Answer:
one: 9
Two: D
Step-by-step explanation:
One
The symbol used is x≥8 so 8 is included in the function part. That would mean that F(x) = 9
Two
The value you need to use is -4x + 3. That's because -2≤x and the symbol ≤ makes - 2 inclusive.
-4(-2) + 3 = 8 + 3 = 11
3a
The function is decreasing over -4x + 3
It goes from 11 to -29 roughly. That means it's going from a positive to negative number. Definitely decreasing
3b
The function is a constant when x≥8. The value of the function is 9 no matter what x is.
3c
The function is increasing from - 2x to 8 which is going from -9 to 11
Answer:
A. 6.8 ft.
Step-by-step explanation:
Attached solution and work.
For 27 since all they did was add a zero on the end of the first number (9,554), you just add that zero to the end of you quotient to make 95,540 / 562 = 170
For 28 the answer is 110.59 (rounded to nearest hundredth) because you take the distance between the moon and earth and divide it by the width of the moon 384,400 / 3,476 = 110.58688
Hope this helps!
