A rectangular playground has a width of 54 feet and a length of 81 feet. Martina makes a scale model of the playground using a scale of 1 in:3 ft. What are the dimensions of Martina’s scale model?

72 and 108

Step-by-step explanation:

540/30= 18 *4 = 72

and

810/30= 27*4=108

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
