So I paid someone $25.95 ok but I didn’t realize I owed them $28.21 till now…how much do I owe them?!!???
Answers
Answer:
$2.26
Step-by-step explanation:
In total, you owed them 28.21, and so you can subtract the amount you paid from the total:
28.21 - 25.95 = 2.26
So, you owe them $2.26 now.

The value of f(x) when x = 3 is 4
How to evaluate the piecewise function?The definition of the piecewise function is given as:
[tex]f(x) = \left[\begin{array}{cc}-x& x \le -1\\1&x = 0\\x + 1&x \ge 1\end{array}\right[/tex]
When x = 3, the domain is [tex]x \ge 1[/tex]
At [tex]x \ge 1[/tex], the function definition is
f(x) = x + 1
So, we have:
f(3) = 3 + 1
Evaluate
f(3) = 4
Hence, the value of f(x) when x = 3 is 4

What is the value of f(x) when x=3?
Answer:
4
Step-by-step explanation:
A moving company’s moving rates can be represented by the function f(x) = 3x + 400, where x is the number of miles for the move.
Another moving company’s rates can be represented by the function g(x) = 5x + 200.
Which function represents the difference between the moving companies' rates, h(x) = f(x) – g(x)?
Answers
The difference betweeh the two companies' moving rates is:
(f - g)(x) = -2x + 200
Which function represents the difference between the moving companies' rates?Here we have two functions:
f(x) = 3x + 400
g(x) = 5x + 200
These functions represent the moving rates for two different companies.
If we want to find the difference between the moving rates, we just need to take the difference between the functions:
(f - g)(x) = f(x) - g(x) = (3x + 400) - (5x + 200) = -2x + 200
So the difference betweeh the two companies' moving rates is:
(f - g)(x) = -2x + 200

Naomi was asked to show that point DDD is equidistant from points AAA and CCC.
Answers
A line bisector is a straight line that divides a given line into two equal parts. Thus the following steps are required by Naomi to show that point D is equidistant from points A and C.
BD ⊥ AC (given)
BD = 3 units, and AC = 8 units.
BD is the perpendicular bisector of segment AC (given)
Thus,
<BDA ≅ <BDC (right angles formed by a perpendicular bisector)
AD ≅ DC (equal parts of a bisected line)
AD ≅ DC = 4 units
Thus joining points B to A, and B to C,
BA ≅ BC.
So that applying Pythagoras theorem to ΔABD, we have:
[tex]/hyp/^{2}[/tex] = [tex]Adj 1^{2}[/tex] + [tex]Adj 2^{2}[/tex]
[tex]AB^{2}[/tex] = [tex]3^{2}[/tex] + [tex]4^{2}[/tex]
= [tex]\sqrt{25}[/tex]
AB = 5 units
So that,
BA ≅ BC = 5 units
Therefore, it can be concluded that point D is equidistant from points A and C.

9x² - 4[tex]y^{6}[/tex] = (3x)² - (2y³)²
with U = 2x and V = 2y³
Answer:

9x^2= (3x)^2
4y^6 = (2y^3)^2
=(3x)^2 - (2y^3)^2
Apply this rule below
x^2 - y^2 = (x + 7) - (x - y)

Which angle is an exterior angle?

Answers
Among angles i , k , g , a ,i and k are the exterior angles.
Given i°, k° ,g° ,a° are some angles and we have to find which angle is exterior angle.
The angle between a side of a polygon and an extended side is known as exterior angle of polygon. The sum of exterior angles of a polygon is equal to 180 degrees. We have to identify exterior angles among i° ,k° ,g° ,a°.
The angle i is an exterior angle because it is formed on a line opposite to angle d.
Angle k is also an exterior angle because it is also formed on opposite side of an angle.
Angle g is not an exterior angle.
Angle a is not an exterior angle.
Hence i and k are exterior angles among i, g, k, a.

a) 822.

What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
Then, the margin of error is given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.We have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
Item a:
The estimate is of [tex]\pi = 0.26[/tex], hence we solve for n when M = 0.03.
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.96\sqrt{\frac{0.26(0.74)}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.96\sqrt{0.26(0.74)}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.26(0.74)}}{0.03}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{1.96\sqrt{0.26(0.74)}}{0.03}\right)^2[/tex]
n = 821.2
Rounding up, a sample of 822 is needed.
Item b:
No prior estimate, hence [tex]\pi = 0.5[/tex], which is when the largest sample size is needed.
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.96\sqrt{0.5(0.5)}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.5(0.5)}}{0.03}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{1.96\sqrt{0.5(0.5)}}{0.03}\right)^2[/tex]

Divide name and write the answer under it.
look for another number that can divide those answers you got. but they aren't no numbers that can divide them without remainders anymore, so you divide 2 by 2 and write down 1 and just write down the 3 back .

Answer: [tex]x\sqrt[9]{y^{2} }[/tex]
Step-by-step explanation: For all expressions in the form [tex]x^{\frac{a}{b}[/tex] , the expression is equal to [tex]\sqrt[b]{x^a}[/tex]. The denominator in a fractional exponent is the type of root it is. For example, [tex]x^\frac{1}{3}[/tex] is going to be the cubed root, or the
3rd root of x ([tex]\sqrt[3]{x}[/tex]). The numerator is what power x is raised to. For example, [tex]x^\frac{3}{2}[/tex] is going to be [tex]\sqrt{x^3}[/tex].
In fractional exponents, the square root only takes the form of the variable it is assigned to. What does that mean? Well, for [tex]xy^\frac{2}{9}[/tex], the square root only applies to the y. The x is considered a constant and can be moved out. Thus, we get [tex]x\sqrt[9]{y^2}[/tex].
