Bogdan [553]3 years ago
7 0

Answer:

Hope that this is helpful.

Step-by-step explanation:

-3(2x-1)^2+12x^2

= -3[(2x-1)(2x-1)]+12x^2

=-3[2x(2x-1)-1(2x-1)]+12x^2

=-3(4x^2-2x-2x+1)+12x^2

=-3(4x^2-4x+1)+12x^2

=-12x^2+12x-3+12x^2

=(-12x^2+12x^2) +12x-3

=0+12x-3

=12x-3

Two angles are complementary. The larger angle is 6 more than twice the smaller angle. Write an equation to find the measure of
Tatiana [17]

Let x = the smaller angle

then 2x + 6 = the larger angle

Since they are comlementary, then their sum is 90°

smaller angle + larger angle = 90°

(x) + (2x+6) = 90

3x + 6 = 90

3x = 84

x = 28 (this is the smaller angle)

the larger angle is 2x + 6 = 2(28) + 6 = 56 + 6 = 62


Answer: smaller angle is 28, larger angle is 62

Can some one please help me ?
Phoenix [80]

9514 1404 393

Answer:

  a) 1/2

  b) 1/2

Step-by-step explanation:

a) The average rate of change is the slope of the segment whose end points are the ends of the interval. On the interval [2, 8] the average rate of change is ...

  m = (f(8) -f(2))/(8 -2) = (4 -1)/6 = 3/6 = 1/2

The average rate of change on the interval [2, 8] is 1/2.

__

b) In this context, "slope" and "average rate of change" mean the same thing. A line with the same slope will have a slope of 1/2.

Dustin needed 0.80 meter of fabric to make a pillow. The fabric cost $1.50 per meter. How much did Dustin pay for 0.80 meter of
aliina [53]

Given parameters:

Length of fabric needed to make a pillow = 0.8m

Cost of fabric per meter = $1.5

Unknown:

Cost of the 0.8m fabric  = ?

Solution:

  The cost of the fabric  = cost per meter x length of fabric

   Input the parameters and solve;

       Cost of the fabric  = 0. 8 x 1.5 = $1.2

Dustin will have to $1.2 for the fabric
