Ответ:
means that at time t min, the height h of the balloon is 210-15t (units)
for example,
at time t=1 min, the height of the balloon is 210-15*1=195 (units)
at time t=2 min, the height of the balloon is 210-15*2=210-30=180 (units)
Thus, h(10) is the height of the balloon at time t=10 min,
h(10)=210-15*10=210-150=60
Ответ:
t represents time, which is the input of the function, so we know that 10 is the time in minutes. h(t) represents the altitude, which is the output of the function after time, t. So, we need to substitute 10 into 210 – 15t in place of t. Simplifying 210 – 15(10), we get that 60 is the altitude in feet. So, after 10 minutes, the hot air balloon is at 60 feet.

Fraction = 4/7
Step by step Explanation
Let the denominator be x.
Numerator = 3 less than denominator
denominator = x
Numerator = (x – 3)
Now, Adding 5 to denominator
adding 2 to numerator.
Numerator = (x – 3 + 2)
Denominator = (x + 5)
(x – 3 + 2)/(x + 5)
According to the question
(x – 3 + 2)/(x + 5) = 1/2
(x – 1)/(x + 5) = 1/2
2(x – 1) = 1(x + 5)
2x – 2 = x + 5
2x – x = 5 + 2
x = 7
So,
=> Denominator x = 7
=> Numerator (x – 3) => (7 – 3) = 4
= > Fraction = 4/7
