The area of square ABCD is 7cm².<br> Show that x² + 4x = 3
soldier1979 [14.2K]

Answer:

see explanation

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( s is the measure of a side of the square )

Here s = x + 2 and A = 7, thus

(x + 2)² = 7 ← expand left side using FOIL

x² + 4x + 4 = 7 ( subtract 4 from both sides )

x² + 4x = 3 ← as required

Use the graph to the right to write an equation of the line.
Amanda [17]

Answer:

Using the point (-2,-4) it would be:

y + 4 = 1/3(x + 2)

Using the point (4,-2) it would be:

y + 2 = 1/2 (x - 4)

Step-by-step explanation:

hope this helps :)

This is a question I have been trying to do for quite a while. My additional mathematics exam is next week and I need help. Anyo
Radda [10]

First of all, let's consider the line, since it's simpler to graph: we draw the endpoints and connect them:

f(x)=2-\dfrac{3x}{4\pi} \implies f(0)=2,\quad f(2\pi)=\dfrac{1}{2}

So, you just need to draw the points

(0,2),\quad \left(2\pi, \dfrac{1}{2}\right)

As for the trigonometric function, we have to start from the parent function y=\sin(x) and derive the graph of its child function via transformations:

  • When we multiply the whole function by 2, we stretch the graph vertically. So, the function has still period 2\pi, but now it ranges from -2 to 2 instead of from -1 to 1 (amplitude 2)
  • When we multiply the argument by 2, we compress the function horizontally. So, the new period becomes \pi, and the function makes two complete oscillations from 0 to 2\pi

You can see the two functions in the image below. You can also see that the two graphs cross 4 times, meaning that the equation

y_1=y_2 has four solutions.

Please answer this correctly
Ilya [14]

Answer:

The mode would decrease by 3

Step-by-step explanation:

The mode right now is 6, as there are 4 6's. However, closely behind it is 3, with 3 3's. If we replaced a 6 with a 3, we would have 4 3's and 3 6's. Find the difference between 6 and 3 and you answer should be 3.
