Answer:
(x -4)² +(y +3)³ = 4
Step-by-step explanation:
Each circle is centered on (h, k) = (4, -3). Each circle has a radius 1 unit smaller than the circle just outside of it. The innermost circle shown has a radius of 3, so the next in the pattern of smaller circles will have a radius of 2. The equation for a circle centered at (h, k) with radius r is ...
(x -h)² +(y -k)² = r²
The next circle in the pattern is centered at (4, -3) and has radius 2, so its equation is ...
(x -4)² +(y +3)² = 4
The sum of the angles in a heptagon is 900°, so we would add the real numbers that we have here:
121°+139°+125°+126°+158°+120°=789°
x would equal the remaining value:
x=900-789
x=111°
Answer:
30x6
Step-by-step explanation:
5x6=30
3x2=6
Answer:
Perpendicular means that,second gradient equals to first one as:
So,conducting the second equation to the form y=mx+c: 3y= -2x-5
So it's gradient is
converting to
equals to 1.5 or at least
Y find the equation of the first line you've got to use the formula: y-y1=m (x-x1)
y-1=1.5 (x+6)
y-1=1.5x+9
<u>y</u><u>=</u><u>1</u><u>.</u><u>5x</u><u>+</u><u>10</u><u> </u>is the equation of the first line.
