Answer:
18° and 72°
Step-by-step explanation:
Complimentary angles form 90°
We have an angle (x) 4 times larger than the other (y).
Well actually, a system of equations isn't required, so forget about x and y, just divide 90 by 5. This gives you 18, one of the angle's measurements is 18°. Multiply 18 by 4 and get 72. The other angle's measurement is 72°.
Answer:
y = -11x + 9
Step-by-step explanation:
m = -11
x = -1
y = 20
Plug those values into the equation to find b: y = mx + b
20 = (-11)(-1) + b
---> b = 9
Plus m = -11 and b = 9 into y = mx + b
---> y = -11x + 9
Area of square = 24cm²
⇒ Length = √24
Find the diagonal of half the square:
a² + b² = c²
c² = (0.5√24)² + (√24)²
c² = 6 + 24
c² = 30
c = √30
The diagonal of half of the square is the radius of the circle.
⇒ radius = √30
Area of the semicircle = 1/2πr² = 1/2π(√30)² =15π
Answer: 15π²
<em>1. </em>for (0,0) that would be at the very bottom at 0 is where you're point will be.
on (1,4) go over to the right to 1 nd then go up right below 5 and make a point.
for (2,8) go to the right to 2 and then move up to 8 and make a point.
for (3,12) go to the right 3 and then go up to 12 and make a point.
<em>2. </em>It makes a line.
<em>3. </em>(1,5) (2,10) (3,15) (4,20)
chart on left is right but put parenthesis on both side like that ^
<em>4. </em>For Kens go to the right to 1 and go up to 5 and put a point. then go to 2 to the right and 10 up make point. then go 3 to right and 15 up and make a point. then go 4 to right and up 20 and make a point. Do same with other chart.
