Answer:

It would be 91 sq. ft.

Step-by-step explanation:

14 x 6 = 84

14 x .5 = 7

84 + 7 = 91 sq. ft.

I hope this helped :D

Ted invests $1077 in a savings account with a fixed annual interest rate of 9% compounded three times per year. What will be the

Juli2301 [7.4K]

Answer: $2,614.16

Step-by-step explanation:

Initially, he has $1077.

We know that this has a fixed annual interest rate of 9% compounded three times per year.

(remember that 9% is 0.09 in decimal form)

Then in one year, this interest is compounded in 3 times.

So we actually apply 0.09/3 3 times.

So if in year zero, Ted has $1077.

after 1 year, Ted will have:

M = $1077*(1 + 0.09/3)^3

Where the power of 3 is because this interest rate is applied 3 times.

Now, after another year Ted will have:

M = $1077*(1 + 0.09/3)^3*(1 + 0.09/3)^3 = $1077*(1 + 0.09/3)^(2*3)

We already can see the pattern here, after N years,

M(N) = $1077*(1 + 0.09/3)^(3*N)

The account balance after 10 years can be computed by evaluating the above equation in N = 10.

M(10) = $1077*(1 + 0.09/3)^(3*10) = $2,614.16

determine the quadratic function of f whose graph is given. The vertex is (1,-3) and the y-intercept is -2

LuckyWell [14K]

Hmmm the y-intercept is at -2? what does that mean? well, is where the graph "intercepts" or touches the y-axis, and when that happens, x = 0, so the point is really ( 0 , -2 ).

and we know where the vertex is at. Let's assume a vertical parabola, in which case the squared variable is the "x".

$\bf \qquad \textit{parabola vertex form}\\\\
\begin{array}{llll}
\boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\
x=a(y-{{ k}})^2+{{ h}}
\end{array} \qquad\qquad vertex\ ({{ h}},{{ k}})\\\\
-------------------------------\\\\
vertex
\begin{cases}
h=1\\
k=-3
\end{cases}\implies y=a(x-1)^2-3
\\\\\\
\textit{now, we also know that }
\begin{cases}
x=0\\
y=-2
\end{cases}\implies -2=a(0-1)^2-3
\\\\\\
1=a(-1)^2\implies \boxed{1=a}\qquad thus\implies 
\begin{cases}
y=1(x-1)^2-3\\
\textit{or just}\\
y=(x-1)^2-3
\end{cases}$

The perimeter of the blueprint is represented by the equation P=8x. What is the equation of the perimeter when solved for x

Korvikt [17]

Answer:

x = P/8

Step-by-step explanation:

The perimeter of the blueprint is given by the equation :

P = 8x

We need to solve the above equation for x.

Dividing both sides of the equation by 8.

$\dfrac{P}{8}=\dfrac{8x}{8}\\\\x=\dfrac{P}{8}$

Hence, the value of x is P/8
