We use the formula V = πr2h to find the volume of a cylinder. Make h the subject of the formula.

Gennadij [26K]

Answer:

V / ( pi r^2) = h

Step-by-step explanation:

V = pi r^2 h

Divide each side by pi r^2

V / ( pi r^2) = pi r^2 h / pi r^2

V / ( pi r^2) = h

a man drives for awhile at 45 mph. Realizing he is late ,he increases his speed to 60 mph and completes his 405 mile trip in 8 h

Harlamova29_29 [7]

By definition, we have the following equation:
d = v * t
Where,
d = Distance
v = rate
t = time

The total distance traveled will be:
45t + 60 (8 - t) = 405
Solving for the time we have:
t = 5 s
Answer:
he drives at 45 mph for 5 s

Which expression gives the y-coordinate of the solution of the system? 3915518_Eqn011.gif

Tems11 [23]

General Idea:

The Cramer's rule can be used to find the value of y.

For a system of equation of the form:

$ax+by+cz=j$

$dx+ey+fz=k$

$gx+hy+iz=l$

Determinant $D =\left[\begin{array}{ccc}a&b&c\\d&e&f\\g&h&i\end{array}\right]$

$D_{y} =\left[\begin{array}{ccc}a&j&c\\d&k&f\\g&l&i\end{array}\right]$

$y=\frac{D_{y}}{D}$

Applying the concept:

$x+2x-2z=3\\3x-y+z=16\\x+z=7$

$D=\left[\begin{array}{ccc}1&2&-2\\3&-1&1\\1&0&1\end{array}\right] \\D=1(-1-0)-2(3-1)-2(0+1)\\D=-1-4-2\\ D=-7$

$D_y=\left[\begin{array}{ccc}1&3&-2\\3&16&1\\1&7&1\end{array}\right] \\ D_y=1(16-7)-3(3-1)-2(21-16)\\ D_y=9-6-10 \\D_y=-7$

Conclusion:

The expression which gives the y-coordinate of the solution of the system is option D.

$OptionD=\frac{\left[\begin{array}{ccc}1&3&-2\\3&16&1\\1&7&1\end{array}\right] }{-7}$
