Answer:

Buenos días;

1) La ecuación de la velocidad en un movimiento uniformemente acelerado (M.U.A) es:

V=V₀+at.

V=30 m/s-2 m/s².t

Ahora elimina las unidades (m/s, m/s₂), y tendrás la ecuación de la velocidad en función del tiempo.  

V(t)=30-2t.

Sol: la ecuación de la velocidad en función del tiempo es : V(t)=30-2t.

2) La ecuación de la posición en función del tiempo en un M.U.A  es:

X=X₀+V₀.t+(1/2).a.t²

X=0+30 m/s.t+(1/2).(-2 m/s²).t²

Eliminas las unidades, y tendrás la ecuación de la posición en función del tiempo.

X(t)=30.t-t².

Sol: la ecuación de la posición en función del tiempo es: X(t):30t-t²

Un saludo.

Find the missing angle in a triangle with the given sides.
aksik [14]

Answer: 72 degree

Step-by-step explanation:

By Angle Sum Property,

53 + 100 + angle C = 180

153 + angle C = 180

angle C = 180 - 153

       =    72 degree

Hope it helped u,

pls mark as the brainliest        - Ayaan707 for help -

Which transformations are needed to change the parent cosine function to<br> y = 0.35cos(8(x-pi/4))
Levart [38]

Here's a list of the changes and their effect:

\begin{array}{c|c|c}\text{From}&\text{To}&\text{Effect}\\\cos(x)&\cos\left(x-\frac{\pi}{4}\right)&\text{Horizontal shift}\\\cos\left(x-\frac{\pi}{4}\right)&\cos\left(8\left(x-\frac{\pi}{4}\right)\right)&\text{Horizontal compression}\\\cos\left(8\left(x-\frac{\pi}{4}\right)\right)&0.35\cos\left(8\left(x-\frac{\pi}{4}\right)\right)&\text{Vertical compression}\end{array}

So, the function is shifted \frac{\pi}{4} units to the right, then it is compressed by a factor 8 horizontally, and a factor 0.35 vertically.

About​ ______% of the area is between z= -1 and z= 1 ​(or within 1 standard deviation of the​ mean)? How do you solve this?
nexus9112 [7]

Answer:

68%

Step-by-step explanation:

<em><u>68-95-99.7% Rule:</u></em>

<em><u /></em>

This is the empirical rule which is used to remember the percentage of values that is within a band of the mean. We say:

  • 68% of the data fall within 1 standard deviation of the mean
  • 95% of the data fall within 2 standard deviation of the mean, and
  • 99.7% of data falls within 3 standard deviations of the mean

Clearly, from the empirical rule, we see that about 68% of the area is between z = -1 and z = 1 (or within 1 standard deviation of the mean)
