Hey there! :)
Answer:
C.
Step-by-step explanation:
For a graph to have a change in amplitude, there must be a coefficient in front of the equation, or the 'a' value.
Recall that the transformation form of a trigonometric graph is:
y = ±a(cos(b(x-h))+k
Where 'a' is the amplitude
'b' changes the period
'h' is a horizontal shift
'k' is a vertical shift
We can look at each choice and eliminate:
A. There is only a coefficient of -1 in front of the equation, which simply results in a reflection over the x-axis. This is incorrect.
B. This equation contains a b value of 2. This changes the period of the graph, not the amplitude. This is incorrect.
C. This equation contains a coefficient, or 'a' value of -2. The amplitude is changed by a factor of 2. This is correct.
D. This graph only contains a vertical shift of 1 unit up. This is incorrect.
Therefore, C is the correct answer.
Answer:
x=8
Step-by-step explanation:
We have been given with the function:
Here, we have same base of logarithmic function on both sides of the equation.
So, we will equate the values on right hand side and left hand side of the equation we will get
After simplification we will get
After further simplification we will get
Hence,
Therefore the correct answer is 8.
1500ML=1.5 Liters
Move decimal three places to the left, or divide 1500/1000
1000ML=1L
$.60 a lb.
Just divide $1.50 by 2.5lbs.
Total injuries on Turf are 1050 and 4.26% of the total injuries were severe. So find what is the 4.26% of 1050.
4.26% of 1050
Here of means multiplication as usually seen in mathematics.
So we can write:
4.26/100 x 1050
0.0426 x 1050
44.73
Round off and you will find the answer: 45 injuries on Turf were severe out of total injuries 1050.
