Answer:

Option C is true.

Step-by-step explanation:

See the attached diagram.

Since MN is a diameter of the circle at P, so it will always make a right angle at a point on the circumference of the circle.

Therefore, ∠ MLN = 90° as L is a point on the circumference.

Now, given that LM = 2x and LN = 3x, then we have to find MN.

So, applying Pythagoras Theorem, MN² = LM² + LN²

⇒ MN² = 4x² + 9x² = 13x²

⇒ MN = x√13

Therefore, option C is true. (Answer)

4(5x-6)=2(8x+10) how to solve

Pavel [41]

Hello! :)

Answer:

$\boxed{X=11}$

*The answer must have a POSITIVE sign!*

Step-by-step explanation:

Expand with distributive property: a(b+c)=ab+ac

4*5=20

6*4=24

20x-24

2*8=16

2*10=20

16x+20

20x-24=16x+20

First, you add by 24 both sides of an equation.

20x-24+24=16x+20+24

20x=16x+44

You subtract by 16x both sides of an equation.

20x-16x=16x+44-16x

4x=44

Then, you divide by 4 both sides of an equation.

4x/4=44/4

Divide by the numbers from left to right.

44/4=11

<u><em>X=11 is the final answer</em></u>

Hope this helps!

Have a nice day! :)

Consider a sequence given by the formula f(n) = 1 / 3 ^ n−1 starting with n = 1. Generate the first 5 terms of the

denpristay [2]

Answer:

Step-by-step explanation:

According to the formula we need to start from n = 1. So the first 5 terms of the sequence, will have the following values of n: 1,2,3,4,5

Now, we need to replace the values of n into the formula to get all the terms.

f(1) = 1/3 ^ 1-1 = 1/3^0 = 1.

This is because any number elevated to zero is always the unit, in this case, 1.

f(2) = 1/3 ^2-1 = 1/3 ^1 = 1/3

This, because any number elevated to 1, is always the same initial number.

f(3) = 1/3 ^3-1 = 1/3 ^2 = 1/9.

Because when the exponent is elevating a fraction number, the power goes to both numbers (numerator and denominator)

f(4) = 1/3 ^4-1 = 1/3 ^3 = 1/27.

f(5) = 1/3 ^5-1 = 1/3 ^4 = 1/81.
