Answer:
a) 
, b) 
, c) 
, d) 
Step-by-step explanation:
a) The perimeter is the sum of the three sides of the internal square and the remaining sides of the external rectangle, that is:
b) The perimeter is the sum of the two sides of the internal triangle and the remaining sides of the external rectangle, that is:
c) The perimeter is the sum of the two sides of the circular section and the three sides of the lower rectangle, that is:
d) The perimeter is the sum of the external sides of the triangle and rectangle, that is:
<span>(4x^3/16x^5)^1/2
= ((4/16) * x^(3-5))^1/2
= ((1/4) * x^-2 ) ^1/2
= 1/ 2x</span>
Answer: 180 degrees
Explanation: I’m assuming PQR is the other half of the circle, 360/2 =180
Answer:
x intercept: x=2.5
y intercept: y=5
slope: -2
formula: y=-2x+5
Step-by-step explanation:
The y intercept is where the line crosses the y axis. You can see that it does so at y=5. The x intercept is where the line crosses the x axis, but it is not immediately apparent where that happens from looking at this graph. However, we can determine that the slope of this line is -2, using the rise/run formula. This means that the formula of this line in y=mx+b form is:
y=-2x+5
Plugging in 0 for y to get the x intercept, you get:
0=-2x+5
2x=5
x=2.5
Thus, the x intercept is at x=2.5.
Answer:
B: A way to draw precise figures using a compass and a straightedge.
Step-by-step explanation:
In geometry, the term 'construction' refers to the draw geometrical shapes and figures accurately. The lines, angles, figures, and shapes are drawn with the help of a compass, ruler, and pencil. Arcs and lines are drawn neatly and angles are constructed. The lines and shapes are constructed without known lengths or angles with the help of the compass, pencil, and ruler.
