Answer:

E and I are alternate interior angles, therefore are congruent

m∠E = m∠I = 60°

E and F are complementary, therefore add to 90°

m∠F = 90° - 60° = 30°

H and I supplementary, therefore add to 180°

m∠H = 180° - 60° = 120°

Solve for e. T=e29 e=±3T√T e=±3T e=±3T√ e=±9T√

Anon25 [30]

Answer:

option (3) is correct.

$e= \pm 3\sqrt{T}$

Step-by-step explanation:

Given $T=\frac{e^2}{9}$

We have to solve for e.

Consider the given statement,

$T=\frac{e^2}{9}$

Cross multiply, we get,

$\Rightarrow 9T={e^2}$

Taking square root both sides , we get,

$\Rightarrow \sqrt{9T}=e$

We know square root of 9 is 3.

$\Rightarrow \pm 3\sqrt{T}=e$

Thus, option (3) is correct.

$e= \pm 3\sqrt{T}$

The number 66 is increased to 72. What is the percentage by which the number was increased, to the nearest tenth of a percent?

Lunna [17]

Answer:

The increase is 9.1%

Step-by-step explanation:

Step 1: Make an equation

$66 * x = 72$

$66x = 72$

Step 2: Divide both sides by 66

$66x / 66 = 72 / 66$

$x = 1.09090$

Step 3: Find the increased

$1 - 1.09090$

$0.091 * 100$

9.1%

Answer: The increase is 9.1%

Find the slope of the line that passes through (6, 2) and (10,3).

weeeeeb [17]

Answer:

Step-by-step explanation:

Firstly,you must divide (6,2) to (x¹y¹).After that,you must divide (10,3) to (x²y²).Then you must substract (y²-y¹,x²-x¹).It will be like this (3-2,10-6).So the correct answer is 1,4 (D).Hope you will understand!

Find the first partial derivatives of the function. (sn = x1 + 2x2 + ... + nxn; i = 1, ..., n. give your answer only in terms of

liq [111]

Answer:

∂u/∂xi = i·cos(sn)

Step-by-step explanation:

For u = sin(v), the partial derivative of u with respect to xi is ...

∂u/∂xi = cos(v)·∂v/xi

In this case, v=sn, and ∂sn/∂xi = i, so the derivatives of interest are ...

∂u/∂xi = i·cos(sn)
