N=55

A^2 + B^2 = C^2

48^2 + B^2 = 73^2

2304 + B^2 = 5329

-2304 -2304

Answer:

N = 55

Step-by-step explanation:

<h2><u>make use of Pythagoras theorem </u></h2>

which is :

where c is the hypotenuse

a is the adjacent

b is the opposite

c = 73

a = 48

b = N

now plug these in the formula

73^2 = 48^2 + N^2

now make N the subject of formula

73^2 - 48^2 = N^2

3025 = N^2

$\sqrt{3025} \\$ = N

N = 55 --- the murder was not done with a fallen object

Need help with this maybe question

Aleonysh [2.5K]

Answer:

the vertex is:

(2, -1)

Step-by-step explanation:

First solve the equation for the variable y

$x^2-16y-4x-12=0$

Add 16y on both sides of the equation

$16y=x^2-16y+16y-4x-12$

$16y=x^2-4x-12$

Notice that now the equation has the general form of a parabola

$ax^2 +bx +c$

In this case

$a=1\\b=-4\\c=-12$

Add $(\frac{b}{2}) ^ 2$ and subtract $(\frac{b}{2}) ^ 2$ on the right side of the equation

$(\frac{b}{2}) ^ 2=(\frac{-4}{2}) ^ 2$

$(\frac{b}{2}) ^ 2=(-2) ^ 2$

$(\frac{b}{2}) ^ 2=4$

$16y=(x^2-4x+4)-4-12$

Factor the expression that is inside the parentheses

$16y=(x-2)^2-16$

Divide both sides of the equality between 16

$\frac{16}{16}y=\frac{1}{16}(x-2)^2-\frac{16}{16}$

$y=\frac{1}{16}(x-2)^2-1$

For an equation of the form

$y=a(x-h)^2 +k$

the vertex is: (h, k)

In this case

$h=2\\k =-1$

the vertex is:

(2, -1)
