The diagram shows a homemade car being pushed with a force of 25 N. Force - 25 N
Motion
of car
The force causes the car to move at a constant speed of 3 m/s. What will happen if the force is changed to 35 N?

step-by-step explanation:

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

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
