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
Answer:
15p
Step-by-step explanation:
<u>Let's interpret the question bit by bit</u>
<em>Salvador wrote 15 letters to friends each month</em>
=> 15 letters = 1 month
<em />
<em>For p months in a row</em>
let the total number of letters for p months be x
=> x letters = p months
<em>Bringing the two statements together gives;</em>
15 letters = 1 month
x letters = p months
<em>Now, let's solve for </em><em>x </em><em>by cross-multiplying the above</em>
x letters * 1 month = 15 letters * p months
x = 
x = 15p letters
Therefore, Salvador wrote a total of 15p letters for the p months.

Step-by-step explanation:
We conclude that the final amount that she has in her bank account is $375.
<h3>
How much has Tara in her bank account now?</h3>
Here we need to perform some additions and subtractions. We know that Tara starts with $350 in her account.
Then she received 3 checks for $35 each, so at this point she has:
$350 + 3*$35 = $455
Now she buys 2 video games for $41 each, so we need to subtract two times $41, we will get:
$455 - 2*$41 = $375
We conclude that the final amount that she has in her bank account is $375.
