A video game sets the points needed to reach the next level based on the function g(x) = 12(2)x − 1, where x is the current leve

Elden [556K]

In the function g(x) the exponent is (x - 1), so g(x) = 12 * 2 ^ (x -1)

h(x) = 3x

So, you have to find the product f(x) * h(x) for x = 6

f(6) = 12 * 2 (6 -1) = 12 * 2(5) = 12 * 32 = 384

h(6) = 3(6) = 18

f(6) * h(6) = 384 * 18 = 6912

Answer: 6912

student's age = x years.

Also ,

Teacher's age = 2x + 6

And ,

Principal's age = 3x + 10

------------------------------------------

Difference between ages ,

$\bold{(3x + 10) - (2x + 6)} \\\bold{ = > 3x + 10 - 2x - 6} \\ \bold{= > x + 4}$

therefore ,

second option is the correct answer.

%of 25 is 14. what percent of 20 is 11? 15 is

ikadub [295]

The first question:

'is' in mathematics means equal
'of' in mathematics means multiplication

$\frac{x}{100} \times 25 = 14\\\\\frac{x}{4} = 14\\\\\boxed{\bf{x=56}}$

56% of 25 is 14.

And the second question:

'is' in mathematics means equal
'of' in mathematics means multiplication

$\frac{x}{100} \times 20 = 11\\\\\frac{x}{5} = 11\\\\\boxed{\bf{x = 55}}$

55% of 20 is 11.
