A curve passes through the point (0, 5) and has the property that the slope of the curve at every point P is twice the y-coordin
Anit [1.1K]

Answer:

y=5e^{2x}

Step-by-step explanation:

Let (x,y) represents a point P on the curve,

So, the slope of the curve at point P = \frac{dy}{dx}

According to the question,

\frac{dy}{dx}=2y

\frac{1}{y}dy=2dx

Integrating both sides,

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

ln y=2x+ln C

ln y-ln C = 2x

ln(\frac{y}{C})=2x

\frac{y}{C}=e^{2x}

\implies y=Ce^{2x}

Since, the curve is passing through the point (0, 5),

5=Ce^{0}\implies C=5

Hence, the required equation of the curve is,

y=5e^{2x}

PLS HELPPP MEEEEEEEEE

Answer:

x= 7

B= 112

F= 68

Step-by-step explanation:

to find x we set up an equation, (16x)=(4x+84). They are alternate interior angles which are always equal.

calculate it and you'll find x=7.

B and the angle 4x+84 are equal because they are vertical angles, to find it we just put 7 instead of x into 4x+84.

4(7)+84=112

angle f is supplementary to 16x. 16x is also 112 because they are equal, so its just 180-112=68
