Surface area of the pyramid= 4*(area of the triangle) + area of the square
Area of the triangle = (1/2)*base*height=(1/2)*5*5= 25/2 in²
Area of the square = 5*5 =25 in²
Surface area of the pyramid = 4*(25/2) + 25=2*25 + 25=75 in²
Approaches 0 as x approaches infinity or C
Triangle area= b*h/2
Plug in the values:
25*8/2
200/2
100
Final answer: 100 ft^2
Answer:
Slope = 0.08 dollars per minutes.
Step-by-step explanation:
Carla pays $20 per month for her phone service, plus $0.08 for each long-distance minute used.
Therefore, if Carla talks for m minutes in the long-distance call, then the situation can be modeled by the equation
C = 20 + 0.08m ............ (1), where C is the total cost for her phone service per month.
Here, 20 is the fixed price and 0.08m is the variable price for her phone charges.
This equation (1) represents a straight line with y-intercept as 20 and the slope as 0.08, where m plotted along x-axis and C is plotted along the y-axis. (Answer)
