Answer:
Hence value for x is 0 degree
Step-by-step explanation:
Given:
x limits are (0 to 360) degrees and
Cos(x+45)+cos(x-45)=Sqrt(2)
To Find:
value for X
Solution:
Given equation cos(x+45)+ cos(x-45)
Is similar to cos(A+B) +cos(A-B)=2cosA*cosB
Now comparing with general formula we get ,
A=x and B=45
S
Hence given equation becomes as ,






x= 0
Hence value for x is 0 degree
She sold 36 White shirts. Its 48 shirts in total so it would be a ratio of 1/4. 1=Blue shirts and 4=total shirts sold. divide 48 by <span>¼.soyou get 12 shirts. the blue shirts of course.48-12 =36. Another way to check your work is 12 x 3 = 36.

Given the table:
x f(x)
2 6
7 3
9 5
To determine the coordinate given in the table, we have the following:
f(2) = 6
f(7) = 3
f(9) = 5
From the answer choices, the only coordinate given is:
f(5) = 9
ANSWER:
f(9) = 5
A = first number (larger number)
b = second number (smaller number)
a = 8b
a - b = 70 *
* since a is the larger number and their difference is positive, we want a-b.
plug the first equation into the second to get :
a - b = 70
(8b) - b = 70
8b - b = 70
Your correct answer would be choice #2.
Answer:
3.5 or 3 1/2
Step-by-step explanation:
1,800-1,450=350
She has 350 calories left to consume 1,800 in total.
There are 3.5 100 calories in 300.
The awnser will be 3.5 or 3 1/2.
She can have 3 1/2 of ice cream.
Hope this helped and you understood :) :)
