Differential equations <br> dy/dx = e^x-y

MA_775_DIABLO [31]

$\frac{dy}{dx}=e^{x-y} \\ \\ \frac{dy}{dx}=\frac{e^{x}}{e^{y}} \\ \\ e^{y} \text{ } dy=e^{x} \text{ } dx \\ \\ \int e^{y} \text{ } dy=\int e^{x} \text{ } dx \\ \\ e^{y}=e^{x}+C \\ \\ \boxed{y=\ln \left(e^{x}+C \right)}$

Geometry! Please help. See image. BRAINLIEST!

Answer:

B. $r_{x-axis}(x,y) \circ R_0,90\degree)$

Step-by-step explanation:

The vertices of triangle ABC have coordinates A(5,2) B(2,4) and C(2,1).

The mapping for reflection in the x-axis is

$(x,y)\to (x,-y)$

When we reflect triangle ABC in the x-axis, we obtain

A1(5,-2) B1(2,-4) and C1(2,-1).

The mapping for 90 degrees clockwise rotation about the origin is

$(x,y)\to (y,-x)$

When we rotate the resulting triangle through 90 degrees clockwise above the origin, we obtain;

A2(-2,-5) B2(-4,-2) and C2(-1,-2).

The vertices of triangle A''B''C'' also have coordinates A''(-2,-5) B''(-4,-2) and C''(-1,-2).

Hence the rule that describes the composition of transformation that maps ABC to A''B''C'' is

$R_0,90\degree \circ r_{x-axis}(x,y)$

The correct choice is B.

Determine the area of a parallelogram if<br> its base is 16 cm and its height is 7 cm.

ella [17]

<h3>Answer: 112 square cm</h3>

=====================================

Work Shown:

area = base*height

area = 16*7

area = 112 square cm

----------------

Extra info (optional section):

The area formula for a parallelogram is the same as the formula for a rectangle. Imagine tilting a rectangle so that it's slanted. The area has not changed.

Or another thing to imagine is that let's say we had a stack of 2 by 4s. If the stack is perfectly vertical, aka forming a rectangle, then we can nudge the beams so that we can form a slanted parallelogram instead. Both configurations involve the same amount of wood, and therefore would lead to the same frontal surface area.
