In what ratio does the points (2,-5) divide the line segment A(-3,5) and B(4,-9)

Strike441 [17]

Your question has been heard loud and clear.

let the ratio be m:n

From section formula

(-3n + 4m)/(m+n) = 2

-3n + 4m = 2m+2n

5n = 2m

m/n = 5/2

m:n = 5:2

Is y = 3x2 + 2x2 + x a polynomial?

Paha777 [63]

No, it’s not a polynomial because it has three terms and a polynomial has more than three terms. It would be a trinomial.

Find the surface area of the following figure

Julli [10]

Answer:

Step-by-step explanation:

We have:

two trapezoids with bases 15ft and 7ft and height 5ft.

four rectangles 5ft × 11ft, 15ft × 11ft, 9.4ft × 11ft and 7ft × 11ft.

The formula of an area of a trapezoid:

$A_t=\dfrac{b_1+b_2}{2}\cdot h$

b₁, b₂ - bases

h - height

Substitute:

$A_t=\dfrac{15+7}{2}\cdot5=\dfrac{22}{2}\cdot5=(11)(5)=55\ ft^2$

The formula of an area of a rectangle:

$A_r=lw$

l - length

w - width

The dimensions of rectangle l × w

Subtitute:

$A_1=(5)(11)=55\ ft^2\\\\A_2=(15)(11)=165\ ft^2\\\\A_3=(9.4)(11)=103.4\ ft^2\\\\A_4=(7)(11)=77\ ft^2$

The surface area of the figure:

[tex]S.A.=2A_t+A_1+A_2+A_3+A_4\\\\S.A.=2(55)+55+165+103.4+77=510.4\ ft^2[/text]
