simplification :

  • \sqrt{ - 121}

  • \sqrt{ {i}^{2} \times  11 \times 11}

  • 11i

therefore, correct option is B

The answer is B. 11i. You move 11 to the left of i because of I · 11 and so you switch it.

Need help. Anything is appreciated!
Lynna [10]

First attatchment:

1. Given

2. Definition of a parrallelogram

3. Transitive

4. Parts of line FE and AB

5. Opposite sides of a parallelogram are parallel.

You want to switch those last two because you're using what you want to prove to prove something before you've proved it, which is fallacious.

SECOND ATTATCHMENT:

In a parallelogram, opposite angles are equal and same side interior angles add up to 180.We have 2x+60+x+30=180 which means 3x+90=180 so x=30.Since x is 30 then angle to is 60 which means that angle A is 60, not 30.

THIRD ATTATCHMENT:

This is just the triangle midpoint theorem. SM is parallel to RU not VS.

FOURTH ATTATCHMENT:

Angle X and angle F are corresponding angles, so they are actually equal. You want Angle G and Angle F becuase they are same side interior angles.

FIFTH ATTATCHMENT:

this is correct

At what point of the curve y = cosh(x) does the tangent have slope 3?
Rus_ich [418]

Answer:

(1.82, 3.17)

Step-by-step explanation:

Given the curve:

y = cosh(x)

we need that the tangent has slope 3. The tangent of a curve in a given point is found with its derivative.

dy/dx = sinh(x) = 3

From the plot of sinh(x), we get:

x ≈ 1.82

Replacing into cosh(x), we get:

y = cosh(1.82) ≈ 3.17

Then, at point (1.82, 3.17) the tangent is 3
