Answer:
y=0.5+sqrt(17)
Step-by-step explanation:
Let y=sqrt{4+sqrt{4+...+sqrt(4)}
y=sqrt(4+y). (Since it's an infinite series)
y^2=4+y, y=0.5-sqrt(17) or 0.5+sqrt(17). We will omit the negative since root values are positive.
Example: What is the area of this rectangle?The formula is:<span>Area = w × h
w = width
h = height</span><span>The width is 5, and the height is 3, so we know w = 5 and h = 3:</span><span>Area = 5 × 3 = 15</span>
Answer:
1. no
2. no
3. no
4. yes
Step-by-step explanation:
Hey there!
d/2 = 2/8
FIRST: you have to CROSS MULTIPLY both of your given numbers
d(8) = 2(2)
d(8) = 8d
2(2) = 4
NEW EQUATION: 8d = 4
SECOND: DIVIDE 8 to BOTH SIDES
8d/8 = 4/8
CANCEL out: 8/8 because that gives you 1
KEEP: 4/8 because it helps you solve for you d-value
NEW EQUATION: d = 4/8
4/8 = d
4/8 = 1/2 = 0.5
Therefore, your answer is: d = 1/2 OR d = 0.5
(NOTE: any of those could work as your “answer” because they are both EQUIVALENT (equal to) to each other)
Good luck on your assignment and enjoy your day!
