Answer: n≥ t + 50

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

<em>During ski season, the owner of a ski shop has determined that the number of customers in a day is greater than or equal to 50 more than the temperature</em>

So, the constant is 50 (Customers)

Variables are:

Number of customers (n)

Temperature (t)

Greater than or equal means ≥.

The inequality is equal to :

n≥ t + 50

Feel free to ask for more if needed or if you did not understand something.

Mary purchases four book online. The book were the same price each, and the shipping fee was $7.25. If the total cost was $55.25
Sonja [21]

Answer:

The price per book that Mary purchased is $12

Step-by-step explanation:

Mary's total cost can be expressed as;

C=(p×n)+s

where;

C=total cost

p=price per unit of books

n=number of books purchased

s=shipping fee

In our case;

C=$55.25

p=unknown

n=4

s=$7.25

replacing;

55.25=(4×p)+7.25

4 p+7.25=55.25

4 p=55.25-7.25

4 p=48

p=48/4

p=12

The price per book that Mary purchased is $12

Determine whether −2 is a zero (root) of the function:
lianna [129]

Answer:

The answer to your question is No

Step-by-step explanation:

Data

function f(x) = 2x³ + x² - 10x - 12

To know if a number is a root of a function, evaluate the function on that number, if the result is zero, then that number is a root.

Substitution          

               f(-2) = 2(-2)³ + (-2)² - 10(-2) - 12

Simplification          

               f(-2) = 2(-8) + 4 + 20 - 12

               f(-2) = -16 + 4 + 20 - 12

               f(-2) = -28 + 24

               f(-2) = -4

-2 is not a root that the function.

The exponential decay graph shows the expected depreciation for a new boat, sell g for $3500, over 10 years.
Alisiya [41]
Okay, the exponential function is
g = a^{x}
The start price of it in t=0 is 3,500, as we can see on the graph. Then, the function becomes
g = 3500^{x}
Let's see at t=2, where the price is g=2000:
2000 =  3500^{x}
Take natural logarithm:
ln 2000 = ln  3500^{x}
x*ln 3500 = ln 2000
x = \frac{ln 2000}{ln 3500} = 0.93
So, the difference between t=0 and t=2 is
x_{t=0}  -  x_{t=2}  = 1 - 0.93 = 0.07
And then we get the change of x in one year equal to 0.035.
So, the final equation is
g =  3500^{1-0.035t}
You can insert any t and see that it is correct, for example t=7
