Answer:
y=-2x-3
Step-by-step explanation:
Since our equation is in standard form Ax+By=C we must first manipulate the equation so that we have it in the slope-intercept form such that y=mx+b. Therefore:
Therefore, our slope is 1/2 and our y-intercept is 2. Now in order to determine a perpendicular line to the one stated above we must then get the negative inverse of our slope meaning (negative reciprocal). Now we must use the point slope formula:
Where m is the slope, x1 is -2 and y1 is 1 (because of the ordered pair given). And so:
Therefore, the line that is perpendicular to -x+2y=4 is y=-2x-3.
Answer:
h=14.9966
Step-by-step explanation:
1. The formula of the volume is:
V=
2. So you have to substitute the the data that you have:
3533.5=
3. To have the area of the base (ab) you have to get the formula of the circle's area and solve:
A=(
)
A=(
)
A=3.1416(225)
A=706.86in
4. Now you have the area of the base:
3533.5=
5. In this step you are going to clear the variable which is the heigh (h) and solve as an equation:
3533.5=
3533.5(3)=706.86(h)
=h
h=14.9966
The result may vary depending on the value of that you use,
