Hey there! :)
Answer:
170 cm².
Step-by-step explanation:
This is an example of a composite figure, so find the areas of each shape separately:
Begin by finding the area of the smaller square. A = s²
A = 7² = 49 cm².
Find the area of the larger square:
A = 11² = 121 cm².
Add up the two areas:
49 + 121 = 170 cm².
Its the same time 80 minutes= 1 hour and 20 minutes
Hey there!
Question #1
6^2 × 6^3
6^2
= 6 × 6
= 36
6^3
= 6 × 6 × 6
= 36 × 6
= 216
36 × 216
= 7,776
6^2 × 6^3
= 6^5
• Question #1 answer: 7,776 or 6^5 either answer should work because both answers are equivalent
Question #2
√103
= 10.148892
• Question #2 answer: 10.148892
Good luck on your assignment and enjoy your day!

To test if linear model, we fit the data into a line and solve for the correlation coefficient:
The equation is
y = -1537.5x + 5466.67
and the correlation coefficient is
R² = 0.964
The model can't be exponential growth since the daily supply decreases with time. So, the data is tested if it's exponential decay. The same procedure is done the exponential equation would be linearized in the form:
y = -2816.06 lnx + 4073.57
with correlation coefficient of
R² = 0.998
Since the correlation coefficient for the exponential decay model is closer to 1, it must be the right model.
