Joseph owes his older brother $15, so he has a balance of -$15 with his brother . Joseph borrows more money from his brother ,bringing his balance to 5 times of the previous amount what is Joseph's new balance with his brother
Final answer:
Joseph's new balance, after borrowing more money which equals 5 times his initial debt of $15, is -$75.
Explanation:
Joseph initially owes his older brother $15, which can be represented as a balance of -$15. If Joseph's new balance is 5 times the previous amount, we would perform the following calculation:
Previous balance x 5 = New balance
So we would multiply -$15 by 5:
-$15 x 5 = -$75
Therefore, Joseph's new balance with his brother is -$75.
What is the area of the shaded region in the diagram? Use the value `pi` = 3.14, and round your answer to two decimal places.
Answer:
Can you attach a picture of the diagram?
Step-by-step explanation:
Answer:
9.42 Square Units
How:
You need to use the sector area formula.
Sector Area = Measure of Arc / 360° × π r²
So then you just plug in the numbers:
Sector Area = 45° / 360° × π 5²
Sector Area = 1/8 × 25π
Sector Area = 9.817477
Sector Area = 45° / 360° × π 7²
Sector Area = 1/8 × 49π
Sector Area = 19.242255
Then all you have to do is subtract them both to find the area.
19.242255 - 9.817477 = 9.42 Square Units

You need to know the 30-60-90 triangles rules for lengths. (b, b√3, 2b)
the given side length of corresponds to the 30° angle. So, b = 8
side y corresponds to the 60° angle so it is b√3. Since we determined that b = 8, then b√3 is 8√3.
side x corresponds to the 90° angle so it is 2b. Since we determined that b = 8, then 2b = 2(8) = 16
Answer: x = 16, y = 8√3

True or false? The circumcenter of a triangle is the center of the only circle that can be circumscribed about it
Answer:
The statement is true.
Step-by-step explanation:
Given the statement we have to tell the statement is true or false.
The statement is
"The circumcenter of a triangle is the center of the only circle that can be circumscribed about it"
The circumcenter of triangle is the point in the triangle where the perpendicular bisectors of sides intersect.
The center of the circumscribed circle is the the point where the perpendicular bisectors of the sides meet.
Hence,
The circumcenter is also center of the triangle's circumcircle - the circle that pass through all three of the triangle's vertices.
Therefore, the given statement is true.
Answer:
True
Step-by-step explanation:
Circumcircle: A circle drawn outside a circle is called circumcircle and its center is called circum-center.
Circum-center of triangle:It is the point where the perpendicular bisectors of a triangle intersect.
The circumcenter of triangle is also the center of triangle's circumcircle.
The circumcenter is equidistant from each vertex of the triangle.
The circumcenter of right triangle falls on the side opposite the right triangle.
Hence, the circumcenter of a triangle is the center of the only circle that can be circumscribed about it.

