What is f(x) = 0,5 (x-3)( x-5) in general form??​

Mathematics
1 answer:
Citrus2011 [14]3 years ago
4 0

Answer:

f(x)=0.5x^2-4x+7.5

Step-by-step explanation:

The general form of a quadratic function is:

y=ax^2+bx+c

We'll find the general form of the function:

f(x)=0.5(x-3)(x-5)

Multiplying the expressions in parentheses:

f(x)=0.5(x^2-5x-3x+15)

Simplifying:

f(x)=0.5(x^2-8x+15)

Operating:

\mathbf{f(x)=0.5x^2-4x+7.5}

Lee sells electronics. He earns a 5% commission on each sale he makes.
NISA [10]

Answer:

a) c = (5/100)*d

b) c = 0.05*d

c) The ratio between what Lee recieves and what he sold.

d) d = 2000

Step-by-step explanation:

Since Lee earns 5% in commission for each sale then:

a) c = (5/100)*d

b) c = 0.05*d

c) In this context the constant of proportionality means the ratio of the value Lee sold that he'll earn as a comission.

d) Since he wants to earn $100, then c = 100 and we solve for d

c = 0.05*d

100 = 0.05*d

0.05*d = 100

d = 100/0.05 = $2000

He needs to sell $2000.

For questions 2 z 3. simplify each polynomial <br>2. 3x²+6-2x+5x-4x²+9<br>3. 2x²+6x-7x+8-3x²+1​
Mars2501 [29]

Answer:

2. -x^{2} +3x+15

3. -x^{2} -x+9

Step-by-step explanation:

We add like terms together to simplify

2.  3x²-4x²= -x²     -2x+5x= 3x  6+9= 15  all equal to -x²+3x+15

3.  2x²-3x²= -x²      6x-7x= -x    8+1=9      all equal to -x²-x+9

Michael thought he could read 23 pages of his book in class. He was only able to read 20. what is his percent error
Cerrena [4.2K]
Percent error is calculated using

((Actual - predicted) / actual) * 100

In this case, the actual value of the number of pages he read is 20. The expected value was 23. So simply plug in:

((20 - 23) / 20) * 100 = -15%
