Step 1: find the total exercise number or time which in this situation is 240
step 2: take 240 - 25 minutes of stretching to get 215 and divide it by 5 to get the number per day = 43 minutes a day
step 3: is just recognizing the numbers (5 a day in stretching and 43 a day in running)

final step is the equation use the y intercept of 25 and the variable of running per day to get the equation of (43m + 25 = y

What is the solution to this equation? 2ln4+lnx=3ln2+ln(x+1)

Galina-37 [17]

Answer:

$x=1$

Step-by-step explanation:

Given equation:

$2 \ln 4+\ln x=3 \ln 2+\ln(x+1)$

$\textsf{Apply the power law}: \quad n \ln x = \ln x^n$

$\implies \ln 4^2+\ln x=\ln 2^3+\ln(x+1)$

Simplify:

$\implies \ln 16+\ln x=\ln 8+\ln(x+1)$

Subtract ln 8 from both sides:

$\implies \ln 16+\ln x- \ln 8=\ln(x+1)$

Subtract ln x from both sides:

$\implies \ln 16-\ln 8=\ln(x+1)-\ln x$

$\textsf{Apply the quotient law}: \quad \ln x - \ln y = \ln \frac{x}{y}$

$\implies \ln \left\dfrac{16}{8}\right = \ln \left(\dfrac{x+1}{x}\right)$

Simplify:

$\implies \ln 2 = \ln \left(\dfrac{x+1}{x}\right)$

$\textsf{Apply the equality law}: \quad \textsf{if }\: \ln x= \ln y\:\textsf{ then }\:x=y$

$\implies 2=\dfrac{x+1}{x}$

Multiply both sides by x:

$\implies 2x=x+1$

Subtract x from both sides:

$\implies x=1$

Likurg_2 [28]

Years for one serious accident is 10 year

<u>Given:</u>

Probability of having a serious accident = 10% every year

P(serious accident) = 0.1

Number of years = n

<u>Computation:</u>

Years for one serious accident = 1 / Probability of having a serious accident

Years for one serious accident = 1 / P(serious accident)

Years for one serious accident = 1 / 0.1

Years for one serious accident = 10 year

The function f(x) = 2x + 210 represents the number of calories burned when exercising, where x is the number of hours spent exer

Alex787 [66]

This means 339 calories burned while combining diet with 1 hour of exercise

Step-by-step explanation:

Given the functions as:

f(x)=2x+210

g(x)=2x+125 then

(f+g)(x) = 2x+210 +2x+125 = 4x +335

(f+g)(1) = 4(1)+335

=339

This means 339 calories burned while combining diet with 1 hour of exercise
