Moving Company A charges a flat fee of $1200 plus $18 and hour. Company B charges $900 plus $23 an hour. After how many hours wo

sesenic [268]

We need to create two expressions, then equate them in order to find the numbers of hours.

Let X = Number of hours

Let 1200+18x = Company A (Flat Fee + Hourly Rate*Hours)

Let 900+23x = Company B

$1200+18x=900+23x\\300+18x=23x\\300=5x\\60=x$

After 60 hours, the prices will be the same

Answer:

$\int_{0}^{1}\left( - \frac{3 u^{9}}{2} + \frac{2 u^{4}}{5} + 2 \right)du=\frac{193}{100}=1.93$ .

Step-by-step explanation:

To find $\int_{0}^{1}\left( - \frac{3 u^{9}}{2} + \frac{2 u^{4}}{5} + 2 \right)du$ .

First, calculate the corresponding indefinite integral:

Integrate term by term:

$\int{\left(- \frac{3 u^{9}}{2} + \frac{2 u^{4}}{5} + 2\right)d u}} =\int{2 d u} + \int{\frac{2 u^{4}}{5} d u} - \int{\frac{3 u^{9}}{2} d u}$

Apply the constant rule $\int c\, du = c u$

$\int{2 d u}} + \int{\frac{2 u^{4}}{5} d u} - \int{\frac{3 u^{9}}{2} d u} = {\left(2 u\right)} + \int{\frac{2 u^{4}}{5} d u} - \int{\frac{3 u^{9}}{2} d u}$

Apply the constant multiple rule $\int c f{\left(u \right)}\, du = c \int f{\left(u \right)}\, du$

$2 u - {\int{\frac{3 u^{9}}{2} d u}} + \int{\frac{2 u^{4}}{5} d u} = 2 u - {\left(\frac{3}{2} \int{u^{9} d u}\right)} + \left(\frac{2}{5} \int{u^{4} d u}\right)$

Apply the power rule $\int u^{n}\, du = \frac{u^{n + 1}}{n + 1}$

$2 u - \frac{3}{2} {\int{u^{9} d u}} + \frac{2}{5} {\int{u^{4} d u}}=2 u - \frac{3}{2} {\frac{u^{1 + 9}}{1 + 9}}+ \frac{2}{5}{\frac{u^{1 + 4}}{1 + 4}}$

Therefore,

$\int{\left(- \frac{3 u^{9}}{2} + \frac{2 u^{4}}{5} + 2\right)d u} = - \frac{3 u^{10}}{20} + \frac{2 u^{5}}{25} + 2 u = \frac{u}{100} \left(- 15 u^{9} + 8 u^{4} + 200\right)$

According to the Fundamental Theorem of Calculus, $\int_a^b F(x) dx=f(b)-f(a)$ , so just evaluate the integral at the endpoints, and that's the answer.

$\left(\frac{u}{100} \left(- 15 u^{9} + 8 u^{4} + 200\right)\right)|_{\left(u=1\right)}=\frac{193}{100}$

$\left(\frac{u}{100} \left(- 15 u^{9} + 8 u^{4} + 200\right)\right)|_{\left(u=0\right)}=0$

$\int_{0}^{1}\left( - \frac{3 u^{9}}{2} + \frac{2 u^{4}}{5} + 2 \right)du=\left(\frac{u}{100} \left(- 15 u^{9} + 8 u^{4} + 200\right)\right)|_{\left(u=1\right)}-\left(\frac{u}{100} \left(- 15 u^{9} + 8 u^{4} + 200\right)\right)|_{\left(u=0\right)}=\frac{193}{100}$

Question 4 (Essay Worth 10 points)

Stella [2.4K]

Given

The attached graph

Part A: Is the graph linear or nonlinear

The attached graph has 3 different straight lines, all of which point to different directions. For a graph to be linear, such graph must have just 1 straight line. This means that the graph is nonlinear.

The attached graph is a nonlinear graph

Part B:

(i) The increasing segment

This is the segment that points in the upward direction.

In the attached graph, line segment A [i.e. from (0,0) to (2,16)] represents an upward movement of the ant.

Line segment A is the increasing segment

(ii) The decreasing segment

This is the segment that points in the downward direction.

In the attached graph, line segment C [i.e. from (4,16) to (6,0)] represents a downward movement of the ant.

Line segment C is the decreasing segment

(ii) The constant segment

This segment is represented by a vertical or a horizontal line.

In the attached graph, line segment B [i.e from (2,16) to (4,16)] represents a horizontal line.

Line segment B is the constant segment

Part C: The movement of the ant

The ant travels at a constant speed through segment A. It then rests for 2 seconds (i.e. segment B) and finally travels at a constant speed through segment C.

In addition, the 2 seconds it rests at segment B is the difference of the x-coordinates of the end points of line segment B

$Time = 4 - 2 = 2$
