Which relationships hold true for the sum of the magnitudes of vectors u and v, which are perpendicular?

Answers

it is

B) ||u+v|| = sqrt ||u||2 + ||v||2

AND

D) ||u+v|| less than ||u||+||v||

check the picture below.

notice, the sum of u+v yields the red vector, and its magnitude is smaller than the sum of the other two green ones.

Find the slope Y=5x+12

Answers

Answer: The slope = 5.

Step-by-step explanation:

The equation of a line in the slope -intercept form is given by :-

$y=mx+c$

,where m= slope , c= y-intercept.

The slope of a line represents the rate of change of y with respect to x.

Given: Equation of line : Y= 5x+12

Here Slope (m)=5

Hence, the slope = 5.

Where:

$\diamondsuit~~~\large\boldsymbol{m- > slope}$

$\diamondsuit~~\large\boldsymbol{b- > y-intercept}$

Notes:

Please remember that the slope is the coefficient of x (the number that comes just before x; in 5x, the coefficient of x is 5), and the y-intercept is added to or subtracted from the slope.

Therefore,

Which of the following ratios is equivalent to 12/20? Answers A. 3/10 B. 5:3 c. 120 to 200 D. 60/80

Answers

A is 3/10 , if we multiply top and bottom by 4 we get 12/40 , which is not equivalent to 12/20.

B is 5:3 , it cannot be equivalent to 12/20.

C is 120 to 200 , if we divide both numerator and denominator by 10 we get 12/20, So option C is correct.

D is 60/80 , if we divide both numerator and denominator by 5, we get 12/16 , which is not equivalent to 12/20.

Hence option C is the correct answer.

12 : 20
12 x 10 : 20 x 10
120 : 200 (Answer C)

Mary runs 7 miles in 60 minutes. At the same rate, how many miles would she run in 24 minutes?

Answers

7 miles / 60 minutes = x miles / 24 minutes

cross multiply and simplify to get 2.8 miles.

So, Mary can run 2.8 miles in 24 minutes at the same rate.

If there are 16 ounces in a pound how manyh are in 24 ounces

Answers

16 ounces = 1 pound
1 ounce = 1/16 pound
24 ounces = 1/6 x 24 = 4 pounds

Answer: 4 pounds

Final answer:

24 ounces equals 1.5 pounds, based on the conversion factor of 1 pound equals 16 ounces.

Explanation:

Your question is related to unit conversion. If we know that one pound equals 16 ounces, then to convert 24 ounces to pounds, we must divide 24 ounces by the number of ounces in a pound. Here's how we can do it:

Set up the conversion: 24 oz / 16 oz/lb.
Dividing these amounts gives the result: 24 / 16 = 1.5 lbs.

S, this means that 24 ounces is equal to 1.5 pounds.

You are interested in estimating the the mean age of the citizens living in your community. In order to do this, you plan on constructing a confidence interval; however, you are not sure how many citizens should be included in the sample. If you want your sample estimate to be within 5 years of the actual mean with a confidence level of 94%, how many citizens should be included in your sample? Assume that the standard deviation of the ages of all the citizens in this community is 22 years.
