(NR) Natural Resources:Question 10
elena55 [62]

Answer: D) Groundwater collects only where the soil and geological features allow water to seep down into underground chambers.

In other words, as long as there are gaps to allow water through, then that would lead to underground aquifers. Another important component is the amount of rain water that happens. Sources such as rivers, lakes and streams are also a contributing factor.

Stuff like earthquakes, volcanic activity, and continental movement doesn't really have much an effect on where or how aquifers form. It's really all about the soil type and how the landscape is formed, and of course the other factors mentioned in the previous paragraph.

Select all that are undefined. sec (45°) csc (0°) sec (90°)
Murrr4er [49]

Answer:

csc (0°) and sec (90°) are not defined.

Step-by-step explanation:

Given the options wehave to select the option which is undefinesd

First option: sec 45°

sec45^{\circ}=\frac{1}{cos(45^{\circ})}=\frac{1}{\frac{1}{\sqrt2}}=\sqrt2

which is defined

Second option: csc(0°)

csc(0^{\circ})=\frac{1}{sin0}=\frac{1}{0}=\infty

which is not defined

Third option: sec(90°)

sec(90^{\circ})=\frac{1}{cos(90)}=\frac{1}{0}=\infty

which is not defined.

Hence, option 2 and 3 are not defined.

15) A car salesman earns $700 per week plus 2.5% commission on his sales. If he
Snezhnost [94]

Answer:

$2575

Step-by-step explanation:

For this problem, we need to form an equation that represents the car salesman's weekly income.  We are given that he makes at least $700 per week and that he makes 2.5% commission for his sales.  Let n represent the total amount of sales the car salesman made.  So we can build the equation as follows:

f(n) = 0.025n + 700

Note that if we let n = 0 (He made no sales) then he will make his minimum weekly income of $700.

So let's use our formula to calculate how much he made for the week given he made $75000 in sales.

f(75000) = 0.025(75000) + 700

f(75000) = 1875 + 700

f(75000) = 2575

Hence, the car salesman made $2575 for the week.

Cheers.
