Given the function f(x) = 0.5|x - 41-3, for what values of x is f(x) = 7?
x = -24, x = 16
x= -16, x = 24
x=-1, x = 9
x = 1, x = -9
Answers
The values of x for which f(x) = 7 are x = 61 and x = 21.
To find the values of x for which f(x) = 7, we can set up the equation and solve for x.
The given function is f(x) = 0.5|x - 41| - 3.
Setting f(x) equal to 7, we have:
0.5|x - 41| - 3 = 7.
First, let's isolate the absolute value term:
0.5|x - 41| = 7 + 3.
0.5|x - 41| = 10.
To remove the absolute value, we can consider two cases:
Case: (x - 41) is positive or zero:
0.5(x - 41) = 10.
Multiplying both sides by 2 to get rid of the fraction:
x - 41 = 20.
Adding 41 to both sides:
x = 61.
So x = 61 is a solution for this case.
Case: (x - 41) is negative:
0.5(-x + 41) = 10.
Multiplying both sides by 2:
-x + 41 = 20.
Subtracting 41 from both sides:
-x = -21.
Multiplying both sides by -1 to solve for x:
x = 21.
So x = 21 is a solution for this case.
Therefore, the values of x for which f(x) = 7 are x = 61 and x = 21.

The loudness, L, measured in decibels (Db), of a sound intensity, I, measured in watts per square meter, is defined as , where and is the least intense sound a human ear can hear. What is the approximate loudness of the intense music concert, measuring an intensity of 10-1, Adrian and Trey are attending?
Answers
The approximate loudness of the intense music concert, measuring an intensity of 10-1 watts per square meter, is 20 decibels.
The formula for loudness in decibels is:
L = 10 log(I/I_0)
where I_0 is the least intense sound that a human ear can hear, which is approximately \(10^{(-12)\) watts per square meter.
Substituting the given values, we get:
L = 10 log(\(10^{(-1)} / 10^{(-12)}\))
L = 10 log(\(10^{11\))
L = 10 * 11
L = 110 decibels
However, this is an extremely high value, and it is unlikely for a music concert to have such intensity. Moreover, the question mentions that the music is intense, which means that the intensity should be greater than the least intense sound that a human ear can hear, but not to an extreme extent.
Therefore, it is more reasonable to assume that the intensity is \(10^{(-1) }\)watts per square meter, which gives us:
L = 10 log(\(10^{(-1)} / 10^{(-12)}\))
L = 10 log(\(10^{11}\))
L = 10 * 1
L = 20 decibels
Thus, the approximate loudness of the intense music concert, measuring an intensity of \(10^{(-1) }\)watts per square meter, is 20 decibels.

4. Prove by mathematical induction that n² +n < 2" whenever n is an integer greater than 4.
Answers
Step-by-step explanation:
n² + n < 2^n
so, let's see what happens, when I increase n by 1
(n+1)² + n + 1 < 2^(n+1) = 2×2^n
n² + 2n + 1 + n + 1 < 2×2^n
n² + 3n + 2 < 2×2^n = 2^n + 2^n
so, we added on the left and on the right side of the inequality sign compared to the original relation :
2n + 2 vs. 2^n
so, once the original relation becomes true (and we see by trying that for n = 1, 2, 3 and 4 it is not, but for n = 5 it becomes true), the next integer follows the original inequality plus the expressions mentioned above.
n² + n + (2n + 2) < 2^n + (2^n)
this inequality will remain true, if
2n + 2 <= 2^n
n + 1 <= 2^(n-1), which is true for n > 2 (and therefore also n > 4), because the "power of" function 2^n progresses much faster than a simple n+1
and therefore this relation remains true for any larger n.

c: When x = 5, y = 11.
How to explain the informationa If the points in a dataset appear to fall in a straight line when plotted, it suggests a possible linear relationship between the variables being considered. A linear relationship means that there is a constant rate of change between the variables, and a linear regression model could potentially be used to model and predict the relationship between them.
b The equation of best fit is y = 2x + 1. This can be found using the least squares method, which is a statistical technique for finding the line that best fits a set of data points.
Part c: When x = 5, y = 11. This can be found by substituting x = 5 into the equation y = 2x + 1. It is clear that the points fall very close to the line, which indicates that the line is a good fit for the data.

Miss Lianto mowed 2 7 of her lawn. Her son mowed 1 3 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
HURRY!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
8/21 of the lawn still needs to be mowed.
To compare fractions, we need a common denominator. The least common multiple of 7 and 3 is 21.
Miss Lianto's fraction: (2/7) x (3/3) = 6/21
Son's fraction: (1/3) x (7/7) = 7/21
To calculate how much of the lawn still needs to be mowed, we can subtract the combined fractions mowed from the total:
Combined fractions mowed: 6/21 + 7/21 = 13/21
So, Remaining fraction: 1 - 13/21 = 8/21
Therefore, 8/21 of the lawn still needs to be mowed.

If you vertically compress the square root parent function f(x) = ^x, by 1/2 of a unit what is the equation of the new function
Answers
Answer:
The equation of the new function is \(g(x) = \frac{\sqrt{x}}{2}\)
Step-by-step explanation:
Suppose we have a function f(x).
a*f(x), a > 1, is vertically stretching f(x) a units. Otherwise, if a < 1, we are vertically compressing f(x) by a units.
f(x - a) is shifting f(x) a units to the right.
f(x + a) is shifting f(x) a units to the left
In this question:
\(f(x) = \sqrt{x}\)
Vertically compressing by 1/2:
This is the same as multiplying the function by 1/2. So
\(\frac{1}{2} \times \sqrt{x} = \frac{\sqrt{x}}{2}\)
The equation of the new function is \(g(x) = \frac{\sqrt{x}}{2}\)

Answers
you'll want to work with the center-radius form of a circle equation for this. the center formula is \((x - h)^2 + (y - k)^2 = r^2\), where \((h, k)\) is your center and r is your radius. plug in the information your circle gives you: \(A(-3, 12)\), \(\text{radius} = 5\)
\((x + 3)^2 + (y - 12)^2 = (5)^2\) ... simplify the right side
\((x + 3)^2 + (y - 12)^2 = 25\) ... from here, you need to foil both of your binomials to convert this to the "general form" that your answer choices are in.
\((x + 3)^2 = (x + 3)(x + 3) = x^2 + 6x + 9\)
\((y - 12)^2 = (y - 12)(y - 12) = y^2 - 24y + 144\)
\(x^2 + 6x + 9 + y^2 - 24y + 144 = 25\) ... combine like terms
\(x^2 + 6x + y^2 - 24y + 153 = 25\) ... subtract 25
\(x^2 + 6x + y^2- 24y + 128 = 0\) is your equation. reorder it so that it's from the highest degree to the lowest:
\(\boxed{\bold{x^2 + y^2 + 6x - 24y + 128 = 0}}\)
