Step-by-step explanation:
No trapezoid is attached; so, I will solve on a general note
The area of a trapezoid is:
![Area = \frac{1}{2}(Sum\ of\ parallel\ sides) * Height](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28Sum%5C%20of%5C%20parallel%5C%20sides%29%20%2A%20Height)
Using the attached image as a point of reference;
The parallel sides are: AD (6cm) and BD (12cm)
The height is 4cm
So, the area is:
![Area = \frac{1}{2} * (6cm + 12cm) * 4cm](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20%286cm%20%2B%2012cm%29%20%2A%204cm)
![Area = 18cm * 2cm](https://tex.z-dn.net/?f=Area%20%3D%2018cm%20%2A%202cm)
![Area = 36cm^2](https://tex.z-dn.net/?f=Area%20%3D%2036cm%5E2)
Answer:
5 days
Step-by-step explanation:
Put the given number in the formula and solve for x.
2065500 = 8500·3^x
243 = 3^x . . . . . . . . . . . divide by 8500
log(243) = x·log(3) . . . take logarithms
log(243)/log(3) = x = 5 . . . . divide by the coefficient of x
After 5 days, the number of bacteria in culture will be 2,065,500.
Answer: y=1x+4
Step-by-step explanation: the b (y-intercept) is 4 and when you go up 1/1 (1) it crosses the lines
