The required answer for the given expression is 0.
What is simplification?Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube roots, plus and minus.
Now the given expression is,
|8-40/4^3| 4^2 - 8
Solving the mod first,
Since 4^3 = 64 ; 4^2 = 16,
and 8 - 40 = -32
Therefore,
|8-40/4^3| 4^2 - 8 = |-32/64|16 - 8
Now solving
⇒ 32/64 = 1/2
Therefore we get,
|8-40/4^3| 4^2 - 8 = |-31/2| 16 - 8
Now since, |-a| = a
therefore, |-1/2| = 1/2
Therefore we get,
|8-40/4^3| 4^2 - 8 = (1/2) 16 - 8
Now, since (1/2) 16 = 8
Therefore we get
|8-40/4^3| 4^2 - 8 = 8 - 8
solving we get,
|8-40/4^3| 4^2 - 8 = 0
this is the required answer for the given expression.
Thus, the required answer for the given expression is 0.

what is the inverse of (x) = [tex]\sqrt{x+9}[/tex] x[tex]\geq[/tex] -9

f−1(x)=−(x−9)2, x≤9
f to the power of negative 1 end exponent left parenthesis x right parenthesis equals negative left parenthesis x minus 9 right parenthesis squared, , , x is less than or equal to 9
f−1(x)=x2−9, x≥0
f to the power of negative 1 end exponent left parenthesis x right parenthesis equals x squared minus 9, , , x is greater than or equal to 0
f−1(x)=x2−9, x≤0
The inverse of [tex]f[/tex], denoted [tex]f^{-1}[/tex], is such that

Given [tex]f(x)=\sqrt{x+9}[/tex], we have
[tex]f\left(f^{-1}(x)\right) = \sqrt{f^{-1}(x) + 9} = x[/tex]
Solve for [tex]x[/tex].
[tex]\sqrt{f^{-1}(x) + 9} = x[/tex]
[tex]\left(\sqrt{f^{-1}(x) + 9}\right)^2 = x^2[/tex]
[tex]f^{-1}(x) + 9 = x^2[/tex]
[tex]f^{-1}(x) = x^2 - 9[/tex]
Note that [tex]f(x)\ge0[/tex], so we must also have [tex]f\left(f^{-1}(x)\right) = x \ge 0[/tex]. This makes the third choice the correct one.
A cell phone company charges its customers $40 each month for owning a cell phone plan and $0.25 for
each minute the customer talks on the phone. These costs are modeled by the following equation:
C=25m +40, where Crepresents the total cost of the bill and m represents the number of minutes the
customer talked on the phone that month. Given this equation, how many minutes would the customer
have to talk on the phone for their monthly bill to be $84.25? (Hint: plug in 84.25 for the total cost, C, and
solve for the unknown, m).
Answer:
The customer would have 177 minutes to talk on the phone for their monthly bill to be 84.25
Step-by-step explanation:
Point of correction it's not C=25m +40 but it is
C=0.25m +40
Where,
C = $84.25➟ 84.25 = 0.25m + 40
Let's solve your equation step-by-step.
84.25=0.25m+40
Step 1: Flip the equation.
0.25m+40=84.25
Step 2: Subtract 40 from both sides.
0.25m+40−40=84.25−40
0.25m=44.25
Step 3: Divide both sides by 0.25.
0.25m/0.25 = 44.25/0.25
m=177
∴ The customer would have 177 minutes to talk on the phone for their monthly bill to be 84.25

Find the total amount given the original price and tax rate. Round to the nearest cent if necessary
$31.69, 6%
The total amount including the tax rate is found as $34.
What is defined as the percentage?A percentage is a fraction of a whole articulated as just a number between 0 and 100. Nothing is zero percent, everything is 100 percent, half of everything is fifty percent, and nothing is zero percent. To calculate a percentage, divide the fraction of the total by the total and multiply by 100.For the stated conditions in the question.
The original amount = $31.69.
The tax rate is 6%.
The total mount will be the sum of original amount and tax price.
First calculated the tax price;
6% of 31.69 = 6×31.69/100
6% of 31.69 = 1.9014
Tax price = $1.9014.
Total price = original amount + tax price
Total price = $31.69 + 1.9014
Total price = 33.5914
Total price = $34 (Round to the nearest cent.)
Thus, the total amount is estimated as $34.

The contrapositive statement is:
If x ≠ 2, then x^2 ≠ 4
And it is false.
How to write the contrapositive statement?
First, we have two propositions:
p = "x^2 = 4"
q = "x = 2"
The contrapositive statement is:
¬q → ¬p
The negation of the propositions are:
¬q = "x ≠ 2"
¬p = "x^2 ≠ 4"
Then the contrapositive statement with the given propositions is:
If x ≠ 2, then x^2 ≠ 4
Now, is this statement true?
No, because we can have:
x = -2 (which is different than 2, so the hypothesis is true)
and x^2 = (-2)^2 = 4
Then the conclusion is false, so the statement is false.

- The flag of Equatorial Guinea contains an isosceles triangle.
(Recall that an isosceles triangle contains two angles with the
same measure.) If the measure of the third angle of the trian-
gle is 30° more than twice the measure of either of the other
two angles, find the measure of each angle of the triangle.
(Hint: Recall that the sum of the measures of the angles of a
triangle is 180°.)
Please show me step by step how you got the answer, Thanks
The measure of each angle of the triangle is 40°, 40° and 100°.
What is the triangle?
A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.Given:
In an isosceles triangle two of the three angles measure the same.
Let the two angles be equal to x.
The third angle is 20 more than twice the measure of either angle, which means 2x+20.
The angles of a triangle add up to 180 degrees.
(x)+(x)+(2x+20)=180
4x+20=180
4x=160
x=40 degrees
So, the two angles measure 40° each and the third angle would be,
2x+20
=2*40+20
=100°
Therefore, the measure of each angle of the triangle is 40°, 40° and 100°.
