Answer:

180 units

Step-by-step explanation:

The perimeter of ∆XYV is ...

Pxyv = XY +YV +VX

Pxyv = 29 +31 +40 = 100

The triangles are similar, so the scale factor from ∆XYV to ∆XZW applies to the perimeter. That scale factor is ...

WX/VX = (32+40)/40 = 1.8

Then ...

Pxzw = 1.8 × Pxyv = 1.8 × 100

Pxzw = 180 . . . units

Use the graphs below to help you answer the question. Which of the following is the best approximation to a solution of the equa

brilliants [131]

Answer:

2 is the correct option.

Step-by-step explanation:

We have the equation $e^x=4x+1$ .

We will plot the graphs of the function $e^x$ and $4x+1$ .

Then, the intersection points of both the graph will be the solution of the equation $e^x=4x+1$ .

From the graphs, we see that,

The intersection points of the graphs are (0,1) and (2.337,10.347).

The solution of the equation is the value of 'x' co-ordinate where they intersect.

So, we get, x = 2 is the correct option.
