Derivative of 2ln(secx)

1 answer:

5 0

2tan(x)

i. take the 2 out
ii. derivative of acos is -sin
iii. derivative of In is -ve inverse

so we have 2 times sin(x)/cos(x) hence 2tan(x)

Find the measure of angle Y

Musya8 [376]

Answer:

∠y=60°

Step-by-step explanation:

Question says to find the measure of the angle Y.

We have been given a picture of triangle XYZ. All angles are marked with same sign so that indicates that all three angles are equal.

∠x = ∠y = ∠z...(i)

We know that sum of all three angles of the triangle is always 180°.

So we can write:

∠x+∠y+∠z=180°

∠y+∠y+∠y=180° {using equation (i) }

3∠y=180°

divide both side by 3

∠y=60°

Hence final answer is the measure of angle y is 60 degree.

koban [17]

Answer:

$7,333.33 (approximately)

Step-by-step explanation:

First step: $10^{12}$ = 1,000,000,000,000

Second step: 2.2 x 1,000,000,000,000 = 2,200,000,000,000

Third step: 2,200,000,000,000 ÷ 300,000,000 = 7,333.333333333333

dalvyx [7]

Answer:

9. x = 7

10. x = 12

Step-by-step explanation:

Assume the two lines are parallel.

9. The corresponding angles are congruent.

9x - 3 = 7x + 11

2x = 14

x = 7

10. The alternate interior angles are congruent.

5x - 20 = 2x + 16

3x = 36

x = 12
