Step-by-step explanation:

1) The equation of line is; y = (1/3)x + 1

2) The x - intercept is -3 and the y-intercept is 2

3) Area of CAT is; 6 sq.units

4) Perimeter is; 14.325 units

1) The coordinates of the line AC on the graph are;

A(-3, 0) and C(3, 2)

Thus, equation of line is gotten from the formula;

(y₂ - y₁)/(x₂ - x₁) = (y - y₁)/(x - x₁)

(2 - 0)/(3 + 3) = (y - 0)/(x + 3)

2/6 = y/(x + 3)

3y = x + 3

y = (1/3)x + 1

2) The x - intercept is -3 and the y-intercept is 2

3) Area of CAT is;

Area = 1/2 * base * height

Area = 1/2 * 6 * 2

Area = 6 sq.units

4) Perimeter of ACT is gotten by;

AT + CT + AC

AC = √((2 - 0)² + (3 + 3)²)

AC = √40

Thus;

Perimeter = 2 + 6 + √40

Perimeter = 14.325

If I dilate a number by 1 half, then I will have to dilate it again by 2, to get the same to the same number.

As per the question statement, I dilate a number by 1 half.

We are required to calculate that by what should I dilate the result, to reverb back to the same number that I started with.

To solve this question, first we need to understand the concept of Dilation.

Here, since our first dilation of the original number, say "x" reduces it by 1 half, that is, x becomes (x/2),

To get back to x, we will need to multiply (x/2) by 2 again.

[(x/2) * 2] = x.

Therefore, I will need to enlarge our result with a multiplication with 2 to get back to our original number.

The equation of the line is y = 1/3x - 7

Linear equations are equations that have constant average rates of change.

The given parameters are

Slope, m = 1/3

y-intercept, c = -7

A linear equation is represented as

y = slope * x + y-intercept

i.e.

y = mx + c

Where m =  1/3 and c = -7

So, we have

y = 1/3x - 7

Hence. the linear equation is y = 1/3x - 7

By evaluating h(x) in x = ^-3 and then squaring it, we will see that:

h(-3) = 1,600

Here we have the function:

h(x) = 2x^2 - 5x + 7

First let's evaluate it in x = -3, to do so we just need to replace the variable x by the number 3, we will get:

h(-3) =2*(-3)^2 - 5*-3 + 7

h(-3) = 2*9  + 15 + 7 = 18 + 15 + 7

h(-3) = 40

f(x) = -x² - 4x - 1 is the equation of the parabola in the graph.

From the graph, the parabola passes through point (-1,2) and has a vertex at point (-2,3).

For a parabola with a vertex (h,k), the general equation is expressed as;

y = a( x - h)² + k

First we find 'a', plug in the given coordinates into the equation.

y = a( x - h)² + k

2 = a( -1 - (-2))² + 3

Solve for a

2 = a( -1 + 2 )² + 3

2 = a( 1 )² + 3

2 = a + 3

a = 2 - 3

a = -1

Now substitute the vertex (-2,3 and a ( -1 ) into the general equation.

y = a( x - h)² + k

y = -1( x - (-2))² + 3

Simplify

y = -1( x + 2 )² + 3

Expand using FOIL method

y = -1( (x + 2)(x+2) ) + 3

y = -1( x² + 2x + 2x + 4 ) + 3

y = -1( x² + 4x + 4 ) + 3

Apply distributive property

y = -x² - 4x - 4 + 3

Add like terms

y = -x² - 4x - 1

f(x) = -x² - 4x - 1

Therefore, the equation of the graph is f(x) = -x² - 4x - 1.

The total earnings of the bus driver in a year is $28500.

A function, according to a technical definition, is a relationship between a set of inputs and a set of potential outputs, where each input is connected to precisely one output.

The bus driver works 2000 hours each year and makes $14 per hour.

If the bus driver gets $50 for each new recruit he hired.

Let y be his total earnings and x be the number of new drivers he recruits.

Then his total earnings can be represented by the function:

y = 14 × 2000 + 50 × x

If the bus driver recruits x = 7 new drivers.

y = 28000 + 50 × 7

y = 28000 + 350

y = $28350

If this claim is true then one percent of response times take at least [tex]38.077[/tex] minutes.

In the given question,

A fire department in a rural county reports that its response time to fires is approximately normally distributed with a mean of 22 minutes and a standard deviation of 6.9 minutes.

We have to assuming that the claim is true and finding that one percent of response times take at least how many minutes.

From the question,

Mean [tex]\mu=22[/tex] minutes

Standard deviation [tex]\sigma=6.9[/tex] minutes.

Since the given percentage is [tex]1\%[/tex] and percentage means division of [tex]100[/tex] so we can write [tex]1\%=1/100=0.01[/tex]

So the one percent of response times take at least how many minutes is

[tex]P(x\geq a)=0.01[/tex]

[tex]P(x\geq \frac{a-\mu}{\sigma})=0.01[/tex]

As we know the all values. SO putting the values in the formula

[tex]P(x\geq \frac{a-22}{6.9})=0.01\dots\dots[/tex]Equation 1

From the z table

[tex]P(z\geq 2.33)=0.01\dots\dots[/tex]Equation 2

Now from Equation 1 and Equation 2

[tex]\frac{a-22}{6.9}=2.33[/tex]

Multiply by [tex]6.9[/tex] on both side

[tex]\frac{a-22}{6.9}\times6.9=2.33\times6.9[/tex]

Simplifying

[tex]a-22=2.33\times6.9[/tex]

[tex]a-22=16.077[/tex]

Add [tex]22[/tex] on both side

[tex]a-22+22=16.077+22[/tex]

[tex]a=38.077[/tex]

The events are not independent. Before the first throw, there will be 10 pins to knockdown. Let the number of pins knocked down in the first throw is x.

In the second throw, there will not be 10 pins to knockdown. The number of pins to knockdown in the second throw depends on the number of pins being knocked down in the first throw. Hence, the number of pins to knockdown in the second throw is (10 - x). Thus, the events are dependent

Step-by-step explanation:

10 different bracelets have 3 identical orange beads, 3 identical black beads, and 1 teal bead, if rotating or flipping a bracelet does not change it

Permutations and combinations are the many methods for picking objects from a set to form subsets, usually without replacing them. When the order of selection is a factor, this selection of subsets is known as a permutation; when the order of selection is not a factor, this selection of subsets is known as a combination.

I think it is only 10 ways.

Put the teal bead on first. It is the marker bead. This takes care of the rotation aspect.

Then you have 2 lots of 3 identical beads. so that is 6!/(3!3!) ways to place them. Which is 20 ways.

But the bracelet can be flipped so I think this will halve the number of possibilities

For instance  TOOOBBB is the same as TBBBOOO

So I think the answer is 10 ways.

Slope m is positive when

x₁≥ -2

y₁ ≥ -5

Slope, usually referred to as rise over run, is the "steepness" of the line. By dividing the difference in y values between two points by the difference in x values, we may determine slope. The ratio of the increase in elevation between two points to the run in elevation between those same two points is referred to as the slope. A line that is moving up will have a positive slope, and a line that is moving down will have a negative slope, if you view the line from left to right.

Given,

Point (-2. -5)

Slope = [tex]\frac{y_{1}-(-5) }{x_{1}-(-2) }[/tex]

Slope = [tex]\frac{y_{1}+5 }{x_{1}+2 }[/tex]

y = 4x + 17 is the required equation of line

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Here,

Slope = 4

The line passes through (-3,5)

Equation of line = y - 5 = 4[x - (-3)]

                             y - 5 = 4x + 12

                             y = 4x+ 12 + 5

                             y = 4x + 17
