Answer:

Figure A

Step-by-step explanation:

We are given that a statement

''If is is an triangle , then it has three vertices.

We have to find that which diagram represents the given statement

From first diagram

If triangle then it have three vertices because intersection of triangle and three vertices is triangle.

From second diagram

Intersection region of three vertices and triangle is three vertices.

So, from second diagram we cannot say if a triangle then it has three vertices.

Hence, figure A represent the given statement.

What is the equation of the line that passes through the point (3, 0) and is perpendicular to the line 2x – y = 5?

Lisa [10]

Answer:

$\large\boxed{y=-\dfrac{1}{2}x+\dfrac{3}{2}}$

Step-by-step explanation:

$\text{Let}\ k:y=_1x+b_1\ \text{and}\ l:y=m_2x+b_2.\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\============================\\\\\text{We have}\ 2x-y=5.\\\\\text{Convert to the slope-intercept form y = mx + b:}\\\\2x-y=5\qquad\text{subtract 2x from both sides}\\\\-y=-2x+5\qquad\text{change the signs}\\\\y=2x-5\to m_1=2\\\\\text{Therefore}\ m_2=-\dfrac{1}{2}.$

$\text{The equation of the searched line:}\ y=-\dfrac{1}{2}x+b.\\\\\text{The line passes through }(3,\ 0).\\\\\text{Put the coordinates of the point to the equation.}\ x=3,\ y=0:\\\\0=-\dfrac{1}{2}(3)+b\\\\0=-\dfrac{3}{2}+b\qquad\text{add}\ \dfrac{3}{2} \text{to both sides}\\\\b=\dfrac{3}{2}$

What is the 101st term for the sequence 13, 9, 5, 1... ?

NeX [460]

Step-by-step explanation:

a=13
d=13-9=4

${:}\longrightarrow$ $\sf S_n={\dfrac {n}{2}}\left [2a-(a-1)d\right]$

${:}\longrightarrow$ $\sf S_101={\dfrac {101}{2}}\left [26 (12)4\right]$

${:}\longrightarrow$ $\sf 50.5×1248$

${:}\longrightarrow$ $\sf S_101=63504$

${:}\longrightarrow$ $\sf a_n=a+(n-1)d$

${:}\longrightarrow$ $\sf a_101=13+(101-1)-4$

${:}\longrightarrow$ $\sf a_101=13+100(-4)$

${:}\longrightarrow$ $\sf 13-400$

${:}\longrightarrow$ $\sf a_101=-387$

Create an example of a situation where there is a negative cash flow.

dimaraw [331]

Answer:

when say your expenses are $400 a month but your income is only $350 a month that is -$50 every month so in that case you aren't getting a positive cash flow (which would be making more money than your expenses) So you must be getting a negative cash flow in which you are losing money and going into debt.

Hope this Helps :)
