What is f(x) = 0,5 (x-3)( x-5) in general form??​
Citrus2011 [14]

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}

If you roll a standard six-sided die, what is the probability that you get a 1, 2, 3, 5, or 6? give your answer as a simplified
Alexxandr [17]

The probability of getting 1, 2, 3, 5, or 6 when you roll a standard six-sided die is 5/6

<h3>How to find the probability of getting a 1, 2, 3, 5, or 6 when you roll a standard six-sided?</h3>

The given parameters are:

Sample space = {1, 2, 3, 4, 5, 6}

So, we have

P(1)  1/6

P(2) = 1/6

P(3) = 1/6

P(5) = 1/6

P(6) = 1/6

The probability of getting 1, 2, 3, 5, or 6 when you roll a standard six-sided die is calculated as:

P = 1/6 + 1/6 + 1/6 + 1/6 + 1/6

So, we have

P =5/6

Hence, the probability of getting 1, 2, 3, 5, or 6 when you roll a standard six-sided die is 5/6

A girl can sweep the garage in 20 minutes, while her brother needs 30 minutes to do the same job. How many minutes will it take
Scrat [10]

I'm not sure your question has enough information to be answered properly, but I'll try to help:

Assuming each of them are sweeping 1/2 of the garge, we're gonna cut each of their times in half.

Now the girl needs 10 minutes for half the garage and her brother needs 15 minutes.

So, if they work together, the first ten minutes will overlap each other while the girls brother gets left behind to finish up for an extra five minutes.

So, when working together, the boy and the girl need 15 minutes to sweep the garage.

MAVERICK [17]

Answer:

y=-x-2

Step-by-step explanation:

To find the slope of the line, you can use the slope formula. I did this with (-3,1) and (2,-4) to get: (1+4)/(-3-2). This ends up as -5/5, which simplifies to -1.

next I plugged in the slope and one point into the line equation: y=mx+b. I plugged in (-4)=(-1)(2)+b. This equated to b=-2.

Check Work:

The equation -4=(-1)(2)-2 is true

The equation 1=(-1)(-3)-2 is true
