using 3.14 for pi
area = pi x r^2
since he can see 12 miles in any direction 12 would be the radius
so 3.14 x 12^2 = 452.16 square miles
round the answer as needed.
Answer:
A) Tan 60° = 1.732
B) H = 12 unit
C) Area of triangle = 41.569 unit²
Step-by-step explanation:
As shown in figure, the triangle with cone angle of 60° and base value 4 unit
A) Now, Tan 60° =
Or, Tan 60° = 1.732
B) To find value of h
since TanФ =
So, Tan 60° =
=
∴() × ( = h
∴ h = 12 unit
C) Area of this triangle = × Perpendicular × Base
= × h ×
∵ Perpendicular h = 12 unit
So, Area = × 12 ×
Hence Area of triangle = 41.569 unit²

1/4(12x-28)
Step-by-step explanation:
1/4(12x-28)=3x-7
Answer:
RPM 1388.889
Horsepower 366.802
Step-by-step explanation:
We do not need to solve the equation for y = 0, which is nice. We can go directly to finding the maximum.
The maximum or minimum of ax^2+bx+c is always at x=-b/2a
with b = 25/45 and a = -1/5000 we get
x = -25/45 / (-2/5000) = 5/9 * 2500 = 12500/9 ≈ 1388.889
Now we only need to put that x into the equation (ideally in form of 12500/9 for accuracy) and we get the horsepower of ~366.802
Answer:
63
Step-by-step explanation:
Each term in a geometric sequence progresses by multiplying a constant (let us name it <u>r</u>).
Let us<u> solve for this constant</u> r in order to find the 13th term.
If the seventh term is 7, the tenth term would be 7*r*r*r, or . We also happen to know that the 10th term is 21. Let us make a <u>new equation</u>:
or, approx. 1.442249570307408
Using the same logic, the 13th term would be 7*r*r*r*r*r*r, or . We may now <u>substitute</u> what we know, r, into this expression to obtain the 13th term:
Therefore, the 13th term of this progression is 63.
