Weight goes 4 feet down before hitting the pool
therefor the pool is 12-4 ft or 8ft deep
(12)+(-4)=8 is the sum of integers
12 is an integer
-4 is an integer
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.
When 0 < a < 1, the amplitude of the graph decreases, causing the slopes of the graph to appear more "flat".
Answer:
The third table of values matches the equation and includes only viable solutions.
Step-by-step explanation:
Loaves of bread: b can't be a negative value, then the first table doesn't include viable solutions.
The number of loaves of bread must be a whole number, then the second table doesn't include viable solutions.
c=3.5b
if b=0→c=3.5(0)→c=0
If b=3→c=3.5(3)→c=10.5
If b=6→c=3.5(6)→c=21
If b=9→c=3.5(9)→c=31.5
The third table includes viable solutions
Answer:
x = 5, y = 4
Step-by-step explanation:
x + 4y = 21
4x - 16 = y
x + 4(4x - 16) = 21
x + (16x - 64) = 21
(17x - 64) = 21
17x = 85
x = 85/17
x = 5
___________________
x + 4y = 21
5 + 4y = 21
4y + 5 = 21
4y = 16
y = 16/4
y = 4
