The solution to the piecewise problem given are :

  1. Difference in cost of 2 and 3 line ad is 0
  2. Cost of 10-line ad = $108
  3. Cost of 11 - line ad = $117

From the piecewice function given :

x = number of lines in ad

The cost of ad when x ≤ 3 is 45

Hence, the cost of a 2 and 3 line ad is 45, Therefore, the difference is 0 ;

The cost of a 10 - line ad ;

x = 10

Cost = 45 + 9(x - 3)

Cost = 45 + 9(10 - 3)

Cost = 45 + 9(7)

Cost = 45 + 63 = 108

The cost of a 11 - line ad ;

x = 11

Cost = 45 + 9(x - 3)

Cost = 45 + 9(11 - 3)

Cost = 45 + 9(8)

Cost = 45 + 72 = 117

Hence, the solution to the piecewise related questions.

Question 21

Let's complete the square

y = 3x^2 + 6x + 5

y-5 = 3x^2 + 6x

y - 5 = 3(x^2 + 2x)

y - 5 = 3(x^2 + 2x + 1 - 1)

y - 5 = 3(x^2+2x+1) - 3

y - 5 = 3(x+1)^2 - 3

y = 3(x+1)^2 - 3 + 5

y = 3(x+1)^2 + 2

Answer: Choice D

============================================

Question 22

Through trial and error you should find that choice D is the answer

Basically you plug in each of the given answer choices and see which results in a true statement.

For instance, with choice A we have

y < -4(x+1)^2 - 3

-7 < -4(0+1)^2 - 3

-7 < -7

which is false, so we eliminate choice A

Choice D is the answer because

y < -4(x+1)^2 - 3

-9 < -4(-2+1)^2 - 3

-9 < -7

which is true since -9 is to the left of -7 on the number line.

============================================

Question 25

Answer: Choice B

Explanation:

The quantity (x-4)^2 is always positive regardless of what you pick for x. This is because we are squaring the (x-4). Squaring a negative leads to a positive. Eg: (-4)^2 = 16

Adding on a positive to (x-4)^2 makes the result even more positive. Therefore (x-4)^2 + 1 > 0 is true for any real number x.

Visually this means all solutions of y > (x-4)^2 + 1 reside in quadrants 1 and 2, which are above the x axis.

What is the value of the y-intercept of the graph of h(x) = 1.2(4.15)^x?
gizmo_the_mogwai [7]

9514 1404 393

Answer:

  h(0) = 1.2

Step-by-step explanation:

The y-intercept is h(0). When x=0, the exponential term evaluates to 1, so the y-intercept is the multiplier of the exponential term.

  h(0) = 1.2 . . . the y-intercept

Angle BAC measures 56. What is the measure of angle BDC?
goldfiish [28.3K]

Answer: Like the angles BAC (56°) and BDC has the same arc BC in the circumference, these angles must be congruent, then angle BDC must be equal to 56°.
