Answer:
y = 0.5 cosine (4 (x - pi/2)) - 2
Step-by-step explanation:
Taking the general form:
y = A cosine (Bx - Cπ)) + D
In the following case. the constants are:
y = 0.5 cosine (4x - 2π)) - 2
A: 0.5
B: 4
C: 2π
D: -2
The range of this function is:
range = [-|A|+D, |A|+D]
range = [-0.5-2, 0.5-2]
range = [-2.5, -1.5]
Which coincides with "It has a maximum at negative 1.5 and a minimum at negative 2.5"
At x = 0, the function value is:
y = 0.5 cosine (4(0) - 2π)) - 2
y = 0.5 - 2 = -1.5
As indicated in "a curve crosses the y-axis at y = negative 1.5"
The period of the function is:
period: 2π/B
period = 2π/4 = π/2 or 2 cycles at π
as described in "It goes through 2 cycles at pi."

1) Since these triangles are congruent, then we can write out the following for congruent triangles have congruent sides:
2) Still based on that principle, we can plug v=2 into any of those formulas to get the measure of QS and TV. So let's pick the simpler one:
As we can see these segments are congruent.
Answer: The correct option is B-He left out the place holder under the 4.
Step-by-step explanation:
Consider the provided multiplication.
Jared need to multiply 36.47 with 12
The correct multiplication should be:
36.47
× 12
7294
36470
43764
Now consider the Jared's work he just left out the place holder under the 4.
Because it is not just 1×36.47 it is actually 10×36.47, so he needs to add a zero under the number 4.
1. 37.6
2. 19.4
