Answer:
(3x + 8y)(3x - 8y)
Step-by-step explanation:
this is the difference of 2 perfect squares.
9x2 - 64y2
(3x + 8y)(3x - 8y)
We will use <span>y-y1=m(x-x1), where m= f '(x)= 4x^3e^-x - x^4e^-x, f ' (1) =3e^-1
</span>f (1) =4e^-1
so the equation of tangent line tothe curve at the point <span>(1,1/e) is
y= </span>3e^-1(x-1) + 4e^-1, or y= 3e^-1(x)) + e^-1,

Answer:
572.40
Step-by-step explanation:
First find the tax
540 * .06 = 32.4
Add this to the original cost
540+32.4 =572.40
The x-intercept of the line 3x - 5y = 7 is at point ( 7/3, 0 ).
<h3>What is the x-intercept of the line?</h3>
Given the function;
X-intercept occurs on the graph when y=0. Hence, to determine x-intercept, we substitute in 0 for y and solve for x.
3x - 5y = 7
3x - 5(0) = 7
3x - 0 = 7
3x = 7
x = 7/3
Hence, we have a point ( 7/3, 0 ).
The x-intercept of the line 3x - 5y = 7 is at point ( 7/3, 0 ).
