1 answer:
Vedmedyk [2.9K]2 years ago
5 0

Step-by-step explanation:

the point of extreme value we get a the zero dilution of the first derivative of the function.

h(t) = -0.2t² + 2t

h'(t) = -0.4t + 2

so,

-0.4t + 2 = 0

2 = 0.4t

t = 2/0.4 = 5 seconds

so, after 5 seconds the ball reaches its maximum height.

FYI : that height is then h(5).

-0.2×5² + 2×5 = -5 + 10 = 5 ft

so, all in all, a very weak kick in very low gravity ...

Step-by-step explanation:

Given

-\frac{3}{x} , \frac{7y}{x}

Required

Add

The statement can be interpreted as:

-\frac{3}{x} + \frac{7y}{x}

Take LCM

-\frac{3}{x} + \frac{7y}{x} = \frac{-3+ 7y}{x}

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

Solve for n: -4(3n+3)=5(-2-6n)-2
STALIN [3.7K]

Answer:

n=0

Step-by-step explanation:

We want to solve for n in the equation

-4(3n+3)=5(-2-6n)-2

We expand using the distributive property to obtain:

-12n-12=-10-30n-2

We group similar terms to get:

-12n+30n=-10+12-2

We simplify to get:

18n=0

Divide through by 18 to get:

n=0
