Answer:
the answer is 40√3feet per second
Step-by-step explanation:
v=√16.√300
v= 4. 10√3
NB:10√3=√100 .√3=√100.3= √300
Hence v =40√3ft per second
I think x is equaled to 29/39
number - n
Twice a number - 2n
Seven times the number - 7n
2n = 7n +35
7n-2n = -35
5n = -35
n = - 7
Check:
2(-7) = 7(-7) +35
-14 = -49 + 35
-14 = -14 True
The number is (- 7).
Answer:
Setting
Step-by-step explanation:
We can calculate for the slope of the line using the
formula:
m = (y2 – y1) / (x2 – x1)
From the given values:
m = (4,000 – 10,000) ft / (15 – 0) min
m = -400 ft/min
This means that the altitude is decreasing by 400 ft per
minute.
> The slope is –400 . This means that the helicopter
descends 400 ft each minute.
