Suppose a parabola has an axis of symmetry at x = -4, a maximum height of 3 and also passes through the point (–3, 0). Write the equation of the parabola in vertex form.

The quadrilateral's new coordinates will be J(4, 4), K(3, 4), L(1, 1), and M (4,1) when the procedure is applied.

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given coordinates of a quadrilateral J(-4, 4), K(-3, 4), L(-1, 1), M(-4,1)

Reflect in the x-axis

Since,

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

thus new coordinates will be,

J(-4, -4), K(-3, -4), L(-1, -1), M(-4,-1)

Rotate 180 degrees about the origin

Since,

When we rotate a figure of 180 degrees about the origin either in the clockwise or counterclockwise direction, each point of the given figure has to be changed from (x, y) to (-x, -y) and graph the rotated figure.

Thus new coordinates will be

J(4, 4), K(3, 4), L(1, 1), M(4,1)

Therefore, After applying the given operation the new coordinates of the quadrilateral will be  J(4, 4), K(3, 4), L(1, 1), and M(4,1).

Answer:

A and B

Step-by-step explanation:

You draw the points on the Cartesian plane and draw a straight line that passes through two of the drawn points, if ALL the drawn points are ON the drawn line, then it is a linear function,

If only ONE point lies outside the line, then it is NOT a linear function

The inequality that represents the interval shown on the number line is:

5 ≤ x ≤ 9

We want to use inequality notation to define the interval shown on the number line.

We can see that the first point is marked with a closed circle, at x = 5.

And then we have another closed circle at x = 9

The closed circles means that these points are solutions to the inequality, so we need to use the symbols:

≤ and ≥

Then we can write the inequality:

Answer: the probability that a student chosen at random plays the bass is 1/3 in simplest form.

Step-by-step explanation:

The probability of an event can be found by taking the number of favorable outcomes and dividing it by the total number of outcomes. In this case, we are looking for the probability that a student chosen at random plays the bass.

We know that there are a total of 6 + 4 + 7 + 2 = 19 seventh grade students and 4 + 15 + 13 + 6 = 38 eighth grade students. So there are a total of 19 + 38 = 57 students.

We also know that there are 4 seventh grade bass players and 15 eighth grade bass players, for a total of 4 + 15 = 19 bass players.

So, the probability that a student chosen at random plays the bass is 19/57. This fraction can be simplified by dividing both the numerator and denominator by their greatest common factor which is 19/57 = 1/3.

So, the probability that a student chosen at random plays the bass is 1/3 in simplest form.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that cylindrical jar contains three glass balls each has a diameter of 2cm

Let us find the volume of each sphere.

Volume of sphere=4/3×πr³

As diameter is 2 then radius is 1.

Volume of each sphere=4.186

Volume of three spheres=3×4.186=12.56

Now let us find the volume of cylinder.

The diameter of cylinder will be 2 and height is 6 cmas there are 3 spheres of diameter 2cm.

Volume of cylinder=πr²h

b) Formula for common ratio:

(see explanation below for part b)

c) [tex]a_{10} = \boxed{1024}[/tex]

d) Recursive formula: [tex]\boxed{a_{n+1} = 2a_n}[/tex]

Step-by-step explanation:

a) The common ratio r for a geometric sequence is the ratio of any term(except the first) to the previous term. And this is a constant for that sequence

If we have a sequence [tex]a_1, a_2, a_3, a_4, a_5,....\\[/tex]

[tex]r = \dfrac{a_2}{a_1} = \dfrac{a_3}{a_2} = \dfrac{a_4}{a_3} = \dfrac{a_5}{a_4}[/tex]

Here [tex]a_1[/tex] is the first term in the sequence

The sequence we have here is
2, 4, 8, 16

So
[tex]r = \dfrac{4}{2} = \dfrac{8}{4} = \dfrac{16}{8} = 2\\[/tex]
Answer to a)

------------------------------------------------------------------------------------------------------

b) This part is confusing. Are they asking for a formula for the common ratio or a formula for the nth term? You can write both or check with your teacher

The explicit formula for the common ratio is

[tex]\dfrac{a_{n+1}}{a_n} , n = 1, 2, 3, 4....\\[/tex]

The explicit formula for the nth term, [tex]a_n[/tex] of a geometric sequence is
[tex]a_n = a_1r^{n-1}[/tex]

where [tex]a_1[/tex] is the first term of the sequence and r is the common ratio
------------------------------------------------------------------------------------------------------

c)
The formula for finding the nth term of a geometric sequence is
[tex]a_n = a_1r^{n-1}\\\\[/tex]

