⇒Number of Months since Opening----Y axis

Answer:

8 + i

Step-by-step explanation:

What you need to simplify this is the following "definitions" of i to different powers.

[tex]i^1=i[/tex]

[tex]i^2=-1[/tex]

[tex]i^3=i^2*i=-1*i=-i[/tex]

[tex]i^4=1[/tex]

Now we can sub these in for the various powers of i in our expression:

[tex]6(1)+6(-i)-2(-1)+\sqrt{-1*49}[/tex]

Simplifying a bit:

[tex]6-6i+2+\sqrt{i^2*49}[/tex]

Since we know that the square root of i-squared is i, and that the square root of 49 is 7, we can get rid of the radial sign as follows:

6 - 6i + 2 + 7i

And the final answer, in a + bi form, is

8 + i

Answer:

y < 2/3 x - 1 is the linear inequality which represented by the graph ⇒ 4th answer

Step-by-step explanation:

* Lets explain how to solve the problem

- At first lets find the equation of the line

∵ The line passes through points (3 , 1) and (-3 , -3)

∵ The form of the equation is y = mx + c, where m is the slope of the

  line and c is the y-intercept

- The rule of the slope of any line passes through points (x1 , y1) and

  (x2 , y2) is m = (y2 - y1)/(x2 - x1)

- The y-intercept means the intersection between the line and the

  y-axis at point (0 , c)

∵ (3 , 1) and (-3 , -3) are two points on the line

- Let (x1 , y1) is (3 , 1) and (x2 , y2) is (-3 , -3)

∴ The slope of the line m = (-3 - 1)/(-3 - 3) = -4/-6 = 2/3

∵ The line intersects the y-axis at point (0 , -1)

∴ c = -1

∵ The equation of the line is y = mx + c

∴ The equation of the line is y = 2/3 x + -1

∴ The equation of the line is y = 2/3 x - 1

- If the shaded part is over the line then the sign of inequality is ≥ or >

- If the shaded part is under the line then the sign of inequality is ≤ or <

- If the line represented by solid line (not dashed), then the sign of

 inequality is ≥ or ≤

- If the line represented by dashed line (not solid), then the sign of

 inequality is > or <

∵ The shading part is under the line

∵ The line is dashed

∴ The sign of the inequality is <

∴ y < 2/3 x - 1

* y < 2/3 x - 1 is the linear inequality which represented by the graph

The linear inequality represented by the graph is y < (2/3) * x - 1

To solve the problem, we can follow these steps:

Find the equation of the line that passes through the points (3, 1) and (-3, -3). The equation of a line is in the form y = mx + c, where "m" is the slope and "c" is the y-intercept.

Use the slope formula to calculate the slope (m) of the line. The slope formula is given by m = (y2 - y1) / (x2 - x1), where (x1, y1) is (3, 1) and (x2, y2) is (-3, -3).

Calculate the slope (m):

m = (-3 - 1) / (-3 - 3) = -4 / -6 = 2/3

Determine the y-intercept (c), which is the point where the line intersects the y-axis. In this case, it's at point (0, c).

Since the line passes through (3, 1), we can use this point to find the y-intercept:

1 = (2/3) * 3 + c

1 = 2 + c

c = -1

Now that we have the slope (m) and the y-intercept (c), we can write the equation of the line:

y = (2/3) * x - 1

Determine the direction of the shading in the inequality. If the shaded region is under the line, the sign of the inequality is "<."

Determine the style of the line on the graph. If the line is dashed, the sign of the inequality is also "<."

Combine the information to form the linear inequality:

y < (2/3) * x - 1

So, the linear inequality represented by the graph is:

y < (2/3) * x - 1

Answer:

612 times does the clock chime

Step-by-step explanation:

Given data

two times 15 minutes after the hour

four times 30 minutes after the hour

six times 45 minutes after the hour

clock chimes 8 + 2 = 10 times

to find out

how many times does the clock chime in a 24-hour period

solution

we can say clock chimes from 12:05 - 1:05  is for this 1 hour

2 +4+6+8 = 20 + 1

and clock chimes from 1:05 - 2:05  is for this 1 hour is 20 +2

and we know for 24 hours clock chimes  is 20 × 24 i.e

= 480 + 2 × ( 1 +2 + ...  +11 )     .....................1

we know

2 × ( 1 +2 + ...  +11 ) will be  = 2 × (n) × (n+1) / 2

here n is 11 so

= 2 × (n) × (n+1) / 2

= 2 × (11) × (11+1) / 2

= 132

so now put this in equation 1

we get

clock chime in a 24-hour period = 480 + 132

clock chime in a 24-hour period = 612

so 612 times does the clock chime in a 24-hour period

I'm going to write both of this as improper fractions.

