Answer:
B. $6,870
Step-by-step explanation:
Calculate how much money they earned from tickets then subtract the cost of making and that's their balance:
(1007×10)-3200=
10070-3200=
$6,870
B. $6,870
Final answer:
After calculating the total proceeds from selling tickets to 1,007 attendees at $10 each, the balance of the line of credit used to fund the play's production ($3,200) will be a positive $6,870.
Explanation:
The question pertains to a fundraiser calculation for Betsy's high school play. To determine the balance of the bank account after ticket sales, we must calculate the total proceeds from selling tickets to the attendees and then adjust the balance of the line of credit that was originally used to fund the production.
The production cost is $3,200.00, and tickets are sold at $10 each. With 1,007 people attending, the total ticket proceeds will be 1,007 imes $10 = $10,070. Since the school used a line of credit to pay for the play, the proceeds will pay off this balance. Hence, after depositing the ticket sales, the balance is:
Balance after deposit = Ticket proceeds - Production costs
= $10,070 - $3,200
= $6,870 (Credit balance)
The correct balance of the bank account after the play's opening night is therefore $6,870 (Option B).

Write an equation that is perpendicular to y=4x- 10 and goes through the point (4,2)
Answer:
y = (-1/4)x + 3
Step-by-step explanation:
The slope of our equation is 4, so to find the slope of the perpendicular equation, we have that:
m1 * m2 = -1
Where m1 is the slope of the first equation and m2 is the slope of the perpendicular equation.
So, we have that:
4 * m2 = -1
m2 = -1/4
So the second equation is y = (-1/4)x + b
If the second equation goes through the point (4,2), for x = 4 we have y = 2, then:
2 = (-1/4)*4 + b
2 = -1 + b
b = 3
So the perpendicular equation is:
y = (-1/4)x + 3

A circle has the equation x2−12x+27=−y2+8y.
What is the equation of the circle in standard form, the location of its center, and the length of its radius?
The equation of the circle is (x−6)2+(y−4)2=25; the center is at (6,4), and the radius is 5 units.
The equation of the circle is (x−6)2+(y−4)2=5; the center is at (6,4), and the radius is 5–√ units.
The equation of the circle is (x−6)2+(y−4)2=5; the center is at (−6,−4), and the radius is 5–√ units.
The equation of the circle is (x−6)2+(y−4)2=25; the center is at (−6,−4), and the radius is 5 units.
Answer:
It's the first option.
Step-by-step explanation:
x^2 - 12x + 27 = - y^2 + 8y
x^2 - 12x + y^2 - 8y = -27 Completing the squares:
(x - 6)^2 - 36 + (y - 4)^2 - 16 = -27
(x - 6)^2 + (y - 4)^2 = -27 + 36 + 16
(x- 6)^2 + (y - 4)^2 = 25 is the standard equation.
The center is at (6, 4) and the radius is 5 units.
Answer:
first option
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² - 12x + 27 = - y² + 8y ( subtract - y² + 8y from both sides )
x² - 12x + y² - 8y + 27 = 0 ( subtract 27 from both sides )
x² - 12x + y² - 8y = - 27
Using the method of completing the square on both the x and y terms
add ( half the coefficient of the x/ y term )² to both sides
x² + 2(- 6)x + 36 + y² + 2(- 4)y + 16 = - 27 + 36 + 16
(x - 6)² + (y - 4)² = 25 ← in standard form
with centre = (6, 4 ) and r² = 25 ⇒ r = [tex]\sqrt{25}[/tex] = 5 → first option
Solve x :
[tex]{(3 {x}^{2} - 8x + 5)}^{x + 1} = 1[/tex]
We want this expression to fall in one of the two cases:
[tex]\alpha ^ 0 = 1 = 1^\beta[/tex]
So, if the exponent is zero, the base can assume any value, because everything (expect zero) to the power of zero is one.
Similarly, if the base is 1, the exponent can be any number, becuase 1 raised to any exponent is still one.
If we are looking for the "zero exponent" strategy, we simply have to impose
[tex]x+1=0\iff x=-1[/tex]
In this case, the expression becomes [tex]16^0=1[/tex], so we avoided the [tex]0^0[/tex] case and we're good.
If we are looking for the "base equals one" strategy, we must impose
[tex]3x^2-8x+5 = 1 \iff 3x^2-8x+4=0 \iff x=\dfrac{2}{3}\lor x=2[/tex]
Answer:
x = -1, ⅔, 2
Step-by-step explanation:
3x² - 8x + 5
3x² - 3x - 5x + 5
3x(x - 1) - 5(x - 1)
(3x - 5)(x - 1)
[3x² - 8x + 5]^(x+1) = 1
The ourput is 1 when:
1) The power is 0
x + 1 = 0
x = -1
2) base is 1
3x² - 8x + 5 = 1
3x² - 8x + 4 = 0
3x² - 6x - 2x + 4 = 0
3x(x - 2) - 2(x - 2) = 0
(3x - 2)(x - 2) = 0
x = 2 , ⅔
Therefore, 3 solutions
x = -1, ⅔ , 2

3.Can we multiply a 2x3 matrix by a 3x2 matrix? If yes, what dimensions will the product matrix AB have ?
Answer:
Yes, the dimensions will be 2x2
Step-by-step explanation:
When multiplying matrices you have AxB by CxD. You can only multiply matrices if the inner number is the same.
Ex. 2x3 by 3x2 or QxD by DxW
The dimensions of the result will depend on the outer numbers.
Ex. 2x3 by 3x2 has a 2x2 result or QxD by DxW has a QxW result
Yes, you can multiply a 2x3 matrix by a 3x2 matrix. The result will be a 2x2 matrix because the number of rows in the first matrix and the number of columns in the second matrix define the dimensions of the product matrix.
Explanation:Yes, it is possible to multiply a 2x3 matrix by a 3x2 matrix. When multiplying matrices, the number of columns in the first matrix must be the same as the number of rows in the second matrix. Therefore, in this case, where we have a 2x3 matrix and a 3x2 matrix, the 3 columns in the first matrix and the 3 rows in the second matrix make multiplication possible.
The resulting product from the multiplication of these two matrices will be a new matrix whose dimensions are determined by the number of rows in the first matrix and the number of columns in the second matrix. In this case, as the first matrix has 2 rows and the second matrix has 2 columns, the resulting matrix will have dimensions of 2x2.

Find the value of r in the following diagram.
The value of r is 3.75 from the diagram.
We have to find the value of r which is a radius.
ABC is a right angle triangle in the circle.
We find the value of r by using pythagoras theorem.
r²+9²=(6+r)²
r²+9²=36+12r+r²
9²=36+12r
81=36+12r
Subtract 36 from both sides:
81-36=12r
45=12r
Divide both sides by 12:
r=45/12
r=3.75
Hence, the value of r is 3.75.
