suzy uses 1/2 cup of raisins for every 1 1/4 cup of sugar cookies. How many sugar cookies does Suzy need for 2 cups of raisins?
Mandarinka [93]
5 cups.

To go from 1/2 to 2 cups of raisins you multiply by 4.
So 1 1/4 is really 5/4. That times 4 is 20/4 which is 5.

Assume a and b are whole numbers, and a>b. Which expression has the least value?
dedylja [7]

a > b

A . a^5b^3/ab^4 = a^4/b

B. a^4 / a*a*a*a = a^4 / a^4 = 1

C. ab^2 / a^2b = b/a

D. b*b*b/b^3 = b^3/b^3 = 1

B and D, doesn't matter what values of a and b it's always equal 1

Lets say a = 2 and b = 1

A. a^4/b = 2^4 / 1 = 16/1 = 16

C. b/a = 1/2 = 0.5

So C has the least value

Answer:

ab^2 / a^2b

Which of the following is true for f(x)= -2sin(x)-3?
serious [3.7K]

Let's write the general form of the sine curve:

f(x)=AsinB(x+C)+D, where,

  • A is the amplitude. Also, if A is negative, curve reflects about x axis
  • B is the compression/stretching factor. It changes the period when it is a value other than 1.
  • C is the phase shift. It translates curve left or right. Negative value shifts right and positive value shifts left.
  • D is the vertical shift. It translates curve up or down. Negative value shifts down and positive value shifts up.

Let's check the 4 choices.

A.

Since this curve's A is -2, its amplitude is 2 and range is from -2 to 2. BUT since D value is -3, it shifts vertically 3 units down making the range from -1 to -5. Clearly choice A is not true.

B.

This graph is the graph of f(x)=-2sin(x) shifted 3 units DOWN since D is negative. This choice isn't true.

C.

Because of the - (minus) sign in front of the function, the function is reflected about x-axis, but amplitude doesn't change. Since A value is 2, amplitude is 2. This is true.

D.

Period depends on the B value. Here, B value is 1, so period is normal as the parent function of a sine curve, which is 2\pi, NOT 4\pi. So this is not correct.


ANSWER: C is true
