Answer:
The plot is attached.
Step-by-step explanation:
Plot the function y(x)=e^–0.5x sin(2x) for 100 values of x between 0 and 10. Use a 2- point-wide solid blue line for this function.
The step value for x is (10-0)/100=0.1.
Plot the function y(x)=e–0.5x cos(2x) on the same axes. Use a 3-point-wide dashed red line for this function.
The step value for x is the same as the previous function.
The plot is attached.
Answer:
Scalene triangle
Step-by-step explanation:
Coordinates of the vertices of the triangle are,
W(-7, 1), X(0, -4) and Y(2, 3)
We will use the formula to get the distance between two points.
d = ![\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28y_2-y_1%29%5E2%2B%28x_2-x_1%29%5E2%7D)
WX = ![\sqrt{(-4-1)^2+(0+7)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-4-1%29%5E2%2B%280%2B7%29%5E2%7D)
= ![\sqrt{74}](https://tex.z-dn.net/?f=%5Csqrt%7B74%7D)
WY = ![\sqrt{(1-3)^2+(-7-2)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%281-3%29%5E2%2B%28-7-2%29%5E2%7D)
= ![\sqrt{85}](https://tex.z-dn.net/?f=%5Csqrt%7B85%7D)
XY = ![\sqrt{(3+4)^2+(2-0)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%283%2B4%29%5E2%2B%282-0%29%5E2%7D)
= ![\sqrt{49+4}](https://tex.z-dn.net/?f=%5Csqrt%7B49%2B4%7D)
= ![\sqrt{53}](https://tex.z-dn.net/?f=%5Csqrt%7B53%7D)
Since, measures of all three sides of the triangle are not equal, given triangle will be a scalene triangle.
Answer:
Isaac's total bill is $84.53
Step-by-step explanation:
$37.00 + $42.00 = $79.00 < <em>b</em> (bill)
<em>b</em> + <em>t</em> (sales tax) = <em>c</em> (total cost)
(7%/100 = 0.07)
(0.07 * 79 = 5.53)
(<em>t</em> = $5.53)
$79.00 + $5.53 = $84.53
Good luck!!
