What are the solutions to the equation?

Phantasy [73]

Answer:

x = -2 and 1

Step-by-step explanation:

Given :

f(x) = x+2

g(x) = -x²+4

The solution to the equation f(x) = g(x)

=> x+2 = -x²+4

=> x²+x = 4-2

=> x²+x -2 = 0

By factorisation

=> x²+2x-x -2 = 0

=> x(x+2) -1(x+2)

=> (x+2) (x-1)

x = -2 and 1

jeka57 [31]

Step 1: plug in 5 and 2 for your X and Y

Step 2: multiply 8*X or in this case 8*5 and you will get 40

Step 3: multiply 3*Y or in this case 3*2 and you will get 6

Step 4: subtract 40-6 and you will get 34

A disease has a constant force of mortality, µ. Historically 10% of all people with the disease die within 20 years. A more viru

kolbaska11 [484]

Answer:

Step-by-step explanation:

For the disease having force of mortality µ.

we apply exponential distribution law

probability of dying within 20 years

p( x <20) = $1-e^{-\mu}$ = .1

$e^{-\mu}$ = .9

For the disease having force of mortality 2µ.

we apply exponential distribution law

probability of dying within 20 years

p( x <20) = 1 - $e^{-2\mu}$

= 1 - ( .9)²

= 1 - .81

= .19

or 19%
