Answer:

Formula: A = 48,000(1+0.02)^t

salary after 30 years: $ 86,945.35

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:  

A = P (1 + r) t  

Where:  

p = initial salary

r = raising rate (decimal form)  

t= years  

A = salary after t years

Replacing with the values given:  

A = 48,000 (1+ 2/100)^t

A = 48,000(1+0.02)^t

Salary after 30 years: substitute t=30

A = 48,000(1+0.02)^30

A = 48,000(1.02)^30

A=$ 86,945.35

Feel free to ask for more if needed or if you did not understand something.

Solve the equation 2x3 + 7x2 – 10x – 24 = 0 in the real number system.
Rom4ik [11]

Answer:

x = 2

x = -4

x = -3/2

Step-by-step explanation:

We need to find the roots of the equation

2x^3 + 7x^2 – 10x – 24 = 0

We can factorize the equation into

(x-2)(x+4)(2x + 3) = 0

Roots

x = 2

x = -4

x = -3/2

Please solve for all three parts of the question.
neonofarm [45]

Answer:

f(-5) = 25

f(0) = -2

f(5) = 16

Step-by-step explanation:

Given the functions;

To get f(-5), we will use the function of x where x is less than 0 since -5 is less than zero

at where x < 0, f(x) = x^2

f(-5) = (-5)^2

f(-5) = 25

b) For f(0), where the point where x = 0, f(x)= -2

Hence the value of f(o) = -2

c) For f(5), the function where x > 5 is f(x) = 2x+6

f(x) = 2x+6

f(5) = 2(5)+6

f(5) = 16
