A bridge on a river is modeled by the equation h = -0.2d2 + 2.25d, where h is the height and d is the horizontal distance. For c
icang [17]
The answer is 2.2108
Solution:
first equation:
h = -0.2d² + 2.25d-d + 6h = 21.77
2nd equation:-d + 6h = 21.77d = 6h - 21.77
Then substitute:h = -0.2(6h - 21.77)² + 2.25(6h - 21.77)h = 3.9968
Answer:d = 2.2108

Consider the differential equation: dy/dx = (y-2)(x^2+1)
Klio2033 [76]

Answer:

6

Step-by-step explanation:

Given,

\dfrac{dy}{dx}=(y-2)(x^2+1) ...(i)

Differentiating w.r. to x.

\dfrac{d^2y}{dx^2}= (y-2)(2x)+ (x^2+1)\dfrac{dy}{dx}

From equation (1)

\dfrac{d^2y}{dx^2}= (y-2)(2x)+ (x^2+1)^2(y-2)

Now, at the point (1,3)

\dfrac{d^2y}{dx^2}= (3-2)(2\times 1)+ (1^2+1)^2(3-2)

\dfrac{d^2y}{dx^2}=6

Graph 3x + 4y = -10
cricket20 [7]
First, isolate y on one side to find some information about the graph. 

3x+4y=-10 
4y=-10-3x
y=(-10-3x)/4 

Now find out the x and y intercepts of this equation;

(0)=(-10-3x)/4 
4x0=-10-3x 
0=-10-3x 
3x=-10 
x=-10/3 or -3.3333 (x-intercept) 

y=(-10-3(0))/4
4y=-10 
y=-10/4 or -5/2 = -2.5 (y-intercept) 

Plot these points onto your graph and connect the lines. 

I have attached a graph below, I'm sorry I couldn't do it on paper. 

Hope I helped :)
