Find 3 points
(0,-9), (3,-4), (-3,-14)
Plot these points and draw a line through them
Answer:
a is true b is false
Step-by-step explanation:
A explanation
50*400=20000
40*500=20000
B explanation
24*10*90=21600
90*2400=216000
Answer:
Given points
- A = (2, 1)
- B = (4, 3)
- C = (5, 3)
- D = (6, 1)
<h3><u>Part (a)</u></h3>

<h3><u>Part (b)</u></h3>
Trapezoid
<h3><u>Part (c)</u></h3>
To dilate ABCD with a dilation center at (0,0) and a dilation factor of 4, multiply the x and y coordinates of ABCD by sf 4:
- A' = (8, 4)
- B' = (16, 12)
- C' = (20, 12)
- D' = (24, 4)
<h3><u>Part (d)</u></h3>

Well, we can denote L and W for the length and width respectively. Lets say the A is the area, we have: 1. A=(L × W) as well as 2. 2(L+W)=400. We rearrange the second equation to get 3. W=200-L. From this, we can see that 0<L<200. Substitute the third equation into the first to get A=(200L-L²). put this formula into the scientific calculator and you will find a parabola with a maximum. That would be the maximum area of the enclosed area. Alternatively, we can say that L is between 0 and 200 when the area equals 0. (The graph you find will be area against length). As the maximum is generally found halfway, we substitute 100 into the equation and we end up with 10000.
Hope this helps.
