Answer:
It is scalene and acute.
Step-by-step explanation:
Since it has all acute angles, it is an acute triangle, and since none of the sides are equal or congruent, it is scalene.
The value of f(15), to the nearest hundredth is 253.88
The standard exponential equation is given as:
If f(4.5) = 16, then;
16 = ab^4.5 ..............1
Similarly, if f(9.5) = 60, then:
60 = ab^9.5 ........................... 2
Dividing both equations will give:
60/16 = ab^9.5/ab^4.5
60/16 = b^9.5-4.5
60/16 = b^5
3.75 = b^5
b = 1.3
Get the value of a. Recall that;
60 = ab^9.5
60 = a(1.3)^9.5
60 = 12.09a
a = 60/12.09
a = 4.96
Get the value of f(15)
f()15 = 4.96(1.3)^15
f(15) = 4.96(51.18)
f(15) = 253.88
Hence the value of f(15), to the nearest hundredth is 253.88

Solution:
The ratio of the volumes is 81:1
Explanation:
We have been given that the radii of two similar cones are in the ratio 9:1.
Let a be the radius of first cone and b be the radius of second cone. Then, we have
The volume of the cone is given by
Since, the cones are similar hence, the ratio of volume of these cone is equal to the ratio of the square of the radius.
Thus, the ratio of volume is given by
Therefore, the ratio of the volumes is 81:1
