The inverse of a function [tex]f(x) = \sqrt{3x + 6}[/tex] is [tex]f^{-1} (x) = \frac{x^{2}-6 }{3}[/tex].
Here,
A function is given as, [tex]f(x) = \sqrt{3x + 6}[/tex]
We have to find the inverse of given function.
What is Inverse function?
An inverse function is a function that undoes the action of the another function.
Now,
A function is given as, [tex]f(x) = \sqrt{3x + 6}[/tex]
To find inverse function,
Replace f(x) by y in the equation,
[tex]y = \sqrt{3x + 6}[/tex]
[tex]y^{2} = 3x + 6\\y^{2} -6 = 3x \\x = \frac{y^{2} - 6\\}{3}[/tex]
Replace every x by a y and solve for y, we get;
[tex]y = \frac{x^{2} - 6\\}{3}[/tex]
Replace y by [tex]f^{-1} (x)[/tex], we get,
[tex]f^{-1} (x) = \frac{x^{2}-6 }{3}[/tex]
Hence, The inverse of a function [tex]f(x) = \sqrt{3x + 6}[/tex] is [tex]f^{-1} (x) = \frac{x^{2}-6 }{3}[/tex].

Allison works in a department store selling
clothing. She makes a guaranteed salary of $350
per week, but is paid a commission on top of her
base salary equal to 15% of her total sales for the
week. How much would Allison make in a week in
which she made $300 in sales? How much would
Allison make in a week if she made xx dollars in
sales?
Answer:
a. $395
b. $(350 + 0.15x)
Step-by-step explanation:
Her income in a week can be written as;
$350 + 15% of sales
a. In the case of $300 sales in a week
Mathematically, that would be;
$350 + 15% of $300
$350 + (15/100 * 300)
$350 + $45 = $395
b. In the case of $x in sales
= $350 + 15% of x
= $350 + (15/100 * x)
= $350 + 0.15x
= $(350 + 0.15x)
Divide up to two decimal places.

35.60744985673352
= 35.61(2d.p)
Explanation:
When you divide it you get 35.60744985673352
To leave it in to 2 decimal place, you are to consider the the third number after the point which in this case is 7. So you check if it is greater than or equal to or less than 5. If it is greater than or equal to 5 you carry forward 1 to the next digit to the left which is 0 in this case which will give you 1, then you retrieve the number plus the first two decimals after the point to get 35.61(2d.p).

Sam knows that his annual homeowners insurance premium is $0.27 per $100 of value, which usually works out to be $683.10 annually. But Sam is confused by a letter from his insurance company telling him that an increase in the value of his home has led to an increase in his annual homeowners insurance premium. He is now being charged an annual premium of $720.90. Based on the increase in his annual homeowners insurance premium, what was the increase in his home's value? (Note: The cost is still $0.27 per $100, even though the annual premium went up.)
Answer:
C. $14,000
Step-by-step explanation:
If he is now being charged an annual premium of $720.90. The increase in his home's value is $14,000.
Increase in home valueIncrease in home value=[(720.90/0.27)-(683.10/0.27)]×$100
Increase in home value=(2670-2530)×$100
Increase in home value=140×$100
Increase in home value=$14,000
Therefore the increase in his home's value is $14,000.

Step-by-step explanation:
[tex]10t - 5 = 60[/tex]
Using the addition property add 5 to both sides of the equation
That's
[tex]10t - 5 + 5 = 60 + 5 \\ 10t = 65[/tex]
Divide both sides by 10
[tex] \frac{10t}{10} = \frac{65}{10} \\ t = \frac{65}{10} [/tex]
Reduce the fraction with 5

The set of three numbers could be the side lengths of a right triangle is to be considered as the option d. 14,48,50.
What is Pythagoras theorem?It is a theorem that should be attributed to Pythagoras where the square of the hypotenuse of a right triangle is equivalent to the sum of the squares of the other two sides.
So based on this we can say that

2a-2c=4a solve for a
Answer:
a = - c
Step-by-step explanation:
2a - 2c = 4a
- 4a - 4a
- 2a - 2c = 0
+ 2c + 2c
- 2a = 2c
/-2 /-2
a = - c
Answer:
[tex]\boxed {a = -c}[/tex]
Step-by-step explanation:
Solve for the value of [tex]a[/tex]:
[tex]2a - 2c = 4a[/tex]
-Take [tex]4a[/tex] and subtract it from [tex]2a[/tex]:
[tex]2a - 2c - 4a = 4a - 4a[/tex]
[tex]-2a - 2c = 0[/tex]
-Add both sides by [tex]2c[/tex]:
[tex]-2a - 2c + 2c = + 2c[/tex]
[tex]-2a = 2c[/tex]
-Divide both sides by [tex]-2[/tex] and dividing [tex]-2[/tex] undoes the multiplication by [tex]-2[/tex]:
[tex]\frac{-2a}{-2} = \frac{-2c}{-2}[/tex]
[tex]\boxed {a = -c}[/tex]
Therefore, the value of [tex]a[/tex] is [tex]-c[/tex].
The denominator of a fraction is one more than the numerator. If 3 is subtracted to
the numerator and to the denominator, the resulting fraction is equivalent to 1 . What is the 2
original fraction?
Answer:
[tex]\frac{4}{5}[/tex]
Step-by-step explanation:
let the original fraction be
[tex]\frac{n}{n+1}[/tex] ( with denominator 1 more than numerator )
Subtracting 3 from numerator/ denominator gives
[tex]\frac{n-3}{n+1-3}[/tex] = [tex]\frac{n-3}{n-2}[/tex]
Given that the fraction is now equivalent to [tex]\frac{1}{2}[/tex] , then
[tex]\frac{n-3}{n-2}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2(n - 3) = n - 2, distribute left side
2n - 6 = n - 2 ( subtract n from both sides )
n - 6 = - 2 ( add 6 to both sides )
n = 4
and n + 1 = 4 + 1 = 5
Thus original fraction is [tex]\frac{4}{5}[/tex]

Morse code uses "dots" and "dashes," which are known to occur in the proportion of 3:4. This means that for any given symbol, P(dot sent) = 3/7 and P(dash sent) = 4/7. Unfortunately, when coded messages are sent, there are sometimes errors in transmission. Suppose there is interference on the transmission line, and with probability 1/8 a dot is mistakenly received as a dash, and vice versa. a) What is the probability that the received symbol is a dot?
Answer: [tex]\dfrac{25}{56}[/tex]
Step-by-step explanation:
Given: P(dot sent) = [tex]\dfrac37[/tex]
and P(dash sent) = [tex]\dfrac47[/tex]
P(dot received) = P(dot received ∩ dot sent)
+ P(dot received ∩ dash sent)
= P(dot received | dot sent)P(dot sent) + P(dash received | dash sent)P(dash sent) [By conditional probability formula]
[tex]=\dfrac78\times\dfrac37+\dfrac18\times\dfrac47=\dfrac{25}{56}[/tex]
Hence, the probability that the received symbol is a dot = [tex]\dfrac{25}{56}[/tex]
