factors in which for this problem would be 20 and 19. Whenever you add 20+19 you get 39 and then since the 8 has a r on the side you don't do anything with it so you just put 39+8r and that would be your answer

Write an exponential equation in the form y = ab* whose graph passes through points (2, 18) and (5, 60.75).
DochEvi [55]

Let y=ab^x, as described in the problem statement. Plugging in x=2 and x=5 gives us the equations 18=ab^2 and 60.75=ab^5. Since a,b are nonzero, we divide the second equation by the first to get \frac{27}{8}=b^3, which means that b=\frac{3}{2}, after taking the cube root. Plugging this value for b into the first equation, we now have 18=a(3/2)^2=\frac{9a}{4}. Solving gives a=8, and our desired exponential equation is \boxed{y=8\left(\frac{3}{2}\right)^x}.

Jenny wants to paint the ceiling of her restaurant. the ceiling is in the shape of a square. its side lengths are 44 feet. suppo
inysia [295]
First we need to find the square footage of her ceiling, since it's a square just multiply the side by the side: 44•44=1936. Now divide the square feet by how many feet each can can paint: 1936/242=8. Jenny would need exactly 8 cans of paint to paint her ceiling :)
