Equation and work : x^2 + 5x - 104 = 0
+104
x^2 + 5x = 104
Add the x's together
6x^2 = 104
6 Squared is 36
36x=104
Divide 104 by 36
x= about 2.8 with the decimal repeating
Rounded to the nearest tenth the answer is 2.9, and rounded to the nearest whole number the answer would be 3.
Hope this helps!

Solve the differential equation dy/dx= y^2/x^3 for y=f(x) with the condition y(1) = 1.
Gennadij [26K]
We will use seperation of variables

tmes both sies by 1/(y^2)
times both sides by dx

we get

1/(y^2)dy=1/(x^3)dx
integrate both sides
-1/y=1/(2x^2)+c

initial condition, (1,1)
-1/1=1/(2(1^2))+c
-1=1/2+c
-3/2=c


-1/y=1/(2x^2)-3/2
solve for y
-1=y(1/(2x^2)-3/2)
y=-1/(1/2x^2-3/2)
y= \frac{2x^2}{3x^2-1}

A company makes two models of television.
VLD [36.1K]

Answer:

16/25

Step-by-step explanation:

length of screen B=44*(5/4)=55cm

and its width=32*(5/4)=40cm

so, screen B had dimensions 55cm by 40 cm

screen A area=44*32 cm sqr

screen B area=55*40 cm sqr

so, model A screen area/model B screen area

=(44*32)/(55*40)

=16/25
