Leona tracks her calories burned while boxing. The number of calories she burns is expressed by the function c(t) = 425t, where t is the number of hours spent boxing.To burn more calories, Leona wears heavier gloves while boxing. The number of calories she burns while wearing heavier gloves is expressed by the function b(c) = 1.1c, where c is the number of calories burned while boxing without heavy gloves. Which of the following composite functions expresses the calories, as a function of time, Leona burns while boxing with heavy gloves? c[b(t)] = 467.5t c[b(t)] = 426.1t b[c(t)] = 467.5t b[c(t)] = 426.1t

Given the following functions, find g(f(x)). f(x) = 2x + 1 g(x) = x2 + 6

Answers

Answer:

Step-by-step explanation:

g(x) = x^2 + 6

f(x^2 + 6) = 2(x^2 + 6) + 1 = 2x^2 + 12 + 1 = 2x^2 + 13

HELP MATHS perpendicular lines

Answers

Answer:

y = $(1)/(3)$ x + 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given the equation of line L₁

y = - 3x + 8 ← in slope- intercept form

with slope m = - 3

given a line with slope m then the slope of a line perpendicular to it is

$m_(perpendicular)$ = - $(1)/(m)$ = - ( $(1)/(-3)$ ) = $(1)/(3)$ , then

y = $(1)/(3)$ x + c ← is the partial equation of line L₂

to find c , substitute the point P(3, 5 ) into the partial equation

5 = $(1)/(3)$ (3) + c = 1 + c ( subtract 1 from both sides )

4 = c

y = $(1)/(3)$ x + 4 ← equation of line L₂

Elone year, Sales increased by 15%.the following year Sales increased by 1.8% to.
calculate the overall percentage increase in sales

Answers

Answer:

increase 15% = 1+(15/100)=1.15

increase 1.8% =1+(1.8/100)=1.018

evolution coefficient: 1.15*1.018=1.1707

overall percentage increase

(1.1707-1)*100=17.07%
