Answer:
x = 65.03°
Step-by-step explanation:
To solve for x, we have to apply trigonometric ratio.
Recall: SOH CAH TOA
From the diagram, we know the following:
Reference angle = x
Hypotenuse = 45
Adjacent = 19
Since we know the Hyp and Adj, we would apply CAH, which is:
Cos x = Adj/Hyp
Plug in the values
x = 65.0250346°
x = 65.03° (nearest hundredth)
Answer:
D. increase of $1 in advertising is associated with an increase of $6,000 in sales.
Step-by-step explanation:
Every dollar in advertisting is multiply by 6 in the equation, but every unit in y represent $1000. That means that $1 1n advertisting is multiply by 6 and then by $1000, that is $1 in advertisting = $6000 in sales.
7.5 is the answer for this questio
Answer:
x = 83/3.
Step-by-step explanation:
12x + 8 + 84 = 15х +9
Solving for x:
8 + 84 - 9 = 15x - 12x
83 = 3x
x = 83/3.
