Averi estaba intentando factorizar 4x^2+20x-164x

Darina [25.2K]

Responder:

El ancho del modelo de área de Averi será x² + 5x-4

Explicación paso a paso:

Deje que el área del modelo de Averi sea igual a la ecuación dada

4x² + 20x-16

Si el mayor factor común del modelo es 4, esto significa que 4 se puede factorizar fácilmente de la ecuación como se muestra;

4 * (x² + 5x-4) ... (1)

Si la fórmula para el modelo de área = Largo * Ancho

Al comparar la fórmula para encontrar el área del modelo con la ecuación 1, el ancho del modelo de área será la función entre paréntesis, es decir,

x² + 5x-4

El ancho del modelo de área de Averi será x² + 5x-4

Lim x-0 (sin2xcsc3xsec2x)/x²cot²4x

sergij07 [2.7K]

By the definitions of cosecant, secant, and cotangent, we have

$\dfrac{\sin2x\csc3x\sec2x}{x^2\cot^24x}=\dfrac{\sin2x\sin^24x}{x^2\sin3x\cos2x\cos^24x}$

Then we rewrite the fraction as

$\dfrac{\sin2x}{2x}\left(\dfrac{\sin4x}{4x}\right)^2\dfrac{3x}{\sin3x}\dfrac{32}{3\cos2x\cos^24x}$

The reason for this is that we want to apply the well-known limit,

$\displaystyle\lim_{x\to0}\frac{\sin ax}{ax}=\lim_{x\to0}\frac{ax}{\sin ax}=1$

for $a\neq0$ . So when we take the limit, we have

$\displaystyle\lim_{x\to0}\cdots=\lim_{x\to0}\frac{\sin2x}{2x}\left(\lim_{x\to0}\frac{\sin4x}{4x}\right)^2\lim_{x\to0}\frac{3x}{\sin3x}\lim_{x\to0}\frac{32}3\cos2x\cos^24x}$

$=1\cdot1^2\cdot1\cdot\dfrac{32}3=\dfrac{32}3$

Throughout the week, Emma reads 1/2 hour on Monday Wednesday and Friday. She also reads 3/4 hour on Tuesday and Thursday. How ma

riadik2000 [5.3K]

Answer:

<u>Emma reads 3 hours each week</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Emma reads 1/2 hour on Monday

Emma reads 3/4 hour on Tuesday

Emma reads 1/2 hour on Wednesday

Emma reads 3/4 hour on Thursday

Emma reads 1/2 hour on Friday

2. How many hours does Emma read each week?

Let's add up all the time Emma reads, this way:

1/2 + 3/4 + 1/2+ 3/4 + 1/2 = 3/2 + 6/4 =

3/2 + 3/2 = 6/2 = 3 hours (Remember 6/4 = 3/2)

<u>Emma reads 3 hours each week</u>

Plz help I’m trying to solve for the indicated variable

Lynna [10]

Hey there! :)

Answer:

a. b = y - mx

b. x = y - b /m

c. t = I/ pr

d. t = A - p/pr

Step-by-step explanation:

a. y = mx + b (for b)

Isolate the b variable by subtracting both sides by mx:

y - mx = b.

Therefore:

b = y - mx.

b. y = mx + b (for x)

Subtract 'b' from both sides:

y - b = mx

Divide 'm' from both sides:

y - b / m = x

c. I = prt

Divide both sides by pr:

I /pr = t.

d. A = p + prt

Subtract p from both sides:

A - p = prt

Divide both sides by pr:

A - p / pr = t

Working together, two people can cut a large lawn in 44 hr. One person can do the job alone in 1 hr less than the other. How lo

garri49 [273]

Turn the word problem to an algebraic one. OK, so two people in forty four hours means 44/2 and the one less than means -1 so if you make each person a variable then guy one is x and guy two is y; therefor it's 44=, man i'm tired the answer is 23.
