Answer:

m∠X = 29°

m∠V = 61°

m∠W == 90°⇒given

Step-by-step explanation:

∵ ΔXWV is right angle at W

∴ m∠W = 90°

∴ m∠X + m∠V = 180° - 90° = 90°

∵ m∠X = 2x + 5 and m∠V = 4x +13

∴ 2x + 5 +4x + 13 = 90

∴ 6x + 18 = 90

∴ 6x = 90 - 18 =72

∴ x = 72/6 = 12

∴ m∠X = 2(12) + 5 = 29°

∴ m∠V = 4(12) + 13 = 61°

Find the break - even points for company X, which sells all it produces, if the variable cost per unit is $3, fixed costs are $2
ohaa [14]

Given:

The variable cost per unit is $3, fixed costs are $2.

The revenue function is:

Y_{TR}=5\sqrt{q}

where q is the number of thousands of units of output produced.

To find:

The break - even points for company X.

Solution:

The variable cost per unit is $3, fixed costs are $2.

So, the cost function is:

Total cost = Fixed cost + Variable cost × Quantity

Y_{TC}=2+3q

The revenue function is:

Y_{TR}=5\sqrt{q}

At break - even points the profit is zero. It means the cost and revenue are equal.

Y_{TC}=Y_{TR}

2+3q=5\sqrt{q}

Squaring both sides, we get

(2+3q)^2=(5\sqrt{q})^2

2^2+2(2)(3q)+(3q)^2=25q

4+12q+9q^2-25q=0

4-13q+9q^2=0

Splitting the middle term, we get

4-4q-9q+9q^2=0

4(1-q)-9q(1+q)=0

(4-9q)(1-q)=0

Using zero product property, we get

4-9q=0 and 1-q=0

q=\dfrac{4}{9} and q=1

q\approx 0.444 and q=1

Therefore, the break even points are 0.444 and 1.
