What is the equation of the following graph in vertex form?

zhuklara [117]

Correct answer is D.

Graph passes through the point (-1, 0).
Therefore, x = -1 and y = 0.

$y=(x+1)^2
\\0=(-1+1)^2
\\0=0^2
\\0=0 \;\; \text{T}$

This is the only equation which is true for x = -1 and y = 0.
Therefore, the solution is $y=(x+1)^2$

determine weather y varies directly with x. if so, find the constant variation and write the equation

REY [17]

Answer:

Yes, k = 1/3 and y = 1/3x

Step-by-step explanation:

$\text{The given line passes through the origin, hence it has equation of the form:}\\y=kx$

$\text{Therefore y varies directly as x.}The line passes through the point (3,1)}$

$\text{This implies that,}$

$1=k(3)\\k=\frac{1}{3}$ $\text{Hence the constant of variation is}$ ⇒ $\frac{1}{3}$

The equation would be ⇒ $y=\frac{1}{3} x$

a company has two packaging machines in a unit, each with a different daily capacity. the capacity of machine 1 is defined by th

Licemer1 [7]

The required function C (m ) which represents the combined capacity of the two machines is $c(m) = 2m^2 + 104m + 1704$

What are functions?

A connection between a collection of inputs and outputs is known as a function.

The given functions are:

$f(m) = (m+40)^2 + 10 \\and\\g(m) = (m+12)^2 - 50$

$C(m) = f(m) + g(m)$

Expanding the two square brackets in the following manner to calculate that sum:

$f(m) = (m+40)^2 + 10 = m^2 + 80m + 1600 + 10 = m^2 + 80m + 1610\\g(m) = (m+12)^2 - 50 = m^2 + 24m + 144 - 50 = m^2 +24m + 94$

$f(m) + g(m) = 2m^2 + 104m + 1704$

Therefore, function C (m ) which represents the combined capacity of the two machines is $c(m) = 2m^2 + 104m + 1704$
