Answer 1

Answer:

2 + i

Step-by-step explanation:

Given

[tex]\frac{4+\sqrt{16-(4)(5)} }{2}[/tex]

= [tex]\frac{4+\sqrt{16-20} }{2}[/tex]

= [tex]\frac{4+\sqrt{-4} }{2}[/tex]

= [tex]\frac{4+2i}{2}[/tex]

= 2 + i

Write a equation in slope-intercept form of the line that passes though (-5,19) and (5,13)

Answers

Answer:

y= -3/5x + 16

Step-by-step explanation:

slope intercept form: y=mx+b

1. Find the slope: rise over run so 13-19/ 5-(-5) = -3/5

M=-3.5

2. Find the y - intercept by using the point slope form: b= 16

So, y= -3/5x + 16

Answers

Answer:

I believe it is 14.

Step-by-step explanation:

Answer: The value of x is 14°

Step-by-step explanation:

Since line m is parallel to n, then then the two given angles will have the same measures. Meaning that 136 degrees has to equation (9x+10).

Set them to equal each other and solve for x.

9x + 10 = 136

Answers

Answer:

x = 10

Step-by-step explanation:

We would use postulates and theorem to figure out 34 = 3x + 4. Once you set 34 equal to 3x + 4, you would solve for x as can be shown below:

34 = 3x + 4

Subtract 4 from both sides.

30 = 3x

Divide both sides by 3.

Answer:

Step-by-step explanation:

(3x + 4)° = 34°

ABCD is a parallelogram. Work out the size of angle x

Answers

Answer:

x=47 degrees

Step-by-step explanation:

X equals 47 degrees because it is congruent to the other angle that is marked. This is because of Alternate Interior Angles.

We know AD and BC are parallel because the shape is a parallelogram, this means that the other line is a transversal. When you have a transversal going through two parallel lines there are certain rules, including Alternate Interior Angles, which are two angles on opposite sides of the transversal but both on the inside of the parallel lines.

It costs $5.08 for 4 pounds of gummy candy in bulk. How much would it cost to buy 17 pounds?

Answers

Answer:

$21.59

Step-by-step explanation:

Basically how I did it was to multiply 5.08 by 4, because that would be the cost of 16 bags and then I divided 5.08 by 4 to see how much one bag would cost. One bag costs 1.27. After I've got the answer, I added 1.27 to 20.32 and got $21.59.

2.y=x²-7x+2

Answers

Answer:

1. the vertex form of your function is f(x)= (x+-2)^2+-7

The vertex is at (2,-7)

2. So, the vertex form of your function is f(x)= (x+-7/2)^2 -41/4

The vertex is at (7/2, -41/4)

Members of the band are selling candy bars to raise money. The director uses this equation to calculate the amount of profit, p, made from selling n candy bars. p = 1.25n - 475 How many candy bars must be sold to make a profit of $950?

Answers

Answer:

380 candy bars

Step-by-step explanation:

Step one:

we are told that the expression for profit is

[tex]p = 1.25n - 475[/tex]-----------------1

the above equation represents the situation

given

profit is  $950

Required

n=number of bars

950=1.25n-475

collect like terms

950-475=1.25n

475=1.25n

divide both sides by 1.25

n=475/1.25

n= 380candy bars

Answer:

Perimeter of ∆ABR = [tex] 12 + 2\sqrt{61} [/tex]

Step-by-step explanation:

Given, A(-2, -1), B(10, -1), and R(4, 4).

Perimeter of ∆ABR = [tex] \overline{AB} + \overline{BR} + \overline{AR} [/tex]

Distance between A(-2, -1) and B(10, -1) using distance formula:

[tex] \overline{AB} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(10 -(-2))^2 + (-1 -(-1))^2} [/tex]

[tex] \overline{AB} = \sqrt{(12)^2 + (0)^2} [/tex]

[tex] \overline{AB} = \sqrt{(144 + 0)} [/tex]

[tex] \overline{AB} = \sqrt{144} = 12 [/tex]

Distance between B(10, -1) and R(4, 4):

[tex] \overline{BR} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(4 - 10)^2 + (4 -(-1))^2} [/tex]

[tex] \overline{BR} = \sqrt{(-6)^2 + (5)^2} [/tex]

[tex] \overline{BR} = \sqrt{(36 + 25)} [/tex]

[tex] \overline{BR} = \sqrt{61} [/tex]

Distance between A(-2, -1) and R(4, 4):

[tex] \overline{AR} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(4 -(-2))^2 + (4 -(-1))^2} [/tex]

[tex] \overline{AR} = \sqrt{(6)^2 + (5)^2} [/tex]

[tex] \overline{AR} = \sqrt{(36 + 25)} [/tex]

[tex] \overline{AR} = \sqrt{61} [/tex]

Perimeter of ∆ABR = [tex] \overline{AB} + \overline{BR} + \overline{AR} [/tex]

Perimeter of ∆ABR = [tex] 12 + \sqrt{61} + \sqrt{61} [/tex]

Perimeter of ∆ABR = [tex] 12 + 2\sqrt{61} [/tex]
