The formula for the volume of a tetrahedron is given as v=sh. Rewrite the

IrinaK [193]

Answer:

h = 6 units

Step-by-step explanation:

The formula for the volume of a tetrahedron is given as :

V = sh

Where

s is area of base and h is height

Put s = 8 and V = 48 to find h as follows :

$h=\dfrac{V}{s}\\\\=\dfrac{48}{8}\\\\h=6$

So, the height of the tetrahedron is 6 units.

Y=x^2-6x+3 help write the vertex form of the equation

Artist 52 [7]

Answer:

$y=(x-3)^2-6$

Step-by-step explanation:

$y=x^2-6x+3$

This is written in the standard form of a quadratic function:

$y=ax^2+bx+c$

where:

ax² → quadratic term
bx → linear term
c → constant

You need to convert this to vertex form:

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

where:

(h,k) → vertex

To find the vertex form, you need to find the vertex. For this, use the equation for axis of symmetry, since this line passes through the vertex:

$x=-\frac{b}{2a}$

Using your original equation, identify the a, b, and c terms:

$a=1\\\\b=-6\\\\c=3$

Insert the known values into the equation:

$x=-\frac{(-6)}{2(1)}$

Simplify. Two negatives make a positive:

$x=\frac{6}{2} =3$

X is equal to 3 (3,y). Insert the value of x into the standard form equation and solve for y:

$y=3^2-6(3)+3$

Simplify using PEMDAS:

$y=9-18+3\\\\y=-9+3\\\\y=-6$

The value of y is -6 (3,-6). Insert these values into the vertex form:

$(3_{h},-6_{k})\\\\y=a(x-3)^2+(-6)$

Insert the value of a and simplify:

$y=(x-3)^2-6$

Cody's rent is increasing by $51 per month starting next year. That is an increase of 15% from his current monthly rent. Let r r

Inessa05 [86]

Answer:

$r = 43.35$

Step-by-step explanation:

Given

$Current\ Rent = r$

$Increment = 15\%$

$New\ Rent = \$51$

Required

Determine the value of r

The value of r can be set up percentage increase formula as follows:

$\%Increment = \frac{New\ Rent - Current\ Rent}{Current\ Rent}$

Substitute values in the above equation

$15\% = \frac{51 - r}{51}$

Cross Multiply

$51 - r = 15\% * 51$

Convert percentage to decimal

$51 - r = 0.15 * 51$

$51 - r = 7.65$

And the value of $r\ is\ calculated\ using:$

$r = 51 -7.65$

$r = 43.35$

Hence, Cody's current rent is $43.35 monthly
