Answer:

This is B) A reflection over the y-axis.

Step-by-step explanation:

You can tell this in a picture due to the fact that each point on the corresponding triangle is equidistant from the y-axis. Take the point at the bottom for instance. In both pictures, it is 2 spaces away from the y axis.

What does the 50th term of this arithmetic sequence: 29,32,35,38

frozen [14]

Answer:

176

Step-by-step explanation:

First term (a) = 29

Common difference (d) = 32 - 29 = 3

For calculating the 50th term , n = 50

Now

$t_{50} = a + ( n - 1) d\\t_{50} = 29 + ( 50 - 1 ) *3\\ t_{50} = 29 + 147\\t_{50} = 176$

hope it will help :)

What is the current density of the solution a/m2

Jlenok [28]

Current density of solution a/m2 is given below

Step-by-step explanation:

Current density is the measure of current generated per unit surface area of electrode.

Eg: In microbial fuel cell/fuel cells, if you are using electrode with size of 5cm x 2cm and current produced is 200mA, then current density will be,

CD= Current/(projected area of electrode)

area of rectangle= LxB= 5cm x 2cm =10cm2

CD= 200mA/10cm2

CD= 20mA/cm2

Your Current will be 200mA.

Current density will be 20mA/cm2.

Below is a map of Yellowstone Park. The scale for the map is 1cm = 25 miles.

eimsori [14]

Answer:

Option D. 75 miles

Step-by-step explanation:

Looking at the Yellowstone Park map we can see that Mrs. Folwer went from Old Faitful to the Canyon by covering a straight line of $3cm$ .

This tells us that we do not need extra calculations to find the distance covered on the map. We also know that the map scale is given as $1cm=25miles$ . So similarly we do not need to do extra ratio conversions.

Thus we know that if $1cm=25miles$ and she covered $3cm$ on the map, we can just multiply covered distance with the equivalency of $cm$ in $miles$ as follow:

$Distance=(3cm) (25 miles)=75miles$

Thus Mrs. Folwer's actual distance from Old Faithful to Canyon in Miles is 75 miles. (<u>which is given in Option D</u>.)
