Answer:
B
Step-by-step explanation:
Given a sinusoidal function in the form f(x) = A Sin (Bx + C), we can say that:
A is the amplitude (if A is negative, the Amplitude is still the positive)
Period is
To get phase shift, we set Bx + C = 0 and solve for x.
Now, the function given is f(t) = -5 Sin (7t -1)
Hence, amplitude is 5
period is
and, phase shift is:
7t - 1 = 0
7t = 1
t = 1/7
Answer choice B is right.
Since x is less than 0 we have to use -2x.
Substitute -3 for x.
f(x) = -2(-3)
f(x) = 6
Answer:
x=24
Step-by-step explanation:
x/2+3=15
-3 both sides
x/2=15−3
15-3=12
x/2=12
12*2=24
x=24
Answer: If the length and width are both 2.5 times larger, the entire rectangle is 2.5 x 2.5 times larger.

Answer:
-7 is a Negative Number, which is also an integer.
Step-by-step explanation:
Negative numbers are any number less than 0. The greater a negative number is, is the smaller its value.
