The time the fleet may leave the Manilow Bay given the rate at which the depth rises is 9am.
What time may the fleet leave?The fishing fleet would leave when the water level reaches 32. At 5 am, the water level is 27 feet. The water level needs to rise 6 more feet (32 - 27) before the fleet can leave.
In order to determine the time, divide 6 feet by the rate at which the tide rises. Division is the mathematical operation that is used to determine the quotient of two or more numbers.
Hours when the tide would rise 6 feet = 6 ÷ 1 1/2
6 x 2/3 = 4 hours
Add 4 hours to 5am : 5am + 4 = 9am

The measures of the triangle's unknown angles will be 50° and 100°.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
A triangle has one 30° angle, an unknown angle, and an angle with a measure that is twice the measure of the unknown angle.
Let 'a' and 'b' be the unknown angles of the triangle. Then the equation will be
∠a = 2 ∠b
We know that the angle sum of the triangle is 180°. Then the equation will be
∠a + ∠b + 30° = 180°
2∠b + ∠b = 150°
3∠b = 150°
∠b = 50°
Then the measure of the angle 'a' will be
∠a = 2 ∠b
∠a = 2 x 50°
∠a = 100°
The measures of the triangle's unknown angles will be 50° and 100°.

The equation of the CD in slope-intercept form is: C. y = -4x + 2.
How to Write an Equation in Slope-intercept Form?The equation of a line in slope-intercept form can be written as y = mx + b. In this form, m represents the slope and b represents the y-intercept.
The slopes of lines that are parallel are equal, while the slopes of the lines that are perpendicular to each other are negative reciprocals of each other.
The slope (m) of the graph y = 1/4x - 3 is 1/4. Since AB of rectangle ABCD is perpendicular to the graph, then the slope (m) of AB would be the negative reciprocal of 1/4 which is: -4.
Also, since CD is parallel to AB, they would have the same slope, m = -4.
To find the equation of CD that is parallel to AB, substitute m = -4 and (a, b) = (-1, 6) into y - b = m(x - a):
y - 6 = -4(x - (-1))
y - 6 = -4(x + 1)
y - 6 = -4x - 4
y = -4x - 4 + 6
y = -4x + 2
Therefore, the equation of the CD in slope-intercept form is: C. y = -4x + 2.

Select correct answer from the drop-down menu. Charlie stands at point while holding the control line attached to a model airplane. The plane travels 120 feet counterclockwise from point to point . About how long is the control line? A circle with center point A. C and B are points on the circle. A line connects AC and AB. The angle of A is 80 degrees. The control line is about feet long.
The 120 feet point to point displacement and the 80° angle formed at the vertex A by the control line, AC = AB, Charlie is holding, gives the length of the control line as about 93 feet.
How can the length of the control line be calculated?The given parameters are;
The distance (displacement) traveled by the plane = 120 feet (point to point)
The points on the circle, flown by the model plane = C and B
The center of the circle = A
The angle formed by AC and AB = 80°
Required;
The length of the control line.
Solution:
The control line in the description of the diagram is the line AC or AB
Therefore;
AC = AB
Taking the points C and B as the point the plane flew through, we have;
BC = 120 feet
Which gives
‹ABC = ‹ACB = (180° - 80°)/2 = 50°
From the law of sines, we have;
BC/(sin(A)) = AC/(sin(‹ABC))Which gives;
120/(sin(80°)) = AC/(sin(50°))

x . Write the value of the variable.
B is between A and C
AB=4x-7
BC=20x-5 and
AB=BC
Using the given information, the value of the variable x is equal to -0.125.
The given question can easily be solved using the constraints given in the question. It is given that B is between A and C. Also, the given question is in the form of Linear equation in one variable. Linear equation in one variable is the one which is of the form ax+b=0 where a and b are real numbers and x is the variable.

