Answer:

Step-by-step explanation:

1.) Given the equation 2x + 3y = 1470, to write the equation in the slope intercept form, we make y the subject of the formula.

3y = -2x + 1470

where: -2/3 is the slope and 490 is the y-intercept.

2.) To graph this equation using the slope intercept form,

i.) we plot the y-intercept point. (i.e. point (0, 490)).

ii.) we use the slope to find a second point (preferably a point on the x-axis). The slope is negative means that the line ill slope downwards from left to right. To find the point at which the line crosses the x-axis, we recall that the slope of a line is given by

i.e.

Thus, the line passes through the points, (0, 490) and (735, 0).

3.) We write the equation with a function notation as follows

The graph of the function above represents the number of wrap lunch specials sold for every given number of sandwich lunch specials sold.

4.) The graph of the function is attached. In the graph the vertical axis is the y-axis while the horizontal axis is the x-axis.

5.) Given that Sal's total profit on lunch specials for the next month is $1,593 and that the profit amounts are $2 for each sandwich and $3 for each wrap.

The gaph of the function representing the new situation is similar to the graph of the previous situation because both graphs have the same slope and a parallel to each other.

They have different y-intercept with the y-intercept of the later situation being (0, 531). Thus the graph of the later situation is above the graph of the previous situation.

6.) In the given graph the y-intercept is (0, 300) and the x-axis is (450, 0). Recall that the equation of a line with two of the point through which the line passes known is given by

Therefore, the equation of the given graph is given by

The value of the definite integral / 212x – sin(x) dx / 122x-sin(x) is
blondinia [14]

Hi there!

\boxed{= 70 + cos(12) - cos(2) \approx 71.26}

\int\limits^{12}_{2} {x-sin(x)} \, dx

We can evaluate using the power rule and trig rules:

\int x^n = \frac{x^{n+1}}{n+1}

\int x = \frac{1}{2}x^{2}

\int -sin(x) = cos(x)

Therefore:

\int\limits^{12}_{2} {x-sin(x)} \, dx = [\frac{1}{2}x^{2}+cos(x)]_{2}^{12}

Evaluate:

(\frac{1}{2}(12^{2})+cos(12)) - (\frac{1}{2}(2^2)+cos(2))\\= (72 + cos(12)) - (2 + cos(2))\\\\= 70 + cos(12) - cos(2) \approx 71.26

The cost to visit a famous tourist attraction in Russia is 442.25 Rubles. What is the cost in USD if the exchange rate is 3 USD
Lubov Fominskaja [6]

Answer:

$14.5

Step-by-step explanation:

Given data

Cost for the visit=442.25 Rubles

exchange rate

3 USD= 91.5 Rubles

but 1 USD= 91.5/3

=  30.5

Therefore if 1 USD is 30.5 Rubles

         Then   xUSD is  442.25 Rubles

cross multiply

30.5x= 442.25

divide both sides by 30.5

x= 442.25/30.5

x=14.5USD

The cost of the attraction is $14.5
