Answer:
[tex]a_{n}[/tex] = 1.3n - 4.7
Step-by-step explanation:
There is a common difference d between consecutive terms
d = - 2.1 - (- 3.4) = - 0.8 - (- 2.1) = 0.5 - (- 0.8) = 1.8 - 0.5 = 1.3
This indicates the sequence is arithmetic with nth term ( explicit rule )
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 3.4 and d = 1.3 , then
[tex]a_{n}[/tex] = - 3.4 + 1.3(n - 1) = - 3.4 + 1.3n - 1.3 = 1.3n - 4.7
A recursive rule allows a term in the sequence to be found by adding d to the previous term, that is
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 1.3 : a₁ = - 3.4

You decide that you want to make a lighter purple paint. You make the new mixture by adding 1/4 cup of white paint for every 1/4 cup of red paint and 1/2 cup of blue paint. How much red paint, blue paint, and white paint do you use to make 1 1/2 gallons of the lighter purple paint?
Answers
Answer:
Cups of white paint = 24 * 1/4 = 6 cups
Cups of red paint = 24 * 1/4 = 6 cups
Cups of blue paint = 24 * 1/2 = 12 cups
Step-by-step explanation:
1/4 cup of white paint is added for every :
1/4 cup of red paint and 1/2 cup of blue paint :
1 gallon = 16 cups
1 1/2 gallons = 16 + 8 = 24 cups
To make 1 cup of lighter purple paint ;
1/4 cup of white + 1/4 cup of red + 1/2 cup of blue
Therefore ;
To make 24 cups of lighter purple paint :
Cups of white paint = 24 * 1/4 = 6 cups
Cups of red paint = 24 * 1/4 = 6 cups
Cups of blue paint = 24 * 1/2 = 12 cups

A parabola can be drawn given a focus of (1, 10) and a directrix of
y = 4. What can be said about the parabola?
Answers
Answer:
The parabola has an absolute minimum and its vertex is located at (1, 7).
Step-by-step explanation:
Since the directrix is below the focus, we infer that parabola has an absolute minimum, where there is a vertex, which is the midpoint of the line segment between (1, 10) and (1, 4). By definition of midpoint, we conclude that vertex is located at (1, 7).

If Sin A = .3642, find the measure of Angle A to the nearest degree.
Answers
Answer:
the measure of angle A to the nearest degree is 36°
The measure of angle A to the nearest degree is 21°.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
We can use the inverse sine function (denoted as sin⁻¹ or arcsin) to find the measure of angle A:
sin A = 0.3642
Taking the inverse sine of both sides, we get:
A = sin⁻¹(0.3642)
Using a calculator, we get:
A ≈ 21.3°
Rounding to the nearest degree, we get:
A ≈ 21°
Therefore,
The measure of angle A to the nearest degree is 21°.

Recuerda contestar todas las partes de la pregunta en el espacio provisto.

Respuesta:
P = 16; Q = 24
P = 0; Q = 0
Explicación paso a paso:
Dada la relación:
8 (2x + 3) = Px + Q
Abra el soporte
16x + 24 = Px + Q
Los valores de P y Q para los que la ecuación tiene infinidad de solución:
Px = 16x
Q = 24
Por tanto, en P = 16; Q = 24, la ecuación tiene infinidad de soluciones.
Valores de P y Q para los que la ecuación no tiene solución:
Px = 0; P = 0
Q = 0
Por tanto, los valores de P y Q para los que la ecuación no tiene solución es 0

Step-by-step explanation:
Here we're being asked to find the roots of this quadratic equation.
Set f(x) = 3(x² - 11x + 24 = 0.
This factors into f(x) = 3(x - 8)(x - 3) = 0.
Then x - 8 = 0 and x - 3 = 0, yielding x = 8 and x = 3. These correspond to the points (8, 0) and (3, 0).

Which graph does not represent a function
Answers
Answer:
The graph that does not represent a function is;
The first graph of the circle
Step-by-step explanation:
A function is a relationship, rule or law that maps the inputs 'x' the input set 'X' known as the domain, to exactly one output 'y' in the output set 'Y' known as the range
Therefore, a function maps an input to exactly one output
In a graph, the inputs are usually the x-variables, therefore the graph that maps the x-variables (in which an x-variable has) to more than one y-variable is the graph of the circle
In the graph of the circle, we have;
When x = 0 at the origin, y = 0
Similarly
When x = 0 at the maximum point, y = 4
Therefore, the graph of the circle does not represent a function.

Sameer scored better than 78% of all students taking a standardized exam. If 650 students took the exam, how many did Sameer score better than?
Answers
The interest added at the end of the year is $10, The total goal of O’Neill Raiders fundraiser is $2500 and Sameer scored better than 507 students.
What is Percentage?Percentage is the parts of a number per fraction of 100. We can divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Initial amount, P = $250
Rate of interest, r = 4% = 0.04
Interest amount = P × r × t, where t is the number of years = 1 here.
= 250 × 0.04 × 1
= $10
28% of the total fundraising goal = $700
Let x be the total fundraising goal.
28% × x = 700
0.28x = 700
x = 700 / 0.28 = $2500
Total number of students = 650
Sameer scored better than 78% of all students.
Number of students that Sameer scored better = 78% × 650
= 0.78 × 650
= 507
Hence all the answers are found.
