<h3>Answer:    y = x+1</h3>

===================================================

Explanation:

f(x) = x^3 - 2x + 3

f ' (x) = 3x^2 - 2 ..... apply the power rule

f ' (1) = 3(1)^2 - 2 ... plug in x coordinate of given point

f ' (1) = 1

If x = 1 is plugged into the derivative function, then we get the output 1. This means the slope of the tangent line at (1,2) is m = 1. It's just a coincidence that the x input value is the same as the slope m value.

Now apply point slope form to find the equation of the tangent line

y - y1 = m(x - x1)

y - 2 = 1(x - 1)

y - 2 = x - 1

y = x - 1 + 2

y = x + 1   is the equation of the tangent line.

The graph is shown below. I used GeoGebra to make the graph.

In a class there are 15 boys and 15 girls 5/6 of the children have brown hair if someone is chosen at random what is the probabi
Cloud [144]

Probability someone chosen at random will not have brown hair = 1/6

<h3>Probability of two variables</h3>

The number of girls = 15

The number of boys = 15

The total number of children = 15 + 15 = 30

Probability that someone chosen at random will have a brown hair, P(Brown hair) = 5/6

P(Brown hair) + P(Not Brown hair) = 1

5/6  +  P(Not brown hair) = 1

P(not brown hair) = 1 - 5/6

P(not brown hair) = 1/6

Therefore, if someone is chosen at random, probability that they will not have brown hair = 1/6

Option 1: y = 5x+5 is the correct answer

Step-by-step explanation:

We can put the values of x in each option one by one and then compare the output to find the best option

So,

<u>For y = 5x+5:</u>

Putting x=1,2,3,4,5...

y = 5(0)+5 = 0+5 = 5\\y = 5(1) +5 = 5+5 = 10\\y = 5(2) + 5 = 10+5 = 15\\y = 5(3) + 5 = 15+5 = 20

The values of x in the function are producing the output values of y, which means that the function for values given in the table is defined by: y= 5x+5

Hence,

Option 1: y = 5x+5 is the correct answer
