The current temperature in Smallville is 20 degrees. This is 6 degrees less than twice the temperature that it was six hours ago
1 answer:
<u>ANSWER: </u>
The temperature in Small ville, six hours ago was 13 degrees.
<u> SOLUTION: </u>
Given, current temperature in Smallville is 20 degrees.
And this is 6 degrees less than twice the temperature that it was six hours ago.
We need to find what was the temperature six hours ago.
Let the temperature six hours ago be x.
Then, 2x - 6 = 20 [ according to the given information
2x = 20 + 6
2x = 26
x =
x = 13 degrees.
Temperature six hours ago was 13 degrees
Hence, the temperature in smallville , six hours ago was 13 degrees.

The equation of a parabola that has a vertex of (-2, 5.5) and passes through the point (-2.5, 2.5) is
The vertex form of the equation of a parabola is:
where (h, k) is the vertex of the parabola
(x, y) is the point that the parabola passes through
The vertex, (h, k) = (-2, 5.5)
The point, (x, y) = (-2.5, 2.5)
Substitute h = -2, k = 5.5, x = -2.5, and y = 2.5 into the equation to solve for a.
Therefore, the equation of the parabola is:

let's firstly, convert the mixed fraction to improper fraction, and then subtract.
Answer:
1). = (200 -
)
2). Inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
Step-by-step explanation:
Function representing the maximum heart rate is,
f(x) = 0.85(220 - x)
Here x = age of the client
Equation form of the function will be,
y = 0.85(220 - x)
To get the inverse of the given function, replace 'x' by 'y' and 'y' by 'x' and solve for y.
x = 0.85(220 - y)
220 - y =
y = 220 -
Now convert this equation into a function.
= (200 -
)
Here inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
