You’ll get 40 cm because you had to add all of that centimeters are because they all have equal rights

A function f(x)f(x) is graphed on the coordinate plane.

Effectus [21]

Answer

-4x - 2

Explanation

To get the function needed, first calculate the slope of the graph.

slope = (change in y) / (change in x)

= (2 - -2)/(-1 - 0)

= 4/-1

= -4

Now use one of the point (-1, 2) in the graph and a general point (x,y) to find the function.

-4 = (y - 2)/(x - -1)

-4(x + 1) = y - 2

-4x - 4 = y - 2

y = -4x - 4 + 2

= -4x - 2

∴ f(x) = -4x - 2

A particular baseball player has a batting average (number of hits/number of times at bat) of 0.364. What is the probability tha

MAXImum [283]

The correct answer is option (c) P(not a hit) = 0.636

The batting average of the baseball player = $\frac{number of hits}{number of times at bat}$ = 0.364

Now, the probability of occurrence of any event is say, P, the probability of not occurrence of the event is given as = 1 - P

Therefore, the probability that he will not get a hit at his next at bat = 1- 0.364 = 0.636

An isosceles triangle has a perimeter of 18 cm. Find a function that models its area A in terms of the length of its base b.

IgorLugansk [536]

So.... notice the picture below

now, we know what the "height" or "altitude" is
now, we also know the perimeter is 18cm

so, k + k + b = 18
or 2k + b = 18
thus $\bf k=\cfrac{18-b}{2}$

so... one can say that $\bf \textit{area of a triangle}=A=\cfrac{1}{2}bh\qquad 
\begin{cases}
b=b
\\\\
h=\sqrt{k^2-\left( \frac{b}{2} \right)^2}
\\\\
h=\sqrt{k^2-\frac{b^2}{4}}\\
--------------\\
k=\frac{18-b}{2}\qquad thus\\
--------------\\
h=\sqrt{\left( \frac{18-b}{2} \right)^2-\frac{b^2}{4}}
\end{cases}\\\\
-----------------------------\\\\
A=\cfrac{1}{2}\cdot b\cdot \sqrt{\left( \frac{18-b}{2} \right)^2-\frac{b^2}{4}}$

and you can simplify it if you wish.. not sure you have to

Point C has the coordinates (–1, 4) and point D has the coordinates (2, 0). What is the distance between points C and D? units

maw [93]

Answer:

5 units

Step-by-step explanation;

We can use the formula for finding the length or magnitude of line joining two points.

Length = √((x2-x1)² + (y2-y1)²)

The points joining the line are C (-1,4) and D (2,0)

Length = √((2+1)² + (0-4)²)

= √((3²) + (-4)²)

= √ (9+16)

= √25

= 5 units
