25^3/2 = (5^2)^3/2 = 5^(2*(3/2)) = 5^3 = 125

Answer:
36 yards of fabric
Step-by-step explanation:
Set up the proportion
quilts/yards = quilts/yards
Let x = no. of yards to make 12 quilts
x/12 = 21/7 = 3
x = 12(3) = 36 yards of fabric
4y=-x-12
y=-1/4x-3
so slope is -1/4 and y intercept is negative three

Answer:
(b) f(x) = 12.5(1.6^x)
Step-by-step explanation:
An exponential model is generally of the form ...
f(x) = a·b^x
where 'a' is the initial value (for x=0), and 'b' is the growth factor, the multiplier when x increases by 1.
<h3>Growth factor</h3>
The ratio of the f(x) values for x=0 and x=1 is 20/12 ≈ 1.67. A number close to this will be the growth factor in the exponential function. There is only one answer choice showing a growth factor near 1.6. (Eliminates choices A, C, D.)
An exponential regression model can be produced by many graphing calculators and spreadsheets. The attachment shows a model that has the values matching choice B.
The answer is c because a subtraction sign means less
