Beth enlarged the triangle below by a scale of 5. she found the area of the enlarged triangle. her work is shown below. what was beth's error? she should have divided by 5. she should have divided by. she should have multiplied by 5. she should have multiplied

sine

step-by-step explanation:

0,0

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

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it
