Answer:
The answer to your question is:
Domain [0, 8)
Range [-3, 1]
f(0) = -3
Step-by-step explanation:
Domain: is the possible values that the "x" can take
Range: are the values that take the function when is evaluated by the independent variable (x).
For this example:
Domain [0, 8) close is zero and open in 8
Range [-3, 1] close in both sides
f(0) = -3
Set up a proportion. 3.50 over 5 = x over 1 (x is what we are trying to find= the cost of 1 lb of apples)
Use cross products and multiply 3.50 by 1 to get 3.50 and then divide that by 5 to get 0.7.
So the apple cost 0.7 or seventy cents per pound.
Check: 0.7*5=3.5
That is correct!
Hope this helps!

Answer:
D -24/25
Step-by-step explanation:
sin(2x) = 2sin(x)cos(x)
cos(x) = ⅘
sin²(x) = 1 - cos²(x) = 1 - (⅘)²
sin²(x) = 9/25
sin(x) = -⅗
(Because 4th quadrant)
sin(2x) = 2(-⅗)(⅘)
= -24/25
Answer:
false
Step-by-step explanation:
32 = 6(1) - 4
According to PEMDAS (parentheses/exponents | multiplication/division | additions/subtraction), we should multiply first.
32 = 6 - 4
Now let's subtract.
32 = 2
This statement is incorrect; therefore it is not true.
