Answer:

(12 + 15) \div 3 + 2 \times4

Step-by-step explanation:

<u>*Follow the PEMDAS order of operations*</u>

<u />\left(12+15\right)\div \:3+2\times \:4

<u>calculate within parentheses;-</u>

<u />\left(12+15\right)

=27\div \:3+2\times \:4

<u>Divide:-</u>

<u />27\div3=9

=9+2\times \:4

<u>Multiply:-</u>

<u />2\times \:4=8

=9+8

=17

What is the total weight for each group of weight of clay lumps
Verizon [17]
Hey, me again! So, I'll be giving you the totals for EACH group.

For the first group, multiply 1/8 by 3 to get the answer;
3/8 lbs

Do the same for this group (and all of the others) so that the answers are:
Group 2 - 3/4lbs
Group 3 - 2/2 = 1lb
Group 4 - 5/8lb
Group 5 - 7/8

A sine function has the following key features: Period = 4 Amplitude = 3 Midline: y=−1 y-intercept: (0,-1) The function is not a
mezya [45]

Answer:

  • See the graphs attached and the explanation below

Explanation:

The most simple sine function, considered the parent function, is:

     y=sin(x)

That function has:

  • Midline, also known as rest or equilibrium position: y = 0
  • Minimum: - 1
  • Maximum: 1
  • Amplitude: the distance between a minimum or a maximum and the midline = 1
  • period: the interval of repetition of the function = 2π

The more general sine function is:

             y=Asin(Bx+C)+D

That function has:

  • Midline: y = D (it is a vertical shift from the parent function)
  • Minimum: - A + D
  • Maximum: A + D
  • Amplitude: A
  • period: 2π/B
  • phase shift: C (it is a horizontal shift of the from the parent function)

Now, you have to draw the sine function with the given key features:

  • Period = 4 ⇒ 2π/B = 4 ⇒ B = π/2
  • Amplitude, A = 3
  • midline y = - 1 ⇒ D = - 1
  • y-intercept = (0, -1)

Substitute the know values and use the y-intercept to find C:

       

            y=3sin(2x/\pi+C)-1

Substitute (0, -1)

             

              -1=3sin(0+C)-1\\ \\ 3sin(C)=0\\ \\ sin(C)=0\\ \\ C=0

Hence, the function to graph is:

              y=3sin(\pi x/2)-1

To draw that function use this:

  • Maxima: 3(1) - 1 = 3 - 1 = 2, at x = 1 ± 4n (n = 0, 1, 2, 3, ...)
  • Minima: 3(-1) - 1 = - 3 - 1 = -4
  • y-intercept: (0, - 1)
  • x-intercepts: the solutions to 0 = 3sin(πx/2) = - 1
  • first point of the midline: (0, -1) it is the same y-intercept

With that you can understand the graphs attached.
