Answer:y=2x^2

Step-by-step explanation:

Given Curve passes through \left ( 0,5\right )

Also the slope of the curve at every point p is twice the Y-coordinate of p

Let the coordinate of p be\left ( x,y\right )

Therefore

\frac{\mathrm{d} y}{\mathrm{d} x}=2y

\frac{dy}{y}=2dx

Integrating both sides

\int \frac{dy}{y}=\int 2dx

\ln y=2x+c

Substituting values

\ln 5=c

\ln \frac{y}{5}=2x

y=2x^2

√- 81 doesn't result in a rational number because you can't get a negative from squaring any number. Instead you get a number with an imaginary number. 

13 - √- 81 = 13 - 9i

Y varies directly as xy equals 5 when X is 8 how do you find y when X is 9
FrozenT [24]

Given, y varies directly as x

So,

y=c\cdot x

Where c is a constant

When y equals 5 when x is 8

So,

\begin{gathered} 5=c\cdot8 \\ c=\frac{5}{8} \\  \end{gathered}

So, the relation between y and x

y=\frac{5}{8}x

now , when x = 9

Substitute with x to find y

y=\frac{5}{8}\cdot9=\frac{45}{8}

So, the answer is option 2. y = 45/8

Answer:

4/10 meters

Step-by-step explanation:

Original Length : 7/10 meters

Remaining Length after cut : 3/10 meters

amount cut off = original length - remaining length

= 7/10 - 3/10

= (7-3)/ 10

= 4/10

2/(x^2)=4/x+1<br>can any one solve this for me please
levacccp [35]
2/X^2=4/X+1                                   times by both denominators
2(x+1)=4(x^2)
2x+2=4x^2
4x^2-2x-2=0
(2x+1)(2x-2)=0
x=2x+1 or 2x-2
x=-1/2 or 1
