Answer:
x = 73.17
Step-by-step explanation:
To solve this problem we are going to have to use trig function
The three main trig functions are
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Hypotenuse
( where hypotenuse = longest length , opposite = side length opposite of angle and adjacent = other side length )
Here, we are given two side lengths and we want to find an angle.
We are given the hypotenuse and its adjacent ( we know this because we are not given its opposite )
When you have the adjacent and hypotenuse you use cosine.
So we have Cos"x" = adj / hyp
adj = 22 and hyp = 76
So Cos"x" = 22/76
==> take the inverse of cos to both sides
x = 73.17 ( rounded to the nearest hundredth )
and we are done!
Answer:
Step-by-step explanation:
1 is x and 0 is y while 6 is x and -3 is y and 6,-3 is the 2nd graph
Answer:
1. $1.5 per pound
2. 8 pounds
3. 3.2 apples
4. 25.6 apples
Step-by-step explanation:
The cost of per pound of apples on sale: 3/2 = 1.5
For $12, the pounds of apples: 12/1.5 = 8
1 lb = 16 oz so 1 apple is 5/16 lb: 1/(5/16) = 3.2
for $12, the number of apples: 8/(5/16) = 25.6
Answer:
4(3x+2)
Step-by-step explanation:
Since all four sides of a square are the same length, the perimeter can be expressed as four times one of the side lengths. In this case, that is 4(3x+2). Hope this helps!
