44 you should subtract 80 and 36 then the answer will be 44
Let's write the general form of the sine curve:
, 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 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 , NOT . So this is not correct.
ANSWER: C is true
First, let's look at the ratio.
You also know that for every 8 indoor events, there is 3 field events.
Therefore, the amount of indoor events is 8 on 11 events total, as 8 + 3 = 11
Then, let's look at the actual number of events. If there is 22 events total, you need to solve this proportion :
Answer:
The 40th number in the pattern is 9.
because it repeats every 4 numbers, so you just can change this pattern into normal, like 1 2 3 4 ... and just count, or you can just divide every number given in the choices by four
Answer: 6 batches
Step-by-step explanation:
From the question, we are informed that one batch of cookies requires 2⁄3 cup of flour.
Therefore, the number of batches that can be made with 4 cups of flour will be:
= 4 / 2/3
= 4 × 3/2
= 12/2
= 6 batches