What is a complex number?A Complex number is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
We have a function as x⁴+ x² = 4 x² + 4
x⁴+ x² - 4 x² - 4 = 0
x⁴+ - 3 x² - 4 = 0
Assume u = x²
x⁴+ - 3 x² - 4 = 0
Now using the substitution u = x² , then
u² - 3u - 4= 0 ← in standard form
(u - 4)(u + 1) = 0 ← in factored form
Then equate each factor to zero and solve for u
u - 4 = 0 ⇒ u = 4
u + 1 = 0 ⇒ u = - 1
Then convert u back into terms of x
x² = 4 ( take square root of both sides )
x = ± 2
x² = - 1 ( take square root of both sides )
⇒ x = ±i
Thus, The roots of the function x⁴+ x² = 4 x² + 4 are ±2 or x = ±i.

Carol buys last year's best-selling novel, in hardcover, for $25.50. This is with a 15% discount from the original price. What was the original price of the novel?
Answer:
$30.00
Step-by-step explanation:
$25.50 = y(1 - 0.15)
$25.50 = y(0.85)
($25.50) / (0.85) = y
y = $30
Answer:
$30
Step-by-step explanation:
let x = the original price
x - .15x = 25.50
The original price - .15 of the original price is 25.25
.85x = 25.25 Divide both sides by .85
x = 30

[tex](x-6)^2=-1[/tex]
Step-by-step explanation:
Given equation:
[tex]-6x^2+64x-222=-8x[/tex]
When completing the square, first move the terms in x to the left and the constant to the right of the equation:
[tex]\implies -6x^2+64x-222=-8x[/tex]
[tex]\implies -6x^2+64x-222+222=-8x+222[/tex]
[tex]\implies -6x^2+64x=-8x+222[/tex]
[tex]\implies -6x^2+64x+8x=-8x+222+8x[/tex]
[tex]\implies -6x^2+72x=222[/tex]
Factor out the leading coefficient -6 from the left side, then divide both sides by -6:
[tex]\implies -6(x^2-12x)=222[/tex]
[tex]\implies \dfrac{-6(x^2-12x)}{-6}=\dfrac{222}{-6}[/tex]
[tex]\implies x^2-12x=-37[/tex]
Add the square of half the coefficient of the term in x to both sides, forming a perfect square trinomial on the left side:
[tex]\implies x^2-12x+\left(\dfrac{-12}{2}\right)^2=-37+\left(\dfrac{-12}{2}\right)^2[/tex]
[tex]\implies x^2-12x+\left(-6\right)^2=-37+\left(-6\right)^2[/tex]
[tex]\implies x^2-12x+36=-37+36[/tex]
[tex]\implies x^2-12x+36=-1[/tex]
Factor the perfect square trinomial on the left side:
[tex]\implies (x-6)^2=-1[/tex]
To solve:
[tex]\implies \sqrt{(x-6)^2}=\sqrt{-1}[/tex]
[tex]\implies x-6=\pm i[/tex]
[tex]\implies x-6+6=\pm i+6[/tex]
[tex]\implies x=6 \pm i[/tex]
Therefore, the solutions are:

Answer:
The first option
Step-by-step explanation:
Write an equation of a line passing through
the point (-1, 2) that is parallel to the line
y = -4x + 5
y + 1/4x - 9/4 is an equation of a line passing through the point (-1, 2) that is parallel to the line y = -4x + 5
In an equation, parallel lines have the opposite reciprocal slope. In other words, if a line's slope is a positive fraction, its reciprocal slope is negative.
Here given that y = -4x + 5
Here -4 is the slope and 5 is the y-intercept
To find a parallel line to the following equation, use the opposite reciprocal slope and point, then solve using the point-slope formula.
y - y₁ = m(x - x₁)
We have, m = 1/4, x₁ = -1 and y₁ = 2
y - 2 = 1/4(x - (-1))
y - 2 = 1/4(x + 1)
y - 2 = 1/4x + 1/4
y + 1/4x - 9/4
What is point-slope formula?
You can use the point-slope form calculator to determine the equation of a line given its slope and a point on the line. You will soon understand what the point-slope form equation is and how it differs from the slope-intercept form equation.
