Answer:
72π (I think)
Step-by-step explanation:
Think of it in terms of the entire circle. A semi-circle is just half a circle, so the area of a semicircle will be half of the area of the entire circle. The radius of the semicircle is 6, so the radius of the whole circle is 12. Then, we can do to get the area of the semicircle is 72π. I'm pretty sure that's right. Let me know if I made a mistake somewhere.
Answer:
x^3-x^2+x-2+x^4
Step-by-step explanation:
Remove parenthesis.
3x^3-4x^2+x-7+x^4-2x^3+3x^2+5
Collect like terms.
(3x^3-2x^3)+(-4x^2+3x^2)+x+(-7+5)+x^4
Simplify.
x^3-x^2+x-2+x^4
C Because 15 x pie(3.14)=47.1 and 47.1 x 4= 188.4
Answer:
6.913 cubic-meters/second.
Step-by-step explanation:
Volume of pyramid is.
and
we essentially need to compute derivative at h = 3.
but firs we need to write s in terms of h only, to do that we use the fact that ration of side to height of a pyramid is always constant, which means.
solving for s and substituting in Volume function gives.
and taking derivative with respect to time gives.
but we have been given that piece of information so.
at h = 3 in above we have finally.
F(x) function has a starting value of $6.00 and increases from there.So the y-intercept is 6.
g(x) function shows in the table that when x = 0, y = 6. This is the y-intercept.
h(x) shows on the graph that the y-intercept is 4.
j(x) is an exponential growth function, a * b^x where a is the y-intercept.
y = 10^ x^x has a y-intercept at 10.
The smallest y-intercept is function h(x).
