look at the points that are intersected by the line. the first one is (2,8). put it in as Rise/Run to find the slope. you "rise" 8, and "run" 2

so 8/2 is the slope.

The Pythagorean theorem is a^2+b^2=c^2<br> Solve for b.

rodikova [14]

Answer:

see explanation

Step-by-step explanation:

given

a² + b² = c² ( isolate b² by subtracting a² from both sides )

b² = c² - a² ( take the square root of both sides )

$\sqrt{b^{2} }$ = ± $\sqrt{c^2-a^2}$

b = ± $\sqrt{c^2-a^2}$

Our club has 25 members, and wishes to pick a president, secretary, and treasurer. In how many ways can we choose the officers,

Rus_ich [418]

Answer:

13800

Step-by-step explanation:

The order of the members is important (because each selected member will receive a different position), thus we then need to use the definition of permutation.

There are 25 members, of which 3 are selected.

$\begin{array}{l}n=25 \\r=3\\end{array}$

Evaluate the definition of a combination:

$P(25,3)=\frac{25 !}{(25-3) !}=\frac{25 !}{22 !}=25 \cdot 24 \cdot 23=13800$
