Your The barrel of a rifle has a length of .968m. A bullet leaves the muzzle of
a rifle with a speed of 581m/s. What is the acceleration of the bullet
while in the barrel? A bullet in a rifle barrel does not have constant
acceleration, but constant acceleration is to be assumed for this problem.

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

the answer is d

step-by-step explanation:

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

part a: 1.08

part b: 27.59
