Gwen takes out a loan of $400 to pay for an online course. Flat rate interest is charged at 8% p.a
puteri [66]

We know, 1 year = 12 month.

So, 3 month = 3/12 = 0.25 year.

Now, principle amount, P = $400 .

Rate is, r = 8% = 0.08

Time period, t = 0.25 year.

Now, Interest is given by :

I = P × r × t

I = $( 400 × 0.08 × 0.25 )

I = $8

Therefore, she will pay $8 interest in total.

An object moves along a coordinate axis so that its position at time t is given by s(t)=t3. Estimate its instantaneous velocity
Mademuasel [1]

If the position at time <em>t</em> is

<em>s(t)</em> = (1 m/s³) <em>t</em> ³

then the average velocity over <em>t</em> = 2 s and <em>t</em> = 2.001 s is

<em>v</em> (ave) = (<em>s</em> (2.001 s) - <em>s</em> (2 s)) / (2.001 s - 2 s)

<em>v</em> (ave) = ((1 m/s³) (2.001 s)³ - (1 m/s³) (2 s)³) / (2.001 s - 2 s)

<em>v</em> (ave) ≈ (8.01201 m - 8 m) / (0.001 s)

<em>v</em> (ave) ≈ 12.006 m/s

. Part A: Under a dilation of scale factor 3 centered at the origin, AB becomes A'B'. Determine the coordinates of A'B' and sket
Ne4ueva [31]

Answer:

Step-by-step explanation:

Part A.

Coordinates of A and B are,

A(-2, 2) and B(3, 2)

Rule for dilation of a point (x, y) by a scale factor k about the origin,

(x, y) → (kx, ky)

If the points A and B are dilated by a scale factor 3, image points will be,

A(-2, 2) → A'(-6, 6)

B(3, 2) → B'(9, 6)

Part B.

Following the same rule of dilation about the origin by a scale factor of \frac{1}{2} about the origin,

A(-2, 2) → D(-1, 1)

B(3, 2) → C(\frac{3}{2},1)
