question 6 - if the area is 144 then one side is 12ft as the square root of 144 is 12
The slope of parallel lines are the same and the slope of perpendicular lines are negative reciprocal
example: parallel, slope line 1: 2 slope line 2: 2
perpendicular, slope line 1: 2 slope line 2: -1/2
You multiply the numbers and add the variable's exponents.
Half one is 1/2;
half three is 3/2;
Thus, if f(x) represents annual growth, f(x)/2 shows it every half-year, like this:
Written in plain text: f(x)=15/2*2^x
Option B: 36 : 1 is the ratio of the surface area of Solid A to Solid B
Explanation:
Given that the Solid A is similar to Solid B.
The volume of Solid A is 3240 m³
The volume of Solid B is 15 m³
We need to find the ratio of the surface area of Solid A to Solid B.
Thus, we have,
Dividing the terms, we get,
Taking cube root, we get,
Squaring the ratios, we get,
Thus, the ratio of the surface area of Solid A to Solid B is 36 : 1
Hence, Option B is the correct answer.
