Let: x = number of copies sold
We can formulate the following equation to solve for x:
1.50x - 0.9x - 600 = 0
x = 1000
Therefore, the club must sell 1000 copies to break even. Among the choices, the correct answer is A.
If 2 1/2 posterboard is enough for 1/2 of the project, it will take another 2 1/2 posterboard to display the other half of the project.
2 1/2 + 2 1/2 = 4 + 1/2 + 1/2 = 4 + 1 = 5
Answer: 5 posterboard.
Answer:
The value of angle B is 33.69°
Step-by-step explanation:
You can find out using Tangent Rule, tanθ = oppo./adj. where opposite and adjacent are the length of triangle :
oppo. = AC = 6 units
adj. = BC = 9 units
θ = ∠B
tan ∠B = AC/BC
tan ∠B = 6/9
∠B = tan^(-1) (6/9)
= 33.69° (near. hundredth)
To answer this, you need to know the general form of an absolute value function. the equation for this is f(x<span>) = </span>a|x<span> - </span>h<span>| + </span>k, and in this equation, the vertex is (h, k).
with that information, you can see that your vertex will be (-5, 7). you must take the negative for 5 because the general equation states that your h value is usually subtracted from x. to check your vertex, try plugging it into your general equation:
f(x) = a|x - (-5)| + 7
f(x) = a|x + 5| + 7 ... you see that this matches your given equation. this last part here was just to show why your 5 must be negative; your answer is bolded.
