For the answer to the question above,
<span>the angle of 360 ° → π.d </span>
<span>the angle of x ° → 8π </span>
<span>You make the cross-multiply and you can get: </span>
<span>x * π.d = 8π * 360 </span>
<span>x * d = 8 * 360 </span>
<span>x = 8 * 360/d → where d = 2r </span>
<span>x = 8 * 360/2r </span>
<span>x = 4 * 360/r → where r = 4.5 cm </span>
<span>x = 4 * 360/4.5 </span>
<span>x = 320 °</span>
5/8 is 0.625 , so that would be the decimal for it
Answer:
(-8,-5)
Step-by-step explanation:
Answer:
x = ±3
Step-by-step explanation:
Step 1: Write equation
7x² = 63
Step 2: Solve for <em>x</em>
- Divide both sides by 7: x² = 9
- Square root both sides: x = ±3
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
7(3)² = 63
7(9) = 63
63 = 63
7(-3)² = 63
7(9) = 63
63 = 63
Answer:
y = 3/5x + 4/5 (1st Option)
Step-by-step explanation:
Step 1: Write known variables
m = 3/5
y = 3/5x + b
Step 2: Find <em>b</em>
-1 = 3/5(-3) + b
-1 = -9/5 + b
b = 4/5
Step 3: Rewrite equation
y = 3/5x + 4/5
