An equation that is parallel to line y = -3x + 5 and passes through (-4, 5) in point-slope form is y - 5 = -3(x + 4).

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

In Geometry, two (2) lines are parallel under the following conditions:

m₁ = m₂ ⇒ -3 = -3

Note: m represents the slope.

At point (-4, 5), an equation of the line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 5 = -3(x - (-4))

Complete Question:

Write an equation parallel to line y = -3x + 5 and passes through (-4, 5) in point-slope form.

Answer:

91 - 60i

Step-by-step explanation:

(-10 + 3i)² = (-10)² + (2 * -10 * 3i) + (3i)²

= 100 - 60i + 9i²

= 100 - 60i - 9

= 91 - 60i

In the form of a + bi, the answer is 91 - 60i.

The inverse demand function is P = 2400 + 5Q

Given that

Q = 480 - 0.2P

We simply make P the subject of the formula

So, we have

0.2P = 480 - Q

Divide by 0.2

P = 2400 + 5Q

To find the marginal revenue function, we can use the inverse demand function P = 2400 + 5Q, and take the derivative of this function with respect to Q.

The derivative of P with respect to Q is dP/dQ = 5. This represents the change in price for a one unit change in the quantity of operations performed.

So the Marginal Revenue function is MR = dP/dQ * Q = 5Q

To maximize profit, the doctor should equate marginal revenue to marginal cost, which is

MC = dAVC/dQ

So, we have

MC = d(2Q² - 15Q + 400)/dQ

Evaluate

MC = 4Q - 15.

So, we have

5Q = 4Q - 15

Q = -15

Take the absolute value

Q = 15

So, the number of operations is 15

We have

P = 2400 + 5Q

This gives

P = 2400 + 5 * 15

Evaluate

P = 2475

To find the profit, we need to subtract the total cost from the total revenue.

The total revenue is found by multiplying the price by the quantity of operations performed: TR = P * Q = 2475 * 15 = 37125

The total variable cost is found by multiplying the average variable cost by the quantity of operations performed: TVC = AVC * Q = (2Q^2 - 15Q + 400) * Q = 2Q^3 - 15Q^2 + 400Q

The total fixed cost is the fixed cost that doesn't change regardless of the level of output : TFC = $8000

The total cost is the sum of the total variable cost and total fixed cost: TC = TVC + TFC = 2Q^3 - 15Q^2 + 400Q + $8000

The profit is the difference between total revenue and total cost:

π = TR - TC = 37125 - (2Q^3 - 15Q^2 + 400Q + $8000)

When Q = 15,

profit is π = 37125 - (2(15)^3 - 15(15)^2 + 400(15) + $8000)

= 19750

The volume of water which the tank holds when it is full is 136830 cm³.

The amount of space a three-dimensional solid shape takes up is referred to as its volume. Though difficult to visualise in any shape, it can be compared to others. In comparison to an eraser placed inside of it, a compass box has a larger volume. The area of any two-dimensional shape can be calculated by splitting it into equal squares. When calculating the volume of solid shapes, equal cubical units will also be divided.

If the both have diameter of 46 cm then the height of hemisphere is

46/2 = 23 cm = radius

Height of the cylinder = 90 - 23

                                     = 67

Volume of hemisphere + Volume of cylinder =  volume of water

volume of water = (2/3)πr³ + πr²h

volume of water = (2/3)π(23)³ + π(23)²×67

                            = 136830 cm³

a) V = x^3 b) Domain of V = [0, ∞) c) See attached graph d) Maximum = 8 in., V = 512 in^3

a) V = x^3

b) Domain of V = [0, ∞)

c) See attached graph

d) Maximum = x = 8 in., V = x^3 = 512 in^3

The volume V of a cardboard box with a square base is a function of the length x of each edge of the base. To calculate the volume of the box, we can use the formula V = x^3. This means that for any given base length, we can find the volume by cubing the length. The domain of V is the set of all possible values of x, which must be positive. This means that the domain of V is [0, ∞). We can also graph the function V = x^3. The graph looks like a parabola that opens up, with the vertex at the origin. We can then find the maximum of the function, which will be when x = 8 in. At this value, the volume of the box will be V = 512 in^3

This serves as a deterrent to encourage individuals to leave their money in the CD until the maturity date.

Penalty = 2 months of interest = 2 x (Interest rate/100 x Value of CD)

= 2 x (7/100 x 18,000)

= $2520.00

A certificate of deposit (CD) is a financial product offered by banks and credit unions that allows an individual to deposit a certain amount of money for a fixed period of time, usually a few months to a few years. Most CDs will pay a higher rate of interest than a traditional savings account, but they come with certain restrictions. One of these restrictions is that if you withdraw funds from the CD before it reaches maturity, you will be charged a penalty time. This penalty usually involves two months of interest. Therefore, the amount of the penalty for early withdrawal on a CD with a value of $18,000 and paying 7 percent interest would be 2 x (7/100 x 18,000) = $2520.00. This serves as a deterrent to encourage individuals to leave their money in the CD until the maturity date.

Answer: The formula you provided is the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (h) is equal to the sum of the squares of the lengths of the other two sides (a and b). The formula can be written as:

h = √(a^2 + b^2)

To make a the subject of the formula, we can start by squaring both sides of the equation:

h^2 = a^2 + b^2

We can then subtract b^2 from both sides:

h^2 - b^2 = a^2

Now we can take the square root of both sides:

√(h^2 - b^2) = √a^2

a = √(h^2 - b^2)

So, a is the square root of the difference between the square of the hypotenuse and the square of the other side.

x=110

profit =132-110 =22

He made $12 by selling the bicycle helmet to Jin!

Let x be the original cost of the bicycle.

The cost of the helmet is $16, so the original cost of the bicycle and helmet is x + $16 algebraically.

Jin pays a total of $116 + $16 = $132 for the bicycle and helmet, which is 120% of what Stefan spent originally, so x + $16 = 1.2 * (x + $16)

Expanding the right-hand side gives x + $16 = 1.2x + 1.2 * $16.

Solving for x, we find that x = $104.

So, Stefan originally spent $104 for the bicycle and $16 for the helmet, for a total of $104 + $16 = $120.

Stefan sells the bicycle and helmet to Jin for $116 + $16 = $132, so he makes a profit of $132 - $120 = $12.

Answer:

The investments were made as follows:

$10,000 at 7% interest
$13,000 at 6% interest

Step-by-step explanation:

First remember that percentages are to be divided by 100 before any calculations can be made

So 7% = 0.07

8% = 0.08

Let x be the amount invested at 7% and y be the amount invested at 8%

We have:

x + y = 23000    (total amount is $23000)

Return on x = 0.07x

Return on y = 0.06y

Total return is

0.07x + 0.06y = 1480

The two equations are

x + y = 23000    [1]
0.07x + 0.06y = 1480  [2]

To solve for x and y,

multiply [1] x 0.07

=> 0.07x + 0.07y = 0.07(23000)

=> 0.07x + 0.07y =  1610  [3]

Since the coefficients of x are the same we can subtract [2] from [3] to eliminate the x term and solve for y

[3] - [2]:

(0.07x + 0.07y ) - (0.07x + 0.06y) = 1610   - 1480  

0.07x + 0.07y - 0.07x - 0.06y = 130

Collecting like terms

0.07x-0.07x +0.07y - 0.06y = 130

0.01y = 130

y = 130/0.01 = 13000

x = 23000 - 13000 = 10000

Therefore the investments were made as follows:

$10,000 at 7% interest
