Answer:

A. Convex pentagon

Step-by-step explanation:

It has 5 sides, so it is a pentagon.

<em>A convex polygon is a polygon with all interior angles smaller than 180°.</em>

We know this is true for the given polygon.

Correct choice is A.

Use integration by parts to find the integrals in Exercise.<br> ∫(x+6)ex dx.

skelet666 [1.2K]

Answer:

$xe^x+5e^x$

Step-by-step explanation:

We have given integral $\int (x+6)e^xdx$

$\int (xe^x+6e^x)dx$

$\int (I_1+I_2)dx$ , here $I_1=xe^x$ and $I_2=6e^x$

Now first integrate $I_1$

So $I_1=\int xe^x$

Integrating by part

$I_1=x\int e^x-\int e^x\frac{d}{dx}x$

$I_1=x e^x- e^x$

$I_2=6\int e^x=6e^x$

So $I=I_1+I_2=xe^x-e^x+6e^x=xe^x+5e^x$

Use the formula . Find t for r = 33.2 m/h and d = 375.16 m.

Butoxors [25]

$\boxed{t=11.3h}$

<h2>Explanation:</h2><h2></h2>

In this problem we have the following data:

$r:speed \\ \\ d:distance \\ \\ t:time \\ \\ \\ r=33.2m/h \\ \\ d=375.16m \\ \\ \\ So \ our \ goal \ is \ to \ find \ t$

Speed, time and distance are related with the following formula:

$r=\frac{d}{t} \\ \\ \\ Solving \ for \ t: \\ \\ t=\frac{d}{r} \\ \\ t=\frac{375.16}{33.2} \\ \\ \boxed{t=11.3h}$
