If the vertex of a parabola is (-4, 6) and another point on the curve is (-3, 14), what is the coefficient of the squared expres
Luda [366]
\bf \qquad \textit{parabola vertex form}\\\\\begin{array}{llll}
\boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\
x=a(y-{{ k}})^2+{{ h}}
\end{array}\qquad\qquad  vertex\ ({{ h}},{{ k}})\\\\
-------------------------------\\\\
vertex\ (-4,6)\qquad 
\begin{cases}
h=-4\\
k=6
\end{cases}\implies y=a(x-(-4))^2+6
\\\\\\
y=a(x+4)^2+6
\\\\\\
\textit{we also know that }
\begin{cases}
x=-3\\
y=14
\end{cases}\implies 14=a(-3+4)^2+6

A town has a population of 8000 in Groves at 4.5% every year to the nearest year how long will it be until the population will r
VashaNatasha [74]

Answer:

It takes 10 years approximately for the population to reach 22,500

Step-by-step explanation:

Given:

Initial population  =  8000

Population growth rate  4.5 %

Future population = 22500

To Find:

Time taken to reach a population of  22500

Solution:

The population growth can be identified by using

N = N_0e^{(rt)}

where

N is  future popluation

N_0 is the initial population

t is the time taken

r is the rate of the growth

Here we have to find the time t, rephrasing the formula

log(\frac{N}{N_0}) = rt

\frac{log(\frac{N}{N_0})}{r} = t

Substituting the values we get,

t = \frac{log(\frac{22,500}{ 8000})}{ 0.045}

t = \frac{log(2.8125)}{ 0.045}

t = \frac{ 0.449}{ 0.045}

t = 9.97

t=10(approx)

Answer:

Carole's situation :   2x + 11y = 196

Michele's situation:  10x + 11y = 276

Step-by-step explanation:

If x = cost of 1 cupcake, then 2x = cost of 2 cupcakes and 10x = cost of 10 cupcakes, et.

If y = cost of 1 sugar cookie, then 11y = cost of 11 sugar cookies.

Carole's situation :   2x + 11y = 196

Michele's situation:  10x + 11y = 276
