Find (a) the slope of the curve at the given point P, and (b) an equation of the tangent line at P: y = 9x^2 + 5 ; P (2,41)

Flauer [41]

Answer:

(a) 36

(b) y = 36x-31

Step-by-step explanation:

(a) dy/dx = 18x

slope of tangent at (2, 41) = 18(2)

= 36

(b) using y-y1 = m(x-x1)

y-41 = 36(x-2)

y = 36x-31

The area of a pentagon increased by 27 is the same as four times the area of the pentagon, minus 15. what is the area of the pen

Basile [38]

Set up an algebraic equation. This is what it looks like based on what the question tells you:

Let a = area of pentagon
a+27 = 4a-15
3a-15 = 27
3a = 42
a = 14

What is the distance of the line?<br> Remember the distance formula is (23 - 23) + (42 -

vivado [14]

Answer:

<em>The distance of the line is 10.82</em>

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x1,y1) and B(x2,y2), the distance between them is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The graph clearly shows the points (-5,4) (4,-2), thus the distance is:

$d=\sqrt{(4-(-5))^2+(-2-4)^2}=\sqrt{9^2+(-6)^2}$

$d=\sqrt{81+36}=\sqrt{117}=10.82$

The distance of the line is 10.82
