Answer:

p, because Triangle ABC is similar to triangle EDC

Step-by-step explanation:

<h3>Given</h3>

The triangles have a common vertex C
m∠ABC = 70°
m∠BAC = p
m∠CDE = 70°
m∠CED = ?

<h3>Solution</h3>

As C is common vertex, the angles BCA and DCE are vertical angles and therefore have same measure

Sum of angles of ABCΔ:

70° + p + ∠C = 180°

Sum of angles of ΔEDC:

70° + ∠CED + ∠C = 180°

Comparing the sums above we get:

∠CED = p

Correct option is the last one:

p, because Triangle ABC is similar to triangle EDC

Find gradient xe^y + 4 ln y = x² at (1, 1)

cricket20 [7]

$xe^y+4\ln y=x^2$

Differentiate both sides with respect to x, assuming y = y(x).

$\dfrac{\mathrm d(xe^y+4\ln y)}{\mathrm dx}=\dfrac{\mathrm d(x^2)}{\mathrm dx}$

$\dfrac{\mathrm d(xe^y)}{\mathrm dx}+\dfrac{\mathrm d(4\ln y)}{\mathrm dx}=2x$

$\dfrac{\mathrm d(x)}{\mathrm dx}e^y+x\dfrac{\mathrm d(e^y)}{\mathrm dx}+\dfrac4y\dfrac{\mathrm dy}{\mathrm dx}=2x$

$e^y+xe^y\dfrac{\mathrm dy}{\mathrm dx}+\dfrac4y\dfrac{\mathrm dy}{\mathrm dx}=2x$

Solve for dy/dx :

$e^y+\left(xe^y+\dfrac4y\right)\dfrac{\mathrm dy}{\mathrm dx}=2x$

$\left(xe^y+\dfrac4y\right)\dfrac{\mathrm dy}{\mathrm dx}=2x-e^y$

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{2x-e^y}{xe^y+\frac4y}$

If y ≠ 0, we can write

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{2xy-ye^y}{xye^y+4}$

At the point (1, 1), the derivative is

$\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{x=1,y=1}=\boxed{\dfrac{2-e}{e+4}}$

Drag a reason to each box to complete this proof. If 12=13x+5 , then x = 21.

Ainat [17]

I think the answers are:

Statement Reason
12=13x+5 Given
7=13x Subtraction Property of Equality
21 = x Multiplication Property of Equality
x = 21 Symmetric Property of Equality

By the way, I'm doing the same exam for Geometry as well. There's a lot of proof questions on there which I'm not good at doing for the reasoning part. If you finish the exam before I do, maybe you can message me what the answers are for some of the questions on there so I know if my answers for the questions are incorrect or not.

Besides that, hope the answer above is correct for you.
