Help with 4 and 5 please!!

Question 4
The magnitude;
Using Pythagoras theorem,
(-200)² + (-530)² = 320900
Length = √320900
= 566.5 mi
To get the angle
Tan θ = opposite/adjacent
= 200/530
= 0.3774
θ = tan^-1 (0.3774)
= 20.67
≈ 21°
The direction from the Cartesian plane is south of west.
Therefore, the magnitude and the direction will be;
About 566.5 mi, 21° south of west

Question 5.
To get the resultant of two vectors we just add the two vectors given.
This involves adding the corresponding values.
Thus, for <-6,5> and <6,-5>
Resultant vector = <(-6+6),(5+-5>
= <0,0>

Sue is reading a book of 360 pages. She read some of the book last week. She plans to read 46 pages today. When she does, she wi

ivanzaharov [21]

Answer: She read 242 pages last week.

Step-by-step explanation:

Total pages = 360

Let the number of pages she read last week = x

( Pages read last week) + (Pages read today) = $\dfrac45$ (Total pages)

i.e. $x+46=\dfrac45(360)$

$\Rightarrow x+46=288\\\\ \Rightarrow x= 288-46\\\\ \Rightarrow x=242$

Hence, she read 242 pages last week.

Discover the area of a circle with a radius of 15 meters ?

Ronch [10]

Answer:

706.5 meters²

Step-by-step explanation:

Area of a circle is: $A=\pi r^2$

'r' is the radius.

We are given the radius of 15 meters.

Using 3.14 for pi:

$A=3.14*15^2\\\rightarrow 15^2=225\\A= 3.14 * 225\\\boxed {A=706.5}$

The area of the circle should be 706.5 meters².
