Answer:

explanation that will help u get ur answer

Step-by-step explanation:

The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Pie

Answer:

$440 = 2\pi {r}^{2} + 2\pi(r)10 \\$

$3960 = 2\pi {r}^{2} + 2\pi(r)h$

$\frac{3960 = 2\pi {r}^{2} + 2\pi(r)h}{440 = 2\pi {r }^{2} + 2\pi(r)10 }$

$9 = \frac{h}{10}$

2. (6 pts.) Student Engineers Council at a California university has one student representative from each of the five engineerin

yarga [219]

Answer:

(a) There are 20 ways to select both a council president and a vice president.

(b) There are 60 ways to select both a president, a vice president, and a secretary.

(c) There are 10 ways to select two members for the President’s Council.

Step-by-step explanation:

All the five engineering majors have one student representative at the Student Engineers Council at a California university.

(a)

Compute the number of ways to select both a council president and a vice president as follows:

As order of selection is important, the number of ways to select both a council president and a vice president is:

$^{5}P_{2}=\frac{5!}{(5-2)!}=20$

Thus, there are 20 ways to select both a council president and a vice president.

(b)

Compute the number of ways to select president, a vice president, and a secretary as follows:

Again as the order of selection is important, the number of ways to select both a president, a vice president, and a secretary is:

$^{5}P_{3}=\frac{5!}{(5-3)!}=60$

Thus, there are 60 ways to select both a president, a vice president, and a secretary.

(c)

Now for two members for the President's Council are to be selected.

As the order of selection is not important, two members can be selected in:

${5\choose 2}=\frac{5!}{(5-2)!\cdot\ 2!}=\frac{5!}{3!\ \times\ 2!}=10$

Thus, there are 10 ways to select two members for the President’s Council.
