Jill rides her horse 5 miles due north and 3 miles due east. What is magnitude and direction of her ride

Mkey [24]

First magnitude...

d^2=5^2+3^2

d^2=25+9

d^2=34

d=√34

now for direction...

tanα=y/x

α=arctan(y/x) and we know y=5 and x=3 so

α=arctan(5/3)

α≈59.03624

So the vector of her ride is:

√34, 59.03624° or if you prefer...

√34, 59°2'10" (in standard angle position)

Step-by-step explanation:

ok so try to understand my explaination!

it goes by simplifying one by one :)

(18*2+6x+5)+(3*2-5x-9)

(41+6x)+(-3-5x)

41+6x-3-5x

41-3=38

6x-5x=(1)x

Twelve students took a test and their average score was 85. However, Bob was sick that day. after Bob took the test, the average

Anestetic [448]

Given:

Total number of students, n=12.

The average score of 12 students, a=85.

After Bob took the test, the number of students attended the test, N=13.

The new average score, A=82.

The total score of 12 students is the product of their average score and the number of students.

Hence, the total score of 12 students is,

$\begin{gathered} t=a\times n \\ t=85\times12 \\ t=1020 \end{gathered}$

The total score of 13 students is,

$\begin{gathered} T=A\times N \\ T=82\times13 \\ T=1066 \end{gathered}$

Now, Bob's score can be calculated as,

$\begin{gathered} B=T-t \\ B=1066-1020 \\ B=46 \end{gathered}$

Therefore, Bob's score on the test is 46.