That is the mixed fraction [tex]a\frac{b}{c}[/tex] can be written as the improper equivalent fraction of [tex]\frac{ca+b}{c}[/tex] assuming [tex]a[/tex] is positive.

So we are going to write [tex]-3\frac{1}{3}[/tex] as [tex]-\frac{3(3)+1}{3}[/tex].

Simplifying that gives us [tex]-\frac{10}{3}[/tex].

Now for [tex]-8\frac{7}{10}=-\frac{10(8)+7}{10}=-\fraC{87}{10}[/tex].

Now we are ready to find the product which just means multiply:

[tex]\frac{-10}{3} \cdot \frac{-87}{10}[/tex]

To multiply fractions you just multiply straight across on top and straight across on bottom unless you see a common factor on and bottom to cancel (and I do; I see 10)

[tex]\frac{-1}{3} \cdot \frac{-87}{1}[/tex]

[tex]\frac{87}{3}[/tex]

Negative times negative is positive.

Answer:

b. 19.54 ft²

Step-by-step explanation:

Measure of the central angle made by the arc CD = 35 degrees

Measure of radius of circle = r = 8 feet

Area of the sector is calculated as:

[tex]A=\frac{1}{2}r^{2} \theta[/tex]

Where the angle [tex]\theta[/tex] is in radians.

35 degrees in radian would be = [tex]35 \times \frac{\pi}{180} = \frac{7 \pi}{36}[/tex]

Using the values in the formula, we get:

[tex]Area = \frac{1}{2} \times (8)^{2} \times (\frac{7 \pi}{36} )\\\\ Area = 19.54[/tex]

Thus, the area of the sector bounded by arc CD would be 19.54 ft²

Step-by-step explanation:

Therefore, the zeroes of the function [tex]\( f(x) = x^2 - x - 2 \)[/tex] are [tex]\( x = 2 \)[/tex] and [tex]\( x = -1 \).[/tex]

To find the zeroes of the quadratic function [tex]\( f(x) = x^2 - x - 2 \),[/tex] we need to solve for [tex]\( x \)[/tex] when [tex]\( f(x) = 0 \)[/tex]. This means we need to find the values of [tex]\( x \)[/tex]that make the function equal to zero.

We can solve this quadratic equation by factoring or using the quadratic formula. Let's use the quadratic formula:

For a quadratic equation in the form [tex]\( ax^2 + bx + c = 0 \)[/tex], the solutions [tex]\( x \)[/tex] are given by:

[tex]\[ x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}} \][/tex]

For our equation [tex]\( f(x) = x^2 - x - 2 \)[/tex], we have [tex]\( a = 1 \), \( b = -1 \)[/tex], and [tex]\( c = -2 \)[/tex]. Substituting these values into the quadratic formula:

[tex]\[ x = \frac{{-(-1) \pm \sqrt{{(-1)^2 - 4(1)(-2)}}}}{{2(1)}} \][/tex]

[tex]\[ x = \frac{{1 \pm \sqrt{{1 + 8}}}}{2} \][/tex]

[tex]\[ x = \frac{{1 \pm \sqrt{9}}}{2} \][/tex]

[tex]\[ x = \frac{{1 \pm 3}}{2} \][/tex]

So, the solutions are:

[tex]\[ x_1 = \frac{{1 + 3}}{2} = 2 \][/tex]

[tex]\[ x_2 = \frac{{1 - 3}}{2} = -1 \][/tex]

Answer:

The correct answer would be option D, Events in which neither event is dependent upon the other.

Step-by-step explanation:

Mutually exclusive events are the events which cannot occur at the same time. If there are two events, then in mutually exclusive situation, both events can not happen at the same time. One event will happen at a time. Mutually exclusive events are also called disjoint. Both events are not dependent upon one another. The occurrence of one event would not change the occurrence of the other event. The most appropriate and suitable example of mutually exclusive events is the tossing of a coin. Either tails will come or heads. Both events can't happen at the same time, and also not both events are dependent upon each other.

