Answer:

B

Step-by-step explanation:

so first you got to solve the expression  so -2.5(-1-2n)-1.5

−2.5(1−2n)−1.5n

Use the distributive property to multiply −2.5 by 1−2n.

−2.5+5n−1.5n

Combine 5n and −1.5n to get 3.5n.

your answer is  −2.5+3.5n  

if this is wrong then probably

solve the other expressions to see if u get the same answer

  • First of all, a 2 foot kangaroo is casting a 7 foot shadow.
  • Next we do 7 divided by 2 which equals 3.5.
  • Since we know the shadow is going to be 3.5x the object size we have to divide its shadow by 3.5
  • 14 divided by 3.5 is  4 so the Eucalyptus tree is 4ft long

<u><em>    Your answer=4ft </em></u>

<u><em></em></u>

Hope this helps!

Quick Please :) Exponents and powers
MrRissso [65]

Step-by-step explanation:

(  {4}^{ - 3} ) ^{ - 3}  =  {4}^{9}

( { - 4}^{9} )  ^{2} = ( - 4) {}^{18}

( {4}^{6} ) ^{ - 3}  =      \frac{1}{{4}^{18}}

(  { - 4}^{9} ) {}^{2}  = ( { - 4})^{18}

({4}^{0} ) =  {4}^{0}

Hope this is correct and helpful

HAVE A GOOD DAY!

Question 2 2.1 2.2 2.2.1 2.2.2 Determine the general solution for sin(x - 30°) = cos 2x Consider the functions f(x) = sin(x-30°)
OLEGan [10]

The general solution for the given equation is 40°+120°n.

The period of g(x) is π.

The range of f(x) is [-1, 1].

  • sin(x-30°) = cos 2x
  • sin(x-30°) = sin(90°-2x)
  • (x-30°) = (90°-2x) + 360°n
  • x + 2x =  90° + 30° + 360°n
  • 3x = 120° + 360°n
  • x = (120° + 360°n)/3
  • The general solution (x) is 40° + 120°n.
  • g(x) = cos 2x
  • The period of cos x is 2π.
  • If the multiplying factor of x is 'n', then it decreases the period by n times.
  • Here, in g(x), n is 2.
  • The period of g(x) is equal to half the period of cos x.
  • The period of g(x) = 2π/2
  • The period of g(x) is π.
  • f(x) = sin(x-30°)
  • "Sin" is a trigonometric function which has a range from -1 to 1.
