Answer:

Option B) $y = (1.31)(2.8^{x})$ is the correct option.

Step-by-step explanation:

<em>Exponential function is the one where, a constant is raised to the power of x, a independent variable.</em>

Here, only option B and D are such exponential functions, while option A is linear and option C is quadratic in nature.

Now, to verify which option is correct, we will input the values and check which has the least difference between the given values.

Or we can use the cost function,

$J = \frac{((y(i))-y)^2}{2m}$ , to find which function has the least error.

By applying the above results,we find Option B is correct.

Which of the following lines are not parallel to the graph of y = 9x + 1

qaws [65]

Answer:

A. 9y - x = 2

Step-by-step explanation:

9y - x = 2. First to get x on the other side we add x to both sides gettings us this. 9y -x + x = 2 + x or just 9y = x + 2. Then divide by 9 to get y alone. We then get y = x/9 + 2/9. The rate of change is clearly not y = 9x here, it's y = x/9 or 1/9x.

Can someone find the area

Juli2301 [7.4K]

Lets split this into two parts; a semi circle and triangle. We can solve fro the area of both individually first.

Area of the Semi Circle:

Formula: A = (πr²)/2

The radius is the diameter divided by two (16 / 2 = 8)

A = (π*8²)/2

A = (π64)/2

A = 200.96/2

A = 100.48 meters

The area of the semi circle is 100.48 meters

Area of the Triangle:

Formula: A = bh/2

A = 16*12/2

A = 192/2

A = 96 meters

The area of the triangle is 96 meters.

To find the total area of the shape, we can add.

100.48 + 96 = 196.48 meters.

Best of Luck!

Commonwealth Company has the following unit costs: direct materials $2, direct labor $4, variable overhead $1, fixed overhead $3

Westkost [7]

Answer: Total unit cost =

variable costs + fixed costs

$2 + $4 + $1 + $3 = $10

Step-by-step explanation:

Total unit cost is calculated by the adding variable costs ( such as the direct material cost per unit, direct labor cost per unit and variable manufacturing overhead per unit,) and fixed costs (such as fixed manufacturing overhead per unit)

Therefore

Total unit cost = variable cost + fixed cost

Unit cost of direct materials = $2

Unit cost of direct labor = $4

Unit cost of variable overhead =$1

Unit cost of fixed overhead = $3

Total unit cost = $2 +$4 + $1 + $3 = $10
