Answer:

m∠PQR = 133

Step-by-step explanation:

∠PQR and ∠RQS are supplementary angles, meaning they have a sum of 180°.

3x - 5 + x + 1 = 180

4x - 4 = 180

4x = 184

x = 46

Now we simply substitute 46 in for x:

3(46) - 5 = 133

Which lines are the directrices of the ellipse?
algol [13]

The lines that are the directrices of the ellipse is B. x = −3.25 and x = 9.25.

<h3>How to calculate the ellipse? </h3>

From the information given, the equation of parabola will be:

= (x - 3)²/5² + (y - 2)²/3² = 1

Hence, h = 3, k = 2, a = 5, b = 3

e = ✓1 - ✓3²/5²

E = 4/5 = 0.8

The directix will be:

x = 3 + 5/0.8

x = 9.25

x = 3 - 5/0.8

x = -3.25

Therefore, lines that are the directrices of the ellipse is x = −3.25 and x = 9.25.

Please Answer Attachment Below Thanks
docker41 [41]

Answer:

Step-by-step explanation:

The interior angles of a heptagon add up to 5*180 = 900

So

x + 143 + 116 + 135 + 135 + 116 + 155 = 900     Add up the known angles

x + 800 = 900                                                   Subtract 800 from both sides

x + 800 - 800 = 900 - 800                              Combine

x = 100

If f(x) = f(x)g(x), where f and g have derivatives of all orders, show that f'' = f ''g + 2f 'g' + fg''.
Nadya [2.5K]
Differentiating once, we have

f'(x)=f'(x)g(x)+f(x)g'(x)

Differentiating again,

f''(x)=f''(x)g(x)+f'(x)g'(x)+f'(x)g'(x)+f(x)g''(x)
f''(x)=f''(x)g(x)+2f'(x)g'(x)+f(x)g''(x)

as needed.
