I don't understand this, can somebody please explain it to me?

Artyom0805 [142]

Looking at the equation, you could see that it is in vertex form. Vertex form looks like this: y=a(x-h)^2+k where a is the slope to find the first point away from the origin and (h,k) is the vertex. So, the vertex is (3,-1). The first point away from the origin is up two, over one, so the slope is 2. This means that a is 2. One way you could check this is by putting 2 in for a. If you put it into standard form, it would be 2x^2-12x+17. To find the x in the vertex when the equation is in standard form we use -b/2a. So it would give us 3 for x. If we put in 3 for x, we get -1 for y, so the vertex is (3,-1). This means that a is 2. Sorry for this lengthy answer, hope it helps.

$1,000 is invested at a rate of 3.25%, compounded annually. Identify the compound interest function that models the situation. T

Ulleksa [173]

The compounded interest function that models the situation is: $A=P(1+ \frac{r}{n} )^{nt}$
where
$A$ is the final amount of money after $t$ years.
$P$ is the initial investment.
$r$ is the interest rate in decimal form.
$n$ is the number of times the interest is compounded per year.
$t$ is the time in years.

We know for our problem that $P=1000$ and $t=8$ . To convert the interest rate to decimal form, we are going to divide the rate by 100%:
$r= \frac{3.25}{100}$
$r=0.0325$
We also know that the interest is compounded anally, so it is compounded 1 time per year; therefore, $n=1$ .
Lets replace the values in our formula to find the final amount after 8 years:
$A=P(1+ \frac{r}{n} )^{nt}$
$A=1000(1+ \frac{0.0325}{1} )^{(1)(8)}$
$A=1000(1+ 0.0325 )^{8}$
$A=1291.58$

We can conclude that since we are dealing with compound interest we must use the function $A=P(1+ \frac{r}{n} )^{nt}$ . Also, after 8 years the balance in the account will be $1291.58

Math question: Solve for x 2/3(x - 7) = -2

sasho [114]

2(x-7)/3=-2
3*2(x-7)/2*3=-2*3/2
x-7=-2*3/2
x-7=3*-1
x+(7-7)-7-3
x=7-3
x=4
