Answer:
1%
Step-by-step explanation:
S.P of each radio=$ 2288
Total S.P=$4576
Gain=10%
Lose=10%
C.P=
C.P=
By using the formula
C.P of one radio=$2080
C.P of another radio==$2542.2
Total C.P of two radios=2080+2542.2=$4622.2
Total C.P >Total S.P
Loss=S.P-C.P
Loss=4622.2-4576=$46.2
Loss%=
Loss %=1%
Hence, his loss 1%
Answer:
The value of cos Ф is ±
Step-by-step explanation:
There are important rules for sin Ф and cos Ф
- sin²Ф + cos²Ф = 1
- sin²Ф = 1 - cos²Ф
- cos²Ф = 1 - sin²Ф
∵ sin Ф =
∴ sin²Ф =
∴ sin²Ф =
→ By using the third rule above
∵ cos²Ф = 1 - sin²Ф
∴ cos²Ф = 1 -
∴ cos²Ф =
→ Take square root for both sides
∴ cos Ф = ±
∴ The value of cos Ф is ±
Given:

Find-:
The number shown in standard form and expanded notation
Explanation-:
The standard form is
Standard form = The standard form is
For example, is
The expanded form is
The expanded = Expanded form is a way to write a number by adding the value of its digits. We can use a place value chart to determine the value of a number's digits.
For example
