Thirty-seven school buses arrived at the zoo, each carrying thirty-seven to forty-three students per bus. Estimate the number of students visiting the museum.

A: 16,000
B: 160
C: 1,600
D: 160,000

C 1,600

Step-by-step explanation:

because If you multiply 37*43 It will get you 1591 and it's asking for the estimated answer which is 1600

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

answer: none of these answers are correct only the second half is
