Answer:

D.) If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.

Step-by-step explanation:

Let us assume x = selling price of each soccer ball

y = daily profit earned from selling of soccer balls

Given that

Y= -6x^2+100x-180

where,

a = -6

b = 100

c = -180

Now we have to applied the formula which is as follows

x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}$

= \frac{-100\pm\sqrt{100^2-4\times -6\times -180}}{2\times -6}$

= \frac{-100\pm\sqrt{10,000 - 4,320}}{-12}$

= \frac{-100\pm\sqrt{5.680}}{-12}$

= \frac{-100 + 75.3658}{-12}$

= \frac{24.6342}{-12}

x^1 = -2.05285

Now

x^2  = \frac{-100 - 75.3658}{-12}$

= \frac{- 175.3658}{-12}

x^2 = 14.6138

Based on this the option D is most appropriate as per the given situation

Talja [164]

Using the distance formula;

|d|=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}

From the points given:

x₁=-1 y₁=-2 x₂=8 y₂=10

substitute the values into the formula;

|d|=\sqrt[]{(8+1)^2+(10+2)^2}=\sqrt[]{9^2+12^2}=\sqrt[]{81+144}

=\sqrt[]{225}=15

The distance is 15 units.

26. The cost of a television set has increased continuously by 2%. In 1999, the average
RUDIKE [14]

Answer:

<u>The exponential model is: Cost after n years = 400 * (1 + 0.02)ⁿ</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Cost of the TV set in 1999 = US$ 400

Annual increase rate = 2% = 0.02

2. Write an exponential model to represent this data.

Cost after n years = Cost in 1999 * (1 + r)ⁿ

where r = 0.02 and n = the number of years since 1999

Replacing with the real values for 2020, we have:

Cost after 21 years = 400 * (1 + 0.02)²¹

Cost after 21 years = 400 * 1.5157

Cost after 21 years = $ 606.28

The TV set costs $ 606.28 in 2020.

<u>The exponential model is: Cost after n years = 400 * (1 + 0.02)ⁿ</u>
