Answer:
<h2><em>
85.9° </em></h2>
Step-by-step explanation:
Using the formula for calculating the length of an arc to get the angle of Maple Street to Elm Street;
Length of an arc = θ/360 * 2Πr where r is the radius of the circle.
Given r = 10m and length of the arc = 15m
On substituting;
15 = θ/360 * 2π(10)
15 = θ/360 * 20π
θ/360 = 15/20π
θ/360 = 0.2387
θ = 360* 0.2387
θ = 85.9°
<em>Hence Maple street is at 85.9° to Elm street.</em>

Answer:
D. either x or y must equal 0
Step-by-step explanation:
Its given that xy = 0
Remember that product of two numbers can be zero only if:
Both of them are zero or Either of them is zero as zero multiplied to any non-zero number will always be equal to zero. This is known as Zero Product Property.
So, if the product of x and y is equal to 0 there are two possibilities:
- Both x and y are equal to 0
- Either x or y must be equal to 0
Note that the condition both x and y are equal to zero is not a must condition, because even if one of them is equal to zero, the entire expression will be equal to zero.
Hence, the condition which has to be true in all cases for xy = 0 is:
D. either x or y must equal 0
Answer:
200 packages
Step-by-step explanation:
change 6 m to cm
100 cm = 1 m
6m * 100 cm/1m = 600 cm
we have 600 cm
take 600 cm and divide by 3 cm to close each package
600 cm /3 cm = 200 packages
Given:
To find:
The third term of the sequence.
Solution:
We have,
For n=2, we get
![[\because b(1)=-12]](https://tex.z-dn.net/?f=%5B%5Cbecause%20b%281%29%3D-12%5D)
For n=3, we get
![[\because b(2)=-48]](https://tex.z-dn.net/?f=%5B%5Cbecause%20b%282%29%3D-48%5D)
Therefore, the 3rd term of the sequence is -192.
The answer would be 9,372,300.
