Hello,

[tex]f(x)=x^3-4x^2-11x+30 \\\\f(0)=30[/tex]

so y-intercept is (0,30)

The product of the roots are -30 = 2 * 5 * -3, and the sum is 4 = 2 + 5 - 3 , so we can factorise

[tex]f(x)=x^3-4x^2-11x+30 \\\\f(x)=0 \\\\<=> x^3-4x^2-11x+30=(x+3)(x-2)(x-5)=0\\\\<=> x=-3 \ or \ x=2 \ or \ x=5[/tex]

x-intercepts are (-3,0) (2,0) and (5,0)

thanks

Using the normal distribution, it is found that:

a) 4.75% of drivers have a reaction time greater than 1.8 seconds.

b) The reaction time is of at least 1.73 seconds.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given by, respectively:

[tex]\mu = 1.5, \sigma = 0.18[/tex]

Item a:

The proportion is one subtracted by the p-value of Z when X = 1.8, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1.8 - 1.5}{0.18}[/tex]

[tex]Z = 1.67[/tex]

[tex]Z = 1.67[/tex] has a p-value of 0.9525.

1 - 0.9525 = 0.0475 = 4.75%.

4.75% of drivers have a reaction time greater than 1.8 seconds.

Item b:

The reaction time is of at least X seconds, in which X is the 90th percentile, that is, X when Z = 1.28, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.28 = \frac{X - 1.5}{0.18}[/tex]

[tex]X - 1.5 = 1.28(0.18)[/tex]

[tex]X = 1.73[/tex]

The reaction time is of at least 1.73 seconds.

The linear equation is given by y = 15x. A person earns $600 for working 40 hours

A linear equation is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept.

The line passes through (7, 105) and (8, 120), hence:

y - 105 = [(120 - 105)/(8-7)}(x - 7)

y = 15x

For 40 hours:

y = 15(40) = $600

if the person got a $50 bonus and also worked some hours, it would change the graph

All you need to do is split the shape so that you can find the individual area

Step-by-step explanation:

So we first split the shape so we get a triangle...

Now we split the shape again to get another square...

Answer:

[tex]g(x) = 5x^2[/tex]

Step-by-step explanation:

In the equation x^2, when x = 1, y = 1. But in g(x), when x is 1, y is 5. Since g(x) is a scaled version of x^2, we can conclude that g(x) is 5 times x^2.

Therefore, [tex]g(x) = 5x^2[/tex].

Answer:

  3 years

Step-by-step explanation:

As with many age problems, you can reason it without equations. If Tom is 13 now, 2 years ago he was 11. If the total age of the two cats at that time was 15, then Tim was 15 -11 = 4.

That means Tim is now 4+2 = 6, so will be 9 in 3 years.

_____

Additional comment

If you want to write equations, there are several ways you can do it. We often like to use variables to represent the current age. We can assign ...

  x = Tim's current age; y = Tom's current age.

The sum of their ages 2 years ago was ...

  (x -2) +(y -2) = 15

Tom's current age is 13, so we have y=13. Using that in the equation gives ...

  x -2 +13 -2 = 15

  x = 6 . . . . . . . . . . subtract 9, collect terms

That's Tim's current age, so Tim will be 9 years old in 3 years.

The area of one wall of the square room is 60 sq. feet.

The area of a square is the square of its side.

If the length of a side of a square is a unit, then its area is

Area = a² sq. units.

In the question, we are informed that a square room has a floor area of 100 sq. feet, and its height is 6 feet.

We are asked to find the area of one wall.

The floor of the room is given a square. We let the length of the side of that square be 'a' units.

Then, its area is a² sq. units.

We are given that the area of the floor is 100 sq. feet.

So, we can write the equation as:

a² = 100 sq. feet,

or, a = 10 feet.

The height of the room is given as 6 feet.

Therefore, the area of a wall is 10*6 sq. feet = 60 sq. feet.

As the floor is rectangular in shape, with dimensions 10 and 6.

Therefore, the area of one wall of the square room is 60 sq. feet.
