Answer:

Step-by-step explanation:

the was I understand matrix multiplication, I re-learned tonight so I could be wrong but.....

according to Gaggle    matrix multiplication is possible when the number of columns in matrix 1  equals the number of rows in matrix 2

       it is called the dot product  (that sounds familiar)

first choice has 2 columns  and 1 row              can't multiple this one

second choice has 1 column  and 2 rows        can't multiple this one

third choice has 2 columns  and 1 row             can't multiple this one

fourth choice has 1 column  and 1 row        This one can be multiplied

Violet looked through a catalog and found a dress. She wanted to order.she used a calculator to determine that the total cost of
aleksklad [387]
So,

Before I do anything, I would like to ask the question that should subconsciously and instantaneously pop into everyone's heads: Why is Violet calculating mills?  Where does she live?  Either it is a place where the value of money is very high, or Violet is very poor, so mills factor into prices.

To round $129.207 to the nearest cent (penny), find the mill's place, which is the 7.

Since 7 is greater than or equal to 5, round up.
$129.207 --> $129.21

Violet's dress will cost $129.21 rounded to the nearest cent.

The Reeds are moving across the country. Mr. Reed leaves 4.5 hours before Mrs. Reed. If he averages 70 mph and she averages 85 m
Bond [772]
I was originally going to graph the two equations, but I don't have graph paper so I set the equations equal to each other.
so Mr.Reeds equation is: y=70x+4.5 and Mrs.Reeds equation is: y=85x
so if I set these equal to each other I would minus the 70x from both sides leaving me with 15x = 4.5. Now since that's done I would divide everything by 15 which will cause me to get a fraction. So once that's done I would be left with x=3/10. I hope this helped!

if theta is in the first quadrant sin left parenthesis t h e t a right parenthesis equals 0.17 then what is tan left parenthesis
Kazeer [188]

The value of tan\theta in the first quadrant is approximately 0.173.

There are 4 quadrants inside the cartesian aircraft. All trigonometric ratios of sin, cos, tan are high quality inside the first quadrant.in the 2nd quadrant simplest sin is advantageous rest are negative.  within the 1/3 quadrant simplest tan is wonderful inside the fourth quadrant best cos is fantastic.

Given sin \theta=0.17 and \theta is in the first quadrant.

We know from trigonometrical identities that

sin^2\theta+cos^2\theta=1

Substituting the value of  sin \theta in the above equation we get:

or, (0.17)^2+cos^2\theta=1\\or,cos^2\theta=1-0.0289\\or.cos\theta=\pm\sqrt{0.9711}\\or,cos\theta=\pm 0.98544...

As \theta lies in the first quadrant then the value of cos\theta is positive.

∴cos\theta\approx0.98544

From the properties of trigonometry we know that :

tan\theta=\frac{sin\theta}{cos\theta}

or,tan\theta=\frac{0.17}{0.98544} \\or,tan\theta=0.17251\\or,tan\theta\approx0.173

The value of tan\theta is approximately 0.173 to the nearest thousandth . The value is positive as the angle lies in the first quadrant.
