Which relationships hold true for the sum of the magnitudes of vectors u and v, which are perpendicular? a. ||u+v||=||u||+||v|| b. ||u+v||=sq rt(||u||^2+||v||^2) c. ||u+v||

Answers

Answer 1

Answer:

The perpendicular are B) ||u+v|| = sqrt ||u||^2 + ||v||^2 and D) ||u+v|| less than ||u||+||v||

We have given that,

The relationships hold true for the sum of the magnitudes of vectors u and v,

We have determined which are perpendicular.

What is the magnitude of the vector?

The magnitude of a vector formula is used to calculate the length for a given vector (say v) and is denoted as |v|. So basically, this quantity is the length between the initial point and endpoint of the vector.

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

AND

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

With 28 students randomly picking a stick, what is the probability that the first stick drawn will be green? A. 0.250 B. 0.571 C. 0.036 D. 0.143

Answers

the set of all possible events Ω

Ω = 24 ( 4*7 = 28 stick)

set of events favorable A
A = 7 ( sticks of green is 7)

Probability P
P(A) = A/Ω = 7/28 = 1/4 = 0,25

What is the slope of (1,9) and (6,34)

Answers

Answer:

$m=5$

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDAS

Alg I

Slope Formula: $m=(y_2-y_1)/(x_2-x_1)$

Step-by-step explanation:

Step 1: Define

Point (1, 9)

Point (6, 34)

Step 2: Find slope m

Substitute: $m=(34-9)/(6-1)$
Subtract: $m=(25)/(5)$
Divide: $m=5$

Answer:

The slope is 5

Step-by-step explanation:

so you use formula m= y2-y1/x2-x1 and use 34 as y2, 9 as y1, 6 as x2 and 1 as x1 then plug in numbers when using the formula and do the math and get your slope

In the first 3 days of class, daunte lost 2 pencils. if daunte keeps losing pencils at the same rate for 60 days of class,how many pencils will he lose

Answers

Answer: He would lose 40 pencils in 60 days.

Step-by-step explanation:

Since we have given that

Number of days = 3

Number of lost pencils = 2

If the number of days = 60

Then, the number of lost pencils would be 'x'.

Since there is direct variation between number of days and number of lost pencils.

So, it would be

$(3)/(2)=(60)/(x)\n\n3x=60* 2\n\nx=(120)/(3)\n\nx=40$

Hence, he would lose 40 pencils in 60 days.

He would lose at least 40 pencils.

18 (m + 4/9) - 16 = 118

Answers

18 (m + 4/9) - 16 = 118 Get rid of the parentheses by multiplying 18 * M + 4/9

18M + 8 - 16 = 118 Subtract 8 - 16

18M - 8 = 118 Add 8 to both sides

18M = 118 + 8 Add 118 + 8

18M = 126 Divide 126/18

M = 7

18(m+4/9)-16=118
18m+18*(4/9) -16 = 118 (i used distributive property)
18m+8 -16 = 118
18m-8 = 118
18m = 126 ( i added 8 to both sides)
m = 126/18
m = 7
