Answer:
A). Surface area = 222 cm²
Volume = 180 cm³
B). Surface area = 375 cm²
Volume = 360 cm³
C). % increase in surface area = 67.57%
% increase in volume = 100%
Step-by-step explanation:
In the figure attached base of a prism has been given.
A). Surface area of the prism = (Perimeter of the base of the prism) × height + 2(area of the base)
Perimeter of the base = 5 + 3 + 2 + 2 + 2 + 3 + 5 + 8
= 30
Area of the base = 8×5 - 2×2 = 36 cm²
Surface area of the prism = 30×5 + 2×(36)= 222 cm²
Volume of the prism = volume of the bigger prism - volume of the smaller prism cut off
= 8×5×5 - 2×2×5
= 200 - 20
= 180 cm³
B). Surface area of the prism if it's height is 10 cm,
Surface area = 30×10 + 2×(36) = 372 cm²
Volume of the prism = 8×5×10 - 2×2×10
= 400 - 40
= 360 cm³
C). Increase in surface area = 372 - 222 = 150 cm²
% increase in the surface area =
= 67.57%
Increase in volume = 360 - 180 = 180 cm³
% increase in volume =
= 100%
Answer:
2.56
Step-by-step explanation:
1.6^2 = 1.6 * 1.6 = 2.56

➴ The correct answer is B. the temperature in F on a summer day
B is correct because temperatures in the summer (in Fahrenheit) are high and positive. All the other answer choices are negative numbers.

Answer:
Logarithmic
Step-by-step explanation:
It's literally a logarithmic function because it includes "log" which is short for logarithmic.
Answer:
A
Step-by-step explanation:
The solution to f(x) = g(x) occurs where the two graphs cross. That's at the point (-2, -1).
