Kaylee is standing in a stadium and has the option of running up a staircase or down a staircase for exercise. The function f(x)=\frac{1}{50}\big(\left|6x\righ t|+4x\big)f(x)= 50 1 (∣6x∣+4x) will determine how many calories Kaylee will burn if she runs up xx steps. Use a negative value for xx if she runs down the stairs. Find and interpret the given function values and determine an appropriate domain for the function.

40 x 50 = 2000

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4
