locate y = - 4 on the y- axis. then a horizontal line through y = - 4 intersects the curve at x = - 2 and x = 1
----------------------------------------------------------
the axis of symmetry is a vertical line through the vertex with equation
x = c ( c is the value of the x- coordinate of the vertex )
vertex = ( - [tex]\frac{1}{2}[/tex], - 6 )
equation of axis of symmetry is x = - [tex]\frac{1}{2}[/tex]
------------------------------------------------------------
the minimum value is the y- coordinate of the vertex
that is the minimum value of f(x) is - 6
------------------------------------------------------------
given a parabola in standard form
ax² + bx + c ( a ≠ 0 )
• if a > 0 then graph opens up
• if a < 0 then graph opens down
Here the graph opens up , then coefficient of f(x) is positive
-------------------------------------------------------------
the solutions to f(x) = 0 are the values of x on the x- axis where the graph crosses.
the solutions are x = 2 and x = - 3

The first term of a geometric sequence is 2, and the 4th term is 250. Find the 2 terms between the first and the 4th term.
Answers
Answer:
second term: 10
third term: 50
Step-by-step explanation:
The equation for any geometric sequence is [tex]a_{n} = a_{1} *r^{n-1}[/tex] where n is the term number you want to find, [tex]a_{1}[/tex] is the first term in the sequence, and [tex]r[/tex] is the common ratio.

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options.
x2 + (y – 3)2 = 36
x2 + (y – 5)2 = 6
(x – 4)² + y² = 36
(x + 6)² + y² = 144
x2 + (y + 8)2 = 36
Answers
A correct answer is option A which is x² + (y – 3)² = 36 is the equation of the circle that has a diameter of 12 units and a center that lies on the y-axis.
What is a circle?A circle is a two-dimensional geometry on the plane having a center point and the circular line is drawn equidistant from the center point.
The general form of the equation of a circle is given as:-
( x - h )² + ( y - k )² = r²
By comparing the given equation we can see the following results:-
x² + (y – 3)² = 36
( x - ( 0 ))² + ( y - 3 )² = 6²
We can see that the coordinate of the center are ( 0, 3 ) and the radius is 6 so the diameter is 12.
Therefore the correct answer is option A which is x² + (y – 3)² = 36 is the equation of the circle that has a diameter of 12 units and a center that lies on the y-axis.

A tub of water is emptied at a rate of 3 gallons per minute. The equation y –12 = –3(x – 1) models the amount of water remaining, where x is time (in minutes) and y is the amount of water left (in gallons). Analyze the work shown below to determine the initial amount of water.
1. Solve for the y-variable.
y – 12 = –3(x – 1)
y – 12 = –3x + 3
y = –3x +15
2. Write the equation using function notation.
f(x) = –3x +15
The tub started with
gallons of water.
Answers
The initial amount of the water is 15 gallons
Linear functionsThese are functions that has a leading degree of 1. Given the equation that represents the amount of water remaining after x minutes;
y - 12 = -3(x- 1)
y -12 = -3x + 3
y = -3x +3 + 12
y = -3x + 15
In order to determine the initial amount of water, we will substitute x =0 into the function
y = -3(0) + 15
y = 15
Hence the initial amount of the water is 15 gallons

Casho invests money in an account paying simple interest. She invests $30 and no
money is added or removed from the investment. After one year, she has $32.40.
What is the simple percent interest per year?
Answers
Answer:
8%
Step-by-step explanation:
Divide ( 32.40 / 30 ). This outputs the answer 1.08, or 108%. This means that the outcome is 108% of the original, or 8% greater.
The simple interest in which Casho invests money was 8%.
What is simple interest?
Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.
We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Given, p = 30, SI = (32.40 - 30) = $2.40 and t = 1.
Therefore, 2.40 = (30×r×1)/100.
240 = 30r.
r = 240/30.
r = 24/3.
r = 8.
So, The rate of simple interest is 8%.

Using a geometric sequence, it is found that the approximate value of the car at the end of the 10th year will be given by:
A. $6,974.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem, the first term and the common ratio are given, respectively, by:
[tex]a_1 = 18000, q = \frac{16200}{18000} = 0.9[/tex]
Hence the equation is:
[tex]a_n = 18000(0.9)^{n-1}[/tex]
At the end of the 10th year, the value will be of:
[tex]a_{10} = 18000(0.9)^{10-1} = 6974[/tex]

Find the center and radius of the circle with this equation:
x² + 16x + 64 + y² - 2y + 1 = 144
Answers
By completing squares, we will see that the radius is 12 units and the center is (-8, 1).
How to find the center and radius of the circle?The circle of center (x₁, y₁) and radius r is written as:
(x - x₁)² + (y - y₁)² = r²
Now we go to our equation:
x² + 16x + 64 + y² - 2y + 1 = 144
Now we need to complete squares:
(a + b)² = a² + 2ab + b²
Then we can rewrite:
(x² + 2*8*x + 8*8) + (y² - 2y + 1) = 12²
(x + 8)² + (y - 1)² = 12²
So the center is the point (-8, 1) and the radius is 12 units.

When s is less than 4, (s - 4) will be negative and the square root is undefined in real numbers.
The denominator or bottom line is defined for all real values EXCEPT s = 4.
When s = 4 you will be dividing by zero which is undefined.
Taking these together f(s) is defined for all values of s greater than 4.
Therefore the domain for real numbers is s > 4
The domain for complex numbers is s <> 4 because square roots of negatives exist in that set.

The indicated side of the right triangle is [tex]44\sqrt{2} =\frac{88}{\sqrt{2} }[/tex].
RIGHT TRIANGLEA triangle is classified as a right triangle when it presents one of your angles equal to 90º. The greatest side of a right triangle is called hypotenuse. And, the other two sides are called cathetus or legs.
The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.
The Pythagorean Theorem says:[tex]hypotenuse^2=(leg_1)^2+(leg_2)^2[/tex]. And the main trigonometric ratios are:
[tex]sin(\beta )= \frac{opposite\;leg}{hypotenuse} \\ \\ cos(\beta )= \frac{adjacent\;leg}{hypotenuse} \\ \\ tan(\beta )= \frac{opposite\;leg}{adjacent\;leg} \\ \\[/tex]
The question asks to find one of the legs (y). Then, you can find y applying the trigonometric ratio (sin 45°).
[tex]sin(45\°)=\frac{y}{88}[/tex]
Like sin45° is equal to [tex]\frac{\sqrt{2} }{2}[/tex], you have
[tex]\frac{\sqrt{2} }{2} =\frac{y}{88}\\ \\ 2y=88\sqrt{2} \\ \\ y=44\sqrt{2} \\ \\ Thus\\ \\ y=\frac{88}{\sqrt{2}}[/tex]
