From what I can see, you are on the right track.

one thing you could have done is combine like terms.
{10}^{2}  -  {3}^{2}  =  {7}^{2}

Now just take the square root of 7 squared. That takes out the squared making your answer 7 or G.

You were on the right track, you just skipped a step.

hope this helped!

Parabolic microphones are used for field audio during sports events. The microphones are manufactured such that the equation of
S_A_V [24]

Answer:

a. 8.5 in.

b. 34 in

c. x = 1/39 x^2.

Step-by-step explanation:

Part a.

x = 1/34 y^2

y^2 = 34x

Comparing with y^2 = 4px where p is the focus:

4p = 34

p = 8.5 in.

Part b.

The diameter = 4p = 34 in.

Part c.

Diameter = 4p = 34 + 5 = 39 in

The new equation is x = 1/39 x^2.

What is the total surface area of the drawing?
Soloha48 [4]

Total surface area equals area of 5 rectangular faces + 2 pentagonal faces


Area of 5 rectangular faces

=5 \times 6 \times 9 km^2


=270 km^2


Area of 2 pentagonal faces can be found by drawing 5 isosceles triangles with height as shown in the diagram and multiply the result by 2.


=5 \times \frac{1}{2} \times 9 \times 6.2 \times 2km^2



=279km^2



The toatal surface area is



=270+279=549 km^2


The correct answer is A

Determine Cove’s break-even point in units and sales dollars. 2. Determine the bakery’s margin of safety if it currently sells 4
swat32

Answer:

a) At break even point, Q = 380 units, Sales dollar = $5247.8

b) Margin of safety at Q = 400 units is 0.05 × 100 = 5

c) Number of cakes that need to be sold before a profit of $2200 is made = 595 cakes

Step-by-step explanation:

Let the number of units be Q

Cost equation = (fixed cost) + (Variable cost)

Fixed Cost = $3898.8

Variable Cost = Variable cost per unit × number of units produced = (2.32 + 1.11 + 0.12) × Q = 3.55Q

Cost equation = 3898.8 + 3.55Q

Revenue = price per unit × number of units sold = 13.81 × Q = 13.81Q

At break even point,

Total cost = Revenue

3898.8 + 3.55Q = 13.81Q

10.26Q = 3898.8

Q = 380 units

In sales dollars, R = 13.81Q = 13.81 × 380 = $5247.8

b) Margin of safety = 100 × (Current sales - Breakeven point sales)/(current sales)

Breakeven point sales = $5247.8

At Q = 400 units, Current sales = 13.81 × 400 = $5524

Margin of safety = 100 × (5524 - 5247.8)/5524 = 5

c) number of cakes that Cove must sell to generate $2,200 in profit.

Profit = Revenue - Total Cost

2200 = 13.81Q - (3898.8 + 3.55Q)

2200 = 10.26Q - 3898.8

10.26Q = 2200 + 3898.8 = 6098.8

Q = 594.4 = 595 units
