A. 2√3
OB. -12i
OC. -2√3
D. 2√31
E. 12/

Answers

Answer 1
Answer:

Final answer:

The expression √√-12 is equivalent to -2√3.


Explanation:

The expression √√-12 represents the square root of the square root of -12. Since the square root of -12 is not a real number, the expression is not defined in the set of real numbers. However, it is possible to define the square root of a negative number using imaginary numbers. The choice equivalent to √√-12 is -2√3 or option C.

The daily demand for ice cream cones at a price of $1.20 per cone is 50 cones. At a price of $2.20 per cone, the demand is 30 cones. Use linear interpolation to estimate the demand at a price of $1.50 per cone.

Answers

The estimated demand for ice cream cones at a price of $1.50 per cone is 44 cones using linear interpolation.

Linear interpolation can be used to estimate the demand at a price of $1.50 per cone based on the given data points.

Let, the price as "P" (in dollars) and the demand as "D" (in cones).

Given data points:

Price = $1.20, Demand = 50 cones

Price = $2.20, Demand = 30 cones

We want to estimate the demand at Price = $1.50.

First, calculate the demand change between the two price points:

Demand change = Demand at $2.20 - Demand at $1.20

Demand change = 30 - 50 = -20 cones

Now, calculate the price difference between the target price ($1.50) and the lower price ($1.20):

Price difference = Target Price - Lower Price

Price difference = 1.50 - 1.20 = 0.30

Next, calculate the proportional change in demand due to the price difference:

Proportional change = (Price difference / Price change) * Demand change

Proportional change = (0.30 / 1.00) * (-20) = -6 cones

Finally, estimate the demand at the target price:

Demand at target price = Demand at lower price + Proportional change

Demand at target price = 50 - 6 = 44 cones

Therefore, the estimated demand for ice cream cones at a price of $1.50 per cone is 44 cones using linear interpolation.

Final answer:

Using linear interpolation, the estimated demand for ice cream cones at a price of $1.50 per cone is 44 cones.

Explanation:

To estimate the demand at a price of $1.50 per cone using linear interpolation:

  1. Calculate the slope or rate of change of the demand by using the formula: slope = (change in demand) / (change in price).
  2. Using the given data, calculate the slope as (30-50) / ($2.20-$1.20) = -20 / $1.00 = -20.
  3. Then, use the slope and one of the given points to find the equation of the linear demand function. Let's use the point (50, $1.20).
  4. The linear demand function is given by: demand = slope * (price - given price) + given demand.
  5. Substituting the values, we have demand = -20 * (price - $1.20) + 50.
  6. Finally, substitute the given price of $1.50 into the demand function: demand = -20 * ($1.50 - $1.20) + 50 = -20 * $0.30 + 50 = 44 cones.

Consider a specific chemical reaction represented by the equation aa + bb → cc + dd. in this equation the letters a, b, c, and d represent chemicals, and the letters a, b, c, and d represent coefficients in the balanced equation. how many possible values are there for the quantity "c/d"?

Answers

We are usually concerned with one reaction. That is, the production of one specific set of products from a specific set of reactants.

The number of values of c/d would be the number of possible ways that a and b could recombine to form different pairs of products c and d. (You might get different reactions at different temperatures, for example. Or, you might get different pars of ions.)

Usually, the number of values of c/d is one (1). (Of course, if you simply swap what you're calling "c" and "d", then you double that number, whatever it is.)

Angel Graham takes out a $150,000 mortgage. This is a 30-year at $725 per month. What is the total amount of interest that Angel will pay on this mortgage?Total Interest = $_____

Answers

Answer:

$111, 000

Step-by-step explanation:

Morgage amount is given as $150, 000

Repayment plan

Every month, Angel pays $725

Therefore, every year, Angel repays $725*12=$8700

The plan goes for 30 years hence

Total amount paid after 30 years will be $8700*30=$261, 000

Interest =Total payment-morgage value

Interest paid=261000-150000=111000

Therefore, total interest is $111, 000
