Answer:

3.8

Step-by-step explanation:

Hey! Let's start by assuming that these are all normal courses, and that GPA is given by the following scale:

A - 4.0

B - 3.0

C - 2.0

D - 1.0

F - 0.0

That said, this question really just involves calculating the averages.

To find the average, we add all the values together and divide the sum by the total number of values.

Therefore, our expression would look like:

(4.0 + 4.0 + 4.0 + 4.0 + 3.0)/5

This is because there are 5 total values.

Simplify:

19/5

3.8

This means your GPA would be 3.8

Answer:

The correct answer is a 3.8 GPA.

Step-by-step explanation:

Hey there!

<h2>What is the GPA scale?</h2>

The GPA scale is the scale that is used to apply grades to a cumulative grade point average. This allows for grades to be numerically represented as a culmination of your high school career.

A GPA is determined using the following scale:

A grade of 'A' earns 4 GPA points.
A grade of 'B' earns 3 GPA points.
A grade of 'C' earns 2 GPA points.
A grade of 'D' earns 1 GPA point.
A grade of 'F' earns no GPA points.

Your GPA is determined by finding out how many GPA points you have earned overall by using an additive operation.

If you have 4 A's, you can multiply 4 by the number of GPA points that are associated with a grade of 'A' on the GPA scale.

$4 \times 4 = 16$

Since you earned a B, you would then add 3 points to the product you just received.

$16 + 3 = 19$

Then, you will divide this total by the number of courses taken.

$\displaystyle \frac{19}{5} = 3.8$

Therefore, your final GPA is a 3.8 on a 4.0 GPA scale.

This answer was calculated on the assumption that each course was equivalent to one credit.

What is the length of ac help pls

Lelu [443]

Answer:

x=2

Step-by-step explanation:

This is an isosceles triangle you can tell by the two congruent/equal angles

angle A is congruent/equal to angle C by definition the two sides will be equal.

x-4=3x-8

1. get all you x's on one side. by subtracting x from both sides you don't have to deal with dividing by negatives later on.

x-x-4=3x-x-8

-4=2x-8

now you want to get x by itself so add 8 to both sides

4= 2x

x is still not by itself so divide both sides by 2

x=2

CUALES SON LOS GRADOS PARA HACER UNA GRAFICA DE PASTEL, CON LOS SIGUIENTES PORCENTAJES( 20%,50%,10%)

svlad2 [7]

Answer:

Lo primero que debemos saber, es que la gráfica de pastel nos permite dividir a una población, la cual sería el 100%, en porcentajes menores que representan algo.

En este caso tenemos los porcentajes 20%, 50%, 10% (notar que no suman 100%, entonces nos falta algún porcentaje)

Bueno, como sabemos el gráfico (el cual es un círculo) representa el 100%.

Y en un círculo, tenemos un ángulo de 360°

Entonces comenzamos con la equivalencia:

360° = 100%

Entonces, ¿a que grado corresponde el 50%? Planteamos la ecuación:

x = 50%

Si tomamos el cociente entre las ecuaciones:

x = 50% y 360° = 100%

obtenemos:

x/360° = 50%/100%

resolviendo para x, obtenemos:

x = (50%/100%)*360° = 0.5*360° = 180°

Para los otros porcentajes hacemos lo mismo.

Para el de 20% tenemos:

y = 20%

planteamos la ecuación:

y/360° = 20%/100%

y = 0.2*360° = 72°

Finalmente, para el de 10% tendremos:

z = 10%

planteando la ecuación como antes:

z/360° = 10%/100%

z = 0.1*360 = 36°

Asi, hemos encontrado los grados correspondientes para cada porcentaje.

Implicit Differentiation

The derivative of a constant is equal to 0

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Product Rule: $\frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)$

Chain Rule: $\frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)$

Quotient Rule: $\frac{d}{dx} [\frac{f(x)}{g(x)} ]=\frac{g(x)f'(x)-g'(x)f(x)}{g^2(x)}$

Step-by-step explanation:

Step 1: Define

-xy - 2y = -4

Rate of change of the tangent line at point (-1, 4)

Step 2: Differentiate Pt. 1

Find 1st Derivative

Implicit Differentiation [Product Rule/Basic Power Rule]: $-y - xy' - 2y' = 0$
[Algebra] Isolate y' terms: $-xy' - 2y' = y$
[Algebra] Factor y': $y'(-x - 2) = y$
[Algebra] Isolate y': $y' = \frac{y}{-x-2}$
[Algebra] Rewrite: $y' = \frac{-y}{x+2}$

Step 3: Find y

Define equation: $-xy - 2y = -4$
Factor y: $y(-x - 2) = -4$
Isolate y: $y = \frac{-4}{-x-2}$
Simplify: $y = \frac{4}{x+2}$

Step 4: Rewrite 1st Derivative

[Algebra] Substitute in y: $y' = \frac{-\frac{4}{x+2} }{x+2}$
[Algebra] Simplify: $y' = \frac{-4}{(x+2)^2}$

Step 5: Differentiate Pt. 2

Find 2nd Derivative

Differentiate [Quotient Rule/Basic Power Rule]: $y'' = \frac{0(x+2)^2 - 8 \cdot 2(x + 2) \cdot 1}{[(x + 2)^2]^2}$
[Derivative] Simplify: $y'' = \frac{8}{(x+2)^3}$
