Answer: T(90) = 93.413 F
Step-by-step explanation:
The temperature T of an object in degrees Fahrenheit after t minutes is represented by the equation
T(t) = 69e−0.0174t + 79.
T is the dependent variable while t is the independent variable. To determine any value for Temperature, we will input the corresponding value for time into the function.
We want to determine the temperature of the object after one and a half hours. This means that we have to convert one and a half hours to minutes
1f 1 hour = 60 minutes
Then 1.5 hours = 1.5 × 60 = 90 minutes.
We would substitute t = 90 minutes into the equation, it becomes
T(90) = 69e−0.0174×90 + 79
T(90) = 69e−1.566 + 79
T(90) = 14.413 + 79
T(90) = 93.413 F
H(x) = 16 - x
plug -4 in as x
H(x) = 16 - (-4)
solve 16 - (-4)
H(x) = 20
your answer is A)20
Answer:
$12.86
Step-by-step explanation:
multiply 13.50 by 0.05 and subtract the answer from 13.50
Answer: two over three
Step-by-step explanation:
line intercepts y at (0,-2)
Therefore, 
Substitute x = 3 in y =ax-2
To find the x-intercept, y = 0
The slope is 2/3
y-intercept is -2
So two over three
Answer:
96
Step-by-step explanation:
If B is the midpoint of AC, the length of AC has to be twice the length of AB. This is because AB = AC. Twice 48 is 96.
