Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds. Which piece of information is missing for t
Anit [1.1K]

Answer:

Direction is missing

Step-by-step explanation:

Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds. We know that velocity is a vector quantity. It has both magnitude as well as direction. Velocity is defined as the total distance per unit time I.e.  

                 i.e. the magnitude of velocity is 4.3 m/s  

Here, only velocity is given but its direction is missing. So, the missing information is " the direction ".

X/-4 + 14&gt;20<br><br> someone help a girl out
MrRa [10]

Answer:

x < -20

Step-by-step explanation:

x / -4  + 14 >20

Subtract 14 from each side

x / -4 +14-14 > 20 -14

x / -4 > 6

Multiply each side by -4, remembering to flip the inequality

x / -4 * -4 < 6 * -4

x < -20

Analyzing a Graph In Exercise, analyze and sketch the graph of the function. Lable any relative extrema, points of inflection, a
Anit [1.1K]

Answer:

Analyzed and Sketched.

Step-by-step explanation:

We are given y=\frac{\ln\left(5x)}{x^2}

To sketch the graph we need to find 2 components.

1) First derivative of y with respect to x to determine the interval where function increases and decreases.

2) Second derivative of y with respect to x to determine the interval where function is concave up and concave down.

y'=\frac{1-2\ln\left(5x)}{x^3}=0

x = \sqrt e/5 is absolute maximum

y''=\frac{6\ln\left(5x)-5}{x^4}=0

x=e^{5/6}/5 is the point concavity changes from down to up.

Here, x = 0 is vertical asymptote and y = 0 is horizontal asymptote.

The graph is given in the attachment.
