Answer:
six and eight ninths
Step-by-step explanation:
Answer:
true
Step-by-step explanation:
1/2 (sin(x+y)+sin(x-y))
= 1/2 (sin x cos Y + cos x sin y + sin x cos y - cos x sin y)
= 1/2 * 2 sin x cos y
= sin x cos y
The expression is true.
Answer:
The correct answer is P = 24 + 8x.
Step-by-step explanation:
First, we must express the length and width of the frame.
Length = 7 + 2x
Width = 5 + 2x
The perimeter is the sum of the four sides of the frame.
P = 2 * (7 + 2x) + 2 * (5 + 2x)
P = 14 + 4x + 10 + 4x
P = 24 + 8x
In this way, we express the perimeter (P) of the frame.
Have a nice day!
Answer:
cos 37=x/b (second one)
sin 37= a/b (third one)
tan 37=a/x (sixth one)
Step-by-step explanation:
Cos is defined by the adjacent side over the hypotenuse. Cos 37 would be x/b. Clearly, that is option 2. Sin is defined by opposite over hypotenuse. Sin 37 would be a/b. That is the 3rd option. Tan is defined by opposite over adjacent. Tan 37 would be a/x or the 6th option.
