I don't know what you mean by "area," but what you seem to be talking about is a sector of a circle.
Given the central angle and radius, the area is 2rπ<span>θ.</span>
Answer:
f(x) = x^2 - 7
Step-by-step explanation:
this is because, the y-intercept is (0,-1). If the graph was translated down 6 units, then that means the y-intercept was also shifted 6 units down.
so just subtract 6 from the original y-intercept, -1 -6
hope this helps!
Answer:
rational as it can be in form b/q
Remember you can do anything to an eqautoin as long as you do oit to both sides
-5x=15
try to get 1x by itself
remember
(ax)/a=x when a=a
so
-5x=15
get x
divide both sides by -5
remember to flip sign
(-5x)/(-5)=15/(-5)
x=-3
answer is first one
x=-3
Answer:
14.48 ft
Step-by-step explanation:
The relation between the location of the focus (c), the vertex on the major axis (a) and the vertex on the minor axis (b) with respect the center is:
b² = a² - c²
From the question:
c = 4 ft
a= 30/2 = 15 ft
Replacing into the equation:
b² = 15² - 4²
b = √209
b = 14.48 ft
So, he should build the whisper chamber at 14.48 ft out from the center along the minor axis
