Answer:

7.5

Step-by-step explanation:

We are given information that the two triangles are similar and we want to work out the length of "t" . Since these 2 triangles are similar, it means that a scale factor is used to enlarge the sides, we can work out the scale by dividing QP by LJ and RP by KJ so,

QP ÷ JK = 25 ÷ 5 = 5

RP ÷ JL = 22.5 ÷ 4.5 = 5

So we can see the scale factor is 5, now all we need to do is multiply the scale factor by 1.5 to find the value of t

1.5 × 5 = 7.5

The value of t is 7.5

What is the exact value of the expression the square root of 294. - the square root of 24. + the square root 54.? Simplify if po
dalvyx [7]
My solution to the problem is as follows:

sqrt(294) - sqrt(24) + sqrt(54) 
= sqrt(49 * 6) - sqrt(4 * 6) + sqrt(9 * 6) 
= sqrt(49)*sqrt(6) - sqrt(4)*sqrt(6) + sqrt(9)*sqrt(6) 
= 7*sqrt(6) - 2*sqrt(6) + 3*sqrt(6) 
= (7 - 2 + 3)*sqrt(6) 
= 8*sqrt(6) 
= sqrt(64)*sqrt(6) 
<span>= sqrt(384)

= 8*sqrt(6)

Therefore, the answer is letter B, 8 square root of 6

I hope my answer has come to your help. God bless and have a nice day ahead!

Please help me answer this question
strojnjashka [21]

Answer:

  • modulus: 3√2
  • argument: -3π/4  (or 5π/4)

Step-by-step explanation:

The modulus is the magnitude of the complex number; the argument is its angle (usually in radians).

__

<h3>rectangular form</h3>

The complex number can be cleared from the denominator by multiplying numerator and denominator by its conjugate:

  \dfrac{-9+3i}{1-2i}=\dfrac{(-9+3i)(1+2i)}{(1-2i)(1+2i)}=\dfrac{-9+3i-18i-6}{1+4}=-3-3i

<h3>polar form</h3>

The magnitude of this number is the root of the sum of the squares of the real and imaginary parts:

  modulus = √((-3)² +(-3)²) = 3√2

The argument is the arctangent of the ratio of the imaginary part to the real part, taking quadrant into consideration.

  arg = arctan(-3/-3) = -3π/4  or  5π/4 . . . . radians

__

  modulus∠argument = (3√2)∠(-3π/4)
