What is the domain of the function graphed below? 5 4 2 -6 -5 -3 -2 3 7 2 0-1( 4 5 6 4-1)( (-2, infty) \ -2,4\ [7, infty) \ - infty,4) and [-2,0] and (7, infty) Please help!

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

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

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)

55 degrees because 55+55=110 degrees
