For the first one:
you change the subtract 2 to add 2 on both sides. so it looks like the picture above. Then you would add 20 + 2 to equal 22. Then you divide that by 1 (from the t). that equals 22, so thats the answer.
Answer:
Step-by-step explanation:
we have a right angle triangle composited in a semi-circle we want to figure out the area of the triangle
in order to do so we need to figure out the adjacent side (height AB)
since the given triangle is a right angle triangle we can consider <u>Pythagoras</u><u> </u><u>theorem </u>given by
given that,a=21 and c=28
substitute:
move left hand side expression to right hand side and change its sign:
square root both sides:
use algebraic indentity:
simplify:
use redical property:
now to figure out the area we can consider the following formula:
remember that,h=AB=7√7 and b=BC=21 thus substitute:
simplify multiplication:
hence,
the area of the triangle is <u>1</u><u>9</u><u>4</u><u> </u> (approximately)
note: you can also use <em>horon's </em>formula but I like to keep things simple
Answer:
The constant <em>a</em> is the scale factor on the parabola; positive <em>a</em> makes a CUP (concave up), which is the usual orientation. Negative <em>a</em> makes an upside-down parabola. Big <em>a</em> (in absolute value) makes a skinny parabola, small <em>a</em> a wider one.
<em>r</em> and <em>s</em> are the zeros of the quadratic function, the values of x that give y=0.
