Answer:
192 cm^3/min
Step-by-step explanation:
Differentiating the volume expression, we get ...
dV/dt = 2xh(dx/dt) +x^2(dh/dt)
We are given that ...
x = 4 cm, dx/dt = 2 cm/min, h = 15 cm, dh/dt = -3 cm/min
Putting these values into the formula for volume rate of change, we get ...
dV/dt = 2(4 cm)(15 cm)(2 cm/min) +(4 cm)^2(-3 cm/min)
= 240 cm^3/min -48 cm^3/min
dV/dt = 192 cm^3/min
739,000/2,200,000=0.3359
33.5% of the park burned
Answer:
Median, Interquartile range
Step-by-step explanation:
I took the test.
f(5) is 3.
Step-by-step explanation:
- Step 1: Given that f(x) = 3. To find f(5), substitute 5 in place of x.
⇒ f(x) = f(5) = 3
Step-by-step explanation:
This construction bisects the <em>pqr</em> angle.
This is done by placing a compass on the <em>pqr</em> angle and marking construction lines at the points <em>c </em>and <em>a</em>.
Then at where the construction lines at points <em>c </em>and <em>a </em> meet the lines <em>qr </em>and <em>qp </em>draw 2 more from that placement.
Then draw a line running through angle <em>pqr</em> and where the construction lines meet at point <em>b</em>.
Hope this helps and good luck!
