Answer:

The third graph is the graph of the function provided

Step-by-step explanation:

A simple technique that can be used to identify the graph that matches the given function is; determination of the y-intercept and then using elimination method to match the function with its graph. At the y-intercept the value of x is always zero, so we replace x with zero in the right hand side of the equation; y(x) = 2^(0+3) = 8. The graph of the function should therefore cross the y-axis at the point (0,8). Thus, the third graph is the graph of the given function.

Jasmyn is standing at the point of tangency to a wishing
timofeeve [1]

Answer:

The value of   x=17 ft.

Step-by-step explanation:

Diagram of the given scenario shown below.

Given that,

Distance from bench to Jasmyn is   PA=27ft.

Distance from bench to Willard is PB=(2x-7)ft.

From the Question,

The given wishing well is a circle and all the distance are tangent to the circle.

So, Triangle formed by these points are such as ΔPAO and ΔPBO.

Now, taking both ΔPAO and ΔPBO.

   ⇒             AO = BO                                     {Radius of circle are equal}

   ⇒             PO=PO                                     {Common side}

   ⇒          ∠PAO = ∠PBO                              {radius is always perpendicular                                                                          

                                                                           to the point of tangent }

∴            ΔPAO ≅ ΔPBO                                  {By SAS congruence theorem}

Therefore,   PA=PB         ....(1)                             {corresponding part of

                                                                           congruence triangle (CPCT)}

Thus,

   ⇒                2x-7=27                                 {from equation (1)}

   ⇒                      2x=34    

   ⇒                        x=17 ft

Hence, The value of   x=17 ft.
