Answer:

  the height when the plant was planted

Step-by-step explanation:

The "y-intercept" is the value of the dependent variable (height) when the independent variable (days) has a value of zero.

The table description tells you the table represents height since the plant was planted. If days since the plant was planted are zero, the height at that time is the height when the plant was planted.

Two identical quarter circles are cut from a rectangle as shown.
Taya2010 [7]
We can see from the diagram that the length of the rectangle is 2 lots of the radius of one quarter circle. The width is made up of one radius, therefore the width is half of the length.

This means that the width of the rectangle is 9cm, and the radius of each quarter circle is 9cm.

To find the shaded area, we find the area of the rectangle and subtract from the areas of each circle, which are equal:

A = lw - 1/2(pi x r^2)
A = 9 x 18 - 1/2(81pi)
A = 162 - 81/2 pi
A = 34.8cm (3sf)

Which of the following is the measure of side a?<br> 23.3<br> 144<br> 8<br> 16
jenyasd209 [6]

Step-by-step explanation:

it is a right-angled triangle, so the side lengths need to fulfill the Pythagoras rule :

c² = a² + b²

where c is the Hypotenuse, the baseline opposite of the 90 degree angle. and a and b (often called legs) are the sides "enclosing" the 90 degree angle.

so, we have

20² = a² + 12²

400 = a² + 144

a² = 256

a = 16

FYI - we could have picked the right answer also by eliminating the wrong given answer options.

as this is a right-angled triangle :

a cannot be longer than the baseline (20).

that eliminates already the first 2 options.

and then look at the picture : a cannot be shorter than b (the other side line (12)).

that eliminates the third option.
