Answer:
Step-by-step explanation:
Given
--- candles melted
--- time to melt
Required
The time since the first was lit
If 1 candle melts in 4 hours, 2 candles will melt in 8 hours.
i.e.
For the 3rd candle that has melted, 4 inches
First, calculate the fraction that melt
The time to melt is:
So, the required time is:
Convert to minutes
(x1,y1)
(x2,y2)
(xm,ym)
Midpoint formula is given as below.
((x1 + x2)/2 , (y1 + y2)/2 )
Where
(x1 + x2)/2 = xm ----------- (1)
(y1 + y2)/2 = ym ----------- (2)
Equation (1) implies that;
x1 + x2 = 2xm
x2 = 2xm – x1
Equation (2) implies that;
y1 + y2 = 2ym
y2 = 2ym – y1
Thus the end point is
<span>(x2,y2) = (2xm – x1, 2ym – y1)</span>
To get the awnser u gotta multiply the numbers by pie by one and add them at the end
Answer: -7cos(x)
Step-by-step explanation:
d/dx (f(x))= -7cos(x)
Answer: x<4
Given the inequality:
We want to solve the inequality for x.
First, distribute the bracket on the right side of the inequality.
Next, subtract 10x from both sides of the inequality.
Add 24 to both sides of the inequality.
Divide both sides of the inequality by 6.
The solution to the inequality is x<4.
