what are the six regions of the united states

Answer:

The real solution is [tex]n=6[/tex].

Step-by-step explanation:

[tex]\cos(\frac{\pi}{2})=0[/tex] while [tex]\sin(\frac{\pi}{2})=1[/tex]

So the equation becomes:

[tex]-64=(2(0)+2i(1))^n[/tex]

[tex]-64=(0+2i)^n[/tex]

[tex]-64=(2i)^n[/tex]

We know that [tex]2^6=64[/tex]. So let's see what [tex]n=6[/tex] gives us:

[tex](2i)^6=64i^6=64i^4i^2=64(1)(-1)=-64[/tex].

[tex]-64[/tex]  is the result we wanted.

[tex]n=6[/tex] is therefore a solution.

Step-by-step explanation:

Step-by-step explanation:

Length of rectangular park = 175 m

Breadth of rectangular park = 150 m

Perimeter of park = 2 x (length + breadth)

= 2 x (175 + 150)

= 2 x 325 = 650 m

Since, cost of fencing park per meter = = Rs. 12

Therefore, cost of fencing park of 600 m = 12 x 650 = Rs. 7,800

Square park=250m

Perimeter of the square park x 4

=250x4

=1000m

So, the cost of the fencing at the park would have a rate of 20 per m = 1000x20

=20000

Answer:

66

Step-by-step explanation:

The sum of all of the angles in a triangle is 180. So all three angles would add up to 180:

(a + 21) + 57 + (a - 30) = 180

Combine like terms:

2a + 48 = 180

2a = 132

a = 66

Answer:

a+21+57+a-30=180(angle of triangle)

2a+48=180

2a=180-48

2a=132

a=132/2

a=66

then,a+21=66+21 =87

a-30=66-30 =36

Answer:

Yes, it is proportional

Step-by-step explanation:

the equation for the table is

x ÷ 28 = y

plug in the numbers for the variables

56 ÷ 28 = 2

84 ÷ 28 = 3

140 ÷ 28 = 5

Answer: 3 1/2

Step-by-step explanation: The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed. Therefore, a way to solve this problem is by multiplying (7/8 x 4/1) which will give us a final answer or result of 3.5 or 3 1/2.

Answer:

B. The function shown on the graph has a smaller rate of change and a lower starting point.

Step-by-step explanation:

✍️The function y = 6x - 1, has:

slope (m) = 6, and

Starting point/y-intercept (b) = -1

✍️Let's find the slope (m) and the starting point (y-intercept) of the function shown on the graph:

Using the points, (0, -6) and (2, 4),

Slope = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 -(-6)}{2 - 0} = \frac{10}{2} = 5 [/tex]

Slope (m) = 5

The strating value is the value of y when x = 0. In order words, it is the point at which the line of the function intercepts the y-axis.

The y-axis is intercepted at y = -6.

Therefore, the starting value (b) = -6.

Therefore, the statement correctly compares the function shown on the graph above with the function y = 6x - 1 is:

B. The function shown on the graph has a smaller rate of change and a lower starting point.

Comparing their slopes, 5 is smaller than 6.

Comparing their starting points, -6 is lower than -1.

Answer:

100 adult tickets and 140 student tickets

Step-by-step explanation:

Answer:

Sold student tickets: 130, sold adult tickets: 110

Step-by-step explanation:

Let s = number of student tickets sold,

Let a = number of adult tickets sold.

[tex]s = 20+a[/tex] (It is given that there were 20 more student tickets sold than adult tickets)

[tex]s+a=240[/tex] (It is given that the total tickets sold is 240)

[tex]20+a+a = 240[/tex]

[tex]2a=220[/tex]

[tex]a = 110[/tex]

We can use substitution to find the number of student tickets:

[tex]s+a = 240[/tex]

[tex]s + 110 = 240[/tex]

[tex]s = 130[/tex]

∴110 adult tickets and 130 student tickets were sold.

I hope this helps :)

The sum of given complex numbers in polar form as [tex]w+z=cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} )[/tex]

"The number of the type a + ib is called as complex number, where a, b are real numbers and [tex]i=\sqrt{-1}[/tex] "

"The polar form of a complex number z = x + iy is [tex]z=r(cos\theta+i~sin\theta)[/tex] where [tex]r=\sqrt{x^2+y^2}[/tex] and [tex]\theta=tan^{-1}({\frac{y}{x} })[/tex] "

For given question,

We have been given two complex numbers in polar form.

[tex]w=4(cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} ))~,z=3(cos(\frac{3\pi}{2} )+i~sin(\frac{3\pi}{2} ))[/tex]

The sum of given complex numbers would be,

[tex]w+z= 4(cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} ))+3(cos(\frac{3\pi}{2} )+i~sin(\frac{3\pi}{2} ))[/tex]

We know that

[tex]cos(\frac{\pi}{2} )=0\\\\sin(\frac{\pi}{2} )=1\\\\cos(\frac{3\pi}{2} )=0\\\\sin(\frac{\pi}{2} )=-1[/tex]

So, the sum of given complex numbers would be,

[tex]w+z\\\\= 4(cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} ))+3(cos(\frac{3\pi}{2} )+i~sin(\frac{3\pi}{2} ))\\\\=4(0+i(1))+3(0+i(-1))\\\\=4(i)+3(-i)\\\\=i\\\\=0+i[/tex]

We can write above sum of complex numbers in polar form as,

[tex]0+i=cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} )[/tex]

Therefore, the sum of given complex numbers in polar form as [tex]w+z=cos(\frac{\pi}{2} )+i~sin(\frac{\pi}{2} )[/tex]

Answer: [-4, 8]

Step-by-step explanation:

The range is the mimimum y-value, the highest y-value.

On the graph, the lowest y-value is -4 and the highest y-value is 8. Thus, when writing in the range form, the range would by [-4, 8].

The range would be in hard brackets because the range touches exactly the points of -4 and 8. If each point had an open circle, instead of a closed point, there would be soft brackets.

Answer:

See Explanation

Step-by-step explanation:

The options are missing. However, the question is still solvable.

Given

[tex]Work\ Hours = 1944[/tex]

[tex]Earnings = \$14[/tex] per hour

[tex]Estimated\ Earnings = \$28,000[/tex]

[tex]Sedan = \$25,750[/tex]

[tex]Convertible = \$27,990[/tex]

[tex]SUV = \$29,500[/tex]

First, we need to calculate her actual earnings.

This is calculated by multiplying the actual work hours (without approximation) by the earnings per hour

[tex]Total\ Earnings = 1944 * \$14[/tex]

[tex]Total\ Earnings = \$27,216[/tex]

Next, we compare this actual earnings to the amount of a Convertible

[tex]\$27216 < \$27,990[/tex]

Hence, Ashlee's conclusion is not logical because with her actual earnings, she cannot afford a Convertible
