It is D

528 X 65 -85 =34,235

528 X 65 -75 = 34.245

34,235<34,245

Answer:

I = 1.47001

Step-by-step explanation:

we have the function

$f(x,y)=sin(x^2y^2)\\$

In polar coordinates we have

$x=rcos\theta\\y=rsin\theta$

and dA is given by

$dA=rdrd\theta$

Hence, the integral that we have to solve is

$I=\int \limt_2^4 \int \limit_0^{\pi /2}sin(r^4cos^2\theta sin^2\theta)rdrd\theta$

This integral can be solved in a convenient program of your choice (it is very difficult to solve in an analytical way, I use Wolfram Alpha on line)

I = 1.47001

Hope this helps!!!

Answer:

£ 21552.13

Step-by-step explanation:

P= £18790

r =4.9% = $\frac{4.9}{100}=0.049$

t = 3 years

I = Prt

I = 18790 * 0.049 * 3

=£ 2762.13

After 3 years , the amount in Dan's account = 18790 + 2762.13

= £ 21552.13

Which of the following graphs represents the equation y+2=3(x-1)

Arturiano [62]

For this case we have the following equation, in a linear way:

$y + 2 = 3 (x-1)$

This expression can be written in the form $y = mx + b$

Where "m" is the slope and "b" is the cut point with the y axis.

Rewriting the given expression we have:

$y + 2 = 3x-3\\y = 3x-3-2\\y = 3x-5$

Thus, the slope is 3 and the cut point is -5.

To graph, we must find two points through which the line passes, so, we perform the following steps:

Step 1:

We do $x = 0$

$y = 3 (0) -5\\y = 0-5\\y = -5$

Thus, the point $(x1, y1) = (0, -5)$

Step 2:

We do $y = 0$

$0 = 3x-5\\5 = 3x$

$x =\frac{5}{3}$

Thus, the point $(x2, y2) = (\frac{5}{3},0)$
