Compare the two functions to see which has a greater rate of change. Function 1

AleksAgata [21]

Function 2 has greater rate of change

Step-by-step explanation:

In order to find the rate of change we have to covert the given linear functions in slope-intercept form

Function 1:

$-2x+5y = 10$

Adding 2x on both sides

$-2x+5y+2x = 2x+10\\5y = 2x+10$

Dividing both sides by 5

$\frac{5y}{5} = \frac{2x+10}{5}\\y = \frac{2}{5}x +\frac{10}{5}\\y = \frac{2}{5}x+2$

Let m1 be rate of change of function 1:

$m_1 = \frac{2}{5}$

Function 2:

$-6x+3y = 18$

Adding 6x on both sides

$-6x+3y+6x = 6x+18\\3y = 6x+18$

Dividing both sides by 3

$\frac{3y}{3} = \frac{6x+18}{3}\\y = \frac{6x}{3} + \frac{18}{3}\\y= 2x+6$

Let m2 be the slope of function 2

$m_2 = 2$

As we can see that

$m_2>m_1$

Function 2 has greater rate of change

Heart failures are due to either natural occurrences (87%) or outside factors (13%). Outside factors are related to induced subs

kkurt [141]

Answer:

(a) The probability is 9.49%

(b) The probability is 38.28%

Step-by-step explanation:

The probability that a failure is due to induced substance is calculated as a multiplication as:

(13%) * (73%) = 9.49%

Where 13% is the percentage of heart failures that are due outside factors and 73% is the percentage of outside factors that are due induced substances.

On the other hand, the probability that a failure is due to disease or infection is the sum of the probability that a failure is due to disease and the probability that a failure is due to infection.

Then, the probability that a failure is due to disease is calculated as:

(87%) * (27%) = 23.49%

Where 87% is the percentage of heart failures that are due natural factors and 27% is the percentage of natural factors that are due disease.

At the same way, the probability that a failure is due to infection is calculated as:

(87%) * (17%) = 14.79%

So, the probability that a failure is due to disease or infection is:

23.49% + 14.79% = 38.28%

How do I solve for x?

Ket [755]

Answer:

x=17

Step-by-step explanation:

The Pythagorean theorem

a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse

8^2 + (x-2)^2 = x^2

64 + (x-2)(x-2) = x^2

FOIL

64 + x^2 -2x-2x+4 = x^2

Combine like terms

68+x^2 -4x = x^2

Subtract x^2 from each side

68+x^2-x^2 -4x = x^2-x^2

68 -4x = 0

Add 4x to each side

68-4x+4x= 4x

68 = 4x

Divide by 4

68/4 = 4x/4

17 = x