Person who answered: BangtanBoyScouts
Answer: The correct option is
(C) [tex]y=\dfrac{2}{3}x-2.[/tex]
Step-by-step explanation: We are given to select the equation of a line in slope-intercept form with slope [tex]\dfrac{2}{3}[/tex] and y-intercept at (0, -2).
We know that
the slope-intercept form of the equation of a line with slope m and y -intercept at the point (0, c) is given by
[tex]y=mx+c.[/tex]
For the given line, we have
[tex]\textup{slope, }m=\dfrac{2}{3},\\\\\\\textup{y-intercept},~(0,c)=(0,-2)\\\\\Rightarrow c=-2.[/tex]
Therefore, the equation of the line in slope-intercept form is
[tex]y=mx+c\\\\\Rightarrow y=\dfrac{2}{3}x+(-2)\\\\\\\Rightarrow y=\dfrac{2}{3}x-2.[/tex]
Thus, the required equation of the line in slope-intercept form is [tex]y=\dfrac{2}{3}x-2.[/tex]
Option (C) is CORRECT.
The graph models the function f(x) = 2(1/2)x. What is the domain and range of the function?
A-Domain: x < 0; Range: y > 0
B-Domain: x > 0; Range: all real numbers
C-Domain: all real numbers; Range: y > 0
D-Domain: all real numbers; Range: y ≥ 0
Please explain with the answer !!
Hello!
Given the function, [tex]f(x) = 2(\frac{1}{2})^{x}[/tex], notice that the function f(x) is an exponential function.
All exponential functions have a horizontal asymptote at y = 0, and this means that the graph never goes over the line y = 0. Therefore, the range is less than zero, but never equal to zero.
Also, this means that the domain of the function f(x) is all real numbers because as we substitute positive x-values into the function, the graph goes closer to zero, but never across zero. But, if we substitute negative x-values into the equation, it goes to infinity.
Therefore, the answer is choice C. The domain of f(x) is all real numbers, and the range is y > 0.
We want to find the domain and range of the given equation.
We will see that the correct option is C:
Domain: all real numbers;
Range: y > 0
First, we need to define what these are.
For a given function y = f(x), the domain is the set of all the possible x-values we can input on the function, and the range is the set of the possible outcomes.
We have the exponential equation:
f(x) = 2*(1/2)^x
To get the domain we start by assuming that the domain is the set of all real numbers, and then we see if the equation has a problem for a given value of x, then we remove that from the domain.
But here we have x on the exponent, so there are no value of x that causes problems, thus the domain is the set of all real numbers.
To get the range we can look at the graph, we can see that the range goes from near 0 to infinity, so we can say that:
range = y > 0.
(note that the function tends asymptotically to zero, meaning that it never becomes equal to zero).
Then the correct option is C:
Domain: all real numbers;
Range: y > 0

Given the following perfect square trinomial, fill in the missing term.
x2 − 16x + ____
Answer:
[tex]x^{2}-16x+64[/tex]
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have the following perfect square trinomial given in the problem:
[tex]x^{2}-16+[/tex]
2. To fill the missing term, you must divide the coefficient -16 by 2 and then you must square it, as following:
[tex](\frac{-16}{2})^{2}=(-8)^{2}=64[/tex]
Complete the square to transform the quadratic equation into the equation form (x – p)2 = q. x2 + 14x + 34 = 5
(x + 7)² = 20
subtract 34 from both sides
x² + 14x = - 29
add (half the coefficient of the x- term )² to both sides
x² + 2(7)x + 49 = - 29 + 49
(x + 7)² = 20

A company sells lab equipment. The daily revenue and costs are modeled by the functions below where x is the number of units sold.
Pleeeeaaasssseeeee help! <3 I'm just trying to graduate.thanks.
Subtract the cost from the revenue:
(-0.32x^2+270x) - (70x+52)
270x - 70x = 200x
The answer would be -0.32x^2 + 200x + - 52
Answer:
P(x) = -0.32x² + 200x + (-52)
Step-by-step explanation:
A company sells lab equipment. Daily revenue and costs are modeled by the function as given in the question.
Revenue: R(x) = -0.32x² + 270x
Cost : C(x) = 70x + 52
Here x = Number of units sold.
Now we have to determine the function P(x) for daily profit.
Since Profit = Revenue - Cost
P(x) = R(x) - C(x)
P(x) = (-0.32x² + 270x) - (70x + 52)
= -0.32x² + 270x - 70x - 52
P(x) = -0.32x² + 200x - 52
Therefore, answer will be P(x) = -0.32x² + 200x + (-52)

Representative: "We will match any competitive offer. Your adjusted rate will be __________ dollars per month."
Given my current rate = $129.00 per month.
Savings of 15% over your prices.
Therefore, saving = 15% of $129.00 = 0.15 × 129.00 =$19.35.
Adjusted rate = current rate - saving = 129 - 19.35 = $109.65
Therefore, We can rewrite above expression as :
My current rate is $129.00 per month." Representative: "We will match any competitive offer. Your adjusted rate will be 109.65 dollars per month."
If my current rate is $129.00 per month. Your adjusted rate will be $109.65 dollars per month.
Adjusted rateUsing this formula
Adjusted rate = Current rate - Adjustment
Where:
Current rate=$129
Adjustment=(15%×$129)
Let plug in the formula
Adjusted rate=$129-(15%×$129)
Adjusted rate = $129 - $19.35
Adjusted rate =$109.65 per month
Inconclusion your adjusted rate will be $109.65 dollars per month.