Therefore

[tex]a_{10} = a_1 r^{(10-1)} = a_1 \times r^9\\\\[/tex]

[tex]a_1 = 2, r = 2\\\\[/tex]

So
[tex]a_{10} = 2 \cdot 2^9 \\\\= 2 \cdot 512\\\\= 1024\\[/tex]ANSWER c)

d)

A recursive formula is just an expression that denotes the relationship between one term and the next

We know that
[tex]r= \dfrac{a_{n+1}}{a_n} \\\\[/tex]

Multiplying both sides by [tex]a_n[/tex],

[tex]ra_n = a_{n+1}[/tex]

Or

[tex]a_{n+1} = ra_n\\\\[/tex]

For the specific case of r = 2 we get the recursive formula as

Answer:The price of a bond can be calculated using the formula:

Price = Maturity Value / (1 + r)^n

Where:

Maturity Value = $12,000

r = the annual interest rate as a decimal (7.25% / 100 = 0.0725)

n = the number of years to maturity (11 years)

So the price of the bond is:

Price = $12,000 / (1 + 0.0725)^11

By solving this equation we get the price of bond is $7,065.87 approximately.

Note: The bond price is the amount you pay to buy the bond and receive the maturity value at the end of the bond term.

The ordered pairs that satisfies the linear inequality x < - 3 are (-4, -3) and (-3, -3)

A linear inequality is a mathematical statement that describes a relationship between two or more variables that are not necessarily equal. It is similar to a linear equation, but instead of an equal sign, it uses one of the inequality signs: <, >, ≤, or ≥.

A linear inequality can also be represented graphically on a coordinate plane, by shading the region of the plane that satisfies the inequality. The solution set of a linear inequality is the set of all points that make the inequality true.

A linear inequality can also have infinitely many solutions, no solution or a unique solution. The solution set will be a region in a coordinate plane which is a half-plane, a line or a point depending on the inequality.

In the problem, the inequality x < -3 will have an ordered pair of solution of

(-∞, -3).

This implies that all values of x must lies from negative till infinity while y lies up to - 3.

Answer: 1 + 2x

Step-by-step explanation:

To solve this problem, it's helpful to understand "order of operations." The order is: parentheses, exponents, multiplication, division, addition, and lastly, subtraction.

A helpful mnemonic is PEMDAS. I was taught "Parachute Expert My Dear Aunt Sally" to help remember the order.

We must work with the numbers inside the parantheses, since "parantheses" is the first operation. We'll start with the first paranthesis: (-5x2 + 10x - 12).

Since there are no exponents in this equation, we can go to the third operation: multiplication. (I like to use the "·" symbol to show that two numbers are multiplied because it's easy for me to confuse the letter X with "x" when it is used as a multiplication symbol).

-5 · 2 = -10

Two negative numbers are added, so -10 and -12 = -22

This leaves (-22 + 10x)

The -22 and 10x are not added together because numbers without a letter cannot be added to numbers with letters.

Now we'll work with the second paranthesis: (-4 · 2 + 8x - 15)

-4 · 2 = -8

-8 and -15 is added to make -23

The paranthesis now looks like:

(-23 + 8x)

Notice that there is a negative sign outside of the second paranthesis in the equation.

(-22 + 10x) − (-23 + 8x)

When a number or symbol is outside of a paranthesis, that number or symbol is multiplied across everything within the parantheses.

Now, it is:

(23 - 8x)

All of the numbers can be taken out of the parantheses now:

-22 + 10x + 23 - 8x

-22 + 23 = 1

10x - 8x = 2x

The final answer:

1 + 2x

2 × 10³ is an exponential expression, which has a standard form as 2000.

Exponential expressions are just a way to write powers in short form. The exponent

indicates the number of times the base is used as a factor. So in the case of 32 it can

be written as 2 × 2 × 2 × 2 × 2 = 25, where 2 is the “base” and 5 is the “exponent”.

The expanded form comes in a variety of forms. Exponents are employed. The expanded form of that expression is what is stated above.

One more makes use of multipliers like 1, 10, 100, 1000, and so forth. The expression broadens in that form as...

10^2 = 1×100

Another expanded form uses the expanded form's individual digits, setting the others to zero.

10^2 = 100

The standard format is...

10^2 = 100.

Thus, 2 × 10³ is an exponential expression, which has a standard form as 2000.
