Answer:

The correct answer is A. Aimee's graph is correct because the ratio $\frac{2}{3} :1$ is equal to 2:3, which her graph shows in each point.

Step-by-step explanation:

We are given that Aimee noticed her plant grew 2/3 of an inch every week since it sprouted and a graph is drawn to show the plant growth.

We are to determine whether which of the given statements is correct.

The ratio $\frac{2}{3} :1$ is basically equal to 2:3. Therefore, the graph is correct as it shows the same ratio at each point.

For the points (6, 4) and (3, 2) = $\frac{4-2}{6-3} =\frac{2}{3}$

3. March deposited money into an account in which interest is compounded quarterly at a rate of 3.3%. How much did he deposit if

Sergio039 [100]

Answer:

= $ 4344.05

Step-by-step explanation:

Using the formula

A = P (1 +r/n)^nt

Where A is the amount accumulated, P is the principal amount, n is the number of interest periods, t is the time taken in years.

A = $4369.20

r = 0.033

n = 4

t = 21/12

Therefore;

$4369.20 = P ( 1 + 0.033/4)^ (21/12×4)

$4369.20 = P (1.000825)^7

$4369.20 = 1.005789 P

P = $4369.20/1.005789

 = $ 4344.05

For the function y=x^2-4x-5, perform the followingtasks:

Answer:

a. $x^2-4x-5= \left(x-2\right)^2-9$ .

b. The axis of symmetry for ${\left(x - 2\right)^{2}} - 9$ is $x=2$ .

Step-by-step explanation:

a. The vertex form of a quadratic is given by $y=a(x-h)^2+k$ , where (h, k) is the vertex.

To convert from $y=x^2-4x-5$ form to vertex form you use the process of completing the square.

Step 1: Write $x^2-4x-5$ in the form $x^2+2ax+a^2$ . Add and subtract 4:

$x^{2} - 4 x - 5=x^{2} - 4 x + {\left(4\right)} - {4} - 5$

Step 2: Complete the square $x^2+2ax+a^2=\left(x+a\right)^2$

${\left(x^{2} - 4 x + 4\right)} - 9={\left(x - 2\right)^{2}} - 9$

b. The graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola. The x-coordinate of the vertex is the equation of the axis of symmetry of the parabola.

For a quadratic function in standard form, $y=a(x-h)^2+k$ , the axis of symmetry is $x=h$ .