Answer:

Events in which neither event is dependent upon the other

Step-by-step explanation:

Answer:

[tex]\large\boxed{y=4x+3}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of aline:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfraxc{y_2-y_1}{x_2-x_1}[/tex]

From the graph we have the points:

(-2, -5)

y-intercept (0, 3) → b = 3

Calculate the slope:

[tex]m=\dfrac{3-(-5)}{0-(-2)}=\dfrac{8}{2}=4[/tex]

Put the value of the slope and the y-intercept to the equation of a line:

[tex]y=4x+3[/tex]

The equation of the line through (-2, -5) and (0, 3) is y = 4x + 3, obtained using the point-slope form with the calculated slope and one of the given points.

To find the equation of the line passing through the given coordinates (-2, -5) and (0, 3), we can use the point-slope form of a linear equation: y - y1 = m(x - x1), where (x1, y1) are the coordinates of a point on the line, and m is the slope.

First, calculate the slope (m) using the given coordinates:

m = (y2 - y1) / (x2 - x1)

m = (3 - (-5)) / (0 - (-2)) = 8 / 2 = 4

Now, choose one of the points, let's use (-2, -5), and substitute the values into the point-slope form:

y - (-5) = 4(x - (-2))

y + 5 = 4(x + 2)

Simplify the equation:

y + 5 = 4x + 8

Isolate y:

y = 4x + 3

Therefore, the equation of the line passing through the points (-2, -5) and (0, 3) is y = 4x + 3.

[tex](\frac{-\sqrt{2}}{2},\frac{\sqrt{2}}{2})[/tex]

Step-by-step explanation:

Unit circle has a radius of 1.

So x=cos(3pi/4)=-sqrt(2)/2 and y=sin(3pi/4)=sqrt(2)/2

So the ordered pair is (-sqrt(2)/2  , sqrt(2)/2)

The terminal point for the unit circle that is determine by the [tex]$\frac{3 \pi}{4} $[/tex]   radians is

[tex]$\left( -\frac{1}{\sqrt 2}, \frac{1}{\sqrt 2} \right) . $[/tex]

We know the coordinates of the terminal point will be :

[tex]$x= \cos \left( \frac{3 \pi}{4} \right)$[/tex]    and   [tex]$y= \sin \left( \frac{3 \pi}{4} \right)$[/tex]

Therefore,

[tex]$x= \cos \left( \pi - \frac{ \pi}{4} \right)$[/tex]

[tex]$x= - \cos \frac{\pi}{4}$[/tex]

   [tex]$=-\frac{1}{\sqrt 2}$[/tex]

And

[tex]$y= \sin \left( \frac{3 \pi}{4} \right)$[/tex]

[tex]$y = \sin \left( \frac{\pi}{2} + \frac{\pi}{4} \right)$[/tex]

   [tex]$=\cos \frac{\pi}{4}$[/tex]

   [tex]$=\frac{1}{\sqrt 2}$[/tex]

Therefore the terminal points are : (x, y) = [tex]$\left( -\frac{1}{\sqrt 2}, \frac{1}{\sqrt 2} \right) . $[/tex]

Answer:

B

Step-by-step explanation:

This was originally a third degree polynomial:

[tex]2x^3+4x^2-4x+6[/tex], to be exact.

When you divide by -3, you are basically trying to determine if x + 3 is a zero of that third degree polynomial.  The quotient is always one degree lesser than the polynomial you started with, and if there is no remainder, then x + 3 is a zero of the polynomial and you could go on to factor the second degree polynoial completely to get all 3 solutions.  To perform the synthetic division, you always first bring down the number in the first position, in our case a 2.  Then multiply that 2 by -3 to get -6.

-3|  2   4   -4   6

          -6

    2    -2

So far this is what we have done.  Now we multiply the -3 by the -2 and put that up under the -4 and add:

-3|  2   4   -4   6

          -6   6

    2    -2   2

Now we multiply the -3 by the 2 to get -6 and put that up under the 6 and add:

-3|   2   4   -4   6

           -6    6  -6

      2    -2   2   0

That last row gives us the depressed polynomial, which as stated earlier here, is one degree less than what you started with:

[tex]2x^2-2x+2[/tex]
