Answer:
Step-by-step explanation:
Given the literal equation, y = 5x - rx - 5,
In order to solve for x, start by adding 5 on both sides of the equation:
y + 5 = 5x - rx - 5 + 5
y + 5 = 5x - rx
Next, factor out x from the right-hand side of the equation:
y + 5 = x(5 - r)
Finally, divide both sides by (5 - r) to isolate x:
Answer:
y = 650·0.922^t
Step-by-step explanation:
At the end of each year, 92.2% of the amount at the beginning of the year remains. That is, the beginning amount is multiplied by 0.922. The exponent t in 0.922^t tells how many times (years) that multiplication has taken place. At the end of t years, the amount remaining in milligrams (y) is ...
y = 650·0.922^t
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
The lateral area of a cylinder is given by:
Area=πrl+2πr^2
radius,r=12 mm
length,l=5*12=60mm
therefore the lateral area will be:
Area=π*12*60
Area=2,261.95 mm^2
The area of the bases will be:
A=2*π*12^2=904.78 mm^s
The lateral area will be:
2,261.95+904.78
=3,166.73
=3167 mm^2
The Answer is B.
Sol: (6/3x^(3-4))^2
= (2/x)^2
=4/x^2
