One of the students in the class scored 100 on the midterm but got overconfident, slacked off, and scored only 15 on the final e

xam. No other student in the class "achieved" such a dramatic turnaround. If the instructor decides not to include this student’s scores when constructing a new regression model, will the slope of the new line increase or decrease?

If dy/dx = x(y-1), find the equation of the tangent line at x=-2 with f(-2)=3
Lapatulllka [165]

Answer:

The equation of the tangent line passing through the point (-2,3) is

 4 x + y +5 =0

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the slope of the tangent</em>

<em>              </em>m = \frac{dy}{dx} = x(y-1)<em></em>

<em>              m = -2( 3-1) = -4</em>

<em>Given point x = -2</em>

<em>          y = f(-2) =3</em>

<em>∴The given point ( x₁ , y₁) = ( -2 ,3)</em>

<u><em>Step(ii):-</em></u>

The equation of the tangent line passing through the point (-2,3)

y - y_{1} = m(x-x_{1} )

y -3 = -4(x-(-2))

y -3 = -4( x+2)

y-3 = -4x -8

4x + y -3+8=0

4x +y +5=0

<u><em>Step(iii):-</em></u>

<em>The equation of the tangent line passing through the point (-2,3) is</em>

<em>   4 x + y +5 =0</em>

<em></em>

Find the lateral area of this pyramid whose base is a regular hexagon with a side length of 3cm and whose slant height is 12cm.
sergeinik [125]

i think you do it by like

12squared - 1.5 squared = A Squared

you do this to get the height

so

144- 2.25 = 141.75 then you square root it which equals 11.90

11.90×3÷2 = 17.85

17.85×6= 107. 15

im not sure

Work out the area of the shaded shape
liberstina [14]

Answer:

62 meters.

Step-by-step explanation:

Seperate the figure into three squares.

Then, find the areas of those squares using the area formula.

A=lw

A=4*4=16

A=3*14=42

A=1*4=4

Add up all those numbers, and you have the area.

16+42+4=62 meters.
