You need the formula for geometric mean for right triangles as it applies to the altitude. For us, that formula will be \frac{BD}{AD}=\frac{CD}{BD} where BD is your altitude. The formula then, filled in accordingly, would be \frac{10}{x}=\frac{4x}{10}. We cross multiply to get that 4x^2=100. Divide both sides by 4 to get x^2=25, so x = 5. Choice C is the one you want.

What is the percent increase modeled in the function f(x)=20(1.5)^x
blagie [28]
The increase is D: 50% because the 1 in the parentheses stands for the 20 that was already there, with the .5 being the amount that’s actually being increased. 0.5 translates to 50%, so the answer is D.

You want to put a fence around your field. The cost of fencing is $60 per meter. The
Darina [25.2K]
Cost per meter(C) = $60/m
Length of rectangular field(L) = 50m
L = 2W
-> W = L/2
-> W = 50/2
-> Width of rectangular field = 25m
Cost of one field length(l) = L x C
-> l = 50 x 60
-> l = $3000
Two of the lengths of the field = 2 x l
-> 2 x $3000
-> $6000

Cost of one field width(w) = W x C
-> w = 25 x 60
-> w = $1500
Two of the widths of the field = 2 x w
-> 2 x $1500
-> $3000

Cost of fencing entire field = $6000+$3000
Hence, total field cost = $9000
